    Neutrophils scan for activated platelets to initiate inflammation (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-12-06
    Description: Immune and inflammatory responses require leukocytes to migrate within and through the vasculature, a process that is facilitated by their capacity to switch to a polarized morphology with an asymmetric distribution of receptors. We report that neutrophil polarization within activated venules served to organize a protruding domain that engaged activated platelets present in the bloodstream. The selectin ligand PSGL-1 transduced signals emanating from these interactions, resulting in the redistribution of receptors that drive neutrophil migration. Consequently, neutrophils unable to polarize or to transduce signals through PSGL-1 displayed aberrant crawling, and blockade of this domain protected mice against thromboinflammatory injury. These results reveal that recruited neutrophils scan for activated platelets, and they suggest that the neutrophils' bipolarity allows the integration of signals present at both the endothelium and the circulation before inflammation proceeds.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4280847/" 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/PMC4280847/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sreeramkumar, Vinatha -- Adrover, Jose M -- Ballesteros, Ivan -- Cuartero, Maria Isabel -- Rossaint, Jan -- Bilbao, Izaskun -- Nacher, Maria -- Pitaval, Christophe -- Radovanovic, Irena -- Fukui, Yoshinori -- McEver, Rodger P -- Filippi, Marie-Dominique -- Lizasoain, Ignacio -- Ruiz-Cabello, Jesus -- Zarbock, Alexander -- Moro, Maria A -- Hidalgo, Andres -- HL03463/HL/NHLBI NIH HHS/ -- HL085607/HL/NHLBI NIH HHS/ -- HL090676/HL/NHLBI NIH HHS/ -- P01 HL085607/HL/NHLBI NIH HHS/ -- R01 HL034363/HL/NHLBI NIH HHS/ -- R01 HL090676/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 5;346(6214):1234-8. doi: 10.1126/science.1256478.

    Gut microbiomes of Malawian twin pairs discordant for kwashiorkor (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-02-01
    Description: Kwashiorkor, an enigmatic form of severe acute malnutrition, is the consequence of inadequate nutrient intake plus additional environmental insults. To investigate the role of the gut microbiome, we studied 317 Malawian twin pairs during the first 3 years of life. During this time, half of the twin pairs remained well nourished, whereas 43% became discordant, and 7% manifested concordance for acute malnutrition. Both children in twin pairs discordant for kwashiorkor were treated with a peanut-based, ready-to-use therapeutic food (RUTF). Time-series metagenomic studies revealed that RUTF produced a transient maturation of metabolic functions in kwashiorkor gut microbiomes that regressed when administration of RUTF was stopped. Previously frozen fecal communities from several discordant pairs were each transplanted into gnotobiotic mice. The combination of Malawian diet and kwashiorkor microbiome produced marked weight loss in recipient mice, accompanied by perturbations in amino acid, carbohydrate, and intermediary metabolism that were only transiently ameliorated with RUTF. These findings implicate the gut microbiome as a causal factor in kwashiorkor.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3667500/" 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/PMC3667500/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, Michelle I -- Yatsunenko, Tanya -- Manary, Mark J -- Trehan, Indi -- Mkakosya, Rajhab -- Cheng, Jiye -- Kau, Andrew L -- Rich, Stephen S -- Concannon, Patrick -- Mychaleckyj, Josyf C -- Liu, Jie -- Houpt, Eric -- Li, Jia V -- Holmes, Elaine -- Nicholson, Jeremy -- Knights, Dan -- Ursell, Luke K -- Knight, Rob -- Gordon, Jeffrey I -- DK078669/DK/NIDDK NIH HHS/ -- DK30292/DK/NIDDK NIH HHS/ -- F32 DK091044/DK/NIDDK NIH HHS/ -- P01 DK078669/DK/NIDDK NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- R37 DK030292/DK/NIDDK NIH HHS/ -- T32 HD049338/HD/NICHD NIH HHS/ -- T32-HD049338/HD/NICHD NIH HHS/ -- T35 DK074375/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2013 Feb 1;339(6119):548-54. doi: 10.1126/science.1229000.

