    Beschreibung: Genetic testing for cancer susceptibility is already part of the clinical management of families with some of the well-defined (but uncommon) inherited cancer syndromes. In cases where the risks associated with a predisposing mutation are less certain, or where there is no clearly effective intervention to offer those with a positive result, its use is more controversial. Careful evaluation of costs and benefits, and of the efficacy of interventions in those found to be at risk, is essential and is only just beginning. An immediate challenge is to ensure that both health professionals and the public understand clearly the issues involved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ponder, B -- New York, N.Y. -- Science. 1997 Nov 7;278(5340):1050-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Oncology, University of Cambridge, Addenbrooke's Hospital, Box 238, Level 3 Lab Block, Hills Road, Cambridge CB2 2QQ, UK. bajp@mole.bio.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9353178" target="_blank"〉PubMed〈/a〉

    Beschreibung: Recent evidence demonstrating multiple regions of human cerebral cortex activated by pain has prompted speculation about their individual contributions to this complex experience. To differentiate cortical areas involved in pain affect, hypnotic suggestions were used to alter selectively the unpleasantness of noxious stimuli, without changing the perceived intensity. Positron emission tomography revealed significant changes in pain-evoked activity within anterior cingulate cortex, consistent with the encoding of perceived unpleasantness, whereas primary somatosensory cortex activation was unaltered. These findings provide direct experimental evidence in humans linking frontal-lobe limbic activity with pain affect, as originally suggested by early clinical lesion studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rainville, P -- Duncan, G H -- Price, D D -- Carrier, B -- Bushnell, M C -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):968-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉D-epartement de Psychologie and Centre de Recherche en Sciences Neurologiques, Universite de Montreal, Montreal, Quebec, Canada H3C 3J7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252330" target="_blank"〉PubMed〈/a〉

    Beschreibung: Familial combined hyperlipidemia (FCHL) is a common inherited lipid disorder, affecting 1 to 2 percent of the population in Westernized societies. Individuals with FCHL have large quantities of very low density lipoprotein (VLDL) and low density lipoprotein (LDL) and develop premature coronary heart disease. A mouse model displaying some of the features of FCHL was created by crossing mice carrying the human apolipoprotein C-III (APOC3) transgene with mice deficient in the LDL receptor. A synergistic interaction between the apolipoprotein C-III and the LDL receptor defects produced large quantities of VLDL and LDL and enhanced the development of atherosclerosis. This mouse model may provide clues to the origin of human FCHL.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masucci-Magoulas, L -- Goldberg, I J -- Bisgaier, C L -- Serajuddin, H -- Francone, O L -- Breslow, J L -- Tall, A R -- HL 21006/HL/NHLBI NIH HHS/ -- HL 54591/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1997 Jan 17;275(5298):391-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Columbia University, 630 West 168 Street, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8994037" target="_blank"〉PubMed〈/a〉

    Beschreibung: Neurodegenerative disorders are characterized by extensive neuron death that leads to functional decline, but the neurobiological correlates of functional decline in normal aging are less well defined. For decades, it has been a commonly held notion that widespread neuron death in the neocortex and hippocampus is an inevitable concomitant of brain aging, but recent quantitative studies suggest that neuron death is restricted in normal aging and unlikely to account for age-related impairment of neocortical and hippocampal functions. In this article, the qualitative and quantitative differences between aging and Alzheimer's disease with respect to neuron loss are discussed, and age-related changes in functional and biochemical attributes of hippocampal circuits that might mediate functional decline in the absence of neuron death are explored. When these data are viewed comprehensively, it appears that the primary neurobiological substrates for functional impairment in aging differ in important ways from those in neurodegenerative disorders such as Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morrison, J H -- Hof, P R -- AG05138/AG/NIA NIH HHS/ -- AG06647/AG/NIA NIH HHS/ -- MHDA52145/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1997 Oct 17;278(5337):412-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurobiology of Aging Laboratories, the Fishberg Research Center for Neurobiology, and the Department of Geriatrics and Adult Development, Mount Sinai School of Medicine, New York, NY 10029, USA. morrison@cortex.neuro.mssm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9334292" target="_blank"〉PubMed〈/a〉

    Beschreibung: Long-term potentiation (LTP), a cellular model of learning and memory, requires calcium-dependent protein kinases. Induction of LTP increased the phosphorus-32 labeling of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-type glutamate receptors (AMPA-Rs), which mediate rapid excitatory synaptic transmission. This AMPA-R phosphorylation appeared to be catalyzed by Ca2+- and calmodulin-dependent protein kinase II (CaM-KII): (i) it correlated with the activation and autophosphorylation of CaM-KII, (ii) it was blocked by the CaM-KII inhibitor KN-62, and (iii) its phosphorus-32 peptide map was the same as that of GluR1 coexpressed with activated CaM-KII in HEK-293 cells. This covalent modulation of AMPA-Rs in LTP provides a postsynaptic molecular mechanism for synaptic plasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barria, A -- Muller, D -- Derkach, V -- Griffith, L C -- Soderling, T R -- NS27037/NS/NINDS NIH HHS/ -- R01 GM054408/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 27;276(5321):2042-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health Sciences University, Portland, OR 97201, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9197267" target="_blank"〉PubMed〈/a〉

    Beschreibung: A new type of inhalation aerosol, characterized by particles of small mass density and large size, permitted the highly efficient delivery of inhaled therapeutics into the systemic circulation. Particles with mass densities less than 0.4 gram per cubic centimeter and mean diameters exceeding 5 micrometers were inspired deep into the lungs and escaped the lungs' natural clearance mechanisms until the inhaled particles delivered their therapeutic payload. Inhalation of large porous insulin particles resulted in elevated systemic levels of insulin and suppressed systemic glucose levels for 96 hours, whereas small nonporous insulin particles had this effect for only 4 hours. High systemic bioavailability of testosterone was also achieved by inhalation delivery of porous particles with a mean diameter (20 micrometers) approximately 10 times that of conventional inhaled therapeutic particles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Edwards, D A -- Hanes, J -- Caponetti, G -- Hrkach, J -- Ben-Jebria, A -- Eskew, M L -- Mintzes, J -- Deaver, D -- Lotan, N -- Langer, R -- GM26698/GM/NIGMS NIH HHS/ -- HD29125/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 20;276(5320):1868-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical Engineering, Pennsylvania State University, 204 Fenske Laboratory, University Park, PA 16802, USA. dxe11@psuv.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9188534" target="_blank"〉PubMed〈/a〉

    Beschreibung: The severity of the malaria pandemic in the tropics is aggravated by the ongoing spread of parasite resistance to antimalarial drugs and mosquito resistance to insecticides. A strain of Anopheles gambiae, normally a major vector for human malaria in Africa, can encapsulate and kill the malaria parasites within a melanin-rich capsule in the mosquito midgut. Genetic mapping revealed one major and two minor quantitative trait loci (QTLs) for this encapsulation reaction. Understanding such antiparasite mechanisms in mosquitoes may lead to new strategies for malaria control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zheng, L -- Cornel, A J -- Wang, R -- Erfle, H -- Voss, H -- Ansorge, W -- Kafatos, F C -- Collins, F H -- New York, N.Y. -- Science. 1997 Apr 18;276(5311):425-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉European Molecular Biology Laboratory, Meyerhofstrasse 1, 69117 Heidelberg, Germany.

    Beschreibung: Familial adenomatous polyposis coli (FAP) is a disease characterized by the development of multiple colorectal adenomas, and affected individuals carry germline mutations in the APC gene. With the use of a conditional gene targeting system, a mouse model of FAP was created that circumvents the embryonic lethality of Apc deficiency and directs Apc inactivation specifically to the colorectal epithelium. loxP sites were inserted into the introns around Apc exon 14, and the resultant mutant allele (Apc580S) was introduced into the mouse germline. Mice homozygous for Apc580S were normal; however, upon infection of the colorectal region with an adenovirus encoding the Cre recombinase, the mice developed adenomas within 4 weeks. The adenomas showed deletion of Apc exon 14, indicating that the loss of Apc function was caused by Cre-loxP-mediated recombination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shibata, H -- Toyama, K -- Shioya, H -- Ito, M -- Hirota, M -- Hasegawa, S -- Matsumoto, H -- Takano, H -- Akiyama, T -- Toyoshima, K -- Kanamaru, R -- Kanegae, Y -- Saito, I -- Nakamura, Y -- Shiba, K -- Noda, T -- New York, N.Y. -- Science. 1997 Oct 3;278(5335):120-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Cancer Institute, Toshima-ku, Tokyo 170, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9311916" target="_blank"〉PubMed〈/a〉

    Beschreibung: Expression of Agouti protein is normally limited to the skin where it affects pigmentation, but ubiquitous expression causes obesity. An expressed sequence tag was identified that encodes Agouti-related protein, whose RNA is normally expressed in the hypothalamus and whose levels were increased eightfold in ob/ob mice. Recombinant Agouti-related protein was a potent, selective antagonist of Mc3r and Mc4r, melanocortin receptor subtypes implicated in weight regulation. Ubiquitous expression of human AGRP complementary DNA in transgenic mice caused obesity without altering pigmentation. Thus, Agouti-related protein is a neuropeptide implicated in the normal control of body weight downstream of leptin signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ollmann, M M -- Wilson, B D -- Yang, Y K -- Kerns, J A -- Chen, Y -- Gantz, I -- Barsh, G S -- EY07106/EY/NEI NIH HHS/ -- GM07365/GM/NIGMS NIH HHS/ -- P30DK-34933/DK/NIDDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1997 Oct 3;278(5335):135-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, Howard Hughes Medical Institute, Stanford University School of Medicine, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9311920" target="_blank"〉PubMed〈/a〉

    Beschreibung: Lymphocyte-specific interferon regulatory factor (LSIRF) (now called IRF4) is a transcription factor expressed only in lymphocytes. Mice deficient in IRF4 showed normal distribution of B and T lymphocyes at 4 to 5 weeks of age but developed progressive generalized lymphadenopathy. IRF4-deficient mice exhibited a profound reduction in serum immunoglobulin concentrations and did not mount detectable antibody responses. T lymphocyte function was also impaired in vivo; these mice could not generate cytotoxic or antitumor responses. Thus, IRF4 is essential for the function and homeostasis of both mature B and mature T lymphocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mittrucker, H W -- Matsuyama, T -- Grossman, A -- Kundig, T M -- Potter, J -- Shahinian, A -- Wakeham, A -- Patterson, B -- Ohashi, P S -- Mak, T W -- New York, N.Y. -- Science. 1997 Jan 24;275(5299):540-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, University of Toronto, Toronto, Ontario, M5G 2C1, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8999800" target="_blank"〉PubMed〈/a〉

    Beschreibung: Animals vary in their sensitivity to ethanol, a trait at least partly determined by genetic factors. In order to identify possible responsible genes, mice lacking Fyn, a non-receptor type tyrosine kinase, were investigated. These mice were hypersensitive to the hypnotic effect of ethanol. The administration of ethanol enhanced tyrosine phosphorylation of the N-methyl-D-aspartate receptor (NMDAR) in the hippocampus of control mice but not in Fyn-deficient mice. An acute tolerance to ethanol inhibition of NMDAR-mediated excitatory postsynaptic potentials in hippocampal slices developed in control mice but not in Fyn-deficient mice. These results indicate that Fyn affects behavioral, biochemical, and physiological responses to ethanol.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miyakawa, T -- Yagi, T -- Kitazawa, H -- Yasuda, M -- Kawai, N -- Tsuboi, K -- Niki, H -- New York, N.Y. -- Science. 1997 Oct 24;278(5338):698-701.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Neurobiology of Emotion, Brain Science Institute, RIKEN, Hirosawa, Wako-shi, Saitama-ken 351-01, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9381182" target="_blank"〉PubMed〈/a〉

