Beschreibung: The neuromuscular junction (NMJ) is the synapse between a motor neuron and skeletal muscle. Defects in NMJ transmission cause muscle weakness, termed myasthenia. The muscle protein Dok-7 is essential for activation of the receptor kinase MuSK, which governs NMJ formation, and DOK7 mutations underlie familial limb-girdle myasthenia (DOK7 myasthenia), a neuromuscular disease characterized by small NMJs. Here, we show in a mouse model of DOK7 myasthenia that therapeutic administration of an adeno-associated virus (AAV) vector encoding the human DOK7 gene resulted in an enlargement of NMJs and substantial increases in muscle strength and life span. When applied to model mice of another neuromuscular disorder, autosomal dominant Emery-Dreifuss muscular dystrophy, DOK7 gene therapy likewise resulted in enlargement of NMJs as well as positive effects on motor activity and life span. These results suggest that therapies aimed at enlarging the NMJ may be useful for a range of neuromuscular disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arimura, Sumimasa -- Okada, Takashi -- Tezuka, Tohru -- Chiyo, Tomoko -- Kasahara, Yuko -- Yoshimura, Toshiro -- Motomura, Masakatsu -- Yoshida, Nobuaki -- Beeson, David -- Takeda, Shin'ichi -- Yamanashi, Yuji -- G0701521/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Sep 19;345(6203):1505-8. doi: 10.1126/science.1250744.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Genetics, The Institute of Medical Science, The University of Tokyo, Tokyo, Japan. ; Department of Molecular Therapy, National Institute of Neuroscience, National Center of Neurology and Psychiatry, Tokyo, Japan. ; Department of Occupational Therapy, Nagasaki University School of Health Sciences, Nagasaki, Japan. ; Department of Electrical and Electronics Engineering, Faculty of Engineering, Nagasaki Institute of Applied Science, Nagasaki, Japan. ; Laboratory of Developmental Genetics, The Institute of Medical Science, The University of Tokyo, Tokyo, Japan. ; Neurosciences Group, Weatherall Institute of Molecular Medicine, University of Oxford, Oxford, UK. ; Division of Genetics, The Institute of Medical Science, The University of Tokyo, Tokyo, Japan. yyamanas@ims.u-tokyo.ac.jp.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25237101" target="_blank"〉PubMed〈/a〉

Beschreibung: After an infection, pathogen-specific tissue-resident memory T cells (T(RM) cells) persist in nonlymphoid tissues to provide rapid control upon reinfection, and vaccination strategies that create T(RM) cell pools at sites of pathogen entry are therefore attractive. However, it is not well understood how T(RM) cells provide such pathogen protection. Here, we demonstrate that activated T(RM) cells in mouse skin profoundly alter the local tissue environment by inducing a number of broadly active antiviral and antibacterial genes. This "pathogen alert" allows skin T(RM) cells to protect against an antigenically unrelated virus. These data describe a mechanism by which tissue-resident memory CD8(+) T cells protect previously infected sites that is rapid, amplifies the activation of a small number of cells into an organ-wide response, and has the capacity to control escape variants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ariotti, Silvia -- Hogenbirk, Marc A -- Dijkgraaf, Feline E -- Visser, Lindy L -- Hoekstra, Mirjam E -- Song, Ji-Ying -- Jacobs, Heinz -- Haanen, John B -- Schumacher, Ton N -- New York, N.Y. -- Science. 2014 Oct 3;346(6205):101-5. doi: 10.1126/science.1254803.

Beschreibung: Birds are the most species-rich class of tetrapod vertebrates and have wide relevance across many research fields. We explored bird macroevolution using full genomes from 48 avian species representing all major extant clades. The avian genome is principally characterized by its constrained size, which predominantly arose because of lineage-specific erosion of repetitive elements, large segmental deletions, and gene loss. Avian genomes furthermore show a remarkably high degree of evolutionary stasis at the levels of nucleotide sequence, gene synteny, and chromosomal structure. Despite this pattern of conservation, we detected many non-neutral evolutionary changes in protein-coding genes and noncoding regions. These analyses reveal that pan-avian genomic diversity covaries with adaptations to different lifestyles and convergent evolution of traits.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4390078/" 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/PMC4390078/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Guojie -- Li, Cai -- Li, Qiye -- Li, Bo -- Larkin, Denis M -- Lee, Chul -- Storz, Jay F -- Antunes, Agostinho -- Greenwold, Matthew J -- Meredith, Robert W -- Odeen, Anders -- Cui, Jie -- Zhou, Qi -- Xu, Luohao -- Pan, Hailin -- Wang, Zongji -- Jin, Lijun -- Zhang, Pei -- Hu, Haofu -- Yang, Wei -- Hu, Jiang -- Xiao, Jin -- Yang, Zhikai -- Liu, Yang -- Xie, Qiaolin -- Yu, Hao -- Lian, Jinmin -- Wen, Ping -- Zhang, Fang -- Li, Hui -- Zeng, Yongli -- Xiong, Zijun -- Liu, Shiping -- Zhou, Long -- Huang, Zhiyong -- An, Na -- Wang, Jie -- Zheng, Qiumei -- Xiong, Yingqi -- Wang, Guangbiao -- Wang, Bo -- Wang, Jingjing -- Fan, Yu -- da Fonseca, Rute R -- Alfaro-Nunez, Alonzo -- Schubert, Mikkel -- Orlando, Ludovic -- Mourier, Tobias -- Howard, Jason T -- Ganapathy, Ganeshkumar -- Pfenning, Andreas -- Whitney, Osceola -- Rivas, Miriam V -- Hara, Erina -- Smith, Julia -- Farre, Marta -- Narayan, Jitendra -- Slavov, Gancho -- Romanov, Michael N -- Borges, Rui -- Machado, Joao Paulo -- Khan, Imran -- Springer, Mark S -- Gatesy, John -- Hoffmann, Federico G -- Opazo, Juan C -- Hastad, Olle -- Sawyer, Roger H -- Kim, Heebal -- Kim, Kyu-Won -- Kim, Hyeon Jeong -- Cho, Seoae -- Li, Ning -- Huang, Yinhua -- Bruford, Michael W -- Zhan, Xiangjiang -- Dixon, Andrew -- Bertelsen, Mads F -- Derryberry, Elizabeth -- Warren, Wesley -- Wilson, Richard K -- Li, Shengbin -- Ray, David A -- Green, Richard E -- O'Brien, Stephen J -- Griffin, Darren -- Johnson, Warren E -- Haussler, David -- Ryder, Oliver A -- Willerslev, Eske -- Graves, Gary R -- Alstrom, Per -- Fjeldsa, Jon -- Mindell, David P -- Edwards, Scott V -- Braun, Edward L -- Rahbek, Carsten -- Burt, David W -- Houde, Peter -- Zhang, Yong -- Yang, Huanming -- Wang, Jian -- Avian Genome Consortium -- Jarvis, Erich D -- Gilbert, M Thomas P -- Wang, Jun -- DP1 OD000448/OD/NIH HHS/ -- DP1OD000448/OD/NIH HHS/ -- R01 HL087216/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1311-20. doi: 10.1126/science.1251385.

