    Description: An extensive literature shows that astrocytes exhibit metabotropic glutamate receptor 5 (mGluR5)-dependent increases in cytosolic calcium ions (Ca(2+)) in response to glutamatergic transmission and, in turn, modulate neuronal activity by their Ca(2+)-dependent release of gliotransmitters. These findings, based on studies of young rodents, have led to the concept of the tripartite synapse, in which astrocytes actively participate in neurotransmission. Using genomic analysis, immunoelectron microscopy, and two-photon microscopy of astrocytic Ca(2+) signaling in vivo, we found that astrocytic expression of mGluR5 is developmentally regulated and is undetectable after postnatal week 3. In contrast, mGluR3, whose activation inhibits adenylate cyclase but not calcium signaling, was expressed in astrocytes at all developmental stages. Neuroglial signaling in the adult brain may therefore occur in a manner fundamentally distinct from that exhibited during development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3569008/" 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/PMC3569008/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sun, Wei -- McConnell, Evan -- Pare, Jean-Francois -- Xu, Qiwu -- Chen, Michael -- Peng, Weiguo -- Lovatt, Ditte -- Han, Xiaoning -- Smith, Yoland -- Nedergaard, Maiken -- NS075177/NS/NINDS NIH HHS/ -- NS078304/NS/NINDS NIH HHS/ -- P51OD011132/OD/NIH HHS/ -- P51RR000165/RR/NCRR NIH HHS/ -- R01 NS075177/NS/NINDS NIH HHS/ -- R01 NS078167/NS/NINDS NIH HHS/ -- R01 NS078304/NS/NINDS NIH HHS/ -- RR00165/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2013 Jan 11;339(6116):197-200. doi: 10.1126/science.1226740.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Glial Disease and Therapeutics, Center for Translational Neuromedicine, University of Rochester, Rochester, NY 14642, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23307741" target="_blank"〉PubMed〈/a〉

    Description: Hybrid metal nanoparticles can allow separate reaction steps to occur in close proximity at different metal sites and accelerate catalysis. We synthesized iron-nickel hydroxide-platinum (transition metal-OH-Pt) nanoparticles with diameters below 5 nanometers and showed that they are highly efficient for carbon monoxide (CO) oxidation catalysis at room temperature. We characterized the composition and structure of the transition metal-OH-Pt interface and showed that Ni(2+) plays a key role in stabilizing the interface against dehydration. Density functional theory and isotope-labeling experiments revealed that the OH groups at the Fe(3+)-OH-Pt interfaces readily react with CO adsorbed nearby to directly yield carbon dioxide (CO2) and simultaneously produce coordinatively unsaturated Fe sites for O2 activation. The oxide-supported PtFeNi nanocatalyst rapidly and fully removed CO from humid air without decay in activity for 1 month.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Guangxu -- Zhao, Yun -- Fu, Gang -- Duchesne, Paul N -- Gu, Lin -- Zheng, Yanping -- Weng, Xuefei -- Chen, Mingshu -- Zhang, Peng -- Pao, Chih-Wen -- Lee, Jyh-Fu -- Zheng, Nanfeng -- New York, N.Y. -- Science. 2014 May 2;344(6183):495-9. doi: 10.1126/science.1252553.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory for Physical Chemistry of Solid Surfaces, Collaborative Innovation Center of Chemistry for Energy Materials, National Engineering Laboratory for Green Chemical Productions of Alcohols, Ethers, and Esters, and Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24786074" target="_blank"〉PubMed〈/a〉

