    Rare variant in scavenger receptor BI raises HDL cholesterol and increases risk of coronary heart disease (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-03-12
    Description: Scavenger receptor BI (SR-BI) is the major receptor for high-density lipoprotein (HDL) cholesterol (HDL-C). In humans, high amounts of HDL-C in plasma are associated with a lower risk of coronary heart disease (CHD). Mice that have depleted Scarb1 (SR-BI knockout mice) have markedly elevated HDL-C levels but, paradoxically, increased atherosclerosis. The impact of SR-BI on HDL metabolism and CHD risk in humans remains unclear. Through targeted sequencing of coding regions of lipid-modifying genes in 328 individuals with extremely high plasma HDL-C levels, we identified a homozygote for a loss-of-function variant, in which leucine replaces proline 376 (P376L), in SCARB1, the gene encoding SR-BI. The P376L variant impairs posttranslational processing of SR-BI and abrogates selective HDL cholesterol uptake in transfected cells, in hepatocyte-like cells derived from induced pluripotent stem cells from the homozygous subject, and in mice. Large population-based studies revealed that subjects who are heterozygous carriers of the P376L variant have significantly increased levels of plasma HDL-C. P376L carriers have a profound HDL-related phenotype and an increased risk of CHD (odds ratio = 1.79, which is statistically significant).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zanoni, Paolo -- Khetarpal, Sumeet A -- Larach, Daniel B -- Hancock-Cerutti, William F -- Millar, John S -- Cuchel, Marina -- DerOhannessian, Stephanie -- Kontush, Anatol -- Surendran, Praveen -- Saleheen, Danish -- Trompet, Stella -- Jukema, J Wouter -- De Craen, Anton -- Deloukas, Panos -- Sattar, Naveed -- Ford, Ian -- Packard, Chris -- Majumder, Abdullah al Shafi -- Alam, Dewan S -- Di Angelantonio, Emanuele -- Abecasis, Goncalo -- Chowdhury, Rajiv -- Erdmann, Jeanette -- Nordestgaard, Borge G -- Nielsen, Sune F -- Tybjaerg-Hansen, Anne -- Schmidt, Ruth Frikke -- Kuulasmaa, Kari -- Liu, Dajiang J -- Perola, Markus -- Blankenberg, Stefan -- Salomaa, Veikko -- Mannisto, Satu -- Amouyel, Philippe -- Arveiler, Dominique -- Ferrieres, Jean -- Muller-Nurasyid, Martina -- Ferrario, Marco -- Kee, Frank -- Willer, Cristen J -- Samani, Nilesh -- Schunkert, Heribert -- Butterworth, Adam S -- Howson, Joanna M M -- Peloso, Gina M -- Stitziel, Nathan O -- Danesh, John -- Kathiresan, Sekar -- Rader, Daniel J -- CHD Exome+ Consortium -- CARDIoGRAM Exome Consortium -- Global Lipids Genetics Consortium -- R01 DK089256/DK/NIDDK NIH HHS/ -- R01 HL117078/HL/NHLBI NIH HHS/ -- TL1 RR024133/RR/NCRR NIH HHS/ -- TL1R000138/PHS HHS/ -- TL1RR024133/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1166-71. doi: 10.1126/science.aad3517.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Genetics and Medicine, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA. ; Departments of Genetics and Medicine, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA.

    Therapeutic efficacy of the small molecule GS-5734 against Ebola virus in rhesus monkeys (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-03-05
    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.

    Clonal neoantigens elicit T cell immunoreactivity and sensitivity to immune checkpoint blockade (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-03-05
    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.

