Description: The most recent Ebola virus outbreak in West Africa, which was unprecedented in the number of cases and fatalities, geographic distribution, and number of nations affected, highlights the need for safe, effective, and readily available antiviral agents for treatment and prevention of acute Ebola virus (EBOV) disease (EVD) or sequelae. No antiviral therapeutics have yet received regulatory approval or demonstrated clinical efficacy. Here we report the discovery of a novel small molecule GS-5734, a monophosphoramidate prodrug of an adenosine analogue, with antiviral activity against EBOV. GS-5734 exhibits antiviral activity against multiple variants of EBOV and other filoviruses in cell-based assays. The pharmacologically active nucleoside triphosphate (NTP) is efficiently formed in multiple human cell types incubated with GS-5734 in vitro, and the NTP acts as an alternative substrate and RNA-chain terminator in primer-extension assays using a surrogate respiratory syncytial virus RNA polymerase. Intravenous administration of GS-5734 to nonhuman primates resulted in persistent NTP levels in peripheral blood mononuclear cells (half-life, 14 h) and distribution to sanctuary sites for viral replication including testes, eyes, and brain. In a rhesus monkey model of EVD, once-daily intravenous administration of 10 mg kg(-1) GS-5734 for 12 days resulted in profound suppression of EBOV replication and protected 100% of EBOV-infected animals against lethal disease, ameliorating clinical disease signs and pathophysiological markers, even when treatments were initiated three days after virus exposure when systemic viral RNA was detected in two out of six treated animals. These results show the first substantive post-exposure protection by a small-molecule antiviral compound against EBOV in nonhuman primates. The broad-spectrum antiviral activity of GS-5734 in vitro against other pathogenic RNA viruses, including filoviruses, arenaviruses, and coronaviruses, suggests the potential for wider medical use. GS-5734 is amenable to large-scale manufacturing, and clinical studies investigating the drug safety and pharmacokinetics are ongoing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Travis K -- Jordan, Robert -- Lo, Michael K -- Ray, Adrian S -- Mackman, Richard L -- Soloveva, Veronica -- Siegel, Dustin -- Perron, Michel -- Bannister, Roy -- Hui, Hon C -- Larson, Nate -- Strickley, Robert -- Wells, Jay -- Stuthman, Kelly S -- Van Tongeren, Sean A -- Garza, Nicole L -- Donnelly, Ginger -- Shurtleff, Amy C -- Retterer, Cary J -- Gharaibeh, Dima -- Zamani, Rouzbeh -- Kenny, Tara -- Eaton, Brett P -- Grimes, Elizabeth -- Welch, Lisa S -- Gomba, Laura -- Wilhelmsen, Catherine L -- Nichols, Donald K -- Nuss, Jonathan E -- Nagle, Elyse R -- Kugelman, Jeffrey R -- Palacios, Gustavo -- Doerffler, Edward -- Neville, Sean -- Carra, Ernest -- Clarke, Michael O -- Zhang, Lijun -- Lew, Willard -- Ross, Bruce -- Wang, Queenie -- Chun, Kwon -- Wolfe, Lydia -- Babusis, Darius -- Park, Yeojin -- Stray, Kirsten M -- Trancheva, Iva -- Feng, Joy Y -- Barauskas, Ona -- Xu, Yili -- Wong, Pamela -- Braun, Molly R -- Flint, Mike -- McMullan, Laura K -- Chen, Shan-Shan -- Fearns, Rachel -- Swaminathan, Swami -- Mayers, Douglas L -- Spiropoulou, Christina F -- Lee, William A -- Nichol, Stuart T -- Cihlar, Tomas -- Bavari, Sina -- R01 AI113321/AI/NIAID NIH HHS/ -- R01AI113321/AI/NIAID NIH HHS/ -- England -- Nature. 2016 Mar 17;531(7594):381-5. doi: 10.1038/nature17180.