    Beschreibung: Pheromones are intraspecific chemical signals important for mate attraction and discrimination. In the fruit fly Drosophila melanogaster, hydrocarbons on the cuticular surface of the animal are sexually dimorphic in both their occurrence and their effects: Female-specific molecules stimulate male sexual excitation, whereas the predominant male-specific molecule tends to inhibit male excitation. Complete feminization of the pheromone mixture produced by males was induced by targeted expression of the transformer gene in adult oenocytes (subcuticular abdominal cells) or by ubiquitous expression during early imaginal life. The resulting flies generally exhibited male heterosexual orientation but elicited homosexual courtship from other males.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ferveur, J F -- Savarit, F -- O'Kane, C J -- Sureau, G -- Greenspan, R J -- Jallon, J M -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1997 Jun 6;276(5318):1555-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mecanismes de communication, Unite de Recherche Associee-CNRS 1491, Batiment 446, Universite Paris-Sud, 91405, Orsay-Cedex, France. ferveur@ext.jussieu.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9171057" target="_blank"〉PubMed〈/a〉

    Beschreibung: It is hypothesized that collective efficacy, defined as social cohesion among neighbors combined with their willingness to intervene on behalf of the common good, is linked to reduced violence. This hypothesis was tested on a 1995 survey of 8782 residents of 343 neighborhoods in Chicago, Illinois. Multilevel analyses showed that a measure of collective efficacy yields a high between-neighborhood reliability and is negatively associated with variations in violence, when individual-level characteristics, measurement error, and prior violence are controlled. Associations of concentrated disadvantage and residential instability with violence are largely mediated by collective efficacy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sampson, R J -- Raudenbush, S W -- Earls, F -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):918-24.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Sociology, University of Chicago, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252316" target="_blank"〉PubMed〈/a〉

    Beschreibung: Computational studies suggest that acquisition of a motor skill involves learning an internal model of the dynamics of the task, which enables the brain to predict and compensate for mechanical behavior. During the hours that follow completion of practice, representation of the internal model gradually changes, becoming less fragile with respect to behavioral interference. Here, functional imaging of the brain demonstrates that within 6 hours after completion of practice, while performance remains unchanged, the brain engages new regions to perform the task; there is a shift from prefrontal regions of the cortex to the premotor, posterior parietal, and cerebellar cortex structures. This shift is specific to recall of an established motor skill and suggests that with the passage of time, there is a change in the neural representation of the internal model and that this change may underlie its increased functional stability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shadmehr, R -- Holcomb, H H -- New York, N.Y. -- Science. 1997 Aug 8;277(5327):821-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biomedical Engineering, School of Medicine, Johns Hopkins University, 720 Rutland Avenue, 419 Traylor, Baltimore, MD 21205-2195, USA. reza@bme.jhu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9242612" target="_blank"〉PubMed〈/a〉

    Beschreibung: The participation of medial temporal-lobe structures in memory performance was examined by functional magnetic resonance imaging of local blood oxygenation level-dependent signals. Signals were measured during encoding into memory complex scenes or line drawings and during retrieval from memory of previously studied line drawings or words. Encoding tasks yielded increased signals for unfamiliar information in a posterior medial-temporal region that were focused in the parahippocampal cortex. Retrieval tasks yielded increased signals for successfully remembered information in an anterior medial-temporal region that were focused in the subiculum. These results indicate that separate components of the human medial temporal-lobe memory system are active during distinct memory processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gabrieli, J D -- Brewer, J B -- Desmond, J E -- Glover, G H -- New York, N.Y. -- Science. 1997 Apr 11;276(5310):264-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology and Neuroscience Program, Stanford University, Stanford, CA 94305, USA. gabrieli@psych.stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9092477" target="_blank"〉PubMed〈/a〉

    Beschreibung: The lethal yellow (AY/a) mouse has a defect in proopiomelanocortin (POMC) signaling in the brain that leads to obesity, and is resistant to the anorexigenic effects of the hormone leptin. It has been proposed that the weight-reducing effects of leptin are thus transmitted primarily by way of POMC neurons. However, the central effects of defective POMC signaling, and the absence of leptin, on weight gain in double-mutant lethal yellow (AY/a) leptin-deficient (lepob/lepob) mice were shown to be independent and additive. Furthermore, deletion of the leptin gene restored leptin sensitivity to AY/a mice. This result implies that in the AY/a mouse, obesity is independent of leptin action, and resistance to leptin results from desensitization of leptin signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boston, B A -- Blaydon, K M -- Varnerin, J -- Cone, R D -- DK/AR517330/DK/NIDDK NIH HHS/ -- DK02404/DK/NIDDK NIH HHS/ -- HD33703/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 28;278(5343):1641-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, Oregon Health Sciences University, Portland, OR 97201, USA.

    Beschreibung: Acting in concert with individual susceptibility, environmental factors such as smoking, diet, and pollutants play a role in most human cancer. However, new molecular evidence indicates that specific groups-characterized by predisposing genetic traits or ethnicity, the very young, and women-may have heightened risk from certain exposures. This is illustrated by molecular epidemiologic studies of environmental carcinogens such as polycyclic aromatic hydrocarbons and aromatic amines. Individual genetic screening for rare high-risk traits or for more common, low-penetrant susceptibility genes is problematic and not routinely recommended. However, knowledge of the full spectrum of both genetic and acquired susceptibility in the population will be instrumental in developing health and regulatory policies that increase protection of the more susceptible groups from risks of environmental carcinogens. This will necessitate revision of current risk assessment methodologies to explicitly account for individual variation in susceptibility to environmental carcinogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perera, F P -- New York, N.Y. -- Science. 1997 Nov 7;278(5340):1068-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Environmental Health Sciences, Columbia University School of Public Health, 60 Haven Avenue, B-1, New York, NY 10032, USA. fpp1@columbia.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9353182" target="_blank"〉PubMed〈/a〉

    Beschreibung: The balance between stem cell self-renewal and differentiation is controlled by intrinsic factors and niche signals. In the Drosophila melanogaster ovary, some intrinsic factors promote germline stem cell (GSC) self-renewal, whereas others stimulate differentiation. However, it remains poorly understood how the balance between self-renewal and differentiation is controlled. Here we use D. melanogaster ovarian GSCs to demonstrate that the differentiation factor Bam controls the functional switch of the COP9 complex from self-renewal to differentiation via protein competition. The COP9 complex is composed of eight Csn subunits, Csn1-8, and removes Nedd8 modifications from target proteins. Genetic results indicated that the COP9 complex is required intrinsically for GSC self-renewal, whereas other Csn proteins, with the exception of Csn4, were also required for GSC progeny differentiation. Bam-mediated Csn4 sequestration from the COP9 complex via protein competition inactivated the self-renewing function of COP9 and allowed other Csn proteins to promote GSC differentiation. Therefore, this study reveals a protein-competition-based mechanism for controlling the balance between stem cell self-renewal and differentiation. Because numerous self-renewal factors are ubiquitously expressed throughout the stem cell lineage in various systems, protein competition may function as an important mechanism for controlling the self-renewal-to-differentiation switch.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pan, Lei -- Wang, Su -- Lu, Tinglin -- Weng, Changjiang -- Song, Xiaoqing -- Park, Joseph K -- Sun, Jin -- Yang, Zhi-Hao -- Yu, Junjing -- Tang, Hong -- McKearin, Dennis M -- Chamovitz, Daniel A -- Ni, Jianquan -- Xie, Ting -- GM64428/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Oct 9;514(7521):233-6. doi: 10.1038/nature13562.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Stowers Institute for Medical Research, 1000 East 50th Street, Kansas City, Missouri 64110, USA [2] Chinese Academy of Sciences Key Laboratory of Infection and Immunity, Institute of Biophysics, 15 Da Tun Road, Beijing 100101, China [3]. ; 1] Stowers Institute for Medical Research, 1000 East 50th Street, Kansas City, Missouri 64110, USA [2] Department of Cell Biology and Anatomy, University of Kansas School of Medicine, 3901 Rainbow Boulevard, Kansas City, Kansas 66160, USA [3]. ; 1] Center for Life Sciences, School of Medicine, Tsinghua University, Beijing 100084, China [2]. ; Stowers Institute for Medical Research, 1000 East 50th Street, Kansas City, Missouri 64110, USA. ; 1] Department of Molecular Biology and Graduate School of Biomedical Sciences, University of Texas Southwestern Medical Center, Dallas, Texas 75390-9148, USA [2] Howard Hughes Medical Institute, Chevy Chase, Maryland 20815-6789, USA. ; Center for Life Sciences, School of Medicine, Tsinghua University, Beijing 100084, China. ; 1] Stowers Institute for Medical Research, 1000 East 50th Street, Kansas City, Missouri 64110, USA [2] Chinese Academy of Sciences Key Laboratory of Infection and Immunity, Institute of Biophysics, 15 Da Tun Road, Beijing 100101, China. ; Chinese Academy of Sciences Key Laboratory of Infection and Immunity, Institute of Biophysics, 15 Da Tun Road, Beijing 100101, China. ; Department of Plant Sciences, Tel Aviv University, Tel Aviv 69978, Israel. ; 1] Stowers Institute for Medical Research, 1000 East 50th Street, Kansas City, Missouri 64110, USA [2] Department of Cell Biology and Anatomy, University of Kansas School of Medicine, 3901 Rainbow Boulevard, Kansas City, Kansas 66160, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25119050" target="_blank"〉PubMed〈/a〉

    Beschreibung: The neutralizing antibody response to influenza virus is dominated by antibodies that bind to the globular head of haemagglutinin, which undergoes a continuous antigenic drift, necessitating the re-formulation of influenza vaccines on an annual basis. Recently, several laboratories have described a new class of rare influenza-neutralizing antibodies that target a conserved site in the haemagglutinin stem. Most of these antibodies use the heavy-chain variable region VH1-69 gene, and structural data demonstrate that they bind to the haemagglutinin stem through conserved heavy-chain complementarity determining region (HCDR) residues. However, the VH1-69 antibodies are highly mutated and are produced by some but not all individuals, suggesting that several somatic mutations may be required for their development. To address this, here we characterize 197 anti-stem antibodies from a single donor, reconstruct the developmental pathways of several VH1-69 clones and identify two key elements that are required for the initial development of most VH1-69 antibodies: a polymorphic germline-encoded phenylalanine at position 54 and a conserved tyrosine at position 98 in HCDR3. Strikingly, in most cases a single proline to alanine mutation at position 52a in HCDR2 is sufficient to confer high affinity binding to the selecting H1 antigen, consistent with rapid affinity maturation. Surprisingly, additional favourable mutations continue to accumulate, increasing the breadth of reactivity and making both the initial mutations and phenylalanine at position 54 functionally redundant. These results define VH1-69 allele polymorphism, rearrangement of the VDJ gene segments and single somatic mutations as the three requirements for generating broadly neutralizing VH1-69 antibodies and reveal an unexpected redundancy in the affinity maturation process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pappas, Leontios -- Foglierini, Mathilde -- Piccoli, Luca -- Kallewaard, Nicole L -- Turrini, Filippo -- Silacci, Chiara -- Fernandez-Rodriguez, Blanca -- Agatic, Gloria -- Giacchetto-Sasselli, Isabella -- Pellicciotta, Gabriele -- Sallusto, Federica -- Zhu, Qing -- Vicenzi, Elisa -- Corti, Davide -- Lanzavecchia, Antonio -- U19 AI-057266/AI/NIAID NIH HHS/ -- England -- Nature. 2014 Dec 18;516(7531):418-22. doi: 10.1038/nature13764.