    Zika virus in the Americas: Early epidemiological and genetic findings (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-03-26
    Description: Brazil has experienced an unprecedented epidemic of Zika virus (ZIKV), with ~30,000 cases reported to date. ZIKV was first detected in Brazil in May 2015, and cases of microcephaly potentially associated with ZIKV infection were identified in November 2015. We performed next-generation sequencing to generate seven Brazilian ZIKV genomes sampled from four self-limited cases, one blood donor, one fatal adult case, and one newborn with microcephaly and congenital malformations. Results of phylogenetic and molecular clock analyses show a single introduction of ZIKV into the Americas, which we estimated to have occurred between May and December 2013, more than 12 months before the detection of ZIKV in Brazil. The estimated date of origin coincides with an increase in air passengers to Brazil from ZIKV-endemic areas, as well as with reported outbreaks in the Pacific Islands. ZIKV genomes from Brazil are phylogenetically interspersed with those from other South American and Caribbean countries. Mapping mutations onto existing structural models revealed the context of viral amino acid changes present in the outbreak lineage; however, no shared amino acid changes were found among the three currently available virus genomes from microcephaly cases. Municipality-level incidence data indicate that reports of suspected microcephaly in Brazil best correlate with ZIKV incidence around week 17 of pregnancy, although this correlation does not demonstrate causation. Our genetic description and analysis of ZIKV isolates in Brazil provide a baseline for future studies of the evolution and molecular epidemiology of this emerging virus in the Americas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faria, Nuno Rodrigues -- Azevedo, Raimunda do Socorro da Silva -- Kraemer, Moritz U G -- Souza, Renato -- Cunha, Mariana Sequetin -- Hill, Sarah C -- Theze, Julien -- Bonsall, Michael B -- Bowden, Thomas A -- Rissanen, Ilona -- Rocco, Iray Maria -- Nogueira, Juliana Silva -- Maeda, Adriana Yurika -- Vasami, Fernanda Giseli da Silva -- Macedo, Fernando Luiz de Lima -- Suzuki, Akemi -- Rodrigues, Sueli Guerreiro -- Cruz, Ana Cecilia Ribeiro -- Nunes, Bruno Tardeli -- Medeiros, Daniele Barbosa de Almeida -- Rodrigues, Daniela Sueli Guerreiro -- Nunes Queiroz, Alice Louize -- da Silva, Eliana Vieira Pinto -- Henriques, Daniele Freitas -- Travassos da Rosa, Elisabeth Salbe -- de Oliveira, Consuelo Silva -- Martins, Livia Caricio -- Vasconcelos, Helena Baldez -- Casseb, Livia Medeiros Neves -- Simith, Darlene de Brito -- Messina, Jane P -- Abade, Leandro -- Lourenco, Jose -- Carlos Junior Alcantara, Luiz -- de Lima, Maricelia Maia -- Giovanetti, Marta -- Hay, Simon I -- de Oliveira, Rodrigo Santos -- Lemos, Poliana da Silva -- de Oliveira, Layanna Freitas -- de Lima, Clayton Pereira Silva -- da Silva, Sandro Patroca -- de Vasconcelos, Janaina Mota -- Franco, Luciano -- Cardoso, Jedson Ferreira -- Vianez-Junior, Joao Lidio da Silva Goncalves -- Mir, Daiana -- Bello, Gonzalo -- Delatorre, Edson -- Khan, Kamran -- Creatore, Marisa -- Coelho, Giovanini Evelim -- de Oliveira, Wanderson Kleber -- Tesh, Robert -- Pybus, Oliver G -- Nunes, Marcio R T -- Vasconcelos, Pedro F C -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 095066/Wellcome Trust/United Kingdom -- 102427/Wellcome Trust/United Kingdom -- MR/L009528/1/Medical Research Council/United Kingdom -- R24 AT 120942/AT/NCCIH NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):345-9. doi: 10.1126/science.aaf5036.

    High-fat diet enhances stemness and tumorigenicity of intestinal progenitors (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-03-05
    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.

    Unique human immune signature of Ebola virus disease in Guinea (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-05-07
    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.