Description: Mitral valve prolapse (MVP) is a common cardiac valve disease that affects nearly 1 in 40 individuals. It can manifest as mitral regurgitation and is the leading indication for mitral valve surgery. Despite a clear heritable component, the genetic aetiology leading to non-syndromic MVP has remained elusive. Four affected individuals from a large multigenerational family segregating non-syndromic MVP underwent capture sequencing of the linked interval on chromosome 11. We report a missense mutation in the DCHS1 gene, the human homologue of the Drosophila cell polarity gene dachsous (ds), that segregates with MVP in the family. Morpholino knockdown of the zebrafish homologue dachsous1b resulted in a cardiac atrioventricular canal defect that could be rescued by wild-type human DCHS1, but not by DCHS1 messenger RNA with the familial mutation. Further genetic studies identified two additional families in which a second deleterious DCHS1 mutation segregates with MVP. Both DCHS1 mutations reduce protein stability as demonstrated in zebrafish, cultured cells and, notably, in mitral valve interstitial cells (MVICs) obtained during mitral valve repair surgery of a proband. Dchs1(+/-) mice had prolapse of thickened mitral leaflets, which could be traced back to developmental errors in valve morphogenesis. DCHS1 deficiency in MVP patient MVICs, as well as in Dchs1(+/-) mouse MVICs, result in altered migration and cellular patterning, supporting these processes as aetiological underpinnings for the disease. Understanding the role of DCHS1 in mitral valve development and MVP pathogenesis holds potential for therapeutic insights for this very common disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4720389/" 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/PMC4720389/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Durst, Ronen -- Sauls, Kimberly -- Peal, David S -- deVlaming, Annemarieke -- Toomer, Katelynn -- Leyne, Maire -- Salani, Monica -- Talkowski, Michael E -- Brand, Harrison -- Perrocheau, Maelle -- Simpson, Charles -- Jett, Christopher -- Stone, Matthew R -- Charles, Florie -- Chiang, Colby -- Lynch, Stacey N -- Bouatia-Naji, Nabila -- Delling, Francesca N -- Freed, Lisa A -- Tribouilloy, Christophe -- Le Tourneau, Thierry -- LeMarec, Herve -- Fernandez-Friera, Leticia -- Solis, Jorge -- Trujillano, Daniel -- Ossowski, Stephan -- Estivill, Xavier -- Dina, Christian -- Bruneval, Patrick -- Chester, Adrian -- Schott, Jean-Jacques -- Irvine, Kenneth D -- Mao, Yaopan -- Wessels, Andy -- Motiwala, Tahirali -- Puceat, Michel -- Tsukasaki, Yoshikazu -- Menick, Donald R -- Kasiganesan, Harinath -- Nie, Xingju -- Broome, Ann-Marie -- Williams, Katherine -- Johnson, Amanda -- Markwald, Roger R -- Jeunemaitre, Xavier -- Hagege, Albert -- Levine, Robert A -- Milan, David J -- Norris, Russell A -- Slaugenhaupt, Susan A -- 1P30 GM103342/GM/NIGMS NIH HHS/ -- 8P20 GM103444-07/GM/NIGMS NIH HHS/ -- C06 RR018823/RR/NCRR NIH HHS/ -- I01 BX002327/BX/BLRD VA/ -- K24 HL67434/HL/NHLBI NIH HHS/ -- R00-MH095867/MH/NIMH NIH HHS/ -- R01 HL109004/HL/NHLBI NIH HHS/ -- R01 HL127692/HL/NHLBI NIH HHS/ -- R01-HL095696/HL/NHLBI NIH HHS/ -- R01-HL109004/HL/NHLBI NIH HHS/ -- R01-HL127692/HL/NHLBI NIH HHS/ -- R01-HL33756/HL/NHLBI NIH HHS/ -- R01HL109506/HL/NHLBI NIH HHS/ -- R01HL122906-01/HL/NHLBI NIH HHS/ -- R01HL72265/HL/NHLBI NIH HHS/ -- T32 HL007208/HL/NHLBI NIH HHS/ -- T32 HL007260/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Sep 3;525(7567):109-13. doi: 10.1038/nature14670.

