    Legumes symbioses: absence of Nod genes in photosynthetic bradyrhizobia (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-06-02
    Description: Leguminous plants (such as peas and soybeans) and rhizobial soil bacteria are symbiotic partners that communicate through molecular signaling pathways, resulting in the formation of nodules on legume roots and occasionally stems that house nitrogen-fixing bacteria. Nodule formation has been assumed to be exclusively initiated by the binding of bacterial, host-specific lipochito-oligosaccharidic Nod factors, encoded by the nodABC genes, to kinase-like receptors of the plant. Here we show by complete genome sequencing of two symbiotic, photosynthetic, Bradyrhizobium strains, BTAi1 and ORS278, that canonical nodABC genes and typical lipochito-oligosaccharidic Nod factors are not required for symbiosis in some legumes. Mutational analyses indicated that these unique rhizobia use an alternative pathway to initiate symbioses, where a purine derivative may play a key role in triggering nodule formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giraud, Eric -- Moulin, Lionel -- Vallenet, David -- Barbe, Valerie -- Cytryn, Eddie -- Avarre, Jean-Christophe -- Jaubert, Marianne -- Simon, Damien -- Cartieaux, Fabienne -- Prin, Yves -- Bena, Gilles -- Hannibal, Laure -- Fardoux, Joel -- Kojadinovic, Mila -- Vuillet, Laurie -- Lajus, Aurelie -- Cruveiller, Stephane -- Rouy, Zoe -- Mangenot, Sophie -- Segurens, Beatrice -- Dossat, Carole -- Franck, William L -- Chang, Woo-Suk -- Saunders, Elizabeth -- Bruce, David -- Richardson, Paul -- Normand, Philippe -- Dreyfus, Bernard -- Pignol, David -- Stacey, Gary -- Emerich, David -- Vermeglio, Andre -- Medigue, Claudine -- Sadowsky, Michael -- New York, N.Y. -- Science. 2007 Jun 1;316(5829):1307-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Recherche pour le Developpement, Centre de Cooperation International en Recherche Agronomique pour le Developpement, Institut National de la Recherche Agronomique, Universite Montpellier 2, France. giraud@mpl.ird.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17540897" target="_blank"〉PubMed〈/a〉

    An overlapping protein-coding region in influenza A virus segment 3 modulates the host response (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-30
    Description: Influenza A virus (IAV) infection leads to variable and imperfectly understood pathogenicity. We report that segment 3 of the virus contains a second open reading frame ("X-ORF"), accessed via ribosomal frameshifting. The frameshift product, termed PA-X, comprises the endonuclease domain of the viral PA protein with a C-terminal domain encoded by the X-ORF and functions to repress cellular gene expression. PA-X also modulates IAV virulence in a mouse infection model, acting to decrease pathogenicity. Loss of PA-X expression leads to changes in the kinetics of the global host response, which notably includes increases in inflammatory, apoptotic, and T lymphocyte-signaling pathways. Thus, we have identified a previously unknown IAV protein that modulates the host response to infection, a finding with important implications for understanding IAV pathogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3552242/" 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/PMC3552242/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jagger, B W -- Wise, H M -- Kash, J C -- Walters, K-A -- Wills, N M -- Xiao, Y-L -- Dunfee, R L -- Schwartzman, L M -- Ozinsky, A -- Bell, G L -- Dalton, R M -- Lo, A -- Efstathiou, S -- Atkins, J F -- Firth, A E -- Taubenberger, J K -- Digard, P -- 073126/Wellcome Trust/United Kingdom -- 088789/Wellcome Trust/United Kingdom -- G0700815/Medical Research Council/United Kingdom -- G0700815(82260)/Medical Research Council/United Kingdom -- G9800943/Medical Research Council/United Kingdom -- MR/J002232/1/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2012 Jul 13;337(6091):199-204. doi: 10.1126/science.1222213.