    The necrosome promotes pancreatic oncogenesis via CXCL1 and Mincle-induced immune suppression (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-04-07
    Description: Neoplastic pancreatic epithelial cells are believed to die through caspase 8-dependent apoptotic cell death, and chemotherapy is thought to promote tumour apoptosis. Conversely, cancer cells often disrupt apoptosis to survive. Another type of programmed cell death is necroptosis (programmed necrosis), but its role in pancreatic ductal adenocarcinoma (PDA) is unclear. There are many potential inducers of necroptosis in PDA, including ligation of tumour necrosis factor receptor 1 (TNFR1), CD95, TNF-related apoptosis-inducing ligand (TRAIL) receptors, Toll-like receptors, reactive oxygen species, and chemotherapeutic drugs. Here we report that the principal components of the necrosome, receptor-interacting protein (RIP)1 and RIP3, are highly expressed in PDA and are further upregulated by the chemotherapy drug gemcitabine. Blockade of the necrosome in vitro promoted cancer cell proliferation and induced an aggressive oncogenic phenotype. By contrast, in vivo deletion of RIP3 or inhibition of RIP1 protected against oncogenic progression in mice and was associated with the development of a highly immunogenic myeloid and T cell infiltrate. The immune-suppressive tumour microenvironment associated with intact RIP1/RIP3 signalling depended in part on necroptosis-induced expression of the chemokine attractant CXCL1, and CXCL1 blockade protected against PDA. Moreover, cytoplasmic SAP130 (a subunit of the histone deacetylase complex) was expressed in PDA in a RIP1/RIP3-dependent manner, and Mincle--its cognate receptor--was upregulated in tumour-infiltrating myeloid cells. Ligation of Mincle by SAP130 promoted oncogenesis, whereas deletion of Mincle protected against oncogenesis and phenocopied the immunogenic reprogramming of the tumour microenvironment that was induced by RIP3 deletion. Cellular depletion suggested that whereas inhibitory macrophages promote tumorigenesis in PDA, they lose their immune-suppressive effects when RIP3 or Mincle is deleted. Accordingly, T cells, which are not protective against PDA progression in mice with intact RIP3 or Mincle signalling, are reprogrammed into indispensable mediators of anti-tumour immunity in the absence of RIP3 or Mincle. Our work describes parallel networks of necroptosis-induced CXCL1 and Mincle signalling that promote macrophage-induced adaptive immune suppression and thereby enable PDA progression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4833566/" 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/PMC4833566/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seifert, Lena -- Werba, Gregor -- Tiwari, Shaun -- Giao Ly, Nancy Ngoc -- Alothman, Sara -- Alqunaibit, Dalia -- Avanzi, Antonina -- Barilla, Rocky -- Daley, Donnele -- Greco, Stephanie H -- Torres-Hernandez, Alejandro -- Pergamo, Matthew -- Ochi, Atsuo -- Zambirinis, Constantinos P -- Pansari, Mridul -- Rendon, Mauricio -- Tippens, Daniel -- Hundeyin, Mautin -- Mani, Vishnu R -- Hajdu, Cristina -- Engle, Dannielle -- Miller, George -- CA155649/CA/NCI NIH HHS/ -- CA168611/CA/NCI NIH HHS/ -- CA193111/CA/NCI NIH HHS/ -- P30CA016087/CA/NCI NIH HHS/ -- R01 CA168611/CA/NCI NIH HHS/ -- T32 CA193111/CA/NCI NIH HHS/ -- UL1 TR000038/TR/NCATS NIH HHS/ -- England -- Nature. 2016 Apr 14;532(7598):245-9. doi: 10.1038/nature17403.

    Health and population effects of rare gene knockouts in adult humans with related parents (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-03-05
    Description: Examining complete gene knockouts within a viable organism can inform on gene function. We sequenced the exomes of 3222 British adults of Pakistani heritage with high parental relatedness, discovering 1111 rare-variant homozygous genotypes with predicted loss of function (knockouts) in 781 genes. We observed 13.7% fewer homozygous knockout genotypes than we expected, implying an average load of 1.6 recessive-lethal-equivalent loss-of-function (LOF) variants per adult. When genetic data were linked to the individuals' lifelong health records, we observed no significant relationship between gene knockouts and clinical consultation or prescription rate. In this data set, we identified a healthy PRDM9-knockout mother and performed phased genome sequencing on her, her child, and control individuals. Our results show that meiotic recombination sites are localized away from PRDM9-dependent hotspots. Thus, natural LOF variants inform on essential genetic loci and demonstrate PRDM9 redundancy in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Narasimhan, Vagheesh M -- Hunt, Karen A -- Mason, Dan -- Baker, Christopher L -- Karczewski, Konrad J -- Barnes, Michael R -- Barnett, Anthony H -- Bates, Chris -- Bellary, Srikanth -- Bockett, Nicholas A -- Giorda, Kristina -- Griffiths, Christopher J -- Hemingway, Harry -- Jia, Zhilong -- Kelly, M Ann -- Khawaja, Hajrah A -- Lek, Monkol -- McCarthy, Shane -- McEachan, Rosie -- O'Donnell-Luria, Anne -- Paigen, Kenneth -- Parisinos, Constantinos A -- Sheridan, Eamonn -- Southgate, Laura -- Tee, Louise -- Thomas, Mark -- Xue, Yali -- Schnall-Levin, Michael -- Petkov, Petko M -- Tyler-Smith, Chris -- Maher, Eamonn R -- Trembath, Richard C -- MacArthur, Daniel G -- Wright, John -- Durbin, Richard -- van Heel, David A -- GM 099640/GM/NIGMS NIH HHS/ -- MR/M009017/1/Medical Research Council/United Kingdom -- R01 GM104371/GM/NIGMS NIH HHS/ -- R01GM104371/GM/NIGMS NIH HHS/ -- WT098051/Wellcome Trust/United Kingdom -- WT099769/Wellcome Trust/United Kingdom -- WT101597/Wellcome Trust/United Kingdom -- WT102627/Wellcome Trust/United Kingdom -- British Heart Foundation/United Kingdom -- Arthritis Research UK/United Kingdom -- Cancer Research UK/United Kingdom -- Department of Health/United Kingdom -- Chief Scientist Office/United Kingdom -- New York, N.Y. -- Science. 2016 Apr 22;352(6284):474-7. doi: 10.1126/science.aac8624.

