    Pyogenic bacterial infections in humans with MyD88 deficiency (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2008-08-02
    Beschreibung: MyD88 is a key downstream adapter for most Toll-like receptors (TLRs) and interleukin-1 receptors (IL-1Rs). MyD88 deficiency in mice leads to susceptibility to a broad range of pathogens in experimental settings of infection. We describe a distinct situation in a natural setting of human infection. Nine children with autosomal recessive MyD88 deficiency suffered from life-threatening, often recurrent pyogenic bacterial infections, including invasive pneumococcal disease. However, these patients were otherwise healthy, with normal resistance to other microbes. Their clinical status improved with age, but not due to any cellular leakiness in MyD88 deficiency. The MyD88-dependent TLRs and IL-1Rs are therefore essential for protective immunity to a small number of pyogenic bacteria, but redundant for host defense to most natural infections.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2688396/" 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/PMC2688396/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉von Bernuth, Horst -- Picard, Capucine -- Jin, Zhongbo -- Pankla, Rungnapa -- Xiao, Hui -- Ku, Cheng-Lung -- Chrabieh, Maya -- Mustapha, Imen Ben -- Ghandil, Pegah -- Camcioglu, Yildiz -- Vasconcelos, Julia -- Sirvent, Nicolas -- Guedes, Margarida -- Vitor, Artur Bonito -- Herrero-Mata, Maria Jose -- Arostegui, Juan Ignacio -- Rodrigo, Carlos -- Alsina, Laia -- Ruiz-Ortiz, Estibaliz -- Juan, Manel -- Fortuny, Claudia -- Yague, Jordi -- Anton, Jordi -- Pascal, Mariona -- Chang, Huey-Hsuan -- Janniere, Lucile -- Rose, Yoann -- Garty, Ben-Zion -- Chapel, Helen -- Issekutz, Andrew -- Marodi, Laszlo -- Rodriguez-Gallego, Carlos -- Banchereau, Jacques -- Abel, Laurent -- Li, Xiaoxia -- Chaussabel, Damien -- Puel, Anne -- Casanova, Jean-Laurent -- U19 AI057234/AI/NIAID NIH HHS/ -- U19 AI057234-02/AI/NIAID NIH HHS/ -- U19 AIO57234-02/PHS HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Aug 1;321(5889):691-6. doi: 10.1126/science.1158298.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Genetics of Infectious Diseases, INSERM U550, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18669862" target="_blank"〉PubMed〈/a〉

    Wnt3a-mediated formation of phosphatidylinositol 4,5-bisphosphate regulates LRP6 phosphorylation (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2008-09-06
    Beschreibung: The canonical Wnt-beta-catenin signaling pathway is initiated by inducing phosphorylation of one of the Wnt receptors, low-density lipoprotein receptor-related protein 6 (LRP6), at threonine residue 1479 (Thr1479) and serine residue 1490 (Ser1490). By screening a human kinase small interfering RNA library, we identified phosphatidylinositol 4-kinase type II alpha and phosphatidylinositol-4-phosphate 5-kinase type I (PIP5KI) as required for Wnt3a-induced LRP6 phosphorylation at Ser1490 in mammalian cells and confirmed that these kinases are important for Wnt signaling in Xenopus embryos. Wnt3a stimulates the formation of phosphatidylinositol 4,5-bisphosphates [PtdIns (4,5)P2] through frizzled and dishevelled, the latter of which directly interacted with and activated PIP5KI. In turn, PtdIns (4,5)P2 regulated phosphorylation of LRP6 at Thr1479 and Ser1490. Therefore, our study reveals a signaling mechanism for Wnt to regulate LRP6 phosphorylation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2532521/" 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/PMC2532521/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pan, Weijun -- Choi, Sun-Cheol -- Wang, He -- Qin, Yuanbo -- Volpicelli-Daley, Laura -- Swan, Laura -- Lucast, Louise -- Khoo, Cynthia -- Zhang, Xiaowu -- Li, Lin -- Abrams, Charles S -- Sokol, Sergei Y -- Wu, Dianqing -- AR051476/AR/NIAMS NIH HHS/ -- CA132317/CA/NCI NIH HHS/ -- DA018343/DA/NIDA NIH HHS/ -- HL080706/HL/NHLBI NIH HHS/ -- NS36251/NS/NINDS NIH HHS/ -- P30 DA018343/DA/NIDA NIH HHS/ -- R01 AR051476/AR/NIAMS NIH HHS/ -- R01 AR051476-01A1/AR/NIAMS NIH HHS/ -- R01 AR051476-02/AR/NIAMS NIH HHS/ -- R01 AR051476-03/AR/NIAMS NIH HHS/ -- R01 CA132317/CA/NCI NIH HHS/ -- R01 CA132317-01A2/CA/NCI NIH HHS/ -- R01 CA139395/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 Sep 5;321(5894):1350-3. doi: 10.1126/science.1160741.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Yale University 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/18772438" target="_blank"〉PubMed〈/a〉