    The Fusarium graminearum genome reveals a link between localized polymorphism and pathogen specialization (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-09-08
    Description: We sequenced and annotated the genome of the filamentous fungus Fusarium graminearum, a major pathogen of cultivated cereals. Very few repetitive sequences were detected, and the process of repeat-induced point mutation, in which duplicated sequences are subject to extensive mutation, may partially account for the reduced repeat content and apparent low number of paralogous (ancestrally duplicated) genes. A second strain of F. graminearum contained more than 10,000 single-nucleotide polymorphisms, which were frequently located near telomeres and within other discrete chromosomal segments. Many highly polymorphic regions contained sets of genes implicated in plant-fungus interactions and were unusually divergent, with higher rates of recombination. These regions of genome innovation may result from selection due to interactions of F. graminearum with its plant hosts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cuomo, Christina A -- Guldener, Ulrich -- Xu, Jin-Rong -- Trail, Frances -- Turgeon, B Gillian -- Di Pietro, Antonio -- Walton, Jonathan D -- Ma, Li-Jun -- Baker, Scott E -- Rep, Martijn -- Adam, Gerhard -- Antoniw, John -- Baldwin, Thomas -- Calvo, Sarah -- Chang, Yueh-Long -- Decaprio, David -- Gale, Liane R -- Gnerre, Sante -- Goswami, Rubella S -- Hammond-Kosack, Kim -- Harris, Linda J -- Hilburn, Karen -- Kennell, John C -- Kroken, Scott -- Magnuson, Jon K -- Mannhaupt, Gertrud -- Mauceli, Evan -- Mewes, Hans-Werner -- Mitterbauer, Rudolf -- Muehlbauer, Gary -- Munsterkotter, Martin -- Nelson, David -- O'donnell, Kerry -- Ouellet, Therese -- Qi, Weihong -- Quesneville, Hadi -- Roncero, M Isabel G -- Seong, Kye-Yong -- Tetko, Igor V -- Urban, Martin -- Waalwijk, Cees -- Ward, Todd J -- Yao, Jiqiang -- Birren, Bruce W -- Kistler, H Corby -- U54 HG003067/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 7;317(5843):1400-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute of the Massachusetts Institute of Technology and Harvard, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17823352" target="_blank"〉PubMed〈/a〉

    Evolutionarily assembled cis-regulatory module at a human ciliopathy locus (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-28
    Description: Neighboring genes are often coordinately expressed within cis-regulatory modules, but evidence that nonparalogous genes share functions in mammals is lacking. Here, we report that mutation of either TMEM138 or TMEM216 causes a phenotypically indistinguishable human ciliopathy, Joubert syndrome. Despite a lack of sequence homology, the genes are aligned in a head-to-tail configuration and joined by chromosomal rearrangement at the amphibian-to-reptile evolutionary transition. Expression of the two genes is mediated by a conserved regulatory element in the noncoding intergenic region. Coordinated expression is important for their interdependent cellular role in vesicular transport to primary cilia. Hence, during vertebrate evolution of genes involved in ciliogenesis, nonparalogous genes were arranged to a functional gene cluster with shared regulatory elements.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3671610/" 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/PMC3671610/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Jeong Ho -- Silhavy, Jennifer L -- Lee, Ji Eun -- Al-Gazali, Lihadh -- Thomas, Sophie -- Davis, Erica E -- Bielas, Stephanie L -- Hill, Kiley J -- Iannicelli, Miriam -- Brancati, Francesco -- Gabriel, Stacey B -- Russ, Carsten -- Logan, Clare V -- Sharif, Saghira Malik -- Bennett, Christopher P -- Abe, Masumi -- Hildebrandt, Friedhelm -- Diplas, Bill H -- Attie-Bitach, Tania -- Katsanis, Nicholas -- Rajab, Anna -- Koul, Roshan -- Sztriha, Laszlo -- Waters, Elizabeth R -- Ferro-Novick, Susan -- Woods, C Geoffrey -- Johnson, Colin A -- Valente, Enza Maria -- Zaki, Maha S -- Gleeson, Joseph G -- DK068306/DK/NIDDK NIH HHS/ -- DK072301/DK/NIDDK NIH HHS/ -- DK075972/DK/NIDDK NIH HHS/ -- DK090917/DK/NIDDK NIH HHS/ -- EY021872/EY/NEI NIH HHS/ -- G0700073/Medical Research Council/United Kingdom -- GGP08145/Telethon/Italy -- HD042601/HD/NICHD NIH HHS/ -- NS04843/NS/NINDS NIH HHS/ -- NS052455/NS/NINDS NIH HHS/ -- P30 CA023100/CA/NCI NIH HHS/ -- P30NS047101/NS/NINDS NIH HHS/ -- R01 DK068306/DK/NIDDK NIH HHS/ -- R01 DK072301/DK/NIDDK NIH HHS/ -- R01 DK075972/DK/NIDDK NIH HHS/ -- R01 EY021872/EY/NEI NIH HHS/ -- R01 HD042601/HD/NICHD NIH HHS/ -- R01 NS048453/NS/NINDS NIH HHS/ -- R01 NS052455/NS/NINDS NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Feb 24;335(6071):966-9. doi: 10.1126/science.1213506.