    Description: Glucose homeostasis is a vital and complex process, and its disruption can cause hyperglycaemia and type II diabetes mellitus. Glucokinase (GK), a key enzyme that regulates glucose homeostasis, converts glucose to glucose-6-phosphate in pancreatic beta-cells, liver hepatocytes, specific hypothalamic neurons, and gut enterocytes. In hepatocytes, GK regulates glucose uptake and glycogen synthesis, suppresses glucose production, and is subject to the endogenous inhibitor GK regulatory protein (GKRP). During fasting, GKRP binds, inactivates and sequesters GK in the nucleus, which removes GK from the gluconeogenic process and prevents a futile cycle of glucose phosphorylation. Compounds that directly hyperactivate GK (GK activators) lower blood glucose levels and are being evaluated clinically as potential therapeutics for the treatment of type II diabetes mellitus. However, initial reports indicate that an increased risk of hypoglycaemia is associated with some GK activators. To mitigate the risk of hypoglycaemia, we sought to increase GK activity by blocking GKRP. Here we describe the identification of two potent small-molecule GK-GKRP disruptors (AMG-1694 and AMG-3969) that normalized blood glucose levels in several rodent models of diabetes. These compounds potently reversed the inhibitory effect of GKRP on GK activity and promoted GK translocation both in vitro (isolated hepatocytes) and in vivo (liver). A co-crystal structure of full-length human GKRP in complex with AMG-1694 revealed a previously unknown binding pocket in GKRP distinct from that of the phosphofructose-binding site. Furthermore, with AMG-1694 and AMG-3969 (but not GK activators), blood glucose lowering was restricted to diabetic and not normoglycaemic animals. These findings exploit a new cellular mechanism for lowering blood glucose levels with reduced potential for hypoglycaemic risk in patients with type II diabetes mellitus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lloyd, David J -- St Jean, David J Jr -- Kurzeja, Robert J M -- Wahl, Robert C -- Michelsen, Klaus -- Cupples, Rod -- Chen, Michelle -- Wu, John -- Sivits, Glenn -- Helmering, Joan -- Komorowski, Renee -- Ashton, Kate S -- Pennington, Lewis D -- Fotsch, Christopher -- Vazir, Mukta -- Chen, Kui -- Chmait, Samer -- Zhang, Jiandong -- Liu, Longbin -- Norman, Mark H -- Andrews, Kristin L -- Bartberger, Michael D -- Van, Gwyneth -- Galbreath, Elizabeth J -- Vonderfecht, Steven L -- Wang, Minghan -- Jordan, Steven R -- Veniant, Murielle M -- Hale, Clarence -- England -- Nature. 2013 Dec 19;504(7480):437-40. doi: 10.1038/nature12724.

    Description: Vaccines prevent infectious disease largely by inducing protective neutralizing antibodies against vulnerable epitopes. Several major pathogens have resisted traditional vaccine development, although vulnerable epitopes targeted by neutralizing antibodies have been identified for several such cases. Hence, new vaccine design methods to induce epitope-specific neutralizing antibodies are needed. Here we show, with a neutralization epitope from respiratory syncytial virus, that computational protein design can generate small, thermally and conformationally stable protein scaffolds that accurately mimic the viral epitope structure and induce potent neutralizing antibodies. These scaffolds represent promising leads for the research and development of a human respiratory syncytial virus vaccine needed to protect infants, young children and the elderly. More generally, the results provide proof of principle for epitope-focused and scaffold-based vaccine design, and encourage the evaluation and further development of these strategies for a variety of other vaccine targets, including antigenically highly variable pathogens such as human immunodeficiency virus and influenza.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4260937/" 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/PMC4260937/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Correia, Bruno E -- Bates, John T -- Loomis, Rebecca J -- Baneyx, Gretchen -- Carrico, Chris -- Jardine, Joseph G -- Rupert, Peter -- Correnti, Colin -- Kalyuzhniy, Oleksandr -- Vittal, Vinayak -- Connell, Mary J -- Stevens, Eric -- Schroeter, Alexandria -- Chen, Man -- Macpherson, Skye -- Serra, Andreia M -- Adachi, Yumiko -- Holmes, Margaret A -- Li, Yuxing -- Klevit, Rachel E -- Graham, Barney S -- Wyatt, Richard T -- Baker, David -- Strong, Roland K -- Crowe, James E Jr -- Johnson, Philip R -- Schief, William R -- 1R01AI102766-01A1/AI/NIAID NIH HHS/ -- 1UM1AI100663/AI/NIAID NIH HHS/ -- 2T32GM007270/GM/NIGMS NIH HHS/ -- 5R21AI088554/AI/NIAID NIH HHS/ -- P01 AI094419/AI/NIAID NIH HHS/ -- P01AI094419/AI/NIAID NIH HHS/ -- P30 AI036214/AI/NIAID NIH HHS/ -- P30 AI045008/AI/NIAID NIH HHS/ -- P30AI36214/AI/NIAID NIH HHS/ -- R01 AI102766/AI/NIAID NIH HHS/ -- R21 AI088554/AI/NIAID NIH HHS/ -- T32 CA080416/CA/NCI NIH HHS/ -- T32 GM007270/GM/NIGMS NIH HHS/ -- T32CA080416/CA/NCI NIH HHS/ -- U54 AI 005714/AI/NIAID NIH HHS/ -- U54 AI057141/AI/NIAID NIH HHS/ -- UM1 AI100663/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2014 Mar 13;507(7491):201-6. doi: 10.1038/nature12966.