    Beschreibung: Targeted genome editing by artificial nucleases has brought the goal of site-specific transgene integration and gene correction within the reach of gene therapy. However, its application to long-term repopulating haematopoietic stem cells (HSCs) has remained elusive. Here we show that poor permissiveness to gene transfer and limited proficiency of the homology-directed DNA repair pathway constrain gene targeting in human HSCs. By tailoring delivery platforms and culture conditions we overcame these barriers and provide stringent evidence of targeted integration in human HSCs by long-term multilineage repopulation of transplanted mice. We demonstrate the therapeutic potential of our strategy by targeting a corrective complementary DNA into the IL2RG gene of HSCs from healthy donors and a subject with X-linked severe combined immunodeficiency (SCID-X1). Gene-edited HSCs sustained normal haematopoiesis and gave rise to functional lymphoid cells that possess a selective growth advantage over those carrying disruptive IL2RG mutations. These results open up new avenues for treating SCID-X1 and other diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4082311/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4082311/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Genovese, Pietro -- Schiroli, Giulia -- Escobar, Giulia -- Di Tomaso, Tiziano -- Firrito, Claudia -- Calabria, Andrea -- Moi, Davide -- Mazzieri, Roberta -- Bonini, Chiara -- Holmes, Michael C -- Gregory, Philip D -- van der Burg, Mirjam -- Gentner, Bernhard -- Montini, Eugenio -- Lombardo, Angelo -- Naldini, Luigi -- 249845/European Research Council/International -- TGT11D02/Telethon/Italy -- England -- Nature. 2014 Jun 12;510(7504):235-40. doi: 10.1038/nature13420.

    Beschreibung: Sensory regions of the brain integrate environmental cues with copies of motor-related signals important for imminent and ongoing movements. In mammals, signals propagating from the motor cortex to the auditory cortex are thought to have a critical role in normal hearing and behaviour, yet the synaptic and circuit mechanisms by which these motor-related signals influence auditory cortical activity remain poorly understood. Using in vivo intracellular recordings in behaving mice, we find that excitatory neurons in the auditory cortex are suppressed before and during movement, owing in part to increased activity of local parvalbumin-positive interneurons. Electrophysiology and optogenetic gain- and loss-of-function experiments reveal that motor-related changes in auditory cortical dynamics are driven by a subset of neurons in the secondary motor cortex that innervate the auditory cortex and are active during movement. These findings provide a synaptic and circuit basis for the motor-related corollary discharge hypothesized to facilitate hearing and auditory-guided behaviours.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4248668/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4248668/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schneider, David M -- Nelson, Anders -- Mooney, Richard -- NS079929/NS/NINDS NIH HHS/ -- R01 DC013826/DC/NIDCD NIH HHS/ -- R21 NS079929/NS/NINDS NIH HHS/ -- T32 GM008441/GM/NIGMS NIH HHS/ -- England -- Nature. 2014 Sep 11;513(7517):189-94. doi: 10.1038/nature13724.

    Beschreibung: Fertilization occurs when sperm and egg recognize each other and fuse to form a new, genetically distinct organism. The molecular basis of sperm-egg recognition is unknown, but is likely to require interactions between receptor proteins displayed on their surface. Izumo1 is an essential sperm cell-surface protein, but its receptor on the egg has not been described. Here we identify folate receptor 4 (Folr4) as the receptor for Izumo1 on the mouse egg, and propose to rename it Juno. We show that the Izumo1-Juno interaction is conserved within several mammalian species, including humans. Female mice lacking Juno are infertile and Juno-deficient eggs do not fuse with normal sperm. Rapid shedding of Juno from the oolemma after fertilization suggests a mechanism for the membrane block to polyspermy, ensuring eggs normally fuse with just a single sperm. Our discovery of an essential receptor pair at the nexus of conception provides opportunities for the rational development of new fertility treatments and contraceptives.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3998876/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3998876/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bianchi, Enrica -- Doe, Brendan -- Goulding, David -- Wright, Gavin J -- 098051/Wellcome Trust/United Kingdom -- England -- Nature. 2014 Apr 24;508(7497):483-7. doi: 10.1038/nature13203.

    Beschreibung: Huntington's disease is an autosomal dominant disease associated with a mutation in the gene encoding huntingtin (Htt) leading to expanded polyglutamine repeats of mutant Htt (mHtt) that elicit oxidative stress, neurotoxicity, and motor and behavioural changes. Huntington's disease is characterized by highly selective and profound damage to the corpus striatum, which regulates motor function. Striatal selectivity of Huntington's disease may reflect the striatally selective small G protein Rhes binding to mHtt and enhancing its neurotoxicity. Specific molecular mechanisms by which mHtt elicits neurodegeneration have been hard to determine. Here we show a major depletion of cystathionine gamma-lyase (CSE), the biosynthetic enzyme for cysteine, in Huntington's disease tissues, which may mediate Huntington's disease pathophysiology. The defect occurs at the transcriptional level and seems to reflect influences of mHtt on specificity protein 1, a transcriptional activator for CSE. Consistent with the notion of loss of CSE as a pathogenic mechanism, supplementation with cysteine reverses abnormalities in cultures of Huntington's disease tissues and in intact mouse models of Huntington's disease, suggesting therapeutic potential.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4349202/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4349202/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paul, Bindu D -- Sbodio, Juan I -- Xu, Risheng -- Vandiver, M Scott -- Cha, Jiyoung Y -- Snowman, Adele M -- Snyder, Solomon H -- MH18501/MH/NIMH NIH HHS/ -- R01 MH018501/MH/NIMH NIH HHS/ -- T32 GM007309/GM/NIGMS NIH HHS/ -- England -- Nature. 2014 May 1;509(7498):96-100. doi: 10.1038/nature13136.

    Beschreibung: The kinetochore is the crucial apparatus regulating chromosome segregation in mitosis and meiosis. Particularly in meiosis I, unlike in mitosis, sister kinetochores are captured by microtubules emanating from the same spindle pole (mono-orientation) and centromeric cohesion mediated by cohesin is protected in the following anaphase. Although meiotic kinetochore factors have been identified only in budding and fission yeasts, these molecules and their functions are thought to have diverged earlier. Therefore, a conserved mechanism for meiotic kinetochore regulation remains elusive. Here we have identified in mouse a meiosis-specific kinetochore factor that we termed MEIKIN, which functions in meiosis I but not in meiosis II or mitosis. MEIKIN plays a crucial role in both mono-orientation and centromeric cohesion protection, partly by stabilizing the localization of the cohesin protector shugoshin. These functions are mediated mainly by the activity of Polo-like kinase PLK1, which is enriched to kinetochores in a MEIKIN-dependent manner. Our integrative analysis indicates that the long-awaited key regulator of meiotic kinetochore function is Meikin, which is conserved from yeasts to humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Jihye -- Ishiguro, Kei-ichiro -- Nambu, Aya -- Akiyoshi, Bungo -- Yokobayashi, Shihori -- Kagami, Ayano -- Ishiguro, Tadashi -- Pendas, Alberto M -- Takeda, Naoki -- Sakakibara, Yogo -- Kitajima, Tomoya S -- Tanno, Yuji -- Sakuno, Takeshi -- Watanabe, Yoshinori -- England -- Nature. 2015 Jan 22;517(7535):466-71. doi: 10.1038/nature14097.

    Beschreibung: Intracellular ISG15 is an interferon (IFN)-alpha/beta-inducible ubiquitin-like modifier which can covalently bind other proteins in a process called ISGylation; it is an effector of IFN-alpha/beta-dependent antiviral immunity in mice. We previously published a study describing humans with inherited ISG15 deficiency but without unusually severe viral diseases. We showed that these patients were prone to mycobacterial disease and that human ISG15 was non-redundant as an extracellular IFN-gamma-inducing molecule. We show here that ISG15-deficient patients also display unanticipated cellular, immunological and clinical signs of enhanced IFN-alpha/beta immunity, reminiscent of the Mendelian autoinflammatory interferonopathies Aicardi-Goutieres syndrome and spondyloenchondrodysplasia. We further show that an absence of intracellular ISG15 in the patients' cells prevents the accumulation of USP18, a potent negative regulator of IFN-alpha/beta signalling, resulting in the enhancement and amplification of IFN-alpha/beta responses. Human ISG15, therefore, is not only redundant for antiviral immunity, but is a key negative regulator of IFN-alpha/beta immunity. In humans, intracellular ISG15 is IFN-alpha/beta-inducible not to serve as a substrate for ISGylation-dependent antiviral immunity, but to ensure USP18-dependent regulation of IFN-alpha/beta and prevention of IFN-alpha/beta-dependent autoinflammation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4303590/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4303590/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Xianqin -- Bogunovic, Dusan -- Payelle-Brogard, Beatrice -- Francois-Newton, Veronique -- Speer, Scott D -- Yuan, Chao -- Volpi, Stefano -- Li, Zhi -- Sanal, Ozden -- Mansouri, Davood -- Tezcan, Ilhan -- Rice, Gillian I -- Chen, Chunyuan -- Mansouri, Nahal -- Mahdaviani, Seyed Alireza -- Itan, Yuval -- Boisson, Bertrand -- Okada, Satoshi -- Zeng, Lu -- Wang, Xing -- Jiang, Hui -- Liu, Wenqiang -- Han, Tiantian -- Liu, Delin -- Ma, Tao -- Wang, Bo -- Liu, Mugen -- Liu, Jing-Yu -- Wang, Qing K -- Yalnizoglu, Dilek -- Radoshevich, Lilliana -- Uze, Gilles -- Gros, Philippe -- Rozenberg, Flore -- Zhang, Shen-Ying -- Jouanguy, Emmanuelle -- Bustamante, Jacinta -- Garcia-Sastre, Adolfo -- Abel, Laurent -- Lebon, Pierre -- Notarangelo, Luigi D -- Crow, Yanick J -- Boisson-Dupuis, Stephanie -- Casanova, Jean-Laurent -- Pellegrini, Sandra -- 1P01AI076210-01A1/AI/NIAID NIH HHS/ -- 309449/European Research Council/International -- 8UL1TR000043/TR/NCATS NIH HHS/ -- P01 AI076210/AI/NIAID NIH HHS/ -- P01 AI090935/AI/NIAID NIH HHS/ -- P01AI090935/AI/NIAID NIH HHS/ -- R00 AI106942/AI/NIAID NIH HHS/ -- R00AI106942-02/AI/NIAID NIH HHS/ -- R01 AI035237/AI/NIAID NIH HHS/ -- R37 AI095983/AI/NIAID NIH HHS/ -- R37AI095983/AI/NIAID NIH HHS/ -- U19 AI083025/AI/NIAID NIH HHS/ -- U19AI083025/AI/NIAID NIH HHS/ -- UL1 TR000043/TR/NCATS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Jan 1;517(7532):89-93. doi: 10.1038/nature13801.

    Beschreibung: Broadly, tissue regeneration is achieved in two ways: by proliferation of common differentiated cells and/or by deployment of specialized stem/progenitor cells. Which of these pathways applies is both organ- and injury-specific. Current models in the lung posit that epithelial repair can be attributed to cells expressing mature lineage markers. By contrast, here we define the regenerative role of previously uncharacterized, rare lineage-negative epithelial stem/progenitor (LNEP) cells present within normal distal lung. Quiescent LNEPs activate a DeltaNp63 (a p63 splice variant) and cytokeratin 5 remodelling program after influenza or bleomycin injury in mice. Activated cells proliferate and migrate widely to occupy heavily injured areas depleted of mature lineages, at which point they differentiate towards mature epithelium. Lineage tracing revealed scant contribution of pre-existing mature epithelial cells in such repair, whereas orthotopic transplantation of LNEPs, isolated by a definitive surface profile identified through single-cell sequencing, directly demonstrated the proliferative capacity and multipotency of this population. LNEPs require Notch signalling to activate the DeltaNp63 and cytokeratin 5 program, and subsequent Notch blockade promotes an alveolar cell fate. Persistent Notch signalling after injury led to parenchymal 'micro-honeycombing' (alveolar cysts), indicative of failed regeneration. Lungs from patients with fibrosis show analogous honeycomb cysts with evidence of hyperactive Notch signalling. Our findings indicate that distinct stem/progenitor cell pools repopulate injured tissue depending on the extent of the injury, and the outcomes of regeneration or fibrosis may depend in part on the dynamics of LNEP Notch signalling.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4312207/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4312207/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vaughan, Andrew E -- Brumwell, Alexis N -- Xi, Ying -- Gotts, Jeffrey E -- Brownfield, Doug G -- Treutlein, Barbara -- Tan, Kevin -- Tan, Victor -- Liu, Feng Chun -- Looney, Mark R -- Matthay, Michael A -- Rock, Jason R -- Chapman, Harold A -- F32 HL117600-01/HL/NHLBI NIH HHS/ -- R01 HL44712/HL/NHLBI NIH HHS/ -- U01 HL099995/HL/NHLBI NIH HHS/ -- U01 HL099999/HL/NHLBI NIH HHS/ -- U01 HL111054/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Jan 29;517(7536):621-5. doi: 10.1038/nature14112.