    Comparative analysis of bat genomes provides insight into the evolution of flight and immunity (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-22
    Description: Bats are the only mammals capable of sustained flight and are notorious reservoir hosts for some of the world's most highly pathogenic viruses, including Nipah, Hendra, Ebola, and severe acute respiratory syndrome (SARS). To identify genetic changes associated with the development of bat-specific traits, we performed whole-genome sequencing and comparative analyses of two distantly related species, fruit bat Pteropus alecto and insectivorous bat Myotis davidii. We discovered an unexpected concentration of positively selected genes in the DNA damage checkpoint and nuclear factor kappaB pathways that may be related to the origin of flight, as well as expansion and contraction of important gene families. Comparison of bat genomes with other mammalian species has provided new insights into bat biology and evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Guojie -- Cowled, Christopher -- Shi, Zhengli -- Huang, Zhiyong -- Bishop-Lilly, Kimberly A -- Fang, Xiaodong -- Wynne, James W -- Xiong, Zhiqiang -- Baker, Michelle L -- Zhao, Wei -- Tachedjian, Mary -- Zhu, Yabing -- Zhou, Peng -- Jiang, Xuanting -- Ng, Justin -- Yang, Lan -- Wu, Lijun -- Xiao, Jin -- Feng, Yue -- Chen, Yuanxin -- Sun, Xiaoqing -- Zhang, Yong -- Marsh, Glenn A -- Crameri, Gary -- Broder, Christopher C -- Frey, Kenneth G -- Wang, Lin-Fa -- Wang, Jun -- New York, N.Y. -- Science. 2013 Jan 25;339(6118):456-60. doi: 10.1126/science.1230835.

    Glacial survival of boreal trees in northern Scandinavia (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-03
    Description: It is commonly believed that trees were absent in Scandinavia during the last glaciation and first recolonized the Scandinavian Peninsula with the retreat of its ice sheet some 9000 years ago. Here, we show the presence of a rare mitochondrial DNA haplotype of spruce that appears unique to Scandinavia and with its highest frequency to the west-an area believed to sustain ice-free refugia during most of the last ice age. We further show the survival of DNA from this haplotype in lake sediments and pollen of Trondelag in central Norway dating back ~10,300 years and chloroplast DNA of pine and spruce in lake sediments adjacent to the ice-free Andoya refugium in northwestern Norway as early as ~22,000 and 17,700 years ago, respectively. Our findings imply that conifer trees survived in ice-free refugia of Scandinavia during the last glaciation, challenging current views on survival and spread of trees as a response to climate changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parducci, Laura -- Jorgensen, Tina -- Tollefsrud, Mari Mette -- Elverland, Ellen -- Alm, Torbjorn -- Fontana, Sonia L -- Bennett, K D -- Haile, James -- Matetovici, Irina -- Suyama, Yoshihisa -- Edwards, Mary E -- Andersen, Kenneth -- Rasmussen, Morten -- Boessenkool, Sanne -- Coissac, Eric -- Brochmann, Christian -- Taberlet, Pierre -- Houmark-Nielsen, Michael -- Larsen, Nicolaj Krog -- Orlando, Ludovic -- Gilbert, M Thomas P -- Kjaer, Kurt H -- Alsos, Inger Greve -- Willerslev, Eske -- New York, N.Y. -- Science. 2012 Mar 2;335(6072):1083-6. doi: 10.1126/science.1216043.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Genetics, Evolutionary Biology Centre, Uppsala University, Uppsala, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22383845" target="_blank"〉PubMed〈/a〉

    IFITM3 restricts the morbidity and mortality associated with influenza (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-03-27