Beschreibung: DNA double-strand breaks (DSBs) are introduced in meiosis to initiate recombination and generate crossovers, the reciprocal exchanges of genetic material between parental chromosomes. Here, we present high-resolution maps of meiotic DSBs in individual human genomes. Comparing DSB maps between individuals shows that along with DNA binding by PRDM9, additional factors may dictate the efficiency of DSB formation. We find evidence for both GC-biased gene conversion and mutagenesis around meiotic DSB hotspots, while frequent colocalization of DSB hotspots with chromosome rearrangement breakpoints implicates the aberrant repair of meiotic DSBs in genomic disorders. Furthermore, our data indicate that DSB frequency is a major determinant of crossover rate. These maps provide new insights into the regulation of meiotic recombination and the impact of meiotic recombination on genome function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pratto, Florencia -- Brick, Kevin -- Khil, Pavel -- Smagulova, Fatima -- Petukhova, Galina V -- Camerini-Otero, R Daniel -- 1R01GM084104-01A1/GM/NIGMS NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2014 Nov 14;346(6211):1256442. doi: 10.1126/science.1256442.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Diabetes, Digestive and Kidney Diseases, NIH, Bethesda, MD, USA. ; Department of Biochemistry and Molecular Biology, Uniformed Services University of Health Sciences, Bethesda, MD, USA. ; Department of Biochemistry and Molecular Biology, Uniformed Services University of Health Sciences, Bethesda, MD, USA. rdcamerini@mail.nih.gov galina.petukhova@usuhs.edu. ; National Institute of Diabetes, Digestive and Kidney Diseases, NIH, Bethesda, MD, USA. rdcamerini@mail.nih.gov galina.petukhova@usuhs.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25395542" target="_blank"〉PubMed〈/a〉

Beschreibung: Parabiosis experiments indicate that impaired regeneration in aged mice is reversible by exposure to a young circulation, suggesting that young blood contains humoral "rejuvenating" factors that can restore regenerative function. Here, we demonstrate that the circulating protein growth differentiation factor 11 (GDF11) is a rejuvenating factor for skeletal muscle. Supplementation of systemic GDF11 levels, which normally decline with age, by heterochronic parabiosis or systemic delivery of recombinant protein, reversed functional impairments and restored genomic integrity in aged muscle stem cells (satellite cells). Increased GDF11 levels in aged mice also improved muscle structural and functional features and increased strength and endurance exercise capacity. These data indicate that GDF11 systemically regulates muscle aging and may be therapeutically useful for reversing age-related skeletal muscle and stem cell dysfunction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4104429/" 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/PMC4104429/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sinha, Manisha -- Jang, Young C -- Oh, Juhyun -- Khong, Danika -- Wu, Elizabeth Y -- Manohar, Rohan -- Miller, Christine -- Regalado, Samuel G -- Loffredo, Francesco S -- Pancoast, James R -- Hirshman, Michael F -- Lebowitz, Jessica -- Shadrach, Jennifer L -- Cerletti, Massimiliano -- Kim, Mi-Jeong -- Serwold, Thomas -- Goodyear, Laurie J -- Rosner, Bernard -- Lee, Richard T -- Wagers, Amy J -- 1DP2 OD004345/OD/NIH HHS/ -- 1R01 AG033053/AG/NIA NIH HHS/ -- 1R01 AG040019/AG/NIA NIH HHS/ -- 5U01 HL100402/HL/NHLBI NIH HHS/ -- DP2 OD004345/OD/NIH HHS/ -- P30 AG038072/AG/NIA NIH HHS/ -- R01 AG032977/AG/NIA NIH HHS/ -- R01 AG033053/AG/NIA NIH HHS/ -- R01 AG040019/AG/NIA NIH HHS/ -- R01 AR042238/AR/NIAMS NIH HHS/ -- R01 AR42238/AR/NIAMS NIH HHS/ -- T32 DE007057/DE/NIDCR NIH HHS/ -- U01 HL100402/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 May 9;344(6184):649-52. doi: 10.1126/science.1251152.

Beschreibung: Comparative genomic analyses have revealed that genes may arise from ancestrally nongenic sequence. However, the origin and spread of these de novo genes within populations remain obscure. We identified 142 segregating and 106 fixed testis-expressed de novo genes in a population sample of Drosophila melanogaster. These genes appear to derive primarily from ancestral intergenic, unexpressed open reading frames, with natural selection playing a significant role in their spread. These results reveal a heretofore unappreciated dynamism of gene content.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4391638/" 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/PMC4391638/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Li -- Saelao, Perot -- Jones, Corbin D -- Begun, David J -- GM084056/GM/NIGMS NIH HHS/ -- R01 GM084056/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Feb 14;343(6172):769-72. doi: 10.1126/science.1248286.

Beschreibung: Most land animals normally walk forward but switch to backward walking upon sensing an obstacle or danger in the path ahead. A change in walking direction is likely to be triggered by descending "command" neurons from the brain that act upon local motor circuits to alter the timing of leg muscle activation. Here we identify descending neurons for backward walking in Drosophila--the MDN neurons. MDN activity is required for flies to walk backward when they encounter an impassable barrier and is sufficient to trigger backward walking under conditions in which flies would otherwise walk forward. We also identify ascending neurons, MAN, that promote persistent backward walking, possibly by inhibiting forward walking. These findings provide an initial glimpse into the circuits and logic that control walking direction in Drosophila.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bidaye, Salil S -- Machacek, Christian -- Wu, Yang -- Dickson, Barry J -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):97-101. doi: 10.1126/science.1249964.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Institute of Molecular Pathology (IMP), Dr. Bohrgasse 7, A-1030 Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24700860" target="_blank"〉PubMed〈/a〉

Beschreibung: How we attend to objects and their features that cannot be separated by location is not understood. We presented two temporally and spatially overlapping streams of objects, faces versus houses, and used magnetoencephalography and functional magnetic resonance imaging to separate neuronal responses to attended and unattended objects. Attention to faces versus houses enhanced the sensory responses in the fusiform face area (FFA) and parahippocampal place area (PPA), respectively. The increases in sensory responses were accompanied by induced gamma synchrony between the inferior frontal junction, IFJ, and either FFA or PPA, depending on which object was attended. The IFJ appeared to be the driver of the synchrony, as gamma phases were advanced by 20 ms in IFJ compared to FFA or PPA. Thus, the IFJ may direct the flow of visual processing during object-based attention, at least in part through coupled oscillations with specialized areas such as FFA and PPA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baldauf, Daniel -- Desimone, Robert -- P30EY2621/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):424-7. doi: 10.1126/science.1247003.

Beschreibung: Reef-building in metazoans represents an important ecological innovation whereby individuals collectively enhance feeding efficiency and gain protection from competitors and predation. The appearance of metazoan reefs in the fossil record therefore indicates an adaptive response to complex ecological pressures. In the Nama Group, Namibia, we found evidence of reef-building by the earliest known skeletal metazoan, the globally distributed Cloudina, ~548 million years ago. These Cloudina reefs formed open frameworks without a microbial component but with mutual attachment and cementation between individuals. Orientated growth implies a passive suspension-feeding habit into nutrient-rich currents. The characteristics of Cloudina support the view that metazoan reef-building was promoted by the rise of substrate competitors and predators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Penny, A M -- Wood, R -- Curtis, A -- Bowyer, F -- Tostevin, R -- Hoffman, K-H -- New York, N.Y. -- Science. 2014 Jun 27;344(6191):1504-6. doi: 10.1126/science.1253393.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of GeoSciences, University of Edinburgh, West Mains Road, Edinburgh EH9 3JW, UK. a.m.penny@ed.ac.uk. ; School of GeoSciences, University of Edinburgh, West Mains Road, Edinburgh EH9 3JW, UK. ; Department of Earth Sciences, University College London, Gower Street, London WC1E 6BT, UK. ; Geological Survey of Namibia, Private Bag 13297, Windhoek, Namibia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24970084" target="_blank"〉PubMed〈/a〉