Description: Observing marine mammal (MM) populations continuously in time and space over the immense ocean areas they inhabit is challenging but essential for gathering an unambiguous record of their distribution, as well as understanding their behaviour and interaction with prey species. Here we use passive ocean acoustic waveguide remote sensing (POAWRS) in an important North Atlantic feeding ground to instantaneously detect, localize and classify MM vocalizations from diverse species over an approximately 100,000 km(2) region. More than eight species of vocal MMs are found to spatially converge on fish spawning areas containing massive densely populated herring shoals at night-time and diffuse herring distributions during daytime. We find the vocal MMs divide the enormous fish prey field into species-specific foraging areas with varying degrees of spatial overlap, maintained for at least two weeks of the herring spawning period. The recorded vocalization rates are diel (24 h)-dependent for all MM species, with some significantly more vocal at night and others more vocal during the day. The four key baleen whale species of the region: fin, humpback, blue and minke have vocalization rate trends that are highly correlated to trends in fish shoaling density and to each other over the diel cycle. These results reveal the temporospatial dynamics of combined multi-species MM foraging activities in the vicinity of an extensive fish prey field that forms a massive ecological hotspot, and would be unattainable with conventional methodologies. Understanding MM behaviour and distributions is essential for management of marine ecosystems and for accessing anthropogenic impacts on these protected marine species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Delin -- Garcia, Heriberto -- Huang, Wei -- Tran, Duong D -- Jain, Ankita D -- Yi, Dong Hoon -- Gong, Zheng -- Jech, J Michael -- Godo, Olav Rune -- Makris, Nicholas C -- Ratilal, Purnima -- England -- Nature. 2016 Mar 17;531(7594):366-70. doi: 10.1038/nature16960.

Description: The human lens is comprised largely of crystallin proteins assembled into a highly ordered, interactive macro-structure essential for lens transparency and refractive index. Any disruption of intra- or inter-protein interactions will alter this delicate structure, exposing hydrophobic surfaces, with consequent protein aggregation and cataract formation. Cataracts are the most common cause of blindness worldwide, affecting tens of millions of people, and currently the only treatment is surgical removal of cataractous lenses. The precise mechanisms by which lens proteins both prevent aggregation and maintain lens transparency are largely unknown. Lanosterol is an amphipathic molecule enriched in the lens. It is synthesized by lanosterol synthase (LSS) in a key cyclization reaction of a cholesterol synthesis pathway. Here we identify two distinct homozygous LSS missense mutations (W581R and G588S) in two families with extensive congenital cataracts. Both of these mutations affect highly conserved amino acid residues and impair key catalytic functions of LSS. Engineered expression of wild-type, but not mutant, LSS prevents intracellular protein aggregation of various cataract-causing mutant crystallins. Treatment by lanosterol, but not cholesterol, significantly decreased preformed protein aggregates both in vitro and in cell-transfection experiments. We further show that lanosterol treatment could reduce cataract severity and increase transparency in dissected rabbit cataractous lenses in vitro and cataract severity in vivo in dogs. Our study identifies lanosterol as a key molecule in the prevention of lens protein aggregation and points to a novel strategy for cataract prevention and treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Ling -- Chen, Xiang-Jun -- Zhu, Jie -- Xi, Yi-Bo -- Yang, Xu -- Hu, Li-Dan -- Ouyang, Hong -- Patel, Sherrina H -- Jin, Xin -- Lin, Danni -- Wu, Frances -- Flagg, Ken -- Cai, Huimin -- Li, Gen -- Cao, Guiqun -- Lin, Ying -- Chen, Daniel -- Wen, Cindy -- Chung, Christopher -- Wang, Yandong -- Qiu, Austin -- Yeh, Emily -- Wang, Wenqiu -- Hu, Xun -- Grob, Seanna -- Abagyan, Ruben -- Su, Zhiguang -- Tjondro, Harry Christianto -- Zhao, Xi-Juan -- Luo, Hongrong -- Hou, Rui -- Perry, J Jefferson P -- Gao, Weiwei -- Kozak, Igor -- Granet, David -- Li, Yingrui -- Sun, Xiaodong -- Wang, Jun -- Zhang, Liangfang -- Liu, Yizhi -- Yan, Yong-Bin -- Zhang, Kang -- England -- Nature. 2015 Jul 30;523(7562):607-11. doi: 10.1038/nature14650.