    Beschreibung: Despite three decades of successful, predominantly phenotype-driven discovery of the genetic causes of monogenic disorders, up to half of children with severe developmental disorders of probable genetic origin remain without a genetic diagnosis. Particularly challenging are those disorders rare enough to have eluded recognition as a discrete clinical entity, those with highly variable clinical manifestations, and those that are difficult to distinguish from other, very similar, disorders. Here we demonstrate the power of using an unbiased genotype-driven approach to identify subsets of patients with similar disorders. By studying 1,133 children with severe, undiagnosed developmental disorders, and their parents, using a combination of exome sequencing and array-based detection of chromosomal rearrangements, we discovered 12 novel genes associated with developmental disorders. These newly implicated genes increase by 10% (from 28% to 31%) the proportion of children that could be diagnosed. Clustering of missense mutations in six of these newly implicated genes suggests that normal development is being perturbed by an activating or dominant-negative mechanism. Our findings demonstrate the value of adopting a comprehensive strategy, both genome-wide and nationwide, to elucidate the underlying causes of rare genetic disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deciphering Developmental Disorders Study -- 098395/Wellcome Trust/United Kingdom -- 100140/Wellcome Trust/United Kingdom -- CZD/16/6/Chief Scientist Office/United Kingdom -- WT098051/Wellcome Trust/United Kingdom -- Department of Health/United Kingdom -- England -- Nature. 2015 Mar 12;519(7542):223-8. doi: 10.1038/nature14135.

    Beschreibung: Myocardial infarction (MI), a leading cause of death around the world, displays a complex pattern of inheritance. When MI occurs early in life, genetic inheritance is a major component to risk. Previously, rare mutations in low-density lipoprotein (LDL) genes have been shown to contribute to MI risk in individual families, whereas common variants at more than 45 loci have been associated with MI risk in the population. Here we evaluate how rare mutations contribute to early-onset MI risk in the population. We sequenced the protein-coding regions of 9,793 genomes from patients with MI at an early age (〈/=50 years in males and 〈/=60 years in females) along with MI-free controls. We identified two genes in which rare coding-sequence mutations were more frequent in MI cases versus controls at exome-wide significance. At low-density lipoprotein receptor (LDLR), carriers of rare non-synonymous mutations were at 4.2-fold increased risk for MI; carriers of null alleles at LDLR were at even higher risk (13-fold difference). Approximately 2% of early MI cases harbour a rare, damaging mutation in LDLR; this estimate is similar to one made more than 40 years ago using an analysis of total cholesterol. Among controls, about 1 in 217 carried an LDLR coding-sequence mutation and had plasma LDL cholesterol 〉 190 mg dl(-1). At apolipoprotein A-V (APOA5), carriers of rare non-synonymous mutations were at 2.2-fold increased risk for MI. When compared with non-carriers, LDLR mutation carriers had higher plasma LDL cholesterol, whereas APOA5 mutation carriers had higher plasma triglycerides. Recent evidence has connected MI risk with coding-sequence mutations at two genes functionally related to APOA5, namely lipoprotein lipase and apolipoprotein C-III (refs 18, 19). Combined, these observations suggest that, as well as LDL cholesterol, disordered metabolism of triglyceride-rich lipoproteins contributes to MI risk.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4319990/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4319990/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Do, Ron -- Stitziel, Nathan O -- Won, Hong-Hee -- Jorgensen, Anders Berg -- Duga, Stefano -- Angelica Merlini, Pier -- Kiezun, Adam -- Farrall, Martin -- Goel, Anuj -- Zuk, Or -- Guella, Illaria -- Asselta, Rosanna -- Lange, Leslie A -- Peloso, Gina M -- Auer, Paul L -- NHLBI Exome Sequencing Project -- Girelli, Domenico -- Martinelli, Nicola -- Farlow, Deborah N -- DePristo, Mark A -- Roberts, Robert -- Stewart, Alexander F R -- Saleheen, Danish -- Danesh, John -- Epstein, Stephen E -- Sivapalaratnam, Suthesh -- Hovingh, G Kees -- Kastelein, John J -- Samani, Nilesh J -- Schunkert, Heribert -- Erdmann, Jeanette -- Shah, Svati H -- Kraus, William E -- Davies, Robert -- Nikpay, Majid -- Johansen, Christopher T -- Wang, Jian -- Hegele, Robert A -- Hechter, Eliana -- Marz, Winfried -- Kleber, Marcus E -- Huang, Jie -- Johnson, Andrew D -- Li, Mingyao -- Burke, Greg L -- Gross, Myron -- Liu, Yongmei -- Assimes, Themistocles L -- Heiss, Gerardo -- Lange, Ethan M -- Folsom, Aaron R -- Taylor, Herman A -- Olivieri, Oliviero -- Hamsten, Anders -- Clarke, Robert -- Reilly, Dermot F -- Yin, Wu -- Rivas, Manuel A -- Donnelly, Peter -- Rossouw, Jacques E -- Psaty, Bruce M -- Herrington, David M -- Wilson, James G -- Rich, Stephen S -- Bamshad, Michael J -- Tracy, Russell P -- Cupples, L Adrienne -- Rader, Daniel J -- Reilly, Muredach P -- Spertus, John A -- Cresci, Sharon -- Hartiala, Jaana -- Tang, W H Wilson -- Hazen, Stanley L -- Allayee, Hooman -- Reiner, Alex P -- Carlson, Christopher S -- Kooperberg, Charles -- Jackson, Rebecca D -- Boerwinkle, Eric -- Lander, Eric S -- Schwartz, Stephen M -- Siscovick, David S -- McPherson, Ruth -- Tybjaerg-Hansen, Anne -- Abecasis, Goncalo R -- Watkins, Hugh -- Nickerson, Deborah A -- Ardissino, Diego -- Sunyaev, Shamil R -- O'Donnell, Christopher J -- Altshuler, David -- Gabriel, Stacey -- Kathiresan, Sekar -- 090532/Wellcome Trust/United Kingdom -- 095552/Wellcome Trust/United Kingdom -- 5U54HG003067-11/HG/NHGRI NIH HHS/ -- G-0907/Parkinson's UK/United Kingdom -- K08 HL114642/HL/NHLBI NIH HHS/ -- K08HL114642/HL/NHLBI NIH HHS/ -- P01 HL076491/HL/NHLBI NIH HHS/ -- P01 HL098055/HL/NHLBI NIH HHS/ -- R01 HL107816/HL/NHLBI NIH HHS/ -- R01HL107816/HL/NHLBI NIH HHS/ -- RC2 HL-102923/HL/NHLBI NIH HHS/ -- RC2 HL-102924/HL/NHLBI NIH HHS/ -- RC2 HL-102925/HL/NHLBI NIH HHS/ -- RC2 HL-102926/HL/NHLBI NIH HHS/ -- RC2 HL-103010/HL/NHLBI NIH HHS/ -- T32 HL007208/HL/NHLBI NIH HHS/ -- T32HL00720/HL/NHLBI NIH HHS/ -- T32HL007604/HL/NHLBI NIH HHS/ -- UL1 TR000439/TR/NCATS NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2015 Feb 5;518(7537):102-6. doi: 10.1038/nature13917.

    Beschreibung: TP53 is commonly altered in human cancer, and Tp53 reactivation suppresses tumours in vivo in mice (TP53 and Tp53 are also known as p53). This strategy has proven difficult to implement therapeutically, and here we examine an alternative strategy by manipulating the p53 family members, Tp63 and Tp73 (also known as p63 and p73, respectively). The acidic transactivation-domain-bearing (TA) isoforms of p63 and p73 structurally and functionally resemble p53, whereas the DeltaN isoforms (lacking the acidic transactivation domain) of p63 and p73 are frequently overexpressed in cancer and act primarily in a dominant-negative fashion against p53, TAp63 and TAp73 to inhibit their tumour-suppressive functions. The p53 family interacts extensively in cellular processes that promote tumour suppression, such as apoptosis and autophagy, thus a clear understanding of this interplay in cancer is needed to treat tumours with alterations in the p53 pathway. Here we show that deletion of the DeltaN isoforms of p63 or p73 leads to metabolic reprogramming and regression of p53-deficient tumours through upregulation of IAPP, the gene that encodes amylin, a 37-amino-acid peptide co-secreted with insulin by the beta cells of the pancreas. We found that IAPP is causally involved in this tumour regression and that amylin functions through the calcitonin receptor (CalcR) and receptor activity modifying protein 3 (RAMP3) to inhibit glycolysis and induce reactive oxygen species and apoptosis. Pramlintide, a synthetic analogue of amylin that is currently used to treat type 1 and type 2 diabetes, caused rapid tumour regression in p53-deficient thymic lymphomas, representing a novel strategy to target p53-deficient cancers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4312210/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4312210/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Venkatanarayan, Avinashnarayan -- Raulji, Payal -- Norton, William -- Chakravarti, Deepavali -- Coarfa, Cristian -- Su, Xiaohua -- Sandur, Santosh K -- Ramirez, Marc S -- Lee, Jaehuk -- Kingsley, Charles V -- Sananikone, Eliot F -- Rajapakshe, Kimal -- Naff, Katherine -- Parker-Thornburg, Jan -- Bankson, James A -- Tsai, Kenneth Y -- Gunaratne, Preethi H -- Flores, Elsa R -- CA-16672/CA/NCI NIH HHS/ -- P30 CA016672/CA/NCI NIH HHS/ -- P50CA136411/CA/NCI NIH HHS/ -- R01 CA134796/CA/NCI NIH HHS/ -- R01 CA160394/CA/NCI NIH HHS/ -- R01CA134796/CA/NCI NIH HHS/ -- R01CA160394/CA/NCI NIH HHS/ -- England -- Nature. 2015 Jan 29;517(7536):626-30. doi: 10.1038/nature13910.

    Beschreibung: Establishing the hippocampal cellular ensemble that represents an animal's environment involves the emergence and disappearance of place fields in specific CA1 pyramidal neurons, and the acquisition of different spatial firing properties across the active population. While such firing flexibility and diversity have been linked to spatial memory, attention and task performance, the cellular and network origin of these place cell features is unknown. Basic integrate-and-fire models of place firing propose that such features result solely from varying inputs to place cells, but recent studies suggest instead that place cells themselves may play an active role through regenerative dendritic events. However, owing to the difficulty of performing functional recordings from place cell dendrites, no direct evidence of regenerative dendritic events exists, leaving any possible connection to place coding unknown. Using multi-plane two-photon calcium imaging of CA1 place cell somata, axons and dendrites in mice navigating a virtual environment, here we show that regenerative dendritic events do exist in place cells of behaving mice, and, surprisingly, their prevalence throughout the arbour is highly spatiotemporally variable. Furthermore, we show that the prevalence of such events predicts the spatial precision and persistence or disappearance of place fields. This suggests that the dynamics of spiking throughout the dendritic arbour may play a key role in forming the hippocampal representation of space.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4289090/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4289090/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sheffield, Mark E J -- Dombeck, Daniel A -- 1R01MH101297/MH/NIMH NIH HHS/ -- R01 MH101297/MH/NIMH NIH HHS/ -- England -- Nature. 2015 Jan 8;517(7533):200-4. doi: 10.1038/nature13871.