Beschreibung: Reported trends in the mean and variability of coastal upwelling in eastern boundary currents have raised concerns about the future of these highly productive and biodiverse marine ecosystems. However, the instrumental records on which these estimates are based are insufficiently long to determine whether such trends exceed preindustrial limits. In the California Current, a 576-year reconstruction of climate variables associated with winter upwelling indicates that variability increased over the latter 20th century to levels equaled only twice during the past 600 years. This modern trend in variance may be unique, because it appears to be driven by an unprecedented succession of extreme, downwelling-favorable, winter climate conditions that profoundly reduce productivity for marine predators of commercial and conservation interest.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Black, Bryan A -- Sydeman, William J -- Frank, David C -- Griffin, Daniel -- Stahle, David W -- Garcia-Reyes, Marisol -- Rykaczewski, Ryan R -- Bograd, Steven J -- Peterson, William T -- New York, N.Y. -- Science. 2014 Sep 19;345(6203):1498-502. doi: 10.1126/science.1253209.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Texas Marine Science Institute, 750 Channel View Drive, Port Aransas, TX 78373, USA. bryan.black@utexas.edu. ; Farallon Institute for Advanced Ecosystem Research, 101 H Street, Suite Q, Petaluma, CA 94952, USA. ; Swiss Federal Research Institute WSL, Zurcherstrasse 111, CH-8903 Birmensdorf, Switzerland and Oeschger Centre for Climate Change Research, University of Bern, Zahringerstrasse 25, CH-3012 Bern, Switzerland. ; Department of Geology and Geophysics, Woods Hole Oceanographic Institution, 266 Woods Hole Road, Woods Hole, MA 02543, USA. ; Department of Geosciences, University of Arkansas, 216 Ozark Hall, Fayetteville, AR 72701, USA. ; Department of Biological Sciences and Marine Science Program, University of South Carolina, 701 Sumter Street, Columbia, SC 29208, USA. ; Environmental Research Division, Southwest Fisheries Science Center, National Oceanic and Atmospheric Administration (NOAA), 1352 Lighthouse Avenue, Pacific Grove, CA 93950, USA. ; Northwest Fisheries Science Center, Hatfield Marine Science Center, NOAA, 2030 Southeast Marine Science Drive, Newport, OR 97365, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25237100" target="_blank"〉PubMed〈/a〉

Beschreibung: Sex-specific chromosomes, like the W of most female birds and the Y of male mammals, usually have lost most genes owing to a lack of recombination. We analyze newly available genomes of 17 bird species representing the avian phylogenetic range, and find that more than half of them do not have as fully degenerated W chromosomes as that of chicken. We show that avian sex chromosomes harbor tremendous diversity among species in their composition of pseudoautosomal regions and degree of Z/W differentiation. Punctuated events of shared or lineage-specific recombination suppression have produced a gradient of "evolutionary strata" along the Z chromosome, which initiates from the putative avian sex-determining gene DMRT1 and ends at the pseudoautosomal region. W-linked genes are subject to ongoing functional decay after recombination was suppressed, and the tempo of degeneration slows down in older strata. Overall, we unveil a complex history of avian sex chromosome evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Qi -- Zhang, Jilin -- Bachtrog, Doris -- An, Na -- Huang, Quanfei -- Jarvis, Erich D -- Gilbert, M Thomas P -- Zhang, Guojie -- GM076007/GM/NIGMS NIH HHS/ -- GM093182/GM/NIGMS NIH HHS/ -- R01 GM076007/GM/NIGMS NIH HHS/ -- R01 GM093182/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1246338. doi: 10.1126/science.1246338.

Beschreibung: How sleep helps learning and memory remains unknown. We report in mouse motor cortex that sleep after motor learning promotes the formation of postsynaptic dendritic spines on a subset of branches of individual layer V pyramidal neurons. New spines are formed on different sets of dendritic branches in response to different learning tasks and are protected from being eliminated when multiple tasks are learned. Neurons activated during learning of a motor task are reactivated during subsequent non-rapid eye movement sleep, and disrupting this neuronal reactivation prevents branch-specific spine formation. These findings indicate that sleep has a key role in promoting learning-dependent synapse formation and maintenance on selected dendritic branches, which contribute to memory storage.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4447313/" 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/PMC4447313/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Guang -- Lai, Cora Sau Wan -- Cichon, Joseph -- Ma, Lei -- Li, Wei -- Gan, Wen-Biao -- P01 NS074972/NS/NINDS NIH HHS/ -- R01 NS047325/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2014 Jun 6;344(6188):1173-8. doi: 10.1126/science.1249098.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Skirball Institute, Department of Neuroscience and Physiology, New York University School of Medicine, New York, NY 10016, USA.

Beschreibung: Myelin-forming oligodendrocytes (OLs) are formed continuously in the healthy adult brain. In this work, we study the function of these late-forming cells and the myelin they produce. Learning a new motor skill (such as juggling) alters the structure of the brain's white matter, which contains many OLs, suggesting that late-born OLs might contribute to motor learning. Consistent with this idea, we show that production of newly formed OLs is briefly accelerated in mice that learn a new skill (running on a "complex wheel" with irregularly spaced rungs). By genetically manipulating the transcription factor myelin regulatory factor in OL precursors, we blocked production of new OLs during adulthood without affecting preexisting OLs or myelin. This prevented the mice from mastering the complex wheel. Thus, generation of new OLs and myelin is important for learning motor skills.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McKenzie, Ian A -- Ohayon, David -- Li, Huiliang -- de Faria, Joana Paes -- Emery, Ben -- Tohyama, Koujiro -- Richardson, William D -- 100269/Wellcome Trust/United Kingdom -- G0800575/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Oct 17;346(6207):318-22. doi: 10.1126/science.1254960.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Wolfson Institute for Biomedical Research, University College London, Gower Street, London WC1E 6BT, UK. ; Department of Anatomy and Neuroscience and the Florey Institute for Neuroscience and Mental Health, University of Melbourne, Melbourne, Victoria 3010, Australia. ; The Center for Electron Microscopy and Bio-Imaging Research, Iwate Medical University, 19-1 Uchimuru, Morioka, Iwate 020-8505, Japan. ; The Wolfson Institute for Biomedical Research, University College London, Gower Street, London WC1E 6BT, UK. w.richardson@ucl.ac.uk.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25324381" target="_blank"〉PubMed〈/a〉

Beschreibung: Environmental exposures affect gamete function and fertility, but the mechanisms are poorly understood. Here, we show that pheromones sensed by ciliated neurons in the Caenorhabditis elegans nose alter the lipid microenvironment within the oviduct, thereby affecting sperm motility. In favorable environments, pheromone-responsive sensory neurons secrete a transforming growth factor-beta ligand called DAF-7, which acts as a neuroendocrine factor that stimulates prostaglandin-endoperoxide synthase [cyclooxygenase (Cox)]-independent prostaglandin synthesis in the ovary. Oocytes secrete F-class prostaglandins that guide sperm toward them. These prostaglandins are also synthesized in Cox knockout mice, raising the possibility that similar mechanisms exist in other animals. Our data indicate that environmental cues perceived by the female nervous system affect sperm function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4094289/" 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/PMC4094289/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McKnight, Katherine -- Hoang, Hieu D -- Prasain, Jeevan K -- Brown, Naoko -- Vibbert, Jack -- Hollister, Kyle A -- Moore, Ray -- Ragains, Justin R -- Reese, Jeff -- Miller, Michael A -- GM085105/GM/NIGMS NIH HHS/ -- HL096967/HL/NHLBI NIH HHS/ -- HL109199/HL/NHLBI NIH HHS/ -- HL110950/HL/NHLBI NIH HHS/ -- HL114439/HL/NHLBI NIH HHS/ -- P30 AR050948/AR/NIAMS NIH HHS/ -- P30 DK079337/DK/NIDDK NIH HHS/ -- P40 OD010440/OD/NIH HHS/ -- R01 GM085105/GM/NIGMS NIH HHS/ -- R01 HL096967/HL/NHLBI NIH HHS/ -- R01 HL109199/HL/NHLBI NIH HHS/ -- S10 RR19261/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2014 May 16;344(6185):754-7. doi: 10.1126/science.1250598.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Reproductive Endocrinology and Infertility, Department of Obstetrics and Gynecology, University of Alabama at Birmingham, Birmingham, AL 35294, USA. ; Department of Cell, Developmental and Integrative Biology, University of Alabama at Birmingham, Birmingham, AL 35294, USA. ; Department of Pharmacology and Toxicology, University of Alabama at Birmingham, Birmingham, AL 35294, USA. ; Department of Pediatrics, Vanderbilt University, Nashville, TN 37232, USA. ; Department of Chemistry, Louisiana State University, Baton Rouge, LA 70803, USA. ; Department of Pediatrics, Vanderbilt University, Nashville, TN 37232, USA.