    Construction of synthetic immunogen: use of new T-helper epitope on malaria circumsporozoite protein (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-02-27
    Beschreibung: The circumsporozoite (CS) protein of Plasmodium falciparum is the focus of intense efforts to develop an antisporozoite malaria vaccine. Localization of sites for T-cell recognition on this molecule is critical for vaccine design. By using an algorithm designed to predict T-cell sites and a large panel of H-2 congenic mice, a major nonrepetitive T-cell site was located. When a synthetic peptide corresponding to this site was covalently linked to the major B-cell site on the molecule, an immunogen capable of eliciting a high-titer antibody response was formed. This peptide sequence could prime helper T cells for a secondary response to the intact CS protein. The new helper T-cell site is located outside the repetitive region of the CS protein and appears to be the immunodominant T site on the molecule. This approach should be useful in the rational design and construction of vaccines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Good, M F -- Maloy, W L -- Lunde, M N -- Margalit, H -- Cornette, J L -- Smith, G L -- Moss, B -- Miller, L H -- Berzofsky, J A -- New York, N.Y. -- Science. 1987 Feb 27;235(4792):1059-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2434994" target="_blank"〉PubMed〈/a〉

    An agonist of toll-like receptor 5 has radioprotective activity in mouse and primate models (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2008-04-12
    Beschreibung: The toxicity of ionizing radiation is associated with massive apoptosis in radiosensitive organs. Here, we investigate whether a drug that activates a signaling mechanism used by tumor cells to suppress apoptosis can protect healthy cells from the harmful effects of radiation. We studied CBLB502, a polypeptide drug derived from Salmonella flagellin that binds to Toll-like receptor 5 (TLR5) and activates nuclear factor-kappaB signaling. A single injection of CBLB502 before lethal total-body irradiation protected mice from both gastrointestinal and hematopoietic acute radiation syndromes and resulted in improved survival. CBLB502 injected after irradiation also enhanced survival, but at lower radiation doses. It is noteworthy that the drug did not decrease tumor radiosensitivity in mouse models. CBLB502 also showed radioprotective activity in lethally irradiated rhesus monkeys. Thus, TLR5 agonists could potentially improve the therapeutic index of cancer radiotherapy and serve as biological protectants in radiation emergencies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4322935/" 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/PMC4322935/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burdelya, Lyudmila G -- Krivokrysenko, Vadim I -- Tallant, Thomas C -- Strom, Evguenia -- Gleiberman, Anatoly S -- Gupta, Damodar -- Kurnasov, Oleg V -- Fort, Farrel L -- Osterman, Andrei L -- Didonato, Joseph A -- Feinstein, Elena -- Gudkov, Andrei V -- AI066497/AI/NIAID NIH HHS/ -- CA75179/CA/NCI NIH HHS/ -- CA84406/CA/NCI NIH HHS/ -- R01 CA084406/CA/NCI NIH HHS/ -- R01 CA084406-01A1/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 Apr 11;320(5873):226-30. doi: 10.1126/science.1154986.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Stress Biology, Roswell Park Cancer Institute, Buffalo, NY 14263, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18403709" target="_blank"〉PubMed〈/a〉