    Beschreibung: Cytotoxic chemotherapy is effective in debulking tumour masses initially; however, in some patients tumours become progressively unresponsive after multiple treatment cycles. Previous studies have demonstrated that cancer stem cells (CSCs) are selectively enriched after chemotherapy through enhanced survival. Here we reveal a new mechanism by which bladder CSCs actively contribute to therapeutic resistance via an unexpected proliferative response to repopulate residual tumours between chemotherapy cycles, using human bladder cancer xenografts. Further analyses demonstrate the recruitment of a quiescent label-retaining pool of CSCs into cell division in response to chemotherapy-induced damages, similar to mobilization of normal stem cells during wound repair. While chemotherapy effectively induces apoptosis, associated prostaglandin E2 (PGE2) release paradoxically promotes neighbouring CSC repopulation. This repopulation can be abrogated by a PGE2-neutralizing antibody and celecoxib drug-mediated blockade of PGE2 signalling. In vivo administration of the cyclooxygenase-2 (COX2) inhibitor celecoxib effectively abolishes a PGE2- and COX2-mediated wound response gene signature, and attenuates progressive manifestation of chemoresistance in xenograft tumours, including primary xenografts derived from a patient who was resistant to chemotherapy. Collectively, these findings uncover a new underlying mechanism that models the progressive development of clinical chemoresistance, and implicate an adjunctive therapy to enhance chemotherapeutic response of bladder urothelial carcinomas by abrogating early tumour repopulation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4465385/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4465385/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kurtova, Antonina V -- Xiao, Jing -- Mo, Qianxing -- Pazhanisamy, Senthil -- Krasnow, Ross -- Lerner, Seth P -- Chen, Fengju -- Roh, Terrence T -- Lay, Erica -- Ho, Philip Levy -- Chan, Keith Syson -- AI036211/AI/NIAID NIH HHS/ -- CA125123/CA/NCI NIH HHS/ -- CA129640/CA/NCI NIH HHS/ -- CA175397/CA/NCI NIH HHS/ -- R00 CA129640/CA/NCI NIH HHS/ -- R01 CA175397/CA/NCI NIH HHS/ -- RR024574/RR/NCRR NIH HHS/ -- England -- Nature. 2015 Jan 8;517(7533):209-13. doi: 10.1038/nature14034.

    Beschreibung: We document that China's One-Child Policy (OCP), one of the most radical approaches to limiting population growth, has produced significantly less trusting, less trustworthy, more risk-averse, less competitive, more pessimistic, and less conscientious individuals. Our data were collected from economics experiments conducted with 421 individuals born just before and just after the OCP's introduction in 1979. Surveys to elicit personality traits were also used. We used the exogenous imposition of the OCP to identify the causal impact of being an only child, net of family background effects. The OCP thus has significant ramifications for Chinese society.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cameron, L -- Erkal, N -- Gangadharan, L -- Meng, X -- New York, N.Y. -- Science. 2013 Feb 22;339(6122):953-7. doi: 10.1126/science.1230221.

    Beschreibung: Glycosylated alpha-dystroglycan (alpha-DG) serves as cellular entry receptor for multiple pathogens, and defects in its glycosylation cause hereditary Walker-Warburg syndrome (WWS). At least eight proteins are critical to glycosylate alpha-DG, but many genes mutated in WWS remain unknown. To identify modifiers of alpha-DG, we performed a haploid screen for Lassa virus entry, a hemorrhagic fever virus causing thousands of deaths annually that hijacks glycosylated alpha-DG to enter cells. In complementary screens, we profiled cells for absence of alpha-DG carbohydrate chains or biochemically related glycans. This revealed virus host factors and a suite of glycosylation units, including all known Walker-Warburg genes and five additional factors critical for the modification of alpha-DG. Our findings accentuate the complexity of this posttranslational feature and point out genes defective in dystroglycanopathies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3919138/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3919138/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jae, Lucas T -- Raaben, Matthijs -- Riemersma, Moniek -- van Beusekom, Ellen -- Blomen, Vincent A -- Velds, Arno -- Kerkhoven, Ron M -- Carette, Jan E -- Topaloglu, Haluk -- Meinecke, Peter -- Wessels, Marja W -- Lefeber, Dirk J -- Whelan, Sean P -- van Bokhoven, Hans -- Brummelkamp, Thijn R -- AI057159/AI/NIAID NIH HHS/ -- AI081842/AI/NIAID NIH HHS/ -- R01 AI081842/AI/NIAID NIH HHS/ -- U54 AI057159/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Apr 26;340(6131):479-83. doi: 10.1126/science.1233675.

    Beschreibung: The growing prevalence of overeating disorders is a key contributor to the worldwide obesity epidemic. Dysfunction of particular neural circuits may trigger deviations from adaptive feeding behaviors. The lateral hypothalamus (LH) is a crucial neural substrate for motivated behavior, including feeding, but the precise functional neurocircuitry that controls LH neuronal activity to engage feeding has not been defined. We observed that inhibitory synaptic inputs from the extended amygdala preferentially innervate and suppress the activity of LH glutamatergic neurons to control food intake. These findings help explain how dysregulated activity at a number of unique nodes can result in a cascading failure within a defined brain network to produce maladaptive feeding.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4131546/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4131546/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jennings, Joshua H -- Rizzi, Giorgio -- Stamatakis, Alice M -- Ung, Randall L -- Stuber, Garret D -- AA011605/AA/NIAAA NIH HHS/ -- AA022234/AA/NIAAA NIH HHS/ -- DA032750/DA/NIDA NIH HHS/ -- DA034472/DA/NIDA NIH HHS/ -- F31 DA034472/DA/NIDA NIH HHS/ -- NS007431/NS/NINDS NIH HHS/ -- P30 NS045892/NS/NINDS NIH HHS/ -- P50 AA011605/AA/NIAAA NIH HHS/ -- R01 DA032750/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2013 Sep 27;341(6153):1517-21. doi: 10.1126/science.1241812.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24072922" target="_blank"〉PubMed〈/a〉

    Beschreibung: Color patterns of bird plumage affect animal behavior and speciation. Diverse patterns are present in different species and within the individual. Here, we study the cellular and molecular basis of feather pigment pattern formation. Melanocyte progenitors are distributed as a horizontal ring in the proximal follicle, sending melanocytes vertically up into the epithelial cylinder, which gradually emerges as feathers grow. Different pigment patterns form by modulating the presence, arrangement, or differentiation of melanocytes. A layer of peripheral pulp further regulates pigmentation via patterned agouti expression. Lifetime feather cyclic regeneration resets pigment patterns for physiological needs. Thus, the evolution of stem cell niche topology allows complex pigment patterning through combinatorial co-option of simple regulatory mechanisms.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4144997/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4144997/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, S J -- Foley, J -- Jiang, T X -- Yeh, C Y -- Wu, P -- Foley, A -- Yen, C M -- Huang, Y C -- Cheng, H C -- Chen, C F -- Reeder, B -- Jee, S H -- Widelitz, R B -- Chuong, C M -- AR060306/AR/NIAMS NIH HHS/ -- AR42177/AR/NIAMS NIH HHS/ -- AR47364/AR/NIAMS NIH HHS/ -- R01 AR042177/AR/NIAMS NIH HHS/ -- R01 AR047364/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Jun 21;340(6139):1442-5. doi: 10.1126/science.1230374.

    Beschreibung: Whereas reward (appetitiveness) and aversiveness (punishment) have been distinguished as two discrete dimensions within psychology and behavior, physiological and computational models of their neural representation have treated them as opposite sides of a single continuous dimension of "value." Here, I show that although dopamine neurons of the primate ventral midbrain are activated by evidence for reward and suppressed by evidence against reward, they are insensitive to aversiveness. This indicates that reward and aversiveness are represented independently as two dimensions, even by neurons that are closely related to motor function. Because theory and experiment support the existence of opponent neural representations for value, the present results imply four types of value-sensitive neurons corresponding to reward-ON (dopamine), reward-OFF, aversive-ON, and aversive-OFF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fiorillo, Christopher D -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Aug 2;341(6145):546-9. doi: 10.1126/science.1238699.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bio and Brain Engineering, KAIST (Korea Advanced Institute of Science and Technology), Yuseong-gu, Daejeon, Republic of Korea. fiorillo@kaist.ac.kr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23908236" target="_blank"〉PubMed〈/a〉

    Beschreibung: Cramer et al. (Reports, 23 March 2012, p. 1503; published online 9 February 2012) demonstrated in a mouse model for Alzheimer's disease (AD) that treatment of APP/PS1DeltaE9 mice with bexarotene decreased Abeta pathology and ameliorated memory deficits. We confirm the reversal of memory deficits in APP/PS1DeltaE9 mice expressing human APOE3 or APOE4 to the levels of their nontransgenic controls and the significant decrease of interstitial fluid Abeta, but not the effects on amyloid deposition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4086452/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4086452/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fitz, Nicholas F -- Cronican, Andrea A -- Lefterov, Iliya -- Koldamova, Radosveta -- F32AG034031/AG/NIA NIH HHS/ -- R01 AG037481/AG/NIA NIH HHS/ -- R01 AG037919/AG/NIA NIH HHS/ -- R01AG037481/AG/NIA NIH HHS/ -- R01AG037919/AG/NIA NIH HHS/ -- R21 ES021243/ES/NIEHS NIH HHS/ -- R21ES021243/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 2013 May 24;340(6135):924-c. doi: 10.1126/science.1235809.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Environmental and Occupational Health, University of Pittsburgh, 100 Technology Drive, Pittsburgh, PA 15219, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23704552" target="_blank"〉PubMed〈/a〉

    Beschreibung: Leathers and Olson (Reports, 5 October 2012, p. 132) draw the strong conclusion that neurons in the monkey lateral intraparietal (LIP) cortical area encode only cue salience, and not action value, during value-based decision-making. Although their findings regarding cue salience are interesting, their broader conclusions are problematic because (i) their primary conclusion is based on responses observed during a brief interval at the beginning of behavioral trials but is extended to all subsequent temporal epochs and (ii) the authors failed to replicate basic hallmarks of LIP physiology observed in those subsequent temporal epochs by many laboratories.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4045496/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4045496/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Newsome, William T -- Glimcher, Paul W -- Gottlieb, Jacqueline -- Lee, Daeyeol -- Platt, Michael L -- R01 MH096875/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2013 Apr 26;340(6131):430. doi: 10.1126/science.1233214.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology and Howard Hughes Medical Institute, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23620037" target="_blank"〉PubMed〈/a〉

    Beschreibung: Although reconsolidation opens up new avenues to erase excessive fear memory, subtle boundary conditions put constraints on retrieval-induced plasticity. Reconsolidation may only take place when memory reactivation involves an experience that engages new learning (prediction error). Thus far, it has not been possible to determine the optimal degree of novelty required for destabilizing the memory. The occurrence of prediction error could only be inferred from the observation of a reconsolidation process itself. Here, we provide a noninvasive index of memory destabilization that is independent from the occurrence of reconsolidation. Using this index, we show in humans that prediction error is (i) a necessary condition for reconsolidation of associative fear memory and (ii) determined by the interaction between original learning and retrieval. Insight into the process of memory updating is crucial for understanding the optimal and boundary conditions on reconsolidation and provides a clear guide for the development of reconsolidation-based treatments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sevenster, Dieuwke -- Beckers, Tom -- Kindt, Merel -- New York, N.Y. -- Science. 2013 Feb 15;339(6121):830-3. doi: 10.1126/science.1231357.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Clinical Psychology, University of Amsterdam, Amsterdam, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23413355" target="_blank"〉PubMed〈/a〉