Beschreibung: Immune and inflammatory responses require leukocytes to migrate within and through the vasculature, a process that is facilitated by their capacity to switch to a polarized morphology with an asymmetric distribution of receptors. We report that neutrophil polarization within activated venules served to organize a protruding domain that engaged activated platelets present in the bloodstream. The selectin ligand PSGL-1 transduced signals emanating from these interactions, resulting in the redistribution of receptors that drive neutrophil migration. Consequently, neutrophils unable to polarize or to transduce signals through PSGL-1 displayed aberrant crawling, and blockade of this domain protected mice against thromboinflammatory injury. These results reveal that recruited neutrophils scan for activated platelets, and they suggest that the neutrophils' bipolarity allows the integration of signals present at both the endothelium and the circulation before inflammation proceeds.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4280847/" 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/PMC4280847/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sreeramkumar, Vinatha -- Adrover, Jose M -- Ballesteros, Ivan -- Cuartero, Maria Isabel -- Rossaint, Jan -- Bilbao, Izaskun -- Nacher, Maria -- Pitaval, Christophe -- Radovanovic, Irena -- Fukui, Yoshinori -- McEver, Rodger P -- Filippi, Marie-Dominique -- Lizasoain, Ignacio -- Ruiz-Cabello, Jesus -- Zarbock, Alexander -- Moro, Maria A -- Hidalgo, Andres -- HL03463/HL/NHLBI NIH HHS/ -- HL085607/HL/NHLBI NIH HHS/ -- HL090676/HL/NHLBI NIH HHS/ -- P01 HL085607/HL/NHLBI NIH HHS/ -- R01 HL034363/HL/NHLBI NIH HHS/ -- R01 HL090676/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 5;346(6214):1234-8. doi: 10.1126/science.1256478.

Beschreibung: In 1990, Andrew Bakun proposed that increasing greenhouse gas concentrations would force intensification of upwelling-favorable winds in eastern boundary current systems that contribute substantial services to society. Because there is considerable disagreement about whether contemporary wind trends support Bakun's hypothesis, we performed a meta-analysis of the literature on upwelling-favorable wind intensification. The preponderance of published analyses suggests that winds have intensified in the California, Benguela, and Humboldt upwelling systems and weakened in the Iberian system over time scales ranging up to 60 years; wind change is equivocal in the Canary system. Stronger intensification signals are observed at higher latitudes, consistent with the warming pattern associated with climate change. Overall, reported changes in coastal winds, although subtle and spatially variable, support Bakun's hypothesis of upwelling intensification in eastern boundary current systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sydeman, W J -- Garcia-Reyes, M -- Schoeman, D S -- Rykaczewski, R R -- Thompson, S A -- Black, B A -- Bograd, S J -- New York, N.Y. -- Science. 2014 Jul 4;345(6192):77-80. doi: 10.1126/science.1251635.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Farallon Institute for Advanced Ecosystem Research, Suite Q, 101 H Street, Petaluma, CA 94952, USA. wsydeman@comcast.net. ; Farallon Institute for Advanced Ecosystem Research, Suite Q, 101 H Street, Petaluma, CA 94952, USA. ; Faculty of Science, Health, Education and Engineering, University of the Sunshine Coast, Locked Bag 4, Maroochydore DC, Queensland 4558, Australia. ; Department of Biological Sciences and Marine Science Program, University of South Carolina, 701 Sumter Street, Columbia, SC 29208, USA. ; Farallon Institute for Advanced Ecosystem Research, Suite Q, 101 H Street, Petaluma, CA 94952, USA.

Beschreibung: Cross-cultural psychologists have mostly contrasted East Asia with the West. However, this study shows that there are major psychological differences within China. We propose that a history of farming rice makes cultures more interdependent, whereas farming wheat makes cultures more independent, and these agricultural legacies continue to affect people in the modern world. We tested 1162 Han Chinese participants in six sites and found that rice-growing southern China is more interdependent and holistic-thinking than the wheat-growing north. To control for confounds like climate, we tested people from neighboring counties along the rice-wheat border and found differences that were just as large. We also find that modernization and pathogen prevalence theories do not fit the data.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Talhelm, T -- Zhang, X -- Oishi, S -- Shimin, C -- Duan, D -- Lan, X -- Kitayama, S -- New York, N.Y. -- Science. 2014 May 9;344(6184):603-8. doi: 10.1126/science.1246850.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Virginia, Charlottesville, VA 22904, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24812395" target="_blank"〉PubMed〈/a〉

Beschreibung: Parental care, including feeding and protection of young, is essential for the survival as well as mental and physical well-being of the offspring. A large variety of parental behaviors has been described across species and sexes, raising fascinating questions about how animals identify the young and how brain circuits drive and modulate parental displays in males and females. Recent studies have begun to uncover a striking antagonistic interplay between brain systems underlying parental care and infant-directed aggression in both males and females, as well as a large range of intrinsic and environmentally driven neural modulation and plasticity. Improved understanding of the neural control of parental interactions in animals should provide novel insights into the complex issue of human parental care in both health and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4230532/" 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/PMC4230532/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dulac, Catherine -- O'Connell, Lauren A -- Wu, Zheng -- R01 DC009019/DC/NIDCD NIH HHS/ -- R01 DC013087/DC/NIDCD NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Aug 15;345(6198):765-70. doi: 10.1126/science.1253291.

Beschreibung: In theoretical ecology, traditional studies based on dynamical stability and numerical simulations have not found a unified answer to the effect of network architecture on community persistence. Here, we introduce a mathematical framework based on the concept of structural stability to explain such a disparity of results. We investigated the range of conditions necessary for the stable coexistence of all species in mutualistic systems. We show that the apparently contradictory conclusions reached by previous studies arise as a consequence of overseeing either the necessary conditions for persistence or its dependence on model parameterization. We show that observed network architectures maximize the range of conditions for species coexistence. We discuss the applicability of structural stability to study other types of interspecific interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rohr, Rudolf P -- Saavedra, Serguei -- Bascompte, Jordi -- New York, N.Y. -- Science. 2014 Jul 25;345(6195):1253497. doi: 10.1126/science.1253497.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Integrative Ecology Group, Estacion Biologica de Donana-Consejo Superior de Investigaciones Cientificas (EBD-CSIC), Calle Americo Vespucio s/n, E-41092 Sevilla, Spain.

