    Molecular basis of T cell inactivation by CTLA-4 (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-12-18
    Description: CTLA-4, a negative regulator of T cell function, was found to associate with the T cell receptor (TCR) complex zeta chain in primary T cells. The association of TCRzeta with CTLA-4, reconstituted in 293 transfectants, was enhanced by p56(lck)-induced tyrosine phosphorylation. Coexpression of the CTLA-4-associated tyrosine phosphatase, SHP-2, resulted in dephosphorylation of TCRzeta bound to CTLA-4 and abolished the p56(lck)-inducible TCRzeta-CTLA-4 interaction. Thus, CTLA-4 inhibits TCR signal transduction by binding to TCRzeta and inhibiting tyrosine phosphorylation after T cell activation. These findings have broad implications for the negative regulation of T cell function and T cell tolerance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, K M -- Chuang, E -- Griffin, M -- Khattri, R -- Hong, D K -- Zhang, W -- Straus, D -- Samelson, L E -- Thompson, C B -- Bluestone, J A -- P01 AI35294-6/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1998 Dec 18;282(5397):2263-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ben May Institute for Cancer Research, and Committee on Immunology, University of Chicago, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9856951" target="_blank"〉PubMed〈/a〉

    Innate immunity and intestinal microbiota in the development of Type 1 diabetes (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-09-23
    Description: Type 1 diabetes (T1D) is a debilitating autoimmune disease that results from T-cell-mediated destruction of insulin-producing beta-cells. Its incidence has increased during the past several decades in developed countries, suggesting that changes in the environment (including the human microbial environment) may influence disease pathogenesis. The incidence of spontaneous T1D in non-obese diabetic (NOD) mice can be affected by the microbial environment in the animal housing facility or by exposure to microbial stimuli, such as injection with mycobacteria or various microbial products. Here we show that specific pathogen-free NOD mice lacking MyD88 protein (an adaptor for multiple innate immune receptors that recognize microbial stimuli) do not develop T1D. The effect is dependent on commensal microbes because germ-free MyD88-negative NOD mice develop robust diabetes, whereas colonization of these germ-free MyD88-negative NOD mice with a defined microbial consortium (representing bacterial phyla normally present in human gut) attenuates T1D. We also find that MyD88 deficiency changes the composition of the distal gut microbiota, and that exposure to the microbiota of specific pathogen-free MyD88-negative NOD donors attenuates T1D in germ-free NOD recipients. Together, these findings indicate that interaction of the intestinal microbes with the innate immune system is a critical epigenetic factor modifying T1D predisposition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2574766/" 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/PMC2574766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wen, Li -- Ley, Ruth E -- Volchkov, Pavel Yu -- Stranges, Peter B -- Avanesyan, Lia -- Stonebraker, Austin C -- Hu, Changyun -- Wong, F Susan -- Szot, Gregory L -- Bluestone, Jeffrey A -- Gordon, Jeffrey I -- Chervonsky, Alexander V -- DK063452/DK/NIDDK NIH HHS/ -- DK30292/DK/NIDDK NIH HHS/ -- DK42086/DK/NIDDK NIH HHS/ -- DK45735/DK/NIDDK NIH HHS/ -- DK70977/DK/NIDDK NIH HHS/ -- P30 DK042086/DK/NIDDK NIH HHS/ -- P30 DK042086-16/DK/NIDDK NIH HHS/ -- P30 DK045735/DK/NIDDK NIH HHS/ -- P30 DK045735-10/DK/NIDDK NIH HHS/ -- P30 DK045735-119006/DK/NIDDK NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- P30 DK056341-07/DK/NIDDK NIH HHS/ -- P30 DK056341-08/DK/NIDDK NIH HHS/ -- P30 DK063720/DK/NIDDK NIH HHS/ -- P30 DK063720-01/DK/NIDDK NIH HHS/ -- P30 DK63720/DK/NIDDK NIH HHS/ -- R01 DK030292/DK/NIDDK NIH HHS/ -- R01 DK030292-24/DK/NIDDK NIH HHS/ -- R01 DK070977/DK/NIDDK NIH HHS/ -- R01 DK070977-04/DK/NIDDK NIH HHS/ -- R21 DK063452/DK/NIDDK NIH HHS/ -- R21 DK063452-02/DK/NIDDK NIH HHS/ -- R37 AI046643/AI/NIAID NIH HHS/ -- R37 AI046643-10/AI/NIAID NIH HHS/ -- R37 AI46643/AI/NIAID NIH HHS/ -- England -- Nature. 2008 Oct 23;455(7216):1109-13. doi: 10.1038/nature07336.