    Evolutionarily dynamic alternative splicing of GPR56 regulates regional cerebral cortical patterning (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-02-18
    Description: The human neocortex has numerous specialized functional areas whose formation is poorly understood. Here, we describe a 15-base pair deletion mutation in a regulatory element of GPR56 that selectively disrupts human cortex surrounding the Sylvian fissure bilaterally including "Broca's area," the primary language area, by disrupting regional GPR56 expression and blocking RFX transcription factor binding. GPR56 encodes a heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptor required for normal cortical development and is expressed in cortical progenitor cells. GPR56 expression levels regulate progenitor proliferation. GPR56 splice forms are highly variable between mice and humans, and the regulatory element of gyrencephalic mammals directs restricted lateral cortical expression. Our data reveal a mechanism by which control of GPR56 expression pattern by multiple alternative promoters can influence stem cell proliferation, gyral patterning, and, potentially, neocortex evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4480613/" 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/PMC4480613/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bae, Byoung-Il -- Tietjen, Ian -- Atabay, Kutay D -- Evrony, Gilad D -- Johnson, Matthew B -- Asare, Ebenezer -- Wang, Peter P -- Murayama, Ayako Y -- Im, Kiho -- Lisgo, Steven N -- Overman, Lynne -- Sestan, Nenad -- Chang, Bernard S -- Barkovich, A James -- Grant, P Ellen -- Topcu, Meral -- Politsky, Jeffrey -- Okano, Hideyuki -- Piao, Xianhua -- Walsh, Christopher A -- 2R01NS035129/NS/NINDS NIH HHS/ -- G0700089/Medical Research Council/United Kingdom -- GR082557/Wellcome Trust/United Kingdom -- HHSN275200900011C/PHS HHS/ -- N01-HD-9-0011/HD/NICHD NIH HHS/ -- R01 NS035129/NS/NINDS NIH HHS/ -- U01 MH081896/MH/NIMH NIH HHS/ -- U01MH081896/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Feb 14;343(6172):764-8. doi: 10.1126/science.1244392.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Genetics and Genomics, Manton Center for Orphan Disease, and Howard Hughes Medical Institute, Boston Children's Hospital, Broad Institute of MIT and Harvard, and Departments of Pediatrics and Neurology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24531968" target="_blank"〉PubMed〈/a〉

    Dysregulated humoral immunity to nontyphoidal Salmonella in HIV-infected African adults (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-04-24
    Description: Nontyphoidal Salmonellae are a major cause of life-threatening bacteremia among HIV-infected individuals. Although cell-mediated immunity controls intracellular infection, antibodies protect against Salmonella bacteremia. We report that high-titer antibodies specific for Salmonella lipopolysaccharide (LPS) are associated with a lack of Salmonella-killing in HIV-infected African adults. Killing was restored by genetically shortening LPS from the target Salmonella or removing LPS-specific antibodies from serum. Complement-mediated killing of Salmonella by healthy serum is shown to be induced specifically by antibodies against outer membrane proteins. This killing is lost when excess antibody against Salmonella LPS is added. Thus, our study indicates that impaired immunity against nontyphoidal Salmonella bacteremia in HIV infection results from excess inhibitory antibodies against Salmonella LPS, whereas serum killing of Salmonella is induced by antibodies against outer membrane proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3772309/" 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/PMC3772309/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacLennan, Calman A -- Gilchrist, James J -- Gordon, Melita A -- Cunningham, Adam F -- Cobbold, Mark -- Goodall, Margaret -- Kingsley, Robert A -- van Oosterhout, Joep J G -- Msefula, Chisomo L -- Mandala, Wilson L -- Leyton, Denisse L -- Marshall, Jennifer L -- Gondwe, Esther N -- Bobat, Saeeda -- Lopez-Macias, Constantino -- Doffinger, Rainer -- Henderson, Ian R -- Zijlstra, Eduard E -- Dougan, Gordon -- Drayson, Mark T -- MacLennan, Ian C M -- Molyneux, Malcolm E -- 067321/Wellcome Trust/United Kingdom -- BB/F022778/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0701275/Medical Research Council/United Kingdom -- G108/574/Medical Research Council/United Kingdom -- G8402371/Medical Research Council/United Kingdom -- G9818340/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Apr 23;328(5977):508-12. doi: 10.1126/science.1180346.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Centre for Immune Regulation and Clinical Immunology Service, Institute of Biomedical Research, School of Immunity and Infection, University of Birmingham, Birmingham, UK. c.maclennan@bham.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20413503" target="_blank"〉PubMed〈/a〉