Beschreibung: Humans can discriminate several million different colors and almost half a million different tones, but the number of discriminable olfactory stimuli remains unknown. The lay and scientific literature typically claims that humans can discriminate 10,000 odors, but this number has never been empirically validated. We determined the resolution of the human sense of smell by testing the capacity of humans to discriminate odor mixtures with varying numbers of shared components. On the basis of the results of psychophysical testing, we calculated that humans can discriminate at least 1 trillion olfactory stimuli. This is far more than previous estimates of distinguishable olfactory stimuli. It demonstrates that the human olfactory system, with its hundreds of different olfactory receptors, far outperforms the other senses in the number of physically different stimuli it can discriminate.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4483192/" 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/PMC4483192/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bushdid, C -- Magnasco, M O -- Vosshall, L B -- Keller, A -- UL1 TR000043/TR/NCATS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Mar 21;343(6177):1370-2. doi: 10.1126/science.1249168.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Neurogenetics and Behavior, The Rockefeller University, 1230 York Avenue, Box 63, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24653035" target="_blank"〉PubMed〈/a〉

Beschreibung: We demonstrate a technique for mapping brain activity that combines molecular specificity and spatial coverage using a neurotransmitter sensor detectable by magnetic resonance imaging (MRI). This molecular functional MRI (fMRI) method yielded time-resolved volumetric measurements of dopamine release evoked by reward-related lateral hypothalamic brain stimulation of rats injected with the neurotransmitter sensor. Peak dopamine concentrations and release rates were observed in the anterior nucleus accumbens core. Substantial dopamine transients were also present in more caudal areas. Dopamine-release amplitudes correlated with the rostrocaudal stimulation coordinate, suggesting participation of hypothalamic circuitry in modulating dopamine responses. This work provides a foundation for development and application of quantitative molecular fMRI techniques targeted toward numerous components of neural physiology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Taekwan -- Cai, Lili X -- Lelyveld, Victor S -- Hai, Aviad -- Jasanoff, Alan -- DP2-OD002114/OD/NIH HHS/ -- R01-DA02899/DA/NIDA NIH HHS/ -- R01-NS076462/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2014 May 2;344(6183):533-5. doi: 10.1126/science.1249380.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Engineering, Massachusetts Institute of Technology (MIT), Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24786083" target="_blank"〉PubMed〈/a〉

Beschreibung: Heterosexual transmission of HIV-1 typically results in one genetic variant establishing systemic infection. We compared, for 137 linked transmission pairs, the amino acid sequences encoded by non-envelope genes of viruses in both partners and demonstrate a selection bias for transmission of residues that are predicted to confer increased in vivo fitness on viruses in the newly infected, immunologically naive recipient. Although tempered by transmission risk factors, such as donor viral load, genital inflammation, and recipient gender, this selection bias provides an overall transmission advantage for viral quasispecies that are dominated by viruses with high in vivo fitness. Thus, preventative or therapeutic approaches that even marginally reduce viral fitness may lower the overall transmission rates and offer long-term benefits even upon successful transmission.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4289910/" 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/PMC4289910/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carlson, Jonathan M -- Schaefer, Malinda -- Monaco, Daniela C -- Batorsky, Rebecca -- Claiborne, Daniel T -- Prince, Jessica -- Deymier, Martin J -- Ende, Zachary S -- Klatt, Nichole R -- DeZiel, Charles E -- Lin, Tien-Ho -- Peng, Jian -- Seese, Aaron M -- Shapiro, Roger -- Frater, John -- Ndung'u, Thumbi -- Tang, Jianming -- Goepfert, Paul -- Gilmour, Jill -- Price, Matt A -- Kilembe, William -- Heckerman, David -- Goulder, Philip J R -- Allen, Todd M -- Allen, Susan -- Hunter, Eric -- 2P51RR000165-51/RR/NCRR NIH HHS/ -- G108/626/Medical Research Council/United Kingdom -- OD P51OD11132/OD/NIH HHS/ -- P01-AI074415/AI/NIAID NIH HHS/ -- P30 AI050409/AI/NIAID NIH HHS/ -- P51 OD010425/OD/NIH HHS/ -- P51 OD011132/OD/NIH HHS/ -- P51RR165/RR/NCRR NIH HHS/ -- R01 AI064060/AI/NIAID NIH HHS/ -- R01 AI64060/AI/NIAID NIH HHS/ -- R37 AI051231/AI/NIAID NIH HHS/ -- R37 AI51231/AI/NIAID NIH HHS/ -- T32 AI007387/AI/NIAID NIH HHS/ -- T32-AI007387/AI/NIAID NIH HHS/ -- U01 AI 66454/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Jul 11;345(6193):1254031. doi: 10.1126/science.1254031.

Beschreibung: A major evolutionary transition to eusociality with reproductive division of labor between queens and workers has arisen independently at least 10 times in the ants, bees, and wasps. Pheromones produced by queens are thought to play a key role in regulating this complex social system, but their evolutionary history remains unknown. Here, we identify the first sterility-inducing queen pheromones in a wasp, bumblebee, and desert ant and synthesize existing data on compounds that characterize female fecundity in 64 species of social insects. Our results show that queen pheromones are strikingly conserved across at least three independent origins of eusociality, with wasps, ants, and some bees all appearing to use nonvolatile, saturated hydrocarbons to advertise fecundity and/or suppress worker reproduction. These results suggest that queen pheromones evolved from conserved signals of solitary ancestors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van Oystaeyen, Annette -- Oliveira, Ricardo Caliari -- Holman, Luke -- van Zweden, Jelle S -- Romero, Carmen -- Oi, Cintia A -- d'Ettorre, Patrizia -- Khalesi, Mohammadreza -- Billen, Johan -- Wackers, Felix -- Millar, Jocelyn G -- Wenseleers, Tom -- New York, N.Y. -- Science. 2014 Jan 17;343(6168):287-90. doi: 10.1126/science.1244899.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Socioecology and Social Evolution, Zoological Institute, University of Leuven, Naamsestraat 59-Box 2466, 3000 Leuven, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24436417" target="_blank"〉PubMed〈/a〉

Beschreibung: It is not just a manner of speaking: "Mind reading," or working out what others are thinking and feeling, is markedly similar to print reading. Both of these distinctly human skills recover meaning from signs, depend on dedicated cortical areas, are subject to genetically heritable disorders, show cultural variation around a universal core, and regulate how people behave. But when it comes to development, the evidence is conflicting. Some studies show that, like learning to read print, learning to read minds is a long, hard process that depends on tuition. Others indicate that even very young, nonliterate infants are already capable of mind reading. Here, we propose a resolution to this conflict. We suggest that infants are equipped with neurocognitive mechanisms that yield accurate expectations about behavior ("automatic" or "implicit" mind reading), whereas "explicit" mind reading, like literacy, is a culturally inherited skill; it is passed from one generation to the next by verbal instruction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heyes, Cecilia M -- Frith, Chris D -- 091593/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Jun 20;344(6190):1243091. doi: 10.1126/science.1243091.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉All Souls College and Department of Experimental Psychology, University of Oxford, Oxford OX1 4AL, UK. cecilia.heyes@all-souls.ox.ac.uk. ; Wellcome Trust Centre for Neuroimaging, University College London, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24948740" target="_blank"〉PubMed〈/a〉

Beschreibung: Mutations in the mitochondrial genome are associated with multiple diseases and biological processes; however, little is known about the extent of sequence variation in the mitochondrial transcriptome. By ultra-deeply sequencing mitochondrial RNA (〉6000x) from the whole blood of ~1000 individuals from the CARTaGENE project, we identified remarkable levels of sequence variation within and across individuals, as well as sites that show consistent patterns of posttranscriptional modification. Using a genome-wide association study, we find that posttranscriptional modification of functionally important sites in mitochondrial transfer RNAs (tRNAs) is under strong genetic control, largely driven by a missense mutation in MRPP3 that explains ~22% of the variance. These results reveal a major nuclear genetic determinant of posttranscriptional modification in mitochondria and suggest that tRNA posttranscriptional modification may affect cellular energy production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hodgkinson, Alan -- Idaghdour, Youssef -- Gbeha, Elias -- Grenier, Jean-Christophe -- Hip-Ki, Elodie -- Bruat, Vanessa -- Goulet, Jean-Philippe -- de Malliard, Thibault -- Awadalla, Philip -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):413-5. doi: 10.1126/science.1251110.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CHU Sainte-Justine Research Centre, Department of Pediatrics, Faculty of Medicine, Universite de Montreal, 3175 Chemin de la Cote-Sainte-Catherine, Montreal, Quebec H3T 1C5, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24763589" target="_blank"〉PubMed〈/a〉

