    Rational HIV immunogen design to target specific germline B cell receptors (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-03-30
    Description: Vaccine development to induce broadly neutralizing antibodies (bNAbs) against HIV-1 is a global health priority. Potent VRC01-class bNAbs against the CD4 binding site of HIV gp120 have been isolated from HIV-1-infected individuals; however, such bNAbs have not been induced by vaccination. Wild-type gp120 proteins lack detectable affinity for predicted germline precursors of VRC01-class bNAbs, making them poor immunogens to prime a VRC01-class response. We employed computation-guided, in vitro screening to engineer a germline-targeting gp120 outer domain immunogen that binds to multiple VRC01-class bNAbs and germline precursors, and elucidated germline binding crystallographically. When multimerized on nanoparticles, this immunogen (eOD-GT6) activates germline and mature VRC01-class B cells. Thus, eOD-GT6 nanoparticles have promise as a vaccine prime. In principle, germline-targeting strategies could be applied to other epitopes and pathogens.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3689846/" 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/PMC3689846/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jardine, Joseph -- Julien, Jean-Philippe -- Menis, Sergey -- Ota, Takayuki -- Kalyuzhniy, Oleksandr -- McGuire, Andrew -- Sok, Devin -- Huang, Po-Ssu -- MacPherson, Skye -- Jones, Meaghan -- Nieusma, Travis -- Mathison, John -- Baker, David -- Ward, Andrew B -- Burton, Dennis R -- Stamatatos, Leonidas -- Nemazee, David -- Wilson, Ian A -- Schief, William R -- 5T32AI007606-10/AI/NIAID NIH HHS/ -- AI081625/AI/NIAID NIH HHS/ -- AI33292/AI/NIAID NIH HHS/ -- AI84817/AI/NIAID NIH HHS/ -- P01 AI094419/AI/NIAID NIH HHS/ -- P30 AI027767-24/AI/NIAID NIH HHS/ -- P41RR001209/RR/NCRR NIH HHS/ -- R01 AI033292/AI/NIAID NIH HHS/ -- R01 AI073148/AI/NIAID NIH HHS/ -- R01 AI081625/AI/NIAID NIH HHS/ -- R01 AI084817/AI/NIAID NIH HHS/ -- R37 AI033292/AI/NIAID NIH HHS/ -- T32 CA080416/CA/NCI NIH HHS/ -- T32CA080416/CA/NCI NIH HHS/ -- UM1 AI100663/AI/NIAID NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2013 May 10;340(6133):711-6. doi: 10.1126/science.1234150.

    The intestinal microbiota modulates the anticancer immune effects of cyclophosphamide (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-11-23
    Description: Cyclophosphamide is one of several clinically important cancer drugs whose therapeutic efficacy is due in part to their ability to stimulate antitumor immune responses. Studying mouse models, we demonstrate that cyclophosphamide alters the composition of microbiota in the small intestine and induces the translocation of selected species of Gram-positive bacteria into secondary lymphoid organs. There, these bacteria stimulate the generation of a specific subset of "pathogenic" T helper 17 (pT(H)17) cells and memory T(H)1 immune responses. Tumor-bearing mice that were germ-free or that had been treated with antibiotics to kill Gram-positive bacteria showed a reduction in pT(H)17 responses, and their tumors were resistant to cyclophosphamide. Adoptive transfer of pT(H)17 cells partially restored the antitumor efficacy of cyclophosphamide. These results suggest that the gut microbiota help shape the anticancer immune response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4048947/" 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/PMC4048947/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Viaud, Sophie -- Saccheri, Fabiana -- Mignot, Gregoire -- Yamazaki, Takahiro -- Daillere, Romain -- Hannani, Dalil -- Enot, David P -- Pfirschke, Christina -- Engblom, Camilla -- Pittet, Mikael J -- Schlitzer, Andreas -- Ginhoux, Florent -- Apetoh, Lionel -- Chachaty, Elisabeth -- Woerther, Paul-Louis -- Eberl, Gerard -- Berard, Marion -- Ecobichon, Chantal -- Clermont, Dominique -- Bizet, Chantal -- Gaboriau-Routhiau, Valerie -- Cerf-Bensussan, Nadine -- Opolon, Paule -- Yessaad, Nadia -- Vivier, Eric -- Ryffel, Bernhard -- Elson, Charles O -- Dore, Joel -- Kroemer, Guido -- Lepage, Patricia -- Boneca, Ivo Gomperts -- Ghiringhelli, Francois -- Zitvogel, Laurence -- P01 DK071176/DK/NIDDK NIH HHS/ -- P01DK071176/DK/NIDDK NIH HHS/ -- P50 CA086355/CA/NCI NIH HHS/ -- R01 AI084880/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Nov 22;342(6161):971-6. doi: 10.1126/science.1240537.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Sante et de la Recherche Medicale, U1015, Equipe labellisee Ligue Nationale Contre le Cancer, Institut Gustave Roussy, Villejuif, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24264990" target="_blank"〉PubMed〈/a〉