    Genetics, pathogenesis and clinical interventions in type 1 diabetes (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-05-01
    Description: Type 1 diabetes is an autoimmune disorder afflicting millions of people worldwide. Once diagnosed, patients require lifelong insulin treatment and can experience numerous disease-associated complications. The last decade has seen tremendous advances in elucidating the causes and treatment of the disease based on extensive research both in rodent models of spontaneous diabetes and in humans. Integrating these advances has led to the recognition that the balance between regulatory and effector T cells determines disease risk, timing of disease activation, and disease tempo. Here we describe current progress, the challenges ahead and the new interventions that are being tested to address the unmet need for preventative or curative therapies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bluestone, Jeffrey A -- Herold, Kevan -- Eisenbarth, George -- England -- Nature. 2010 Apr 29;464(7293):1293-300.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Diabetes Center and the Department of Medicine, University of California, San Francisco, San Francisco, California 94143, USA. jbluest@diabetes.ucsf.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20432533" target="_blank"〉PubMed〈/a〉

    Structure and specificity of a class II MHC alloreactive gamma delta T cell receptor heterodimer (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-08-18
    Description: Two distinct CD3-associated T cell receptors (TCR alpha beta and TCR gamma delta) are expressed in a mutually exclusive fashion on separate subsets of T lymphocytes. While the specificity of the TCR alpha beta repertoire for major histocompatibility complex (MHC) antigens is well established, the diversity of expressed gamma delta receptors and the ligands they recognize are less well understood. An alloreactive CD3+CD4-CD8- T cell line specific for murine class II MHC (Ia) antigens encoded in the I-E subregion of the H-2 gene complex was identified, and the primary structure of its gamma delta receptor heterodimer was characterized. In contrast to a TCR alpha beta-expressing alloreactive T cell line selected for similar specificity, the TCR gamma delta line displayed broad cross-reactivity for multiple distinct I-E-encoded allogeneic Ia molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matis, L A -- Fry, A M -- Cron, R Q -- Cotterman, M M -- Dick, R F -- Bluestone, J A -- 5-T32AI07090-10/AI/NIAID NIH HHS/ -- CA-14599-15/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1989 Aug 18;245(4919):746-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biochemistry and Biophysics, Food and Drug Administration, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2528206" target="_blank"〉PubMed〈/a〉

    Requirement for positive selection of gamma delta receptor-bearing T cells (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-08-23
    Description: The alpha beta and gamma delta T cell receptors for antigen (TCR) delineate distinct T cell populations. TCR alpha beta-bearing thymocytes must be positively selected by binding of the TCR to major histocompatibility complex (MHC) molecules on thymic epithelium. To examine the requirement for positive selection of TCR gamma delta T cells, mice bearing a class I MHC-specific gamma delta transgene (Tg) were crossed to mice with disrupted beta 2 microglobulin (beta 2M) genes. The Tg+beta 2M- (class I MHC-) offspring had Tg+ thymocytes that did not proliferate to antigen or Tg-specific monoclonal antibody and few peripheral Tg+ cells. This is evidence for positive selection within the gamma delta T cell subset.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wells, F B -- Gahm, S J -- Hedrick, S M -- Bluestone, J A -- Dent, A -- Matis, L A -- AI 26847-03/AI/NIAID NIH HHS/ -- AI00602/AI/NIAID NIH HHS/ -- N01-C0-74102/PHS HHS/ -- New York, N.Y. -- Science. 1991 Aug 23;253(5022):903-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biological Carcinogenesis and Development Program, Program Resources, Inc./DynCorp, NCI-Frederick Cancer Research and Development Center, MD 21701-0201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1831565" target="_blank"〉PubMed〈/a〉

    Control of TH17 cells occurs in the small intestine (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-07-19
    Description: Interleukin (IL)-17-producing T helper cells (T(H)17) are a recently identified CD4(+) T cell subset distinct from T helper type 1 (T(H)1) and T helper type 2 (T(H)2) cells. T(H)17 cells can drive antigen-specific autoimmune diseases and are considered the main population of pathogenic T cells driving experimental autoimmune encephalomyelitis (EAE), the mouse model for multiple sclerosis. The factors that are needed for the generation of T(H)17 cells have been well characterized. However, where and how the immune system controls T(H)17 cells in vivo remains unclear. Here, by using a model of tolerance induced by CD3-specific antibody, a model of sepsis and influenza A viral infection (H1N1), we show that pro-inflammatory T(H)17 cells can be redirected to and controlled in the small intestine. T(H)17-specific IL-17A secretion induced expression of the chemokine CCL20 in the small intestine, facilitating the migration of these cells specifically to the small intestine via the CCR6/CCL20 axis. Moreover, we found that T(H)17 cells are controlled by two different mechanisms in the small intestine: first, they are eliminated via the intestinal lumen; second, pro-inflammatory T(H)17 cells simultaneously acquire a regulatory phenotype with in vitro and in vivo immune-suppressive properties (rT(H)17). These results identify mechanisms limiting T(H)17 cell pathogenicity and implicate the gastrointestinal tract as a site for control of T(H)17 cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3148838/" 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/PMC3148838/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Esplugues, Enric -- Huber, Samuel -- Gagliani, Nicola -- Hauser, Anja E -- Town, Terrence -- Wan, Yisong Y -- O'Connor, William Jr -- Rongvaux, Anthony -- Van Rooijen, Nico -- Haberman, Ann M -- Iwakura, Yoichiro -- Kuchroo, Vijay K -- Kolls, Jay K -- Bluestone, Jeffrey A -- Herold, Kevan C -- Flavell, Richard A -- DK45735/DK/NIDDK NIH HHS/ -- P30 DK045735/DK/NIDDK NIH HHS/ -- P30 DK045735-20/DK/NIDDK NIH HHS/ -- R01 HL061271/HL/NHLBI NIH HHS/ -- R01 HL062052/HL/NHLBI NIH HHS/ -- R21 HL104601/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Jul 17;475(7357):514-8. doi: 10.1038/nature10228.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunobiology, Yale University School of Medicine, New Haven, Connecticut 06520, USA. enric.esplugues@yale.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21765430" target="_blank"〉PubMed〈/a〉