    Description: The 2009 H1N1 influenza pandemic showed the speed with which a novel respiratory virus can spread and the ability of a generally mild infection to induce severe morbidity and mortality in a subset of the population. Recent in vitro studies show that the interferon-inducible transmembrane (IFITM) protein family members potently restrict the replication of multiple pathogenic viruses. Both the magnitude and breadth of the IFITM proteins' in vitro effects suggest that they are critical for intrinsic resistance to such viruses, including influenza viruses. Using a knockout mouse model, we now test this hypothesis directly and find that IFITM3 is essential for defending the host against influenza A virus in vivo. Mice lacking Ifitm3 display fulminant viral pneumonia when challenged with a normally low-pathogenicity influenza virus, mirroring the destruction inflicted by the highly pathogenic 1918 'Spanish' influenza. Similar increased viral replication is seen in vitro, with protection rescued by the re-introduction of Ifitm3. To test the role of IFITM3 in human influenza virus infection, we assessed the IFITM3 alleles of individuals hospitalized with seasonal or pandemic influenza H1N1/09 viruses. We find that a statistically significant number of hospitalized subjects show enrichment for a minor IFITM3 allele (SNP rs12252-C) that alters a splice acceptor site, and functional assays show the minor CC genotype IFITM3 has reduced influenza virus restriction in vitro. Together these data reveal that the action of a single intrinsic immune effector, IFITM3, profoundly alters the course of influenza virus infection in mouse and humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3648786/" 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/PMC3648786/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Everitt, Aaron R -- Clare, Simon -- Pertel, Thomas -- John, Sinu P -- Wash, Rachael S -- Smith, Sarah E -- Chin, Christopher R -- Feeley, Eric M -- Sims, Jennifer S -- Adams, David J -- Wise, Helen M -- Kane, Leanne -- Goulding, David -- Digard, Paul -- Anttila, Verneri -- Baillie, J Kenneth -- Walsh, Tim S -- Hume, David A -- Palotie, Aarno -- Xue, Yali -- Colonna, Vincenza -- Tyler-Smith, Chris -- Dunning, Jake -- Gordon, Stephen B -- GenISIS Investigators -- MOSAIC Investigators -- Smyth, Rosalind L -- Openshaw, Peter J -- Dougan, Gordon -- Brass, Abraham L -- Kellam, Paul -- 090382/Wellcome Trust/United Kingdom -- 090382/Z/09/Z/Wellcome Trust/United Kingdom -- 090385/Z/09/Z/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- 13031/Cancer Research UK/United Kingdom -- DHCS/04/G121/68/Department of Health/United Kingdom -- G0600371/Medical Research Council/United Kingdom -- G0600511/Medical Research Council/United Kingdom -- G0800767/Medical Research Council/United Kingdom -- G0800777/Medical Research Council/United Kingdom -- G0802752/Medical Research Council/United Kingdom -- G0901697/Medical Research Council/United Kingdom -- G1000758/Medical Research Council/United Kingdom -- MC_G1001212/Medical Research Council/United Kingdom -- MC_U122785833/Medical Research Council/United Kingdom -- P30 DK043351/DK/NIDDK NIH HHS/ -- R01 AI091786/AI/NIAID NIH HHS/ -- R01AI091786/AI/NIAID NIH HHS/ -- Chief Scientist Office/United Kingdom -- Medical Research Council/United Kingdom -- England -- Nature. 2012 Mar 25;484(7395):519-23. doi: 10.1038/nature10921.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton CB10 1SA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22446628" target="_blank"〉PubMed〈/a〉

    Strict evolutionary conservation followed rapid gene loss on human and rhesus Y chromosomes (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-03-01
    Description: The human X and Y chromosomes evolved from an ordinary pair of autosomes during the past 200-300 million years. The human MSY (male-specific region of Y chromosome) retains only three percent of the ancestral autosomes' genes owing to genetic decay. This evolutionary decay was driven by a series of five 'stratification' events. Each event suppressed X-Y crossing over within a chromosome segment or 'stratum', incorporated that segment into the MSY and subjected its genes to the erosive forces that attend the absence of crossing over. The last of these events occurred 30 million years ago, 5 million years before the human and Old World monkey lineages diverged. Although speculation abounds regarding ongoing decay and looming extinction of the human Y chromosome, remarkably little is known about how many MSY genes were lost in the human lineage in the 25 million years that have followed its separation from the Old World monkey lineage. To investigate this question, we sequenced the MSY of the rhesus macaque, an Old World monkey, and compared it to the human MSY. We discovered that during the last 25 million