    Circadian clock NAD+ cycle drives mitochondrial oxidative metabolism in mice (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-09-21
    Description: Circadian clocks are self-sustained cellular oscillators that synchronize oxidative and reductive cycles in anticipation of the solar cycle. We found that the clock transcription feedback loop produces cycles of nicotinamide adenine dinucleotide (NAD(+)) biosynthesis, adenosine triphosphate production, and mitochondrial respiration through modulation of mitochondrial protein acetylation to synchronize oxidative metabolic pathways with the 24-hour fasting and feeding cycle. Circadian control of the activity of the NAD(+)-dependent deacetylase sirtuin 3 (SIRT3) generated rhythms in the acetylation and activity of oxidative enzymes and respiration in isolated mitochondria, and NAD(+) supplementation restored protein deacetylation and enhanced oxygen consumption in circadian mutant mice. Thus, circadian control of NAD(+) bioavailability modulates mitochondrial oxidative function and organismal metabolism across the daily cycles of fasting and feeding.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3963134/" 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/PMC3963134/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peek, Clara Bien -- Affinati, Alison H -- Ramsey, Kathryn Moynihan -- Kuo, Hsin-Yu -- Yu, Wei -- Sena, Laura A -- Ilkayeva, Olga -- Marcheva, Biliana -- Kobayashi, Yumiko -- Omura, Chiaki -- Levine, Daniel C -- Bacsik, David J -- Gius, David -- Newgard, Christopher B -- Goetzman, Eric -- Chandel, Navdeep S -- Denu, John M -- Mrksich, Milan -- Bass, Joseph -- 5P01HL071643-10/HL/NHLBI NIH HHS/ -- 5P30AR057216-05/AR/NIAMS NIH HHS/ -- F30 DK085936/DK/NIDDK NIH HHS/ -- F30 ES019815/ES/NIEHS NIH HHS/ -- F32 DK092034/DK/NIDDK NIH HHS/ -- P01 AG011412/AG/NIA NIH HHS/ -- P01AG011412-16/AG/NIA NIH HHS/ -- P01DK58398/DK/NIDDK NIH HHS/ -- P30 CA014520/CA/NCI NIH HHS/ -- R01 AG038679/AG/NIA NIH HHS/ -- R01 CA152601-01/CA/NCI NIH HHS/ -- R01 CA152799-01A1/CA/NCI NIH HHS/ -- R01 CA16383801A1/CA/NCI NIH HHS/ -- R01 CA168292/CA/NCI NIH HHS/ -- R01 CA168292-01A1/CA/NCI NIH HHS/ -- R01 DK090242/DK/NIDDK NIH HHS/ -- R01 DK090625/DK/NIDDK NIH HHS/ -- R01 GM065386/GM/NIGMS NIH HHS/ -- R01 HL097817/HL/NHLBI NIH HHS/ -- R01DK090242-03/DK/NIDDK NIH HHS/ -- R01DK090625-01A1/DK/NIDDK NIH HHS/ -- R01HL097817-01/HL/NHLBI NIH HHS/ -- R37 GM059785/GM/NIGMS NIH HHS/ -- T32 DK007169/DK/NIDDK NIH HHS/ -- T32 GM008152/GM/NIGMS NIH HHS/ -- T32 HL007909/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Nov 1;342(6158):1243417. doi: 10.1126/science.1243417.