Beschreibung: The science of morality has drawn heavily on well-controlled but artificial laboratory settings. To study everyday morality, we repeatedly assessed moral or immoral acts and experiences in a large (N = 1252) sample using ecological momentary assessment. Moral experiences were surprisingly frequent and manifold. Liberals and conservatives emphasized somewhat different moral dimensions. Religious and nonreligious participants did not differ in the likelihood or quality of committed moral and immoral acts. Being the target of moral or immoral deeds had the strongest impact on happiness, whereas committing moral or immoral deeds had the strongest impact on sense of purpose. Analyses of daily dynamics revealed evidence for both moral contagion and moral licensing. In sum, morality science may benefit from a closer look at the antecedents, dynamics, and consequences of everyday moral experience.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hofmann, Wilhelm -- Wisneski, Daniel C -- Brandt, Mark J -- Skitka, Linda J -- New York, N.Y. -- Science. 2014 Sep 12;345(6202):1340-3. doi: 10.1126/science.1251560.

Beschreibung: To systematically investigate the impact of immune stimulation upon regulatory variant activity, we exposed primary monocytes from 432 healthy Europeans to interferon-gamma (IFN-gamma) or differing durations of lipopolysaccharide and mapped expression quantitative trait loci (eQTLs). More than half of cis-eQTLs identified, involving hundreds of genes and associated pathways, are detected specifically in stimulated monocytes. Induced innate immune activity reveals multiple master regulatory trans-eQTLs including the major histocompatibility complex (MHC), coding variants altering enzyme and receptor function, an IFN-beta cytokine network showing temporal specificity, and an interferon regulatory factor 2 (IRF2) transcription factor-modulated network. Induced eQTL are significantly enriched for genome-wide association study loci, identifying context-specific associations to putative causal genes including CARD9, ATM, and IRF8. Thus, applying pathophysiologically relevant immune stimuli assists resolution of functional genetic variants.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4064786/" 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/PMC4064786/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fairfax, Benjamin P -- Humburg, Peter -- Makino, Seiko -- Naranbhai, Vivek -- Wong, Daniel -- Lau, Evelyn -- Jostins, Luke -- Plant, Katharine -- Andrews, Robert -- McGee, Chris -- Knight, Julian C -- 074318/Wellcome Trust/United Kingdom -- 088891/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 281824/European Research Council/International -- 98082/Medical Research Council/United Kingdom -- G1001708/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1246949. doi: 10.1126/science.1246949.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Centre for Human Genetics, University of Oxford, Roosevelt Drive, Oxford OX3 7BN, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604202" target="_blank"〉PubMed〈/a〉

Beschreibung: Little is known about how human genetic variation affects the responses to environmental stimuli in the context of complex diseases. Experimental and computational approaches were applied to determine the effects of genetic variation on the induction of pathogen-responsive genes in human dendritic cells. We identified 121 common genetic variants associated in cis with variation in expression responses to Escherichia coli lipopolysaccharide, influenza, or interferon-beta (IFN-beta). We localized and validated causal variants to binding sites of pathogen-activated STAT (signal transducer and activator of transcription) and IRF (IFN-regulatory factor) transcription factors. We also identified a common variant in IRF7 that is associated in trans with type I IFN induction in response to influenza infection. Our results reveal common alleles that explain interindividual variation in pathogen sensing and provide functional annotation for genetic variants that alter susceptibility to inflammatory diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4124741/" 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/PMC4124741/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Mark N -- Ye, Chun -- Villani, Alexandra-Chloe -- Raj, Towfique -- Li, Weibo -- Eisenhaure, Thomas M -- Imboywa, Selina H -- Chipendo, Portia I -- Ran, F Ann -- Slowikowski, Kamil -- Ward, Lucas D -- Raddassi, Khadir -- McCabe, Cristin -- Lee, Michelle H -- Frohlich, Irene Y -- Hafler, David A -- Kellis, Manolis -- Raychaudhuri, Soumya -- Zhang, Feng -- Stranger, Barbara E -- Benoist, Christophe O -- De Jager, Philip L -- Regev, Aviv -- Hacohen, Nir -- DP1 CA174427/CA/NCI NIH HHS/ -- DP1 MH100706/DP/NCCDPHP CDC HHS/ -- DP1 MH100706/MH/NIMH NIH HHS/ -- DP2 OD002230/OD/NIH HHS/ -- F32 AG043267/AG/NIA NIH HHS/ -- P30 DK043351/DK/NIDDK NIH HHS/ -- P50 HG006193/HG/NHGRI NIH HHS/ -- R01 AI091568/AI/NIAID NIH HHS/ -- R01 AR063759/AR/NIAMS NIH HHS/ -- R01 DK097768/DK/NIDDK NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- RC2 GM093080/GM/NIGMS NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- T32 HG002295/HG/NHGRI NIH HHS/ -- U19 AI082630/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1246980. doi: 10.1126/science.1246980.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute of Massachusetts Institute of Technology (MIT) and Harvard, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604203" target="_blank"〉PubMed〈/a〉

Beschreibung: Parenting behaviors, such as the provisioning of food by parents to offspring, are known to be highly responsive to changes in environment. However, we currently know little about how such flexibility affects the ways in which parenting is adapted and evolves in response to environmental variation. This is because few studies quantify how individuals vary in their response to changing environments, especially social environments created by other individuals with which parents interact. Social environmental factors differ from nonsocial factors, such as food availability, because parents and offspring both contribute and respond to the social environment they experience. This interdependence leads to the coevolution of flexible behaviors involved in parenting, which could, paradoxically, constrain the ability of individuals to rapidly adapt to changes in their nonsocial environment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Royle, Nick J -- Russell, Andrew F -- Wilson, Alastair J -- BB/G022976/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Aug 15;345(6198):776-81. doi: 10.1126/science.1253294.

Beschreibung: Pregnenolone is considered the inactive precursor of all steroid hormones, and its potential functional effects have been largely uninvestigated. The administration of the main active principle of Cannabis sativa (marijuana), Delta(9)-tetrahydrocannabinol (THC), substantially increases the synthesis of pregnenolone in the brain via activation of the type-1 cannabinoid (CB1) receptor. Pregnenolone then, acting as a signaling-specific inhibitor of the CB1 receptor, reduces several effects of THC. This negative feedback mediated by pregnenolone reveals a previously unknown paracrine/autocrine loop protecting the brain from CB1 receptor overactivation that could open an unforeseen approach for the treatment of cannabis intoxication and addiction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4057431/" 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/PMC4057431/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vallee, Monique -- Vitiello, Sergio -- Bellocchio, Luigi -- Hebert-Chatelain, Etienne -- Monlezun, Stephanie -- Martin-Garcia, Elena -- Kasanetz, Fernando -- Baillie, Gemma L -- Panin, Francesca -- Cathala, Adeline -- Roullot-Lacarriere, Valerie -- Fabre, Sandy -- Hurst, Dow P -- Lynch, Diane L -- Shore, Derek M -- Deroche-Gamonet, Veronique -- Spampinato, Umberto -- Revest, Jean-Michel -- Maldonado, Rafael -- Reggio, Patricia H -- Ross, Ruth A -- Marsicano, Giovanni -- Piazza, Pier Vincenzo -- 260515/European Research Council/International -- DA-003934/DA/NIDA NIH HHS/ -- DA-03672/DA/NIDA NIH HHS/ -- DA-09789/DA/NIDA NIH HHS/ -- K05 DA021358/DA/NIDA NIH HHS/ -- R01 DA003934/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2014 Jan 3;343(6166):94-8. doi: 10.1126/science.1243985.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM, Neurocentre Magendie, Physiopathologie de la Plasticite Neuronale, U862, F-33000 Bordeaux, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24385629" target="_blank"〉PubMed〈/a〉