    Beschreibung: Melanocortin receptor accessory proteins (MRAPs) modulate signaling of melanocortin receptors in vitro. To investigate the physiological role of brain-expressed melanocortin 2 receptor accessory protein 2 (MRAP2), we characterized mice with whole-body and brain-specific targeted deletion of Mrap2, both of which develop severe obesity at a young age. Mrap2 interacts directly with melanocortin 4 receptor (Mc4r), a protein previously implicated in mammalian obesity, and it enhances Mc4r-mediated generation of the second messenger cyclic adenosine monophosphate, suggesting that alterations in Mc4r signaling may be one mechanism underlying the association between Mrap2 disruption and obesity. In a study of humans with severe, early-onset obesity, we found four rare, potentially pathogenic genetic variants in MRAP2, suggesting that the gene may also contribute to body weight regulation in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3788688/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3788688/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Asai, Masato -- Ramachandrappa, Shwetha -- Joachim, Maria -- Shen, Yuan -- Zhang, Rong -- Nuthalapati, Nikhil -- Ramanathan, Visali -- Strochlic, David E -- Ferket, Peter -- Linhart, Kirsten -- Ho, Caroline -- Novoselova, Tatiana V -- Garg, Sumedha -- Ridderstrale, Martin -- Marcus, Claude -- Hirschhorn, Joel N -- Keogh, Julia M -- O'Rahilly, Stephen -- Chan, Li F -- Clark, Adrian J -- Farooqi, I Sadaf -- Majzoub, Joseph A -- 098497/Wellcome Trust/United Kingdom -- G0802796/Medical Research Council/United Kingdom -- G0900554/Medical Research Council/United Kingdom -- G9824984/Medical Research Council/United Kingdom -- P30-HD18655/HD/NICHD NIH HHS/ -- R01 DK075787/DK/NIDDK NIH HHS/ -- R01DK075787/DK/NIDDK NIH HHS/ -- T32 DK007699/DK/NIDDK NIH HHS/ -- T32 MH020017/MH/NIMH NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2013 Jul 19;341(6143):275-8. doi: 10.1126/science.1233000.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Endocrinology, Department of Medicine, Boston Children's Hospital, Harvard Medical School, 300 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23869016" target="_blank"〉PubMed〈/a〉

    Beschreibung: The poor often behave in less capable ways, which can further perpetuate poverty. We hypothesize that poverty directly impedes cognitive function and present two studies that test this hypothesis. First, we experimentally induced thoughts about finances and found that this reduces cognitive performance among poor but not in well-off participants. Second, we examined the cognitive function of farmers over the planting cycle. We found that the same farmer shows diminished cognitive performance before harvest, when poor, as compared with after harvest, when rich. This cannot be explained by differences in time available, nutrition, or work effort. Nor can it be explained with stress: Although farmers do show more stress before harvest, that does not account for diminished cognitive performance. Instead, it appears that poverty itself reduces cognitive capacity. We suggest that this is because poverty-related concerns consume mental resources, leaving less for other tasks. These data provide a previously unexamined perspective and help explain a spectrum of behaviors among the poor. We discuss some implications for poverty policy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mani, Anandi -- Mullainathan, Sendhil -- Shafir, Eldar -- Zhao, Jiaying -- New York, N.Y. -- Science. 2013 Aug 30;341(6149):976-80. doi: 10.1126/science.1238041.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Economics, University of Warwick, Coventry, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23990553" target="_blank"〉PubMed〈/a〉

    Beschreibung: Although cortico-striato-thalamo-cortical (CSTC) circuit dysregulation is correlated with obsessive compulsive disorder (OCD), causation cannot be tested in humans. We used optogenetics in mice to simulate CSTC hyperactivation observed in OCD patients. Whereas acute orbitofrontal cortex (OFC)-ventromedial striatum (VMS) stimulation did not produce repetitive behaviors, repeated hyperactivation over multiple days generated a progressive increase in grooming, a mouse behavior related to OCD. Increased grooming persisted for 2 weeks after stimulation cessation. The grooming increase was temporally coupled with a progressive increase in light-evoked firing of postsynaptic VMS cells. Both increased grooming and evoked firing were reversed by chronic fluoxetine, a first-line OCD treatment. Brief but repeated episodes of abnormal circuit activity may thus set the stage for the development of persistent psychopathology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3954809/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3954809/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ahmari, Susanne E -- Spellman, Timothy -- Douglass, Neria L -- Kheirbek, Mazen A -- Simpson, H Blair -- Deisseroth, Karl -- Gordon, Joshua A -- Hen, Rene -- K01 MH099371/MH/NIMH NIH HHS/ -- K01MH099371/MH/NIMH NIH HHS/ -- K08 MH087718/MH/NIMH NIH HHS/ -- K08MH087718/MH/NIMH NIH HHS/ -- K24 MH091555/MH/NIMH NIH HHS/ -- R01 MH096274/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Jun 7;340(6137):1234-9. doi: 10.1126/science.1234733.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, Columbia University College of Physicians and Surgeons, New York, NY 10032, USA. sea2103@columbia.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23744948" target="_blank"〉PubMed〈/a〉

    Beschreibung: Wiskott-Aldrich syndrome (WAS) is an inherited immunodeficiency caused by mutations in the gene encoding WASP, a protein regulating the cytoskeleton. Hematopoietic stem/progenitor cell (HSPC) transplants can be curative, but, when matched donors are unavailable, infusion of autologous HSPCs modified ex vivo by gene therapy is an alternative approach. We used a lentiviral vector encoding functional WASP to genetically correct HSPCs from three WAS patients and reinfused the cells after a reduced-intensity conditioning regimen. All three patients showed stable engraftment of WASP-expressing cells and improvements in platelet counts, immune functions, and clinical scores. Vector integration analyses revealed highly polyclonal and multilineage haematopoiesis resulting from the gene-corrected HSPCs. Lentiviral gene therapy did not induce selection of integrations near oncogenes, and no aberrant clonal expansion was observed after 20 to 32 months. Although extended clinical observation is required to establish long-term safety, lentiviral gene therapy represents a promising treatment for WAS.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4375961/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4375961/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aiuti, Alessandro -- Biasco, Luca -- Scaramuzza, Samantha -- Ferrua, Francesca -- Cicalese, Maria Pia -- Baricordi, Cristina -- Dionisio, Francesca -- Calabria, Andrea -- Giannelli, Stefania -- Castiello, Maria Carmina -- Bosticardo, Marita -- Evangelio, Costanza -- Assanelli, Andrea -- Casiraghi, Miriam -- Di Nunzio, Sara -- Callegaro, Luciano -- Benati, Claudia -- Rizzardi, Paolo -- Pellin, Danilo -- Di Serio, Clelia -- Schmidt, Manfred -- Von Kalle, Christof -- Gardner, Jason -- Mehta, Nalini -- Neduva, Victor -- Dow, David J -- Galy, Anne -- Miniero, Roberto -- Finocchi, Andrea -- Metin, Ayse -- Banerjee, Pinaki P -- Orange, Jordan S -- Galimberti, Stefania -- Valsecchi, Maria Grazia -- Biffi, Alessandra -- Montini, Eugenio -- Villa, Anna -- Ciceri, Fabio -- Roncarolo, Maria Grazia -- Naldini, Luigi -- R01 AI067946/AI/NIAID NIH HHS/ -- TGT11D01/Telethon/Italy -- TGT11D02/Telethon/Italy -- New York, N.Y. -- Science. 2013 Aug 23;341(6148):1233151. doi: 10.1126/science.1233151.

    Beschreibung: Mani et al. (Research Articles, 30 August, p. 976) presented laboratory experiments that aimed to show that poverty-related worries impede cognitive functioning. A reanalysis without dichotomization of income fails to corroborate their findings and highlights spurious interactions between income and experimental manipulation due to ceiling effects caused by short and easy tests. This suggests that effects of financial worries are not limited to the poor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wicherts, Jelte M -- Scholten, Annemarie Zand -- New York, N.Y. -- Science. 2013 Dec 6;342(6163):1169. doi: 10.1126/science.1246680.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Jelte Wicherts, Department of Methodology and Statistics, Tilburg University, P.O.

    Beschreibung: gamma-aminobutyric acid-mediated (GABAergic) inhibition plays a critical role in shaping neuronal activity in the neocortex. Numerous experimental investigations have examined perisomatic inhibitory synapses, which control action potential output from pyramidal neurons. However, most inhibitory synapses in the neocortex are formed onto pyramidal cell dendrites, where theoretical studies suggest they may focally regulate cellular activity. The precision of GABAergic control over dendritic electrical and biochemical signaling is unknown. By using cell type-specific optical stimulation in combination with two-photon calcium (Ca(2+)) imaging, we show that somatostatin-expressing interneurons exert compartmentalized control over postsynaptic Ca(2+) signals within individual dendritic spines. This highly focal inhibitory action is mediated by a subset of GABAergic synapses that directly target spine heads. GABAergic inhibition thus participates in localized control of dendritic electrical and biochemical signaling.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3752161/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3752161/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chiu, Chiayu Q -- Lur, Gyorgy -- Morse, Thomas M -- Carnevale, Nicholas T -- Ellis-Davies, Graham C R -- Higley, Michael J -- DC009977/DC/NIDCD NIH HHS/ -- GM053395/GM/NIGMS NIH HHS/ -- K01 MH097961/MH/NIMH NIH HHS/ -- MH099045/MH/NIMH NIH HHS/ -- NS011613/NS/NINDS NIH HHS/ -- NS069720/NS/NINDS NIH HHS/ -- R01 DC009977/DC/NIDCD NIH HHS/ -- R01 GM053395/GM/NIGMS NIH HHS/ -- R01 MH099045/MH/NIMH NIH HHS/ -- R01 NS011613/NS/NINDS NIH HHS/ -- R01 NS069720/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2013 May 10;340(6133):759-62. doi: 10.1126/science.1234274.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Yale School of Medicine, New Haven, CT 06510, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23661763" target="_blank"〉PubMed〈/a〉

    Beschreibung: The relationship between phenotype and fitness can be visualized as a rugged landscape. Multiple fitness peaks on this landscape are predicted to drive early bursts of niche diversification during adaptive radiation. We measured the adaptive landscape in a nascent adaptive radiation of Cyprinodon pupfishes endemic to San Salvador Island, Bahamas, and found multiple coexisting high-fitness regions driven by increased competition at high densities, supporting the early burst model. Hybrids resembling the generalist phenotype were isolated on a local fitness peak separated by a valley from a higher-fitness region corresponding to trophic specialization. This complex landscape could explain both the rarity of specialists across many similar environments due to stabilizing selection on generalists and the rapid morphological diversification rate of specialists due to their higher fitness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, Christopher H -- Wainwright, Peter C -- New York, N.Y. -- Science. 2013 Jan 11;339(6116):208-11. doi: 10.1126/science.1227710.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Evolution and Ecology and Center for Population Biology, University of California, One Shields Avenue, Davis, CA, USA. chmartin@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23307743" target="_blank"〉PubMed〈/a〉

    Beschreibung: Consistent, high-level, vaccine-induced protection against human malaria has only been achieved by inoculation of Plasmodium falciparum (Pf) sporozoites (SPZ) by mosquito bites. We report that the PfSPZ Vaccine--composed of attenuated, aseptic, purified, cryopreserved PfSPZ--was safe and well tolerated when administered four to six times intravenously (IV) to 40 adults. Zero of six subjects receiving five doses and three of nine subjects receiving four doses of 1.35 x 10(5) PfSPZ Vaccine and five of six nonvaccinated controls developed malaria after controlled human malaria infection (P = 0.015 in the five-dose group and P = 0.028 for overall, both versus controls). PfSPZ-specific antibody and T cell responses were dose-dependent. These data indicate that there is a dose-dependent immunological threshold for establishing high-level protection against malaria that can be achieved with IV administration of a vaccine that is safe and meets regulatory standards.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seder, Robert A -- Chang, Lee-Jah -- Enama, Mary E -- Zephir, Kathryn L -- Sarwar, Uzma N -- Gordon, Ingelise J -- Holman, LaSonji A -- James, Eric R -- Billingsley, Peter F -- Gunasekera, Anusha -- Richman, Adam -- Chakravarty, Sumana -- Manoj, Anita -- Velmurugan, Soundarapandian -- Li, MingLin -- Ruben, Adam J -- Li, Tao -- Eappen, Abraham G -- Stafford, Richard E -- Plummer, Sarah H -- Hendel, Cynthia S -- Novik, Laura -- Costner, Pamela J M -- Mendoza, Floreliz H -- Saunders, Jamie G -- Nason, Martha C -- Richardson, Jason H -- Murphy, Jittawadee -- Davidson, Silas A -- Richie, Thomas L -- Sedegah, Martha -- Sutamihardja, Awalludin -- Fahle, Gary A -- Lyke, Kirsten E -- Laurens, Matthew B -- Roederer, Mario -- Tewari, Kavita -- Epstein, Judith E -- Sim, B Kim Lee -- Ledgerwood, Julie E -- Graham, Barney S -- Hoffman, Stephen L -- VRC 312 Study Team -- 3R44AI055229-06S1/AI/NIAID NIH HHS/ -- 4R44AI055229-08/AI/NIAID NIH HHS/ -- 5R44AI058499-05/AI/NIAID NIH HHS/ -- N01-AI-40096/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1359-65. doi: 10.1126/science.1241800.