    Subdiffraction multicolor imaging of the nuclear periphery with 3D structured illumination microscopy (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2008-06-07
    Beschreibung: Fluorescence light microscopy allows multicolor visualization of cellular components with high specificity, but its utility has until recently been constrained by the intrinsic limit of spatial resolution. We applied three-dimensional structured illumination microscopy (3D-SIM) to circumvent this limit and to study the mammalian nucleus. By simultaneously imaging chromatin, nuclear lamina, and the nuclear pore complex (NPC), we observed several features that escape detection by conventional microscopy. We could resolve single NPCs that colocalized with channels in the lamin network and peripheral heterochromatin. We could differentially localize distinct NPC components and detect double-layered invaginations of the nuclear envelope in prophase as previously seen only by electron microscopy. Multicolor 3D-SIM opens new and facile possibilities to analyze subcellular structures beyond the diffraction limit of the emitted light.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2916659/" 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/PMC2916659/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schermelleh, Lothar -- Carlton, Peter M -- Haase, Sebastian -- Shao, Lin -- Winoto, Lukman -- Kner, Peter -- Burke, Brian -- Cardoso, M Cristina -- Agard, David A -- Gustafsson, Mats G L -- Leonhardt, Heinrich -- Sedat, John W -- GM-2501-25/GM/NIGMS NIH HHS/ -- R01 GM025101/GM/NIGMS NIH HHS/ -- R01 GM025101-25/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Jun 6;320(5881):1332-6. doi: 10.1126/science.1156947.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Integrated Protein Science, Department of Biology, Ludwig Maximilians University Munich, 82152 Planegg-Martinsried, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18535242" target="_blank"〉PubMed〈/a〉

    Species-specific transcription in mice carrying human chromosome 21 (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2008-09-13
    Beschreibung: Homologous sets of transcription factors direct conserved tissue-specific gene expression, yet transcription factor-binding events diverge rapidly between closely related species. We used hepatocytes from an aneuploid mouse strain carrying human chromosome 21 to determine, on a chromosomal scale, whether interspecies differences in transcriptional regulation are primarily directed by human genetic sequence or mouse nuclear environment. Virtually all transcription factor-binding locations, landmarks of transcription initiation, and the resulting gene expression observed in human hepatocytes were recapitulated across the entire human chromosome 21 in the mouse hepatocyte nucleus. Thus, in homologous tissues, genetic sequence is largely responsible for directing transcriptional programs; interspecies differences in epigenetic machinery, cellular environment, and transcription factors themselves play secondary roles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3717767/" 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/PMC3717767/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, Michael D -- Barbosa-Morais, Nuno L -- Schmidt, Dominic -- Conboy, Caitlin M -- Vanes, Lesley -- Tybulewicz, Victor L J -- Fisher, Elizabeth M C -- Tavare, Simon -- Odom, Duncan T -- 080174/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- G0601056/Medical Research Council/United Kingdom -- MC_U117527252/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Oct 17;322(5900):434-8. doi: 10.1126/science.1160930.

    Genetic ablation: targeted expression of a toxin gene causes microphthalmia in transgenic mice (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-12-11
    Beschreibung: Lineage-specific regulatory elements can be used to direct expression of a variety of genes to specific tissues in transgenic mice. If the hybrid constructs contain a gene encoding a cytotoxic gene product, then genetic ablation of a specific cell lineage can be achieved. We have generated six transgenic mice by introducing into fertilized eggs the mouse gamma 2-crystallin promoter fused to the coding region of the diphtheria toxin A-chain gene. Three of these mice and all the transgenic offspring analyzed were microphthalmic. The lenses of these mice displayed considerable heterogeneity: some were almost normal morphologically but reduced in size, whereas others were grossly aberrant and deficient in nuclear fiber cells. These studies indicate that programmed ablation of specific cell types can be stably transmitted through the germ line.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Breitman, M L -- Clapoff, S -- Rossant, J -- Tsui, L C -- Glode, L M -- Maxwell, I H -- Bernstein, A -- CA 42354/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1987 Dec 11;238(4833):1563-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mount Sinai Hospital Research Institute, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3685993" target="_blank"〉PubMed〈/a〉