Description: Cancers emerge from an ongoing Darwinian evolutionary process, often leading to multiple competing subclones within a single primary tumour. This evolutionary process culminates in the formation of metastases, which is the cause of 90% of cancer-related deaths. However, despite its clinical importance, little is known about the principles governing the dissemination of cancer cells to distant organs. Although the hypothesis that each metastasis originates from a single tumour cell is generally supported, recent studies using mouse models of cancer demonstrated the existence of polyclonal seeding from and interclonal cooperation between multiple subclones. Here we sought definitive evidence for the existence of polyclonal seeding in human malignancy and to establish the clonal relationship among different metastases in the context of androgen-deprived metastatic prostate cancer. Using whole-genome sequencing, we characterized multiple metastases arising from prostate tumours in ten patients. Integrated analyses of subclonal architecture revealed the patterns of metastatic spread in unprecedented detail. Metastasis-to-metastasis spread was found to be common, either through de novo monoclonal seeding of daughter metastases or, in five cases, through the transfer of multiple tumour clones between metastatic sites. Lesions affecting tumour suppressor genes usually occur as single events, whereas mutations in genes involved in androgen receptor signalling commonly involve multiple, convergent events in different metastases. Our results elucidate in detail the complex patterns of metastatic spread and further our understanding of the development of resistance to androgen-deprivation therapy in prostate cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4413032/" 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/PMC4413032/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gundem, Gunes -- Van Loo, Peter -- Kremeyer, Barbara -- Alexandrov, Ludmil B -- Tubio, Jose M C -- Papaemmanuil, Elli -- Brewer, Daniel S -- Kallio, Heini M L -- Hognas, Gunilla -- Annala, Matti -- Kivinummi, Kati -- Goody, Victoria -- Latimer, Calli -- O'Meara, Sarah -- Dawson, Kevin J -- Isaacs, William -- Emmert-Buck, Michael R -- Nykter, Matti -- Foster, Christopher -- Kote-Jarai, Zsofia -- Easton, Douglas -- Whitaker, Hayley C -- ICGC Prostate UK Group -- Neal, David E -- Cooper, Colin S -- Eeles, Rosalind A -- Visakorpi, Tapio -- Campbell, Peter J -- McDermott, Ultan -- Wedge, David C -- Bova, G Steven -- 077012/Wellcome Trust/United Kingdom -- A12758/Cancer Research UK/United Kingdom -- A14835/Cancer Research UK/United Kingdom -- CA92234/CA/NCI NIH HHS/ -- Cancer Research UK/United Kingdom -- Intramural NIH HHS/ -- England -- Nature. 2015 Apr 16;520(7547):353-7. doi: 10.1038/nature14347.

Description: Ancient DNA makes it possible to observe natural selection directly by analysing samples from populations before, during and after adaptation events. Here we report a genome-wide scan for selection using ancient DNA, capitalizing on the largest ancient DNA data set yet assembled: 230 West Eurasians who lived between 6500 and 300 bc, including 163 with newly reported data. The new samples include, to our knowledge, the first genome-wide ancient DNA from Anatolian Neolithic farmers, whose genetic material we obtained by extracting from petrous bones, and who we show were members of the population that was the source of Europe's first farmers. We also report a transect of the steppe region in Samara between 5600 and 300 bc, which allows us to identify admixture into the steppe from at least two external sources.

Description: Preclinical studies of viral vector-based HIV-1 vaccine candidates have previously shown partial protection against neutralization-resistant virus challenges in rhesus monkeys. In this study, we evaluated the protective efficacy of adenovirus serotype 26 (Ad26) vector priming followed by purified envelope (Env) glycoprotein boosting. Rhesus monkeys primed with Ad26 vectors expressing SIVsmE543 Env, Gag, and Pol and boosted with AS01B-adjuvanted SIVmac32H Env gp140 demonstrated complete protection in 50% of vaccinated animals against a series of repeated, heterologous, intrarectal SIVmac251 challenges that infected all controls. Protective efficacy correlated with the functionality of Env-specific antibody responses. Comparable protection was also observed with a similar Ad/Env vaccine against repeated, heterologous, intrarectal SHIV-SF162P3 challenges. These data demonstrate robust protection by Ad/Env vaccines against acquisition of neutralization-resistant virus challenges in rhesus monkeys.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4653134/" 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/PMC4653134/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barouch, Dan H -- Alter, Galit -- Broge, Thomas -- Linde, Caitlyn -- Ackerman, Margaret E -- Brown, Eric P -- Borducchi, Erica N -- Smith, Kaitlin M -- Nkolola, Joseph P -- Liu, Jinyan -- Shields, Jennifer -- Parenteau, Lily -- Whitney, James B -- Abbink, Peter -- Ng'ang'a, David M -- Seaman, Michael S -- Lavine, Christy L -- Perry, James R -- Li, Wenjun -- Colantonio, Arnaud D -- Lewis, Mark G -- Chen, Bing -- Wenschuh, Holger -- Reimer, Ulf -- Piatak, Michael -- Lifson, Jeffrey D -- Handley, Scott A -- Virgin, Herbert W -- Koutsoukos, Marguerite -- Lorin, Clarisse -- Voss, Gerald -- Weijtens, Mo -- Pau, Maria G -- Schuitemaker, Hanneke -- AI060354/AI/NIAID NIH HHS/ -- AI078526/AI/NIAID NIH HHS/ -- AI080289/AI/NIAID NIH HHS/ -- AI084794/AI/NIAID NIH HHS/ -- AI095985/AI/NIAID NIH HHS/ -- AI096040/AI/NIAID NIH HHS/ -- AI102660/AI/NIAID NIH HHS/ -- AI102691/AI/NIAID NIH HHS/ -- OD011170/OD/NIH HHS/ -- P30 AI060354/AI/NIAID NIH HHS/ -- R01 AI080289/AI/NIAID NIH HHS/ -- R01 AI084794/AI/NIAID NIH HHS/ -- R01 AI102660/AI/NIAID NIH HHS/ -- R01 AI102691/AI/NIAID NIH HHS/ -- R01 OD011170/OD/NIH HHS/ -- R37 AI080289/AI/NIAID NIH HHS/ -- U19 AI078526/AI/NIAID NIH HHS/ -- U19 AI095985/AI/NIAID NIH HHS/ -- U19 AI096040/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2015 Jul 17;349(6245):320-4. doi: 10.1126/science.aab3886.