    Description: The Pacific oyster Crassostrea gigas belongs to one of the most species-rich but genomically poorly explored phyla, the Mollusca. Here we report the sequencing and assembly of the oyster genome using short reads and a fosmid-pooling strategy, along with transcriptomes of development and stress response and the proteome of the shell. The oyster genome is highly polymorphic and rich in repetitive sequences, with some transposable elements still actively shaping variation. Transcriptome studies reveal an extensive set of genes responding to environmental stress. The expansion of genes coding for heat shock protein 70 and inhibitors of apoptosis is probably central to the oyster's adaptation to sessile life in the highly stressful intertidal zone. Our analyses also show that shell formation in molluscs is more complex than currently understood and involves extensive participation of cells and their exosomes. The oyster genome sequence fills a void in our understanding of the Lophotrochozoa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Guofan -- Fang, Xiaodong -- Guo, Ximing -- Li, Li -- Luo, Ruibang -- Xu, Fei -- Yang, Pengcheng -- Zhang, Linlin -- Wang, Xiaotong -- Qi, Haigang -- Xiong, Zhiqiang -- Que, Huayong -- Xie, Yinlong -- Holland, Peter W H -- Paps, Jordi -- Zhu, Yabing -- Wu, Fucun -- Chen, Yuanxin -- Wang, Jiafeng -- Peng, Chunfang -- Meng, Jie -- Yang, Lan -- Liu, Jun -- Wen, Bo -- Zhang, Na -- Huang, Zhiyong -- Zhu, Qihui -- Feng, Yue -- Mount, Andrew -- Hedgecock, Dennis -- Xu, Zhe -- Liu, Yunjie -- Domazet-Loso, Tomislav -- Du, Yishuai -- Sun, Xiaoqing -- Zhang, Shoudu -- Liu, Binghang -- Cheng, Peizhou -- Jiang, Xuanting -- Li, Juan -- Fan, Dingding -- Wang, Wei -- Fu, Wenjing -- Wang, Tong -- Wang, Bo -- Zhang, Jibiao -- Peng, Zhiyu -- Li, Yingxiang -- Li, Na -- Wang, Jinpeng -- Chen, Maoshan -- He, Yan -- Tan, Fengji -- Song, Xiaorui -- Zheng, Qiumei -- Huang, Ronglian -- Yang, Hailong -- Du, Xuedi -- Chen, Li -- Yang, Mei -- Gaffney, Patrick M -- Wang, Shan -- Luo, Longhai -- She, Zhicai -- Ming, Yao -- Huang, Wen -- Zhang, Shu -- Huang, Baoyu -- Zhang, Yong -- Qu, Tao -- Ni, Peixiang -- Miao, Guoying -- Wang, Junyi -- Wang, Qiang -- Steinberg, Christian E W -- Wang, Haiyan -- Li, Ning -- Qian, Lumin -- Zhang, Guojie -- Li, Yingrui -- Yang, Huanming -- Liu, Xiao -- Wang, Jian -- Yin, Ye -- Wang, Jun -- 268513/European Research Council/International -- England -- Nature. 2012 Oct 4;490(7418):49-54. doi: 10.1038/nature11413.