years MSY gene loss in the human lineage was limited to the youngest stratum (stratum 5), which comprises three percent of the human MSY. In the older strata, which collectively comprise the bulk of the human MSY, gene loss evidently ceased more than 25 million years ago. Likewise, the rhesus MSY has not lost any older genes (from strata 1-4) during the past 25 million years, despite its major structural differences to the human MSY. The rhesus MSY is simpler, with few amplified gene families or palindromes that might enable intrachromosomal recombination and repair. We present an empirical reconstruction of human MSY evolution in which each stratum transitioned from rapid, exponential loss of ancestral genes to strict conservation through purifying selection.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3292678/" 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/PMC3292678/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hughes, Jennifer F -- Skaletsky, Helen -- Brown, Laura G -- Pyntikova, Tatyana -- Graves, Tina -- Fulton, Robert S -- Dugan, Shannon -- Ding, Yan -- Buhay, Christian J -- Kremitzki, Colin -- Wang, Qiaoyan -- Shen, Hua -- Holder, Michael -- Villasana, Donna -- Nazareth, Lynne V -- Cree, Andrew -- Courtney, Laura -- Veizer, Joelle -- Kotkiewicz, Holland -- Cho, Ting-Jan -- Koutseva, Natalia -- Rozen, Steve -- Muzny, Donna M -- Warren, Wesley C -- Gibbs, Richard A -- Wilson, Richard K -- Page, David C -- R01 HG000257/HG/NHGRI NIH HHS/ -- R01 HG000257-17/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Feb 22;483(7387):82-6. doi: 10.1038/nature10843.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Biology, Massachusetts Institute of Technology, 9 Cambridge Center, Cambridge, Massachusetts 02142, USA. jhughes@wi.mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22367542" target="_blank"〉PubMed〈/a〉

    Phosphorylation of NLRC4 is critical for inflammasome activation (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-08-14
    Description: NLRC4 is a cytosolic member of the NOD-like receptor family that is expressed in innate immune cells. It senses indirectly bacterial flagellin and type III secretion systems, and responds by assembling an inflammasome complex that promotes caspase-1 activation and pyroptosis. Here we use knock-in mice expressing NLRC4 with a carboxy-terminal 3xFlag tag to identify phosphorylation of NLRC4 on a single, evolutionarily conserved residue, Ser 533, following infection of macrophages with Salmonella enterica serovar Typhimurium (also known as Salmonella typhimurium). Western blotting with a NLRC4 phospho-Ser 533 antibody confirmed that this post-translational modification occurs only in the presence of stimuli known to engage NLRC4 and not the related protein NLRP3 or AIM2. Nlrc4(-/-) macrophages reconstituted with NLRC4 mutant S533A, unlike those reconstituted with wild-type NLRC4, did not activate caspase-1 and pyroptosis in response to S. typhimurium, indicating that S533 phosphorylation is critical for NLRC4 inflammasome function. Conversely, phosphomimetic NLRC4 S533D caused rapid macrophage pyroptosis without infection. Biochemical purification of the NLRC4-phosphorylating activity and a screen of kinase inhibitors identified PRKCD (PKCdelta) as a candidate NLRC4 kinase. Recombinant PKCdelta phosphorylated NLRC4 S533 in vitro, immunodepletion of PKCdelta from macrophage lysates blocked NLRC4 S533 phosphorylation in vitro, and Prkcd(-/-) macrophages exhibited greatly attenuated caspase-1 activation and IL-1beta secretion specifically in response to S. typhimurium. Phosphorylation-defective NLRC4 S533A failed to recruit procaspase-1 and did not assemble inflammasome specks during S. typhimurium infection, so phosphorylation of NLRC4 S533 probably drives conformational changes necessary for NLRC4 inflammasome activity and host innate immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Qu, Yan -- Misaghi, Shahram -- Izrael-Tomasevic, Anita -- Newton, Kim -- Gilmour, Laurie L -- Lamkanfi, Mohamed -- Louie, Salina -- Kayagaki, Nobuhiko -- Liu, Jinfeng -- Komuves, Laszlo -- Cupp, James E -- Arnott, David -- Monack, Denise -- Dixit, Vishva M -- England -- Nature. 2012 Oct 25;490(7421):539-42. doi: 10.1038/nature11429.