Description: As tumors grow, they acquire mutations, some of which create neoantigens that influence the response of patients to immune checkpoint inhibitors. We explored the impact of neoantigen intratumor heterogeneity (ITH) on antitumor immunity. Through integrated analysis of ITH and neoantigen burden, we demonstrate a relationship between clonal neoantigen burden and overall survival in primary lung adenocarcinomas. CD8(+)tumor-infiltrating lymphocytes reactive to clonal neoantigens were identified in early-stage non-small cell lung cancer and expressed high levels of PD-1. Sensitivity to PD-1 and CTLA-4 blockade in patients with advanced NSCLC and melanoma was enhanced in tumors enriched for clonal neoantigens. T cells recognizing clonal neoantigens were detectable in patients with durable clinical benefit. Cytotoxic chemotherapy-induced subclonal neoantigens, contributing to an increased mutational load, were enriched in certain poor responders. These data suggest that neoantigen heterogeneity may influence immune surveillance and support therapeutic developments targeting clonal neoantigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGranahan, Nicholas -- Furness, Andrew J S -- Rosenthal, Rachel -- Ramskov, Sofie -- Lyngaa, Rikke -- Saini, Sunil Kumar -- Jamal-Hanjani, Mariam -- Wilson, Gareth A -- Birkbak, Nicolai J -- Hiley, Crispin T -- Watkins, Thomas B K -- Shafi, Seema -- Murugaesu, Nirupa -- Mitter, Richard -- Akarca, Ayse U -- Linares, Joseph -- Marafioti, Teresa -- Henry, Jake Y -- Van Allen, Eliezer M -- Miao, Diana -- Schilling, Bastian -- Schadendorf, Dirk -- Garraway, Levi A -- Makarov, Vladimir -- Rizvi, Naiyer A -- Snyder, Alexandra -- Hellmann, Matthew D -- Merghoub, Taha -- Wolchok, Jedd D -- Shukla, Sachet A -- Wu, Catherine J -- Peggs, Karl S -- Chan, Timothy A -- Hadrup, Sine R -- Quezada, Sergio A -- Swanton, Charles -- 12100/Cancer Research UK/United Kingdom -- 1R01CA155010-02/CA/NCI NIH HHS/ -- 1R01CA182461-01/CA/NCI NIH HHS/ -- 1R01CA184922-01/CA/NCI NIH HHS/ -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1463-9. doi: 10.1126/science.aaf1490.