    Beschreibung: We used network-based diffusion analysis to reveal the cultural spread of a naturally occurring foraging innovation, lobtail feeding, through a population of humpback whales (Megaptera novaeangliae) over a period of 27 years. Support for models with a social transmission component was 6 to 23 orders of magnitude greater than for models without. The spatial and temporal distribution of sand lance, a prey species, was also important in predicting the rate of acquisition. Our results, coupled with existing knowledge about song traditions, show that this species can maintain multiple independently evolving traditions in its populations. These insights strengthen the case that cetaceans represent a peak in the evolution of nonhuman culture, independent of the primate lineage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Allen, Jenny -- Weinrich, Mason -- Hoppitt, Will -- Rendell, Luke -- New York, N.Y. -- Science. 2013 Apr 26;340(6131):485-8. doi: 10.1126/science.1231976.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sea Mammal Research Unit and Centre for Social Learning and Cognitive Evolution, School of Biology, University of St Andrews, Fife, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23620054" target="_blank"〉PubMed〈/a〉

    Beschreibung: Kwashiorkor, an enigmatic form of severe acute malnutrition, is the consequence of inadequate nutrient intake plus additional environmental insults. To investigate the role of the gut microbiome, we studied 317 Malawian twin pairs during the first 3 years of life. During this time, half of the twin pairs remained well nourished, whereas 43% became discordant, and 7% manifested concordance for acute malnutrition. Both children in twin pairs discordant for kwashiorkor were treated with a peanut-based, ready-to-use therapeutic food (RUTF). Time-series metagenomic studies revealed that RUTF produced a transient maturation of metabolic functions in kwashiorkor gut microbiomes that regressed when administration of RUTF was stopped. Previously frozen fecal communities from several discordant pairs were each transplanted into gnotobiotic mice. The combination of Malawian diet and kwashiorkor microbiome produced marked weight loss in recipient mice, accompanied by perturbations in amino acid, carbohydrate, and intermediary metabolism that were only transiently ameliorated with RUTF. These findings implicate the gut microbiome as a causal factor in kwashiorkor.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3667500/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3667500/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, Michelle I -- Yatsunenko, Tanya -- Manary, Mark J -- Trehan, Indi -- Mkakosya, Rajhab -- Cheng, Jiye -- Kau, Andrew L -- Rich, Stephen S -- Concannon, Patrick -- Mychaleckyj, Josyf C -- Liu, Jie -- Houpt, Eric -- Li, Jia V -- Holmes, Elaine -- Nicholson, Jeremy -- Knights, Dan -- Ursell, Luke K -- Knight, Rob -- Gordon, Jeffrey I -- DK078669/DK/NIDDK NIH HHS/ -- DK30292/DK/NIDDK NIH HHS/ -- F32 DK091044/DK/NIDDK NIH HHS/ -- P01 DK078669/DK/NIDDK NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- R37 DK030292/DK/NIDDK NIH HHS/ -- T32 HD049338/HD/NICHD NIH HHS/ -- T32-HD049338/HD/NICHD NIH HHS/ -- T35 DK074375/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2013 Feb 1;339(6119):548-54. doi: 10.1126/science.1229000.

    Beschreibung: Nerves are a common feature of the microenvironment, but their role in tumor growth and progression remains unclear. We found that the formation of autonomic nerve fibers in the prostate gland regulates prostate cancer development and dissemination in mouse models. The early phases of tumor development were prevented by chemical or surgical sympathectomy and by genetic deletion of stromal beta2- and beta3-adrenergic receptors. Tumors were also infiltrated by parasympathetic cholinergic fibers that promoted cancer dissemination. Cholinergic-induced tumor invasion and metastasis were inhibited by pharmacological blockade or genetic disruption of the stromal type 1 muscarinic receptor, leading to improved survival of the mice. A retrospective blinded analysis of prostate adenocarcinoma specimens from 43 patients revealed that the densities of sympathetic and parasympathetic nerve fibers in tumor and surrounding normal tissue, respectively, were associated with poor clinical outcomes. These findings may lead to novel therapeutic approaches for prostate cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Magnon, Claire -- Hall, Simon J -- Lin, Juan -- Xue, Xiaonan -- Gerber, Leah -- Freedland, Stephen J -- Frenette, Paul S -- DK056638/DK/NIDDK NIH HHS/ -- HL069438/HL/NHLBI NIH HHS/ -- HL097819/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2013 Jul 12;341(6142):1236361. doi: 10.1126/science.1236361.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ruth L. and David S.

    Beschreibung: The central nervous system rapidly learns that particular stimuli predict imminent danger. This learning is thought to involve associations between neutral and harmful stimuli in cortical and limbic brain regions, though associative neuroplasticity in sensory structures is increasingly appreciated. We observed the synaptic output of olfactory sensory neurons (OSNs) in individual mice before and after they learned that a particular odor indicated an impending foot shock. OSNs are the first cells in the olfactory system, physically contacting the odor molecules in the nose and projecting their axons to the brain's olfactory bulb. OSN output evoked by the shock-predictive odor was selectively facilitated after fear conditioning. These results indicate that affective information about a stimulus can be encoded in its very earliest representation in the nervous system.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4011636/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4011636/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kass, Marley D -- Rosenthal, Michelle C -- Pottackal, Joseph -- McGann, John P -- DC009442/DC/NIDCD NIH HHS/ -- DC013090/DC/NIDCD NIH HHS/ -- MH101293/MH/NIMH NIH HHS/ -- R00 DC009442/DC/NIDCD NIH HHS/ -- R01 DC013090/DC/NIDCD NIH HHS/ -- R01 MH101293/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2013 Dec 13;342(6164):1389-92. doi: 10.1126/science.1244916.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Behavioral and Systems Neuroscience Section, Department of Psychology, Rutgers, The State University of New Jersey, 152 Frelinghuysen Road, Piscataway, NJ 08854, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24337299" target="_blank"〉PubMed〈/a〉

    Beschreibung: The conservation of sleep across all animal species suggests that sleep serves a vital function. We here report that sleep has a critical function in ensuring metabolic homeostasis. Using real-time assessments of tetramethylammonium diffusion and two-photon imaging in live mice, we show that natural sleep or anesthesia are associated with a 60% increase in the interstitial space, resulting in a striking increase in convective exchange of cerebrospinal fluid with interstitial fluid. In turn, convective fluxes of interstitial fluid increased the rate of beta-amyloid clearance during sleep. Thus, the restorative function of sleep may be a consequence of the enhanced removal of potentially neurotoxic waste products that accumulate in the awake central nervous system.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3880190/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3880190/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xie, Lulu -- Kang, Hongyi -- Xu, Qiwu -- Chen, Michael J -- Liao, Yonghong -- Thiyagarajan, Meenakshisundaram -- O'Donnell, John -- Christensen, Daniel J -- Nicholson, Charles -- Iliff, Jeffrey J -- Takano, Takahiro -- Deane, Rashid -- Nedergaard, Maiken -- NS028642/NS/NINDS NIH HHS/ -- NS078167/NS/NINDS NIH HHS/ -- NS078304/NS/NINDS NIH HHS/ -- R01 DE022743/DE/NIDCR NIH HHS/ -- R01 NS075177/NS/NINDS NIH HHS/ -- R01 NS078167/NS/NINDS NIH HHS/ -- R01 NS078304/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2013 Oct 18;342(6156):373-7. doi: 10.1126/science.1241224.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Glial Disease and Therapeutics, Center for Translational Neuromedicine, Department of Neurosurgery, University of Rochester Medical Center, Rochester, NY 14642, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24136970" target="_blank"〉PubMed〈/a〉

    Beschreibung: We used single-cell genomic approaches to map DNA copy number variation (CNV) in neurons obtained from human induced pluripotent stem cell (hiPSC) lines and postmortem human brains. We identified aneuploid neurons, as well as numerous subchromosomal CNVs in euploid neurons. Neurotypic hiPSC-derived neurons had larger CNVs than fibroblasts, and several large deletions were found in hiPSC-derived neurons but not in matched neural progenitor cells. Single-cell sequencing of endogenous human frontal cortex neurons revealed that 13 to 41% of neurons have at least one megabase-scale de novo CNV, that deletions are twice as common as duplications, and that a subset of neurons have highly aberrant genomes marked by multiple alterations. Our results show that mosaic CNV is abundant in human neurons.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3975283/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3975283/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McConnell, Michael J -- Lindberg, Michael R -- Brennand, Kristen J -- Piper, Julia C -- Voet, Thierry -- Cowing-Zitron, Chris -- Shumilina, Svetlana -- Lasken, Roger S -- Vermeesch, Joris R -- Hall, Ira M -- Gage, Fred H -- DP2 OD006493/OD/NIH HHS/ -- DP20D006493-01/DP/NCCDPHP CDC HHS/ -- HHSN2752009000011C/PHS HHS/ -- N01-HD-9-011/HD/NICHD NIH HHS/ -- R01 MH095741/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2013 Nov 1;342(6158):632-7. doi: 10.1126/science.1243472.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, Salk Institute for Biological Studies, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24179226" target="_blank"〉PubMed〈/a〉

    Beschreibung: Increased fear memory generalization is associated with posttraumatic stress disorder, but the circuit mechanisms that regulate memory specificity remain unclear. Here, we define a neural circuit-composed of the medial prefrontal cortex, the nucleus reuniens (NR), and the hippocampus-that controls fear memory generalization. Inactivation of prefrontal inputs into the NR or direct silencing of NR projections enhanced fear memory generalization, whereas constitutive activation of NR neurons decreased memory generalization. Direct optogenetic activation of phasic and tonic action-potential firing of NR neurons during memory acquisition enhanced or reduced memory generalization, respectively. We propose that the NR determines the specificity and generalization of memory attributes for a particular context by processing information from the medial prefrontal cortex en route to the hippocampus.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3651700/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3651700/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Wei -- Sudhof, Thomas C -- K99 MH099153/MH/NIMH NIH HHS/ -- NS077906/NS/NINDS NIH HHS/ -- P50 MH086403/MH/NIMH NIH HHS/ -- R01 NS077906/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Mar 15;339(6125):1290-5. doi: 10.1126/science.1229534.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Physiology and Howard Hughes Medical Institute, Stanford University, Stanford, CA 94304-5453, USA. weixu@stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23493706" target="_blank"〉PubMed〈/a〉