    Increased HIV-1 vaccine efficacy against viruses with genetic signatures in Env V2 (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-09-11
    Description: The RV144 trial demonstrated 31% vaccine efficacy at preventing human immunodeficiency virus (HIV)-1 infection. Antibodies against the HIV-1 envelope variable loops 1 and 2 (Env V1 and V2) correlated inversely with infection risk. We proposed that vaccine-induced immune responses against V1/V2 would have a selective effect against, or sieve, HIV-1 breakthrough viruses. A total of 936 HIV-1 genome sequences from 44 vaccine and 66 placebo recipients were examined. We show that vaccine-induced immune responses were associated with two signatures in V2 at amino acid positions 169 and 181. Vaccine efficacy against viruses matching the vaccine at position 169 was 48% (confidence interval 18% to 66%; P = 0.0036), whereas vaccine efficacy against viruses mismatching the vaccine at position 181 was 78% (confidence interval 35% to 93%; P = 0.0028). Residue 169 is in a cationic glycosylated region recognized by broadly neutralizing and RV144-derived antibodies. The predicted distance between the two signature sites (21 +/- 7 A) and their match/mismatch dichotomy indicate that multiple factors may be involved in the protection observed in RV144. Genetic signatures of RV144 vaccination in V2 complement the finding of an association between high V1/V2-binding antibodies and reduced risk of HIV-1 acquisition, and provide evidence that vaccine-induced V2 responses plausibly had a role in the partial protection conferred by the RV144 regimen.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3551291/" 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/PMC3551291/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rolland, Morgane -- Edlefsen, Paul T -- Larsen, Brendan B -- Tovanabutra, Sodsai -- Sanders-Buell, Eric -- Hertz, Tomer -- deCamp, Allan C -- Carrico, Chris -- Menis, Sergey -- Magaret, Craig A -- Ahmed, Hasan -- Juraska, Michal -- Chen, Lennie -- Konopa, Philip -- Nariya, Snehal -- Stoddard, Julia N -- Wong, Kim -- Zhao, Hong -- Deng, Wenjie -- Maust, Brandon S -- Bose, Meera -- Howell, Shana -- Bates, Adam -- Lazzaro, Michelle -- O'Sullivan, Annemarie -- Lei, Esther -- Bradfield, Andrea -- Ibitamuno, Grace -- Assawadarachai, Vatcharain -- O'Connell, Robert J -- deSouza, Mark S -- Nitayaphan, Sorachai -- Rerks-Ngarm, Supachai -- Robb, Merlin L -- McLellan, Jason S -- Georgiev, Ivelin -- Kwong, Peter D -- Carlson, Jonathan M -- Michael, Nelson L -- Schief, William R -- Gilbert, Peter B -- Mullins, James I -- Kim, Jerome H -- 2R37AI05465-10/AI/NIAID NIH HHS/ -- K25 AI087397/AI/NIAID NIH HHS/ -- R01 AI054165/AI/NIAID NIH HHS/ -- R37 AI054165/AI/NIAID NIH HHS/ -- UM1 AI068635/AI/NIAID NIH HHS/ -- Y01 AI2642-12/AI/NIAID NIH HHS/ -- Y1-AI-2642-12/AI/NIAID NIH HHS/ -- England -- Nature. 2012 Oct 18;490(7420):417-20. doi: 10.1038/nature11519.