    Long-term survival of xenogeneic pancreatic islet grafts induced by CTLA4lg (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-08-07
    Description: Antigen-specific T cell activation depends on T cell receptor-ligand interaction and costimulatory signals generated when accessory molecules bind to their ligands, such as CD28 to the B7 (also called BB1) molecule. A soluble fusion protein of human CTLA-4 (a protein homologous to CD28) and the immunoglobulin (lg) G1 Fc region (CTLA4lg) binds to human and murine B7 with high avidity and blocks T cell activation in vitro. CTLA4lg therapy blocked human pancreatic islet rejection in mice by directly affecting T cell recognition of B7+ antigen-presenting cells. In addition, CTLA4lg induced long-term, donor-specific tolerance, which may have applications to human organ transplantation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lenschow, D J -- Zeng, Y -- Thistlethwaite, J R -- Montag, A -- Brady, W -- Gibson, M G -- Linsley, P S -- Bluestone, J A -- AI29531/AI/NIAID NIH HHS/ -- R29 DK40092/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1992 Aug 7;257(5071):789-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ben May Institute, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1323143" target="_blank"〉PubMed〈/a〉

    In vivo administration of anti-CD3 prevents malignant progressor tumor growth (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-10-28
    Description: Malignant progressor tumors are only weakly immunogenic and can evade host recognition and rejection. One approach to therapy involves activation of the host antitumor cellular effector mechanisms. Since monoclonal antibodies to CD3 (anti-CD3) can activate T cells in vitro, an attempt was made to determine if tumor immunity could be achieved by the administration of anti-CD3 in vivo. T lymphocytes from mice injected with anti-CD3 showed increased interleukin-2 receptor (IL-2R) expression, increased proliferation to recombinant IL-2 (rIL-2), and enhanced reactivity in both an allogeneic mixed lymphocyte reaction and a mixed lymphocyte tumor culture. Malignant tumor growth in treated mice was also examined. The anti-CD3 treatment prevented tumor outgrowth that would have killed untreated animals and also stimulated an in vivo response against a malignant progressor tumor providing lasting tumor immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ellenhorn, J D -- Hirsch, R -- Schreiber, H -- Bluestone, J A -- New York, N.Y. -- Science. 1988 Oct 28;242(4878):569-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2902689" target="_blank"〉PubMed〈/a〉

    Characterization of T cell receptor gamma chain expression in a subset of murine thymocytes (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-12-12
    Description: While much information exists about the structure and function of the clonally distributed T cell receptor (TCR) alpha beta heterodimer, little is known about the gamma protein, the product of a third rearranging TCR gene. An antiserum to a carboxyl-terminal peptide common to several of the murine gamma chain constant regions and a monoclonal antibody to the murine T3 complex were used to identify products of this TCR gene family in a subpopulation of Lyt2-, L3T4- thymocytes. This subpopulation does not express TCR alpha or full-length TCR beta messenger RNA. The gamma chain is a 35-kilodalton (kD) protein that is disulfide-bonded to a 45-kD partner and is associated with the T3 complex. Analysis of the glycosylation pattern of this thymic gamma chain revealed that the major variable region gamma (V gamma) gene transcribed in activated peripheral T cells is absent from this subpopulation. The cells that bear this second T cell receptor may therefore represent a distinct lineage differentiating within the thymus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lew, A M -- Pardoll, D M -- Maloy, W L -- Fowlkes, B J -- Kruisbeek, A -- Cheng, S F -- Germain, R N -- Bluestone, J A -- Schwartz, R H -- Coligan, J E -- New York, N.Y. -- Science. 1986 Dec 12;234(4782):1401-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3787252" target="_blank"〉PubMed〈/a〉

This transgenic mouse expressed SLA antigen on its cell surfaces and transmitted the gene to offspring, in which the gene is also expressed. Skin grafts of such transgenic mice were rejected by normal C57BL/10 mice, suggesting that the foreign SLA antigen expressed in the transgenic mice is recognized as a functional transplantation antigen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frels, W I -- Bluestone, J A -- Hodes, R J -- Capecchi, M R -- Singer, D S -- GM 07825/GM/NIGMS NIH HHS/ -- GM 2116B/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 May 3;228(4699):577-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3885396" target="_blank"〉PubMed〈/a〉