Beschreibung: In many metazoans, germ cells are separated from somatic lineages early in development and maintain their identity throughout life. Here, we show that a Polycomb group (PcG) component, Enhancer of Zeste [E(z)], a histone transferase that generates trimethylation at lysine 27 of histone H3, maintains germline identity in Drosophila adult testes. We find excessive early-stage somatic gonadal cells in E(z) mutant testes, which originate from both overproliferative cyst stem cells and germ cells turning on an early-stage somatic cell marker. Using complementary lineage-tracing experiments in E(z) mutant testes, a portion of excessive early-stage somatic gonadal cells are found to originate from early-stage germ cells, including germline stem cells. Moreover, knocking down E(z) specifically in somatic cells caused this change, which suggests a non-cell autonomous role of E(z) to antagonize somatic identity in germ cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4040133/" 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/PMC4040133/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eun, Suk Ho -- Shi, Zhen -- Cui, Kairong -- Zhao, Keji -- Chen, Xin -- R00 HD055052/HD/NICHD NIH HHS/ -- R00HD055052/HD/NICHD NIH HHS/ -- R01 HD065816/HD/NICHD NIH HHS/ -- R01HD065816/HD/NICHD NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2014 Mar 28;343(6178):1513-6. doi: 10.1126/science.1246514.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, The Johns Hopkins University, Baltimore, MD 21218, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24675960" target="_blank"〉PubMed〈/a〉

Beschreibung: High-quality early childhood programs have been shown to have substantial benefits in reducing crime, raising earnings, and promoting education. Much less is known about their benefits for adult health. We report on the long-term health effects of one of the oldest and most heavily cited early childhood interventions with long-term follow-up evaluated by the method of randomization: the Carolina Abecedarian Project (ABC). Using recently collected biomedical data, we find that disadvantaged children randomly assigned to treatment have significantly lower prevalence of risk factors for cardiovascular and metabolic diseases in their mid-30s. The evidence is especially strong for males. The mean systolic blood pressure among the control males is 143 millimeters of mercury (mm Hg), whereas it is only 126 mm Hg among the treated. One in four males in the control group is affected by metabolic syndrome, whereas none in the treatment group are affected. To reach these conclusions, we address several statistical challenges. We use exact permutation tests to account for small sample sizes and conduct a parallel bootstrap confidence interval analysis to confirm the permutation analysis. We adjust inference to account for the multiple hypotheses tested and for nonrandom attrition. Our evidence shows the potential of early life interventions for preventing disease and promoting health.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4028126/" 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/PMC4028126/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Campbell, Frances -- Conti, Gabriella -- Heckman, James J -- Moon, Seong Hyeok -- Pinto, Rodrigo -- Pungello, Elizabeth -- Pan, Yi -- 1R01HD54702/HD/NICHD NIH HHS/ -- 5R37HD065072/HD/NICHD NIH HHS/ -- 5RC1MD004344/MD/NIMHD NIH HHS/ -- R37 HD065072/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2014 Mar 28;343(6178):1478-85. doi: 10.1126/science.1248429.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Frank Porter Graham Child Development Institute, University of North Carolina, Chapel Hill, NC 27599, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24675955" target="_blank"〉PubMed〈/a〉

Beschreibung: Avian brood parasites lay eggs in the nests of other birds, which raise the unrelated chicks and typically suffer partial or complete loss of their own brood. However, carrion crows Corvus corone corone can benefit from parasitism by the great spotted cuckoo Clamator glandarius. Parasitized nests have lower rates of predation-induced failure due to production of a repellent secretion by cuckoo chicks, but among nests that are successful, those with cuckoo chicks fledge fewer crows. The outcome of these counterbalancing effects fluctuates between parasitism and mutualism each season, depending on the intensity of predation pressure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Canestrari, Daniela -- Bolopo, Diana -- Turlings, Ted C J -- Roder, Gregory -- Marcos, Jose M -- Baglione, Vittorio -- New York, N.Y. -- Science. 2014 Mar 21;343(6177):1350-2. doi: 10.1126/science.1249008.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology of Organisms and Systems, University of Oviedo, Oviedo, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24653032" target="_blank"〉PubMed〈/a〉

Beschreibung: The current view of motor learning suggests that when we revisit a task, the brain recalls the motor commands it previously learned. In this view, motor memory is a memory of motor commands, acquired through trial-and-error and reinforcement. Here we show that the brain controls how much it is willing to learn from the current error through a principled mechanism that depends on the history of past errors. This suggests that the brain stores a previously unknown form of memory, a memory of errors. A mathematical formulation of this idea provides insights into a host of puzzling experimental data, including savings and meta-learning, demonstrating that when we are better at a motor task, it is partly because the brain recognizes the errors it experienced before.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4506639/" 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/PMC4506639/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herzfeld, David J -- Vaswani, Pavan A -- Marko, Mollie K -- Shadmehr, Reza -- 1F31NS079121/NS/NINDS NIH HHS/ -- F31 NS090860/NS/NINDS NIH HHS/ -- R01 NS078311/NS/NINDS NIH HHS/ -- R01NS078311/NS/NINDS NIH HHS/ -- T32 GM007309/GM/NIGMS NIH HHS/ -- T32EB003383/EB/NIBIB NIH HHS/ -- T32GM007057/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Sep 12;345(6202):1349-53. doi: 10.1126/science.1253138.

Beschreibung: Ecologists have long sought to understand the factors controlling the structure of savanna vegetation. Using data from 2154 sites in savannas across Africa, Australia, and South America, we found that increasing moisture availability drives increases in fire and tree basal area, whereas fire reduces tree basal area. However, among continents, the magnitude of these effects varied substantially, so that a single model cannot adequately represent savanna woody biomass across these regions. Historical and environmental differences drive the regional variation in the functional relationships between woody vegetation, fire, and climate. These same differences will determine the regional responses of vegetation to future climates, with implications for global carbon stocks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lehmann, Caroline E R -- Anderson, T Michael -- Sankaran, Mahesh -- Higgins, Steven I -- Archibald, Sally -- Hoffmann, William A -- Hanan, Niall P -- Williams, Richard J -- Fensham, Roderick J -- Felfili, Jeanine -- Hutley, Lindsay B -- Ratnam, Jayashree -- San Jose, Jose -- Montes, Ruben -- Franklin, Don -- Russell-Smith, Jeremy -- Ryan, Casey M -- Durigan, Giselda -- Hiernaux, Pierre -- Haidar, Ricardo -- Bowman, David M J S -- Bond, William J -- New York, N.Y. -- Science. 2014 Jan 31;343(6170):548-52. doi: 10.1126/science.1247355.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Macquarie University, New South Wales 2109, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24482480" target="_blank"〉PubMed〈/a〉

Beschreibung: This paper presents a new data infrastructure for measuring economic activity. The infrastructure records transactions and account balances, yielding measurements with scope and accuracy that have little precedent in economics. The data are drawn from a diverse population that overrepresents males and younger adults but contains large numbers of underrepresented groups. The data infrastructure permits evaluation of a benchmark theory in economics that predicts that individuals should use a combination of cash management, saving, and borrowing to make the timing of income irrelevant for the timing of spending. As in previous studies and in contrast to the predictions of the theory, there is a response of spending to the arrival of anticipated income. The data also show, however, that this apparent excess sensitivity of spending results largely from the coincident timing of regular income and regular spending. The remaining excess sensitivity is concentrated among individuals with less liquidity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gelman, Michael -- Kariv, Shachar -- Shapiro, Matthew D -- Silverman, Dan -- Tadelis, Steven -- P30 AG012839/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2014 Jul 11;345(6193):212-5. doi: 10.1126/science.1247727.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Economics, University of Michigan, Ann Arbor, MI 48109, USA. ; Department of Economics, University of California, Berkeley, Berkeley, CA 94720, USA. ; Department of Economics, University of Michigan, Ann Arbor, MI 48109, USA.