    Cholinergic interneurons control local circuit activity and cocaine conditioning (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-12-18
    Description: Cholinergic neurons are widespread, and pharmacological modulation of acetylcholine receptors affects numerous brain processes, but such modulation entails side effects due to limitations in specificity for receptor type and target cell. As a result, causal roles of cholinergic neurons in circuits have been unclear. We integrated optogenetics, freely moving mammalian behavior, in vivo electrophysiology, and slice physiology to probe the cholinergic interneurons of the nucleus accumbens by direct excitation or inhibition. Despite representing less than 1% of local neurons, these cholinergic cells have dominant control roles, exerting powerful modulation of circuit activity. Furthermore, these neurons could be activated by cocaine, and silencing this drug-induced activity during cocaine exposure (despite the fact that the manipulation of the cholinergic interneurons was not aversive by itself) blocked cocaine conditioning in freely moving mammals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3142356/" 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/PMC3142356/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Witten, Ilana B -- Lin, Shih-Chun -- Brodsky, Matthew -- Prakash, Rohit -- Diester, Ilka -- Anikeeva, Polina -- Gradinaru, Viviana -- Ramakrishnan, Charu -- Deisseroth, Karl -- DP1 OD000616/OD/NIH HHS/ -- DP1 OD000616-01/OD/NIH HHS/ -- R01 DA020794/DA/NIDA NIH HHS/ -- R01 DA020794-01/DA/NIDA NIH HHS/ -- R01 MH075957/MH/NIMH NIH HHS/ -- R01 MH075957-01A2/MH/NIMH NIH HHS/ -- R01 MH086373/MH/NIMH NIH HHS/ -- R01 MH086373-01/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Dec 17;330(6011):1677-81. doi: 10.1126/science.1193771.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bioengineering, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21164015" target="_blank"〉PubMed〈/a〉

    The Hedgehog pathway promotes blood-brain barrier integrity and CNS immune quiescence (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-12-07
    Description: The blood-brain barrier (BBB) is composed of tightly bound endothelial cells (ECs) and perivascular astrocytes that regulate central nervous system (CNS) homeostasis. We showed that astrocytes secrete Sonic hedgehog and that BBB ECs express Hedgehog (Hh) receptors, which together promote BBB formation and integrity during embryonic development and adulthood. Using pharmacological inhibition and genetic inactivation of the Hh signaling pathway in ECs, we also demonstrated a critical role of the Hh pathway in promoting the immune quiescence of BBB ECs by decreasing the expression of proinflammatory mediators and the adhesion and migration of leukocytes, in vivo and in vitro. Overall, the Hh pathway provides a barrier-promoting effect and an endogenous anti-inflammatory balance to CNS-directed immune attacks, as occurs in multiple sclerosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alvarez, Jorge Ivan -- Dodelet-Devillers, Aurore -- Kebir, Hania -- Ifergan, Igal -- Fabre, Pierre J -- Terouz, Simone -- Sabbagh, Mike -- Wosik, Karolina -- Bourbonniere, Lyne -- Bernard, Monique -- van Horssen, Jack -- de Vries, Helga E -- Charron, Frederic -- Prat, Alexandre -- MOP74700/Canadian Institutes of Health Research/Canada -- MOP81880/Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2011 Dec 23;334(6063):1727-31. doi: 10.1126/science.1206936.