    Beschreibung: CD8(+) T cell responses focus on a small fraction of pathogen- or vaccine-encoded peptides, and for some pathogens, these restricted recognition hierarchies limit the effectiveness of antipathogen immunity. We found that simian immunodeficiency virus (SIV) protein-expressing rhesus cytomegalovirus (RhCMV) vectors elicit SIV-specific CD8(+) T cells that recognize unusual, diverse, and highly promiscuous epitopes, including dominant responses to epitopes restricted by class II major histocompatibility complex (MHC) molecules. Induction of canonical SIV epitope-specific CD8(+) T cell responses is suppressed by the RhCMV-encoded Rh189 gene (corresponding to human CMV US11), and the promiscuous MHC class I- and class II-restricted CD8(+) T cell responses occur only in the absence of the Rh157.5, Rh157.4, and Rh157.6 (human CMV UL128, UL130, and UL131) genes. Thus, CMV vectors can be genetically programmed to achieve distinct patterns of CD8(+) T cell epitope recognition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3816976/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3816976/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hansen, Scott G -- Sacha, Jonah B -- Hughes, Colette M -- Ford, Julia C -- Burwitz, Benjamin J -- Scholz, Isabel -- Gilbride, Roxanne M -- Lewis, Matthew S -- Gilliam, Awbrey N -- Ventura, Abigail B -- Malouli, Daniel -- Xu, Guangwu -- Richards, Rebecca -- Whizin, Nathan -- Reed, Jason S -- Hammond, Katherine B -- Fischer, Miranda -- Turner, John M -- Legasse, Alfred W -- Axthelm, Michael K -- Edlefsen, Paul T -- Nelson, Jay A -- Lifson, Jeffrey D -- Fruh, Klaus -- Picker, Louis J -- P01 AI094417/AI/NIAID NIH HHS/ -- P51 OD 011092/OD/NIH HHS/ -- R01 AI059457/AI/NIAID NIH HHS/ -- R01 AI060392/AI/NIAID NIH HHS/ -- U24 OD010850/OD/NIH HHS/ -- New York, N.Y. -- Science. 2013 May 24;340(6135):1237874. doi: 10.1126/science.1237874.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vaccine and Gene Therapy Institute and Oregon National Primate Research Center, Oregon Health & Science University, Beaverton, OR 97006, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23704576" target="_blank"〉PubMed〈/a〉

    Beschreibung: Visual imagery during sleep has long been a topic of persistent speculation, but its private nature has hampered objective analysis. Here we present a neural decoding approach in which machine-learning models predict the contents of visual imagery during the sleep-onset period, given measured brain activity, by discovering links between human functional magnetic resonance imaging patterns and verbal reports with the assistance of lexical and image databases. Decoding models trained on stimulus-induced brain activity in visual cortical areas showed accurate classification, detection, and identification of contents. Our findings demonstrate that specific visual experience during sleep is represented by brain activity patterns shared by stimulus perception, providing a means to uncover subjective contents of dreaming using objective neural measurement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Horikawa, T -- Tamaki, M -- Miyawaki, Y -- Kamitani, Y -- New York, N.Y. -- Science. 2013 May 3;340(6132):639-42. doi: 10.1126/science.1234330.

    Beschreibung: Developmental gene expression is defined through cross-talk between the function of transcription factors and epigenetic status, including histone modification. Although several transcription factors play crucial roles in mammalian sex determination, how epigenetic regulation contributes to this process remains unknown. We observed male-to-female sex reversal in mice lacking the H3K9 demethylase Jmjd1a and found that Jmjd1a regulates expression of the mammalian Y chromosome sex-determining gene Sry. Jmjd1a directly and positively controls Sry expression by regulating H3K9me2 marks. These studies reveal a pivotal role of histone demethylation in mammalian sex determination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuroki, Shunsuke -- Matoba, Shogo -- Akiyoshi, Mika -- Matsumura, Yasuko -- Miyachi, Hitoshi -- Mise, Nathan -- Abe, Kuniya -- Ogura, Atsuo -- Wilhelm, Dagmar -- Koopman, Peter -- Nozaki, Masami -- Kanai, Yoshiakira -- Shinkai, Yoichi -- Tachibana, Makoto -- New York, N.Y. -- Science. 2013 Sep 6;341(6150):1106-9. doi: 10.1126/science.1239864.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Experimental Research Center for Infectious Diseases, Institute for Virus Research, Kyoto University, 53 Shogoin, Kawara-cho, Sakyo-ku, Kyoto, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24009392" target="_blank"〉PubMed〈/a〉

    Beschreibung: The hippocampal cognitive map is thought to be driven by distal visual cues and self-motion cues. However, other sensory cues also influence place cells. Hence, we measured rat hippocampal activity in virtual reality (VR), where only distal visual and nonvestibular self-motion cues provided spatial information, and in the real world (RW). In VR, place cells showed robust spatial selectivity; however, only 20% were track active, compared with 45% in the RW. This indicates that distal visual and nonvestibular self-motion cues are sufficient to provide selectivity, but vestibular and other sensory cues present in RW are necessary to fully activate the place-cell population. In addition, bidirectional cells preferentially encoded distance along the track in VR, while encoding absolute position in RW. Taken together, these results suggest the differential contributions of these sensory cues in shaping the hippocampal population code. Theta frequency was reduced, and its speed dependence was abolished in VR, but phase precession was unaffected, constraining mechanisms governing both hippocampal theta oscillations and temporal coding. These results reveal cooperative and competitive interactions between sensory cues for control over hippocampal spatiotemporal selectivity and theta rhythm.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4049564/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4049564/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ravassard, Pascal -- Kees, Ashley -- Willers, Bernard -- Ho, David -- Aharoni, Daniel -- Cushman, Jesse -- Aghajan, Zahra M -- Mehta, Mayank R -- 5R01MH092925-02/MH/NIMH NIH HHS/ -- R01 MH092925/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2013 Jun 14;340(6138):1342-6. doi: 10.1126/science.1232655.

    Beschreibung: The landmark HIV Prevention Trials Network (HPTN) 052 trial in HIV-discordant couples demonstrated unequivocally that treatment with antiretroviral therapy (ART) substantially lowers the probability of HIV transmission to the HIV-uninfected partner. However, it has been vigorously debated whether substantial population-level reductions in the rate of new HIV infections could be achieved in "real-world" sub-Saharan African settings where stable, cohabiting couples are often not the norm and where considerable operational challenges exist to the successful and sustainable delivery of treatment and care to large numbers of patients. We used data from one of Africa's largest population-based prospective cohort studies (in rural KwaZulu-Natal, South Africa) to follow up a total of 16,667 individuals who were HIV-uninfected at baseline, observing individual HIV seroconversions over the period 2004 to 2011. Holding other key HIV risk factors constant, individual HIV acquisition risk declined significantly with increasing ART coverage in the surrounding local community. For example, an HIV-uninfected individual living in a community with high ART coverage (30 to 40% of all HIV-infected individuals on ART) was 38% less likely to acquire HIV than someone living in a community where ART coverage was low (〈10% of all HIV-infected individuals on ART).〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4255272/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4255272/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanser, Frank -- Barnighausen, Till -- Grapsa, Erofili -- Zaidi, Jaffer -- Newell, Marie-Louise -- 082384/Z/07/Z/Wellcome Trust/United Kingdom -- 097410/Wellcome Trust/United Kingdom -- 1R01-HD058482-01/HD/NICHD NIH HHS/ -- R01 HD058482/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2013 Feb 22;339(6122):966-71. doi: 10.1126/science.1228160.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Africa Centre for Health and Population Studies, University of KwaZulu-Natal, South Africa. tanserf@africacentre.ac.za〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23430656" target="_blank"〉PubMed〈/a〉

    Beschreibung: During persistent viral infections, chronic immune activation, negative immune regulator expression, an elevated interferon signature, and lymphoid tissue destruction correlate with disease progression. We demonstrated that blockade of type I interferon (IFN-I) signaling using an IFN-I receptor neutralizing antibody reduced immune system activation, decreased expression of negative immune regulatory molecules, and restored lymphoid architecture in mice persistently infected with lymphocytic choriomeningitis virus. IFN-I blockade before and after establishment of persistent virus infection resulted in enhanced virus clearance and was CD4 T cell-dependent. Hence, we demonstrate a direct causal link between IFN-I signaling, immune activation, negative immune regulator expression, lymphoid tissue disorganization, and virus persistence. Our results suggest that therapies targeting IFN-I may help control persistent virus infections.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3640797/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3640797/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Teijaro, John R -- Ng, Cherie -- Lee, Andrew M -- Sullivan, Brian M -- Sheehan, Kathleen C F -- Welch, Megan -- Schreiber, Robert D -- de la Torre, Juan Carlos -- Oldstone, Michael B A -- AI007354/AI/NIAID NIH HHS/ -- AI047140/AI/NIAID NIH HHS/ -- AI077719/AI/NIAID NIH HHS/ -- AI09484/AI/NIAID NIH HHS/ -- CA43059/CA/NCI NIH HHS/ -- HL007195/HL/NHLBI NIH HHS/ -- NS041219/NS/NINDS NIH HHS/ -- R01 AI009484/AI/NIAID NIH HHS/ -- R01 AI047140/AI/NIAID NIH HHS/ -- R01 AI077719/AI/NIAID NIH HHS/ -- U54 AI057160/AI/NIAID NIH HHS/ -- U54AI057160/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Apr 12;340(6129):207-11. doi: 10.1126/science.1235214.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology and Microbial Science, The Scripps Research Institute, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23580529" target="_blank"〉PubMed〈/a〉

    Beschreibung: The data reported in the Technical Comments by Fitz et al., Price et al., Tesseur et al., and Veeraraghavalu et al. replicate and validate our central conclusion that bexarotene stimulates the clearance of soluble beta-amyloid peptides and results in the reversal of behavioral deficits in mouse models of Alzheimer's disease (AD). The basis of the inability to reproduce the drug-stimulated microglial-mediated reduction in plaque burden is unexplained. However, we concluded that plaque burden is functionally unrelated to improved cognition and memory elicited by bexarotene.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3714602/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3714602/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Landreth, Gary E -- Cramer, Paige E -- Lakner, Mitchell M -- Cirrito, John R -- Wesson, Daniel W -- Brunden, Kurt R -- Wilson, Donald A -- AG030482-03S1/AG/NIA NIH HHS/ -- DC003906/DC/NIDCD NIH HHS/ -- K01 AG029524/AG/NIA NIH HHS/ -- P50-AG005681/AG/NIA NIH HHS/ -- R01 AG037693/AG/NIA NIH HHS/ -- R01 DC003906/DC/NIDCD NIH HHS/ -- R01-AG037693/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2013 May 24;340(6135):924-g. doi: 10.1126/science.1234114.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Alzheimer Research Laboratory, Department of Neurosciences, Case Western Reserve University School of Medicine, Cleveland, OH 44106, USA. gel2@case.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23704556" target="_blank"〉PubMed〈/a〉

    Beschreibung: The scale-up of antiretroviral therapy (ART) is expected to raise adult life expectancy in populations with high HIV prevalence. Using data from a population cohort of over 101,000 individuals in rural KwaZulu-Natal, South Africa, we measured changes in adult life expectancy for 2000-2011. In 2003, the year before ART became available in the public-sector health system, adult life expectancy was 49.2 years; by 2011, adult life expectancy had increased to 60.5 years--an 11.3-year gain. Based on standard monetary valuation of life, the survival benefits of ART far outweigh the costs of providing treatment in this community. These gains in adult life expectancy signify the social value of ART and have implications for the investment decisions of individuals, governments, and donors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3860268/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3860268/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bor, Jacob -- Herbst, Abraham J -- Newell, Marie-Louise -- Barnighausen, Till -- 097410/Wellcome Trust/United Kingdom -- 1R01MH083539-01/MH/NIMH NIH HHS/ -- R01 HD058482-01/HD/NICHD NIH HHS/ -- R01 MH083539/MH/NIMH NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2013 Feb 22;339(6122):961-5. doi: 10.1126/science.1230413.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Africa Centre for Health and Population Studies, University of KwaZulu-Natal, Post Office Box 198, Mtubatuba, KwaZulu-Natal 3935, South Africa. jbor@hsph.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23430655" target="_blank"〉PubMed〈/a〉