    Circulating breast tumor cells exhibit dynamic changes in epithelial and mesenchymal composition (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-02-02
    Description: Epithelial-mesenchymal transition (EMT) of adherent epithelial cells to a migratory mesenchymal state has been implicated in tumor metastasis in preclinical models. To investigate its role in human cancer, we characterized EMT in circulating tumor cells (CTCs) from breast cancer patients. Rare primary tumor cells simultaneously expressed mesenchymal and epithelial markers, but mesenchymal cells were highly enriched in CTCs. Serial CTC monitoring in 11 patients suggested an association of mesenchymal CTCs with disease progression. In an index patient, reversible shifts between these cell fates accompanied each cycle of response to therapy and disease progression. Mesenchymal CTCs occurred as both single cells and multicellular clusters, expressing known EMT regulators, including transforming growth factor (TGF)-beta pathway components and the FOXC1 transcription factor. These data support a role for EMT in the blood-borne dissemination of human breast cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3760262/" 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/PMC3760262/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yu, Min -- Bardia, Aditya -- Wittner, Ben S -- Stott, Shannon L -- Smas, Malgorzata E -- Ting, David T -- Isakoff, Steven J -- Ciciliano, Jordan C -- Wells, Marissa N -- Shah, Ajay M -- Concannon, Kyle F -- Donaldson, Maria C -- Sequist, Lecia V -- Brachtel, Elena -- Sgroi, Dennis -- Baselga, Jose -- Ramaswamy, Sridhar -- Toner, Mehmet -- Haber, Daniel A -- Maheswaran, Shyamala -- EB008047/EB/NIBIB NIH HHS/ -- K12 CA087723/CA/NCI NIH HHS/ -- NCI CA129933/CA/NCI NIH HHS/ -- R01 CA129933/CA/NCI NIH HHS/ -- U01 EB012493/EB/NIBIB NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Feb 1;339(6119):580-4. doi: 10.1126/science.1228522.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts General Hospital Cancer Center, Harvard Medical School, Charlestown, MA 02129, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23372014" target="_blank"〉PubMed〈/a〉

    Minimal "Self" peptides that inhibit phagocytic clearance and enhance delivery of nanoparticles (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-02-23
    Description: Foreign particles and cells are cleared from the body by phagocytes that must also recognize and avoid clearance of "self" cells. The membrane protein CD47 is reportedly a "marker of self" in mice that impedes phagocytosis of self by signaling through the phagocyte receptor CD172a. Minimal "Self" peptides were computationally designed from human CD47 and then synthesized and attached to virus-size particles for intravenous injection into mice that express a CD172a variant compatible with hCD47. Self peptides delay macrophage-mediated clearance of nanoparticles, which promotes persistent circulation that enhances dye and drug delivery to tumors. Self-peptide affinity for CD172a is near the optimum measured for human CD172a variants, and Self peptide also potently inhibits nanoparticle uptake mediated by the contractile cytoskeleton. The reductionist approach reveals the importance of human Self peptides and their utility in enhancing drug delivery and imaging.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3966479/" 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/PMC3966479/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rodriguez, Pia L -- Harada, Takamasa -- Christian, David A -- Pantano, Diego A -- Tsai, Richard K -- Discher, Dennis E -- 8UL1TR000003/TR/NCATS NIH HHS/ -- P01-DK032094/DK/NIDDK NIH HHS/ -- P30-DK090969/DK/NIDDK NIH HHS/ -- R01 EB007049/EB/NIBIB NIH HHS/ -- R01 HL062352/HL/NHLBI NIH HHS/ -- R01-EB007049/EB/NIBIB NIH HHS/ -- R01-HL062352/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2013 Feb 22;339(6122):971-5. doi: 10.1126/science.1229568.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular and Cell Biophysics and NanoBioPolymers Laboratory, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23430657" target="_blank"〉PubMed〈/a〉