    Mx1 reveals innate pathways to antiviral resistance and lethal influenza disease (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-04-23
    Description: Influenza A virus (IAV) causes up to half a million deaths worldwide annually, 90% of which occur in older adults. We show that IAV-infected monocytes from older humans have impaired antiviral interferon production but retain intact inflammasome responses. To understand the in vivo consequence, we used mice expressing a functional Mx gene encoding a major interferon-induced effector against IAV in humans. In Mx1-intact mice with weakened resistance due to deficiencies in Mavs and Tlr7, we found an elevated respiratory bacterial burden. Notably, mortality in the absence of Mavs and Tlr7 was independent of viral load or MyD88-dependent signaling but dependent on bacterial burden, caspase-1/11, and neutrophil-dependent tissue damage. Therefore, in the context of weakened antiviral resistance, vulnerability to IAV disease is a function of caspase-dependent pathology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pillai, Padmini S -- Molony, Ryan D -- Martinod, Kimberly -- Dong, Huiping -- Pang, Iris K -- Tal, Michal C -- Solis, Angel G -- Bielecki, Piotr -- Mohanty, Subhasis -- Trentalange, Mark -- Homer, Robert J -- Flavell, Richard A -- Wagner, Denisa D -- Montgomery, Ruth R -- Shaw, Albert C -- Staeheli, Peter -- Iwasaki, Akiko -- 5T32HL066987-13/HL/NHLBI NIH HHS/ -- AI062428/AI/NIAID NIH HHS/ -- AI064705/AI/NIAID NIH HHS/ -- AI081884/AI/NIAID NIH HHS/ -- F31 AG039163/AG/NIA NIH HHS/ -- HHSN272201100019C/PHS HHS/ -- K24 AG02489/AG/NIA NIH HHS/ -- K24 AG042489/AG/NIA NIH HHS/ -- N01 AI500031/AI/NIAID NIH HHS/ -- P30 AG21342/AG/NIA NIH HHS/ -- R01HL102101/HL/NHLBI NIH HHS/ -- R01HL125501/HL/NHLBI NIH HHS/ -- T32 AI007019-36/AI/NIAID NIH HHS/ -- T32 AI007019-38/AI/NIAID NIH HHS/ -- T32 AI055403/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Apr 22;352(6284):463-6. doi: 10.1126/science.aaf3926.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunobiology, Yale School of Medicine, New Haven, CT 06520, USA. ; Program in Cellular and Molecular Medicine, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA. ; Section of Infectious Diseases, Department of Internal Medicine, Yale School of Medicine, New Haven, Connecticut, USA. ; Department of Internal Medicine, Yale School of Medicine, New Haven, Connecticut, USA. ; Department of Pathology, Yale School of Medicine, New Haven, CT 06520, USA. ; Department of Immunobiology, Yale School of Medicine, New Haven, CT 06520, USA.

Prdm9 is the only mammalian speciation gene yet identified and is responsible for sterility phenotypes in male hybrids of certain mouse subspecies. To investigate PRDM9 binding and its role in fertility and meiotic recombination, we humanized the DNA-binding domain of PRDM9 in C57BL/6 mice. This change repositions DSB hotspots and completely restores fertility in male hybrids. Here we show that alteration of one Prdm9 allele impacts the behaviour of DSBs controlled by the other allele at chromosome-wide scales. These effects correlate strongly with the degree to which each PRDM9 variant binds both homologues at the DSB sites it controls. Furthermore, higher genome-wide levels of such 'symmetric' PRDM9 binding associate with increasing fertility measures, and comparisons of individual hotspots suggest binding symmetry plays a downstream role in the recombination process. These findings reveal that subspecies-specific degradation of PRDM9 binding sites by meiotic drive, which steadily increases asymmetric PRDM9 binding, has impacts beyond simply changing hotspot positions, and strongly support a direct involvement in hybrid infertility. Because such meiotic drive occurs across mammals, PRDM9 may play a wider, yet transient, role in the early stages of speciation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4756437/" 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/PMC4756437/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davies, Benjamin -- Hatton, Edouard -- Altemose, Nicolas -- Hussin, Julie G -- Pratto, Florencia -- Zhang, Gang -- Hinch, Anjali Gupta -- Moralli, Daniela -- Biggs, Daniel -- Diaz, Rebeca -- Preece, Chris -- Li, Ran -- Bitoun, Emmanuelle -- Brick, Kevin -- Green, Catherine M -- Camerini-Otero, R Daniel -- Myers, Simon R -- Donnelly, Peter -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 095552/Z/11/Z/Wellcome Trust/United Kingdom -- 098387/Z/12/Z/Wellcome Trust/United Kingdom -- Intramural NIH HHS/ -- England -- Nature. 2016 Feb 11;530(7589):171-6. doi: 10.1038/nature16931.