    Mutations in the RNA granule component TDRD7 cause cataract and glaucoma (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-03-26
    Description: The precise transcriptional regulation of gene expression is essential for vertebrate development, but the role of posttranscriptional regulatory mechanisms is less clear. Cytoplasmic RNA granules (RGs) function in the posttranscriptional control of gene expression, but the extent of RG involvement in organogenesis is unknown. We describe two human cases of pediatric cataract with loss-of-function mutations in TDRD7 and demonstrate that Tdrd7 nullizygosity in mouse causes cataracts, as well as glaucoma and an arrest in spermatogenesis. TDRD7 is a Tudor domain RNA binding protein that is expressed in lens fiber cells in distinct TDRD7-RGs that interact with STAU1-ribonucleoproteins (RNPs). TDRD7 coimmunoprecipitates with specific lens messenger RNAs (mRNAs) and is required for the posttranscriptional control of mRNAs that are critical to normal lens development and to RG function. These findings demonstrate a role for RGs in vertebrate organogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3279122/" 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/PMC3279122/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lachke, Salil A -- Alkuraya, Fowzan S -- Kneeland, Stephen C -- Ohn, Takbum -- Aboukhalil, Anton -- Howell, Gareth R -- Saadi, Irfan -- Cavallesco, Resy -- Yue, Yingzi -- Tsai, Anne C-H -- Nair, K Saidas -- Cosma, Mihai I -- Smith, Richard S -- Hodges, Emily -- Alfadhli, Suad M -- Al-Hajeri, Amal -- Shamseldin, Hanan E -- Behbehani, Abdulmutalib -- Hannon, Gregory J -- Bulyk, Martha L -- Drack, Arlene V -- Anderson, Paul J -- John, Simon W M -- Maas, Richard L -- P01 GM061354/GM/NIGMS NIH HHS/ -- P01 GM061354-07/GM/NIGMS NIH HHS/ -- R01 EY010123/EY/NEI NIH HHS/ -- R01 EY010123-15/EY/NEI NIH HHS/ -- R01 EY011721/EY/NEI NIH HHS/ -- R01 EY011721-15/EY/NEI NIH HHS/ -- R01 EY10123/EY/NEI NIH HHS/ -- R01 EY11721/EY/NEI NIH HHS/ -- R01 HD060050/HD/NICHD NIH HHS/ -- R01 HD060050-04/HD/NICHD NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Mar 25;331(6024):1571-6. doi: 10.1126/science.1195970.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Genetics, Department of Medicine, Brigham and Women's Hospital and Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21436445" target="_blank"〉PubMed〈/a〉

    Innate response activator B cells protect against microbial sepsis (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-17
    Description: Recognition and clearance of a bacterial infection are a fundamental properties of innate immunity. Here, we describe an effector B cell population that protects against microbial sepsis. Innate response activator (IRA) B cells are phenotypically and functionally distinct, develop and diverge from B1a B cells, depend on pattern-recognition receptors, and produce granulocyte-macrophage colony-stimulating factor. Specific deletion of IRA B cell activity impairs bacterial clearance, elicits a cytokine storm, and precipitates septic shock. These observations enrich our understanding of innate immunity, position IRA B cells as gatekeepers of bacterial infection, and identify new treatment avenues for infectious diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3279743/" 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/PMC3279743/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rauch, Philipp J -- Chudnovskiy, Aleksey -- Robbins, Clinton S -- Weber, Georg F -- Etzrodt, Martin -- Hilgendorf, Ingo -- Tiglao, Elizabeth -- Figueiredo, Jose-Luiz -- Iwamoto, Yoshiko -- Theurl, Igor -- Gorbatov, Rostic -- Waring, Michael T -- Chicoine, Adam T -- Mouded, Majd -- Pittet, Mikael J -- Nahrendorf, Matthias -- Weissleder, Ralph -- Swirski, Filip K -- 1R01HL095612/HL/NHLBI NIH HHS/ -- P01-A154904/PHS HHS/ -- P50 CA086355/CA/NCI NIH HHS/ -- P50 CA086355-11/CA/NCI NIH HHS/ -- P50 CA86355/CA/NCI NIH HHS/ -- R01 HL095612/HL/NHLBI NIH HHS/ -- R01 HL095612-03/HL/NHLBI NIH HHS/ -- R24 CA69246/CA/NCI NIH HHS/ -- S10 RR026360/RR/NCRR NIH HHS/ -- U01 HL080731/HL/NHLBI NIH HHS/ -- U01 HL080731-04/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2012 Feb 3;335(6068):597-601. doi: 10.1126/science.1215173.