Beschreibung: A substantial literature shows that U.S. early childhood interventions have important long-term economic benefits. However, there is little evidence on this question for developing countries. We report substantial effects on the earnings of participants in a randomized intervention conducted in 1986-1987 that gave psychosocial stimulation to growth-stunted Jamaican toddlers. The intervention consisted of weekly visits from community health workers over a 2-year period that taught parenting skills and encouraged mothers and children to interact in ways that develop cognitive and socioemotional skills. The authors reinterviewed 105 out of 129 study participants 20 years later and found that the intervention increased earnings by 25%, enough for them to catch up to the earnings of a nonstunted comparison group identified at baseline (65 out of 84 participants).〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4574862/" 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/PMC4574862/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gertler, Paul -- Heckman, James -- Pinto, Rodrigo -- Zanolini, Arianna -- Vermeersch, Christel -- Walker, Susan -- Chang, Susan M -- Grantham-McGregor, Sally -- R01 HD054702/HD/NICHD NIH HHS/ -- R01HD54702/HD/NICHD NIH HHS/ -- R37 HD065072/HD/NICHD NIH HHS/ -- R37HD065072/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2014 May 30;344(6187):998-1001. doi: 10.1126/science.1251178.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of California Berkeley, Berkeley, CA, USA.

Beschreibung: Songbirds represent an important model organism for elucidating molecular mechanisms that link genes with complex behaviors, in part because they have discrete vocal learning circuits that have parallels with those that mediate human speech. We found that ~10% of the genes in the avian genome were regulated by singing, and we found a striking regional diversity of both basal and singing-induced programs in the four key song nuclei of the zebra finch, a vocal learning songbird. The region-enriched patterns were a result of distinct combinations of region-enriched transcription factors (TFs), their binding motifs, and presinging acetylation of histone 3 at lysine 27 (H3K27ac) enhancer activity in the regulatory regions of the associated genes. RNA interference manipulations validated the role of the calcium-response transcription factor (CaRF) in regulating genes preferentially expressed in specific song nuclei in response to singing. Thus, differential combinatorial binding of a small group of activity-regulated TFs and predefined epigenetic enhancer activity influences the anatomical diversity of behaviorally regulated gene networks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4359888/" 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/PMC4359888/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitney, Osceola -- Pfenning, Andreas R -- Howard, Jason T -- Blatti, Charles A -- Liu, Fang -- Ward, James M -- Wang, Rui -- Audet, Jean-Nicoles -- Kellis, Manolis -- Mukherjee, Sayan -- Sinha, Saurabh -- Hartemink, Alexander J -- West, Anne E -- Jarvis, Erich D -- 5T32MH018882-18/MH/NIMH NIH HHS/ -- R01 DC007218/DC/NIDCD NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01DC007218/DC/NIDCD NIH HHS/ -- R21 NS084336/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1256780. doi: 10.1126/science.1256780.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Howard Hughes Medical Institute, and Duke University Medical Center, Durham, NC 27710, USA. owhitney@gmail.com apfenning@csail.mit.edu west@neuro.duke.edu jarvis@neuro.duke.edu. ; Department of Neurobiology, Howard Hughes Medical Institute, and Duke University Medical Center, Durham, NC 27710, USA.

Beschreibung: Animal migrations span the globe, involving immense numbers of individuals from a wide range of taxa. Migrants transport nutrients, energy, and other organisms as they forage and are preyed upon throughout their journeys. These highly predictable, pulsed movements across large spatial scales render migration a potentially powerful yet underappreciated dimension of biodiversity that is intimately embedded within resident communities. We review examples from across the animal kingdom to distill fundamental processes by which migratory animals influence communities and ecosystems, demonstrating that they can uniquely alter energy flow, food-web topology and stability, trophic cascades, and the structure of metacommunities. Given the potential for migration to alter ecological networks worldwide, we suggest an integrative framework through which community dynamics and ecosystem functioning may explicitly consider animal migrations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bauer, S -- Hoye, B J -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):1242552. doi: 10.1126/science.1242552.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bird Migration, Swiss Ornithological Institute, 6204 Sempach, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24700862" target="_blank"〉PubMed〈/a〉

Beschreibung: In the adult central nervous system, the vasculature of the neurogenic niche regulates neural stem cell behavior by providing circulating and secreted factors. Age-related decline of neurogenesis and cognitive function is associated with reduced blood flow and decreased numbers of neural stem cells. Therefore, restoring the functionality of the niche should counteract some of the negative effects of aging. We show that factors found in young blood induce vascular remodeling, culminating in increased neurogenesis and improved olfactory discrimination in aging mice. Further, we show that GDF11 alone can improve the cerebral vasculature and enhance neurogenesis. The identification of factors that slow the age-dependent deterioration of the neurogenic niche in mice may constitute the basis for new methods of treating age-related neurodegenerative and neurovascular diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4123747/" 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/PMC4123747/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Katsimpardi, Lida -- Litterman, Nadia K -- Schein, Pamela A -- Miller, Christine M -- Loffredo, Francesco S -- Wojtkiewicz, Gregory R -- Chen, John W -- Lee, Richard T -- Wagers, Amy J -- Rubin, Lee L -- 1DP2 OD004345/OD/NIH HHS/ -- 1R01 AG033053/AG/NIA NIH HHS/ -- 1R01 AG040019/AG/NIA NIH HHS/ -- 5U01 HL100402/HL/NHLBI NIH HHS/ -- DP2 OD004345/OD/NIH HHS/ -- R01 AG032977/AG/NIA NIH HHS/ -- R01 AG033053/AG/NIA NIH HHS/ -- R01 AG040019/AG/NIA NIH HHS/ -- R01 NS070835/NS/NINDS NIH HHS/ -- R01 NS072167/NS/NINDS NIH HHS/ -- R01NS070835/NS/NINDS NIH HHS/ -- R01NS072167/NS/NINDS NIH HHS/ -- U01 HL100402/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 May 9;344(6184):630-4. doi: 10.1126/science.1251141.

Beschreibung: Most animals sleep more early in life than in adulthood, but the function of early sleep is not known. Using Drosophila, we found that increased sleep in young flies was associated with an elevated arousal threshold and resistance to sleep deprivation. Excess sleep results from decreased inhibition of a sleep-promoting region by a specific dopaminergic circuit. Experimental hyperactivation of this circuit in young flies results in sleep loss and lasting deficits in adult courtship behaviors. These deficits are accompanied by impaired development of a single olfactory glomerulus, VA1v, which normally displays extensive sleep-dependent growth after eclosion. Our results demonstrate that sleep promotes normal brain development that gives rise to an adult behavior critical for species propagation and suggest that rapidly growing regions of the brain are most susceptible to sleep perturbations early in life.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4479292/" 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/PMC4479292/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kayser, Matthew S -- Yue, Zhifeng -- Sehgal, Amita -- R25MH060490/MH/NIMH NIH HHS/ -- T32 HL007713/HL/NHLBI NIH HHS/ -- T32HL07713/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Apr 18;344(6181):269-74. doi: 10.1126/science.1250553.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24744368" target="_blank"〉PubMed〈/a〉