Description: Little is known about how pro-obesity diets regulate tissue stem and progenitor cell function. Here we show that high-fat diet (HFD)-induced obesity augments the numbers and function of Lgr5(+) intestinal stem cells of the mammalian intestine. Mechanistically, a HFD induces a robust peroxisome proliferator-activated receptor delta (PPAR-delta) signature in intestinal stem cells and progenitor cells (non-intestinal stem cells), and pharmacological activation of PPAR-delta recapitulates the effects of a HFD on these cells. Like a HFD, ex vivo treatment of intestinal organoid cultures with fatty acid constituents of the HFD enhances the self-renewal potential of these organoid bodies in a PPAR-delta-dependent manner. Notably, HFD- and agonist-activated PPAR-delta signalling endow organoid-initiating capacity to progenitors, and enforced PPAR-delta signalling permits these progenitors to form in vivo tumours after loss of the tumour suppressor Apc. These findings highlight how diet-modulated PPAR-delta activation alters not only the function of intestinal stem and progenitor cells, but also their capacity to initiate tumours.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4846772/" 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/PMC4846772/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beyaz, Semir -- Mana, Miyeko D -- Roper, Jatin -- Kedrin, Dmitriy -- Saadatpour, Assieh -- Hong, Sue-Jean -- Bauer-Rowe, Khristian E -- Xifaras, Michael E -- Akkad, Adam -- Arias, Erika -- Pinello, Luca -- Katz, Yarden -- Shinagare, Shweta -- Abu-Remaileh, Monther -- Mihaylova, Maria M -- Lamming, Dudley W -- Dogum, Rizkullah -- Guo, Guoji -- Bell, George W -- Selig, Martin -- Nielsen, G Petur -- Gupta, Nitin -- Ferrone, Cristina R -- Deshpande, Vikram -- Yuan, Guo-Cheng -- Orkin, Stuart H -- Sabatini, David M -- Yilmaz, Omer H -- AI47389/AI/NIAID NIH HHS/ -- DK043351/DK/NIDDK NIH HHS/ -- K08 CA198002/CA/NCI NIH HHS/ -- K99 AG041765/AG/NIA NIH HHS/ -- K99 AG045144/AG/NIA NIH HHS/ -- P30 CA014051/CA/NCI NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- R00 AG041765/AG/NIA NIH HHS/ -- R00 AG045144/AG/NIA NIH HHS/ -- R01 AI047389/AI/NIAID NIH HHS/ -- R01 CA103866/CA/NCI NIH HHS/ -- R01 CA129105/CA/NCI NIH HHS/ -- R37 AI047389/AI/NIAID NIH HHS/ -- T32DK007191/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2016 Mar 3;531(7592):53-8. doi: 10.1038/nature17173.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The David H.

Description: Despite the magnitude of the Ebola virus disease (EVD) outbreak in West Africa, there is still a fundamental lack of knowledge about the pathophysiology of EVD. In particular, very little is known about human immune responses to Ebola virus. Here we evaluate the physiology of the human T cell immune response in EVD patients at the time of admission to the Ebola Treatment Center in Guinea, and longitudinally until discharge or death. Through the use of multiparametric flow cytometry established by the European Mobile Laboratory in the field, we identify an immune signature that is unique in EVD fatalities. Fatal EVD was characterized by a high percentage of CD4(+) and CD8(+) T cells expressing the inhibitory molecules CTLA-4 and PD-1, which correlated with elevated inflammatory markers and high virus load. Conversely, surviving individuals showed significantly lower expression of CTLA-4 and PD-1 as well as lower inflammation, despite comparable overall T cell activation. Concomitant with virus clearance, survivors mounted a robust Ebola-virus-specific T cell response. Our findings suggest that dysregulation of the T cell response is a key component of EVD pathophysiology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4876960/" 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/PMC4876960/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ruibal, Paula -- Oestereich, Lisa -- Ludtke, Anja -- Becker-Ziaja, Beate -- Wozniak, David M -- Kerber, Romy -- Korva, Misa -- Cabeza-Cabrerizo, Mar -- Bore, Joseph A -- Koundouno, Fara Raymond -- Duraffour, Sophie -- Weller, Romy -- Thorenz, Anja -- Cimini, Eleonora -- Viola, Domenico -- Agrati, Chiara -- Repits, Johanna -- Afrough, Babak -- Cowley, Lauren A -- Ngabo, Didier -- Hinzmann, Julia -- Mertens, Marc -- Vitoriano, Ines -- Logue, Christopher H -- Boettcher, Jan Peter -- Pallasch, Elisa -- Sachse, Andreas -- Bah, Amadou -- Nitzsche, Katja -- Kuisma, Eeva -- Michel, Janine -- Holm, Tobias -- Zekeng, Elsa-Gayle -- Garcia-Dorival, Isabel -- Wolfel, Roman -- Stoecker, Kilian -- Fleischmann, Erna -- Strecker, Thomas -- Di Caro, Antonino -- Avsic-Zupanc, Tatjana -- Kurth, Andreas -- Meschi, Silvia -- Mely, Stephane -- Newman, Edmund -- Bocquin, Anne -- Kis, Zoltan -- Kelterbaum, Anne -- Molkenthin, Peter -- Carletti, Fabrizio -- Portmann, Jasmine -- Wolff, Svenja -- Castilletti, Concetta -- Schudt, Gordian -- Fizet, Alexandra -- Ottowell, Lisa J -- Herker, Eva -- Jacobs, Thomas -- Kretschmer, Birte -- Severi, Ettore -- Ouedraogo, Nobila -- Lago, Mar -- Negredo, Anabel -- Franco, Leticia -- Anda, Pedro -- Schmiedel, Stefan -- Kreuels, Benno -- Wichmann, Dominic -- Addo, Marylyn M -- Lohse, Ansgar W -- De Clerck, Hilde -- Nanclares, Carolina -- Jonckheere, Sylvie -- Van Herp, Michel -- Sprecher, Armand -- Xiaojiang, Gao -- Carrington, Mary -- Miranda, Osvaldo -- Castro, Carlos M -- Gabriel, Martin -- Drury, Patrick -- Formenty, Pierre -- Diallo, Boubacar -- Koivogui, Lamine -- Magassouba, N'Faly -- Carroll, Miles W -- Gunther, Stephan -- Munoz-Fontela, Cesar -- HHSN261200800001E/PHS HHS/ -- Z01 BC010791-01/Intramural NIH HHS/ -- Z01 BC010791-02/Intramural NIH HHS/ -- Z01 BC010792-01/Intramural NIH HHS/ -- England -- Nature. 2016 May 5;533(7601):100-4. doi: 10.1038/nature17949.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Heinrich Pette Institute, Leibniz Institute for Experimental Virology, 20251 Hamburg, Germany. ; Bernhard Nocht Institute for Tropical Medicine, World Health Organization Collaborating Center for Arbovirus and Hemorrhagic Fever Reference and Research, 20359 Hamburg, Germany. ; German Center for Infection Research (DZIF), Partner Sites Hamburg, Munich, and Marburg, Germany. ; European Mobile Laboratory Consortium, Bernhard-Nocht-Institute for Tropical Medicine, D-20359 Hamburg, Germany. ; Institute of Microbiology and Immunology, Faculty of Medicine, University of Ljubljana, 1000 Ljubljana, Slovenia. ; Institute of Experimental Virology, Twincore, Center for Experimental and Clinical Infection Research, 30625 Hannover, Germany. ; Hannover Medical School, 30625 Hannover, Germany. ; National Institute for Infectious Diseases 'Lazzaro Spallanzani', 00149 Rome, Italy. ; Public Health England, Porton Down, Salisbury SP4 0JG, UK. ; Public Health England, Colindale Ave, London NW9 5EQ, UK. ; Robert Koch Institute, 13353 Berlin, Germany. ; Friedrich Loeffler Institute, 17493 Greifswald-Island of Riems, Germany. ; Swiss Tropical and Public Health Institute, 4051 Basel, Switzerland. ; Institute of Infection and Global Health, University of Liverpool, Liverpool L69 7BE, UK. ; Bundeswehr Institute of Microbiology, 80937 Munich, Germany. ; Institute of Virology, Philipps University, 35043 Marburg, Germany. ; Laboratoire P4-Jean Merieux, US003 INSERM, 69365 Lyon, France. ; National Center for Epidemiology, Hungarian National Biosafety Laboratory, H1097 Budapest, Hungary. ; European Centre for Disease Prevention and Control, 171 65 Solna, Sweden. ; Federal Office for Civil Protection, CH-3700 Spiez, Switzerland. ; Unite de Biologie des Infections Virales Emergentes, Institut Pasteur, 69365 Lyon, France. ; Eurice, European Research and Project Office, 10115 Berlin, Germany. ; Infectious Diseases Unit, Internal Medicine Service, Hospital La Paz, 28046 Madrid, Spain. ; National Center of Microbiology, Institute of Health 'Carlos III', 28220 Madrid, Spain. ; University Medical Center Hamburg-Eppendorf, 20246 Hamburg, Germany. ; Medecins sans Frontieres, B-1050 Brussels, Belgium. ; Cancer and Inflammation Program, Laboratory of Experimental Immunology, Leidos Biomedical Research, Frederick National Laboratory for Cancer Research, Frederick, Maryland 21702, USA. ; Ragon Institute of MGH, MIT and Harvard, Cambridge, Massachusetts 02139, USA. ; Hospital Militar Central Dr. Carlos J.