    Description: The fission yeast clade--comprising Schizosaccharomyces pombe, S. octosporus, S. cryophilus, and S. japonicus--occupies the basal branch of Ascomycete fungi and is an important model of eukaryote biology. A comparative annotation of these genomes identified a near extinction of transposons and the associated innovation of transposon-free centromeres. Expression analysis established that meiotic genes are subject to antisense transcription during vegetative growth, which suggests a mechanism for their tight regulation. In addition, trans-acting regulators control new genes within the context of expanded functional modules for meiosis and stress response. Differences in gene content and regulation also explain why, unlike the budding yeast of Saccharomycotina, fission yeasts cannot use ethanol as a primary carbon source. These analyses elucidate the genome structure and gene regulation of fission yeast and provide tools for investigation across the Schizosaccharomyces clade.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3131103/" 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/PMC3131103/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rhind, Nicholas -- Chen, Zehua -- Yassour, Moran -- Thompson, Dawn A -- Haas, Brian J -- Habib, Naomi -- Wapinski, Ilan -- Roy, Sushmita -- Lin, Michael F -- Heiman, David I -- Young, Sarah K -- Furuya, Kanji -- Guo, Yabin -- Pidoux, Alison -- Chen, Huei Mei -- Robbertse, Barbara -- Goldberg, Jonathan M -- Aoki, Keita -- Bayne, Elizabeth H -- Berlin, Aaron M -- Desjardins, Christopher A -- Dobbs, Edward -- Dukaj, Livio -- Fan, Lin -- FitzGerald, Michael G -- French, Courtney -- Gujja, Sharvari -- Hansen, Klavs -- Keifenheim, Dan -- Levin, Joshua Z -- Mosher, Rebecca A -- Muller, Carolin A -- Pfiffner, Jenna -- Priest, Margaret -- Russ, Carsten -- Smialowska, Agata -- Swoboda, Peter -- Sykes, Sean M -- Vaughn, Matthew -- Vengrova, Sonya -- Yoder, Ryan -- Zeng, Qiandong -- Allshire, Robin -- Baulcombe, David -- Birren, Bruce W -- Brown, William -- Ekwall, Karl -- Kellis, Manolis -- Leatherwood, Janet -- Levin, Henry -- Margalit, Hanah -- Martienssen, Rob -- Nieduszynski, Conrad A -- Spatafora, Joseph W -- Friedman, Nir -- Dalgaard, Jacob Z -- Baumann, Peter -- Niki, Hironori -- Regev, Aviv -- Nusbaum, Chad -- BB/E023754/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- DP1 OD003958/OD/NIH HHS/ -- R01 GM069957/GM/NIGMS NIH HHS/ -- R01 GM076396/GM/NIGMS NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54 HG003067-06/HG/NHGRI NIH HHS/ -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 May 20;332(6032):930-6. doi: 10.1126/science.1203357.

    Description: Respiratory syncytial virus (RSV) is the leading cause of hospitalization for children under 5 years of age. We sought to engineer a viral antigen that provides greater protection than currently available vaccines and focused on antigenic site O, a metastable site specific to the prefusion state of the RSV fusion (F) glycoprotein, as this site is targeted by extremely potent RSV-neutralizing antibodies. Structure-based design yielded stabilized versions of RSV F that maintained antigenic site O when exposed to extremes of pH, osmolality, and temperature. Six RSV F crystal structures provided atomic-level data on how introduced cysteine residues and filled hydrophobic cavities improved stability. Immunization with site O-stabilized variants of RSV F in mice and macaques elicited levels of RSV-specific neutralizing activity many times the protective threshold.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4461862/" 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/PMC4461862/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McLellan, Jason S -- Chen, Man -- Joyce, M Gordon -- Sastry, Mallika -- Stewart-Jones, Guillaume B E -- Yang, Yongping -- Zhang, Baoshan -- Chen, Lei -- Srivatsan, Sanjay -- Zheng, Anqi -- Zhou, Tongqing -- Graepel, Kevin W -- Kumar, Azad -- Moin, Syed -- Boyington, Jeffrey C -- Chuang, Gwo-Yu -- Soto, Cinque -- Baxa, Ulrich -- Bakker, Arjen Q -- Spits, Hergen -- Beaumont, Tim -- Zheng, Zizheng -- Xia, Ningshao -- Ko, Sung-Youl -- Todd, John-Paul -- Rao, Srinivas -- Graham, Barney S -- Kwong, Peter D -- ZIA AI005024-11/Intramural NIH HHS/ -- ZIA AI005061-10/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2013 Nov 1;342(6158):592-8. doi: 10.1126/science.1243283.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vaccine Research Center, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24179220" target="_blank"〉PubMed〈/a〉

To overcome this obstacle, we identified prefusion-specific antibodies that were substantially more potent than the prophylactic antibody palivizumab. The cocrystal structure for one of these antibodies, D25, in complex with the F glycoprotein revealed D25 to lock F in its prefusion state by binding to a quaternary epitope at the trimer apex. Electron microscopy showed that two other antibodies, AM22 and 5C4, also bound to the newly identified site of vulnerability, which we named antigenic site O. These studies should enable design of improved vaccine antigens and define new targets for passive prevention of RSV-induced disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4459498/" 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/PMC4459498/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McLellan, Jason S -- Chen, Man -- Leung, Sherman -- Graepel, Kevin W -- Du, Xiulian -- Yang, Yongping -- Zhou, Tongqing -- Baxa, Ulrich -- Yasuda, Etsuko -- Beaumont, Tim -- Kumar, Azad -- Modjarrad, Kayvon -- Zheng, Zizheng -- Zhao, Min -- Xia, Ningshao -- Kwong, Peter D -- Graham, Barney S -- ZIA AI005024-11/Intramural NIH HHS/ -- ZIA AI005061-10/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2013 May 31;340(6136):1113-7. doi: 10.1126/science.1234914.