    A switch between topological domains underlies HoxD genes collinearity in mouse limbs (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-06-08
    Description: Hox genes are major determinants of the animal body plan, where they organize structures along both the trunk and appendicular axes. During mouse limb development, Hoxd genes are transcribed in two waves: early on, when the arm and forearm are specified, and later, when digits form. The transition between early and late regulations involves a functional switch between two opposite topological domains. This switch is reflected by a subset of Hoxd genes mapping centrally into the cluster, which initially interact with the telomeric domain and subsequently swing toward the centromeric domain, where they establish new contacts. This transition between independent regulatory landscapes illustrates both the modularity of the limbs and the distinct evolutionary histories of its various pieces. It also allows the formation of an intermediate area of low HOX proteins content, which develops into the wrist, the transition between our arms and our hands. This regulatory strategy accounts for collinear Hox gene regulation in land vertebrate appendages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andrey, Guillaume -- Montavon, Thomas -- Mascrez, Benedicte -- Gonzalez, Federico -- Noordermeer, Daan -- Leleu, Marion -- Trono, Didier -- Spitz, Francois -- Duboule, Denis -- New York, N.Y. -- Science. 2013 Jun 7;340(6137):1234167. doi: 10.1126/science.1234167.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Life Sciences, Federal Institute of Technology, Lausanne, 1015 Lausanne, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23744951" target="_blank"〉PubMed〈/a〉

    Nuclear lamin-A scales with tissue stiffness and enhances matrix-directed differentiation (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-08-31
    Description: Tissues can be soft like fat, which bears little stress, or stiff like bone, which sustains high stress, but whether there is a systematic relationship between tissue mechanics and differentiation is unknown. Here, proteomics analyses revealed that levels of the nucleoskeletal protein lamin-A scaled with tissue elasticity, E, as did levels of collagens in the extracellular matrix that determine E. Stem cell differentiation into fat on soft matrix was enhanced by low lamin-A levels, whereas differentiation into bone on stiff matrix was enhanced by high lamin-A levels. Matrix stiffness directly influenced lamin-A protein levels, and, although lamin-A transcription was regulated by the vitamin A/retinoic acid (RA) pathway with broad roles in development, nuclear entry of RA receptors was modulated by lamin-A protein. Tissue stiffness and stress thus increase lamin-A levels, which stabilize the nucleus while also contributing to lineage determination.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3976548/" 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/PMC3976548/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Swift, Joe -- Ivanovska, Irena L -- Buxboim, Amnon -- Harada, Takamasa -- Dingal, P C Dave P -- Pinter, Joel -- Pajerowski, J David -- Spinler, Kyle R -- Shin, Jae-Won -- Tewari, Manorama -- Rehfeldt, Florian -- Speicher, David W -- Discher, Dennis E -- 8UL1TR000003/TR/NCATS NIH HHS/ -- CA010815/CA/NCI NIH HHS/ -- HL038794/HL/NHLBI NIH HHS/ -- P01DK032094/DK/NIDDK NIH HHS/ -- P30-DK090969/DK/NIDDK NIH HHS/ -- R01 EB007049/EB/NIBIB NIH HHS/ -- R01 HL062352/HL/NHLBI NIH HHS/ -- R01EB007049/EB/NIBIB NIH HHS/ -- R01HL062352/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2013 Aug 30;341(6149):1240104. doi: 10.1126/science.1240104.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular and Cell Biophysics Laboratory, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23990565" target="_blank"〉PubMed〈/a〉