    Interactions between commensal fungi and the C-type lectin receptor Dectin-1 influence colitis (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-08
    Description: The intestinal microflora, typically equated with bacteria, influences diseases such as obesity and inflammatory bowel disease. Here, we show that the mammalian gut contains a rich fungal community that interacts with the immune system through the innate immune receptor Dectin-1. Mice lacking Dectin-1 exhibited increased susceptibility to chemically induced colitis, which was the result of altered responses to indigenous fungi. In humans, we identified a polymorphism in the gene for Dectin-1 (CLEC7A) that is strongly linked to a severe form of ulcerative colitis. Together, our findings reveal a eukaryotic fungal community in the gut (the "mycobiome") that coexists with bacteria and substantially expands the repertoire of organisms interacting with the intestinal immune system to influence health and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3432565/" 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/PMC3432565/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iliev, Iliyan D -- Funari, Vincent A -- Taylor, Kent D -- Nguyen, Quoclinh -- Reyes, Christopher N -- Strom, Samuel P -- Brown, Jordan -- Becker, Courtney A -- Fleshner, Phillip R -- Dubinsky, Marla -- Rotter, Jerome I -- Wang, Hanlin L -- McGovern, Dermot P B -- Brown, Gordon D -- Underhill, David M -- 086558/Wellcome Trust/United Kingdom -- AI071116/AI/NIAID NIH HHS/ -- P01-DK046763/DK/NIDDK NIH HHS/ -- R01 DK093426/DK/NIDDK NIH HHS/ -- UL1 RR033176/RR/NCRR NIH HHS/ -- UL1 TR000124/TR/NCATS NIH HHS/ -- UL1RR033176/RR/NCRR NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Jun 8;336(6086):1314-7. doi: 10.1126/science.1221789.

    An immunosurveillance mechanism controls cancer cell ploidy (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-29
    Description: Cancer cells accommodate multiple genetic and epigenetic alterations that initially activate intrinsic (cell-autonomous) and extrinsic (immune-mediated) oncosuppressive mechanisms. Only once these barriers to oncogenesis have been overcome can malignant growth proceed unrestrained. Tetraploidization can contribute to oncogenesis because hyperploid cells are genomically unstable. We report that hyperploid cancer cells become immunogenic because of a constitutive endoplasmic reticulum stress response resulting in the aberrant cell surface exposure of calreticulin. Hyperploid, calreticulin-exposing cancer cells readily proliferated in immunodeficient mice and conserved their increased DNA content. In contrast, hyperploid cells injected into immunocompetent mice generated tumors only after a delay, and such tumors exhibited reduced DNA content, endoplasmic reticulum stress, and calreticulin exposure. Our results unveil an immunosurveillance system that imposes immunoselection against hyperploidy in carcinogen- and oncogene-induced cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Senovilla, Laura -- Vitale, Ilio -- Martins, Isabelle -- Tailler, Maximilien -- Pailleret, Claire -- Michaud, Mickael -- Galluzzi, Lorenzo -- Adjemian, Sandy -- Kepp, Oliver -- Niso-Santano, Mireia -- Shen, Shensi -- Marino, Guillermo -- Criollo, Alfredo -- Boileve, Alice -- Job, Bastien -- Ladoire, Sylvain -- Ghiringhelli, Francois -- Sistigu, Antonella -- Yamazaki, Takahiro -- Rello-Varona, Santiago -- Locher, Clara -- Poirier-Colame, Vichnou -- Talbot, Monique -- Valent, Alexander -- Berardinelli, Francesco -- Antoccia, Antonio -- Ciccosanti, Fabiola -- Fimia, Gian Maria -- Piacentini, Mauro -- Fueyo, Antonio -- Messina, Nicole L -- Li, Ming -- Chan, Christopher J -- Sigl, Verena -- Pourcher, Guillaume -- Ruckenstuhl, Christoph -- Carmona-Gutierrez, Didac -- Lazar, Vladimir -- Penninger, Josef M -- Madeo, Frank -- Lopez-Otin, Carlos -- Smyth, Mark J -- Zitvogel, Laurence -- Castedo, Maria -- Kroemer, Guido -- New York, N.Y. -- Science. 2012 Sep 28;337(6102):1678-84.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM, U848, Villejuif, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23019653" target="_blank"〉PubMed〈/a〉