    Efficacy of murine malaria sporozoite vaccines: implications for human vaccine development (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-04-24
    Beschreibung: As part of a study of potential vaccines against malaria, the protective efficacy of sporozoite subunit vaccines was determined by using the Plasmodium berghei murine malaria model. Mice were immunized with recombinant DNA-produced or synthetic peptide-carrier subunit vaccines derived from the repetitive epitopes of the Plasmodium berghei circumsporozoite gene, or with radiation-attenuated sporozoites. Immunization with subunit vaccines elicited humoral responses that were equivalent to or greater than those elicited by irradiated sporozoites, yet the protection against sporozoite challenge induced by either of the subunit vaccines was far less than that achieved by immunization with attenuated sporozoites. Passive and adoptive transfer studies demonstrated that subunit vaccines elicited predominantly antibody-mediated protection that was easily overcome whereas irradiated sporozoites induced potent cell-mediated immunity that protected against high challenge doses of sporozoites. These studies indicate that new strategies designed to induce cellular immunity will be required for efficacious sporozoite vaccines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Egan, J E -- Weber, J L -- Ballou, W R -- Hollingdale, M R -- Majarian, W R -- Gordon, D M -- Maloy, W L -- Hoffman, S L -- Wirtz, R A -- Schneider, I -- New York, N.Y. -- Science. 1987 Apr 24;236(4800):453-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3551073" target="_blank"〉PubMed〈/a〉

    Lhx2 selector activity specifies cortical identity and suppresses hippocampal organizer fate (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2008-01-19
    Beschreibung: The earliest step in creating the cerebral cortex is the specification of neuroepithelium to a cortical fate. Using mouse genetic mosaics and timed inactivations, we demonstrated that Lhx2 acts as a classic selector gene and essential intrinsic determinant of cortical identity. Lhx2 selector activity is restricted to an early critical period when stem cells comprise the cortical neuroepithelium, where it acts cell-autonomously to specify cortical identity and suppress alternative fates in a spatially dependent manner. Laterally, Lhx2 null cells adopt antihem identity, whereas medially they become cortical hem cells, which can induce and organize ectopic hippocampal fields. In addition to providing functional evidence for Lhx2 selector activity, these findings show that the cortical hem is a hippocampal organizer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2494603/" 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/PMC2494603/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mangale, Vishakha S -- Hirokawa, Karla E -- Satyaki, Prasad R V -- Gokulchandran, Nandini -- Chikbire, Satyadeep -- Subramanian, Lakshmi -- Shetty, Ashwin S -- Martynoga, Ben -- Paul, Jolly -- Mai, Mark V -- Li, Yuqing -- Flanagan, Lisa A -- Tole, Shubha -- Monuki, Edwin S -- 056684/Z/99/Z/Wellcome Trust/United Kingdom -- AG23583/AG/NIA NIH HHS/ -- MH02029/MH/NIMH NIH HHS/ -- NS053511/NS/NINDS NIH HHS/ -- NS07444/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2008 Jan 18;319(5861):304-9. doi: 10.1126/science.1151695.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Tata Institute of Fundamental Research, Mumbai 400005, India.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18202285" target="_blank"〉PubMed〈/a〉

    Beschreibung: Dynein and kinesin motor proteins transport cellular cargoes toward opposite ends of microtubule tracks. In neurons, microtubules are abundantly decorated with microtubule-associated proteins (MAPs) such as tau. Motor proteins thus encounter MAPs frequently along their path. To determine the effects of tau on dynein and kinesin motility, we conducted single-molecule studies of motor proteins moving along tau-decorated microtubules. Dynein tended to reverse direction, whereas kinesin tended to detach at patches of bound tau. Kinesin was inhibited at about a tenth of the tau concentration that inhibited dynein, and the microtubule-binding domain of tau was sufficient to inhibit motor activity. The differential modulation of dynein and kinesin motility suggests that MAPs can spatially regulate the balance of microtubule-dependent axonal transport.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2866193/" 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/PMC2866193/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dixit, Ram -- Ross, Jennifer L -- Goldman, Yale E -- Holzbaur, Erika L F -- GM-48661/GM/NIGMS NIH HHS/ -- P01 AR051174/AR/NIAMS NIH HHS/ -- P01 AR051174-050002/AR/NIAMS NIH HHS/ -- P01-AR-051174/AR/NIAMS NIH HHS/ -- R01 GM048661/GM/NIGMS NIH HHS/ -- R01 GM048661-16/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Feb 22;319(5866):1086-9. doi: 10.1126/science.1152993.