Despite its efficacy and widespread use in more than 600 million people, the mechanisms by which it stimulates protective immunity remain poorly understood. Recent studies using systems biology approaches in humans have revealed that YF-17D-induced early expression of general control nonderepressible 2 kinase (GCN2) in the blood strongly correlates with the magnitude of the later CD8(+) T cell response. We demonstrate a key role for virus-induced GCN2 activation in programming dendritic cells to initiate autophagy and enhanced antigen presentation to both CD4(+) and CD8(+) T cells. These results reveal an unappreciated link between virus-induced integrated stress response in dendritic cells and the adaptive immune response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4048998/" 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/PMC4048998/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ravindran, Rajesh -- Khan, Nooruddin -- Nakaya, Helder I -- Li, Shuzhao -- Loebbermann, Jens -- Maddur, Mohan S -- Park, Youngja -- Jones, Dean P -- Chappert, Pascal -- Davoust, Jean -- Weiss, David S -- Virgin, Herbert W -- Ron, David -- Pulendran, Bali -- 084812/Wellcome Trust/United Kingdom -- 084812/Z/08/Z/Wellcome Trust/United Kingdom -- N01 AI50019/AI/NIAID NIH HHS/ -- N01 AI50025/AI/NIAID NIH HHS/ -- P51 OD011132/OD/NIH HHS/ -- R37 AI048638/AI/NIAID NIH HHS/ -- R37 DK057665/DK/NIDDK NIH HHS/ -- R56 AI048638/AI/NIAID NIH HHS/ -- U19 AI057266/AI/NIAID NIH HHS/ -- U19 AI090023/AI/NIAID NIH HHS/ -- U54 AI057157/AI/NIAID NIH HHS/ -- U54 AI057160/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Jan 17;343(6168):313-7. doi: 10.1126/science.1246829.

    Pivotal roles of cGAS-cGAMP signaling in antiviral defense and immune adjuvant effects (2013)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 2013-08-31
    Description: Invasion of microbial DNA into the cytoplasm of animal cells triggers a cascade of host immune reactions that help clear the infection; however, self DNA in the cytoplasm can cause autoimmune diseases. Biochemical approaches led to the identification of cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) synthase (cGAS) as a cytosolic DNA sensor that triggers innate immune responses. Here, we show that cells from cGAS-deficient (cGas(-/-)) mice, including fibroblasts, macrophages, and dendritic cells, failed to produce type I interferons and other cytokines in response to DNA transfection or DNA virus infection. cGas(-/-) mice were more susceptible to lethal infection with herpes simplex virus 1 (HSV1) than wild-type mice. We also show that cGAMP is an adjuvant that boosts antigen-specific T cell activation and antibody production in mice.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3863637/" 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/PMC3863637/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Xiao-Dong -- Wu, Jiaxi -- Gao, Daxing -- Wang, Hua -- Sun, Lijun -- Chen, Zhijian J -- 5T32AI070116/AI/NIAID NIH HHS/ -- AI-093967/AI/NIAID NIH HHS/ -- R01 AI093967/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1390-4. doi: 10.1126/science.1244040.

    A long noncoding RNA mediates both activation and repression of immune response genes (2013)

    Description: An inducible program of inflammatory gene expression is central to antimicrobial defenses. This response is controlled by a collaboration involving signal-dependent activation of transcription factors, transcriptional co-regulators, and chromatin-modifying factors. We have identified a long noncoding RNA (lncRNA) that acts as a key regulator of this inflammatory response. Pattern recognition receptors such as the Toll-like receptors induce the expression of numerous lncRNAs. One of these, lincRNA-Cox2, mediates both the activation and repression of distinct classes of immune genes. Transcriptional repression of target genes is dependent on interactions of lincRNA-Cox2 with heterogeneous nuclear ribonucleoprotein A/B and A2/B1. Collectively, these studies unveil a central role of lincRNA-Cox2 as a broad-acting regulatory component of the circuit that controls the inflammatory response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4376668/" 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/PMC4376668/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carpenter, Susan -- Aiello, Daniel -- Atianand, Maninjay K -- Ricci, Emiliano P -- Gandhi, Pallavi -- Hall, Lisa L -- Byron, Meg -- Monks, Brian -- Henry-Bezy, Meabh -- Lawrence, Jeanne B -- O'Neill, Luke A J -- Moore, Melissa J -- Caffrey, Daniel R -- Fitzgerald, Katherine A -- AI067497/AI/NIAID NIH HHS/ -- GM053234/GM/NIGMS NIH HHS/ -- R01 AI067497/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Aug 16;341(6147):789-92. doi: 10.1126/science.1240925.
