    Regulation of lymphokine messenger RNA stability by a surface-mediated T cell activation pathway (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-04-21
    Description: Quiescent T cells can be induced to express many genes by mitogen or antigen stimulation. The messenger RNAs of some of these genes undergo relatively rapid degradation compared to messenger RNAs from constitutively expressed genes. A T cell activation pathway that specifically regulates the stability of messenger RNAs for the lymphokines interleukin-2, interferon-gamma, tumor necrosis factor-alpha, and granulocyte-macrophage colony-stimulating factor is induced by stimulation of the CD28 surface molecule. This pathway does not directly affect the steady-state messenger RNA level, transcription, or messenger RNA half-life of other T cell activation genes, including c-myc, c-fos, IL-2 receptor, and the 4F2HC surface antigen. These data show that stimuli received at the cell surface can alter gene expression by inducing specific changes in messenger RNA degradation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lindstein, T -- June, C H -- Ledbetter, J A -- Stella, G -- Thompson, C B -- New York, N.Y. -- Science. 1989 Apr 21;244(4902):339-43.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of Michigan, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2540528" target="_blank"〉PubMed〈/a〉

    Inhibition of T cell receptor expression and function in immature CD4+CD8+ cells by CD4 (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-09-28
    Description: Most immature CD4+CD8+ thymocytes express only a small number of T cell receptor (TCR) molecules on their surface, and the TCR molecules they do express are only marginally capable of transducing intracellular signals. TCR expression and function was not intrinsically low in immature CD4+CD8+ thymocytes, but was found to be actively inhibited by CD4-mediated signals. Indeed, release of CD4+CD8+ thymocytes from CD4-mediated signals resulted in significant increases in both TCR expression and signaling function. These results suggest that, in CD4+CD8+ cells developing in the thymus, increased TCR expression and function requires release from CD4-mediated inhibition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakayama, T -- June, C H -- Munitz, T I -- Sheard, M -- McCarthy, S A -- Sharrow, S O -- Samelson, L E -- Singer, A -- New York, N.Y. -- Science. 1990 Sep 28;249(4976):1558-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Experimental Immunology Branch, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2120773" target="_blank"〉PubMed〈/a〉

    Differential regulation of HIV-1 fusion cofactor expression by CD28 costimulation of CD4+ T cells (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-04-11
    Description: Activation of CD4(+) T lymphocytes from human immunodeficiency virus-type 1 (HIV-1)-infected donors with immobilized antibodies to CD3 and CD28 induces a virus-resistant state. This effect is specific for macrophage-tropic HIV-1. Transcripts encoding CXCR4/Fusin, the fusion cofactor used by T cell line-tropic isolates, were abundant in CD3/CD28-stimulated cells, but transcripts encoding CCR5, the fusion cofactor used by macrophage-tropic viruses, were not detectable. Thus, CD3/CD28 costimulation induces an HIV-1-resistant phenotype similar to that seen in some highly exposed and HIV-uninfected individuals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carroll, R G -- Riley, J L -- Levine, B L -- Feng, Y -- Kaushal, S -- Ritchey, D W -- Bernstein, W -- Weislow, O S -- Brown, C R -- Berger, E A -- June, C H -- St Louis, D C -- New York, N.Y. -- Science. 1997 Apr 11;276(5310):273-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Henry M.

    Antiviral effect and ex vivo CD4+ T cell proliferation in HIV-positive patients as a result of CD28 costimulation (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-06-28
    Description: Because stimulation of CD4+ lymphocytes leads to activation of human immunodeficiency virus-type 1 (HIV-1) replication, viral spread, and cell death, adoptive CD4+ T cell therapy has not been possible. When antigen and CD28 receptors on cultured T cells were stimulated by monoclonal antibodies (mAbs) to CD3 and CD28 that had been immobilized, there was an increase in the number of polyclonal CD4+ T cells from HIV-infected donors. Activated cells predominantly secreted cytokines associated with T helper cell type 1 function. The HIV-1 viral load declined in the absence of antiretroviral agents. Moreover, CD28 stimulation of CD4+ T cells from uninfected donors rendered these cells highly resistant to HIV-1 infection. Immobilization of CD28 mAb was crucial to the development of HIV resistance, as cells stimulated with soluble CD28 mAb were highly susceptible to HIV infection. The CD28-mediated antiviral effect occurred early in the viral life cycle, before HIV-1 DNA integration. These data may facilitate immune reconstitution and gene therapy approaches in persons with HIV infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levine, B L -- Mosca, J D -- Riley, J L -- Carroll, R G -- Vahey, M T -- Jagodzinski, L L -- Wagner, K F -- Mayers, D L -- Burke, D S -- Weislow, O S -- St Louis, D C -- June, C H -- AI29331/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1996 Jun 28;272(5270):1939-43.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Naval Medical Research Institute, Bethesda, Maryland 20889, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8658167" target="_blank"〉PubMed〈/a〉

    Regulation of TCR signaling by CD45 lacking transmembrane and extracellular domains (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-23
    Description: The CD45 protein is a transmembrane tyrosine phosphatase that is required for normal T cell receptor (TCR)-mediated signaling. A chimeric complementary DNA encoding the intracellular enzymatically active portion of murine CD45 preceded by a short amino-terminal sequence from p60c-src was transfected into CD45- T cells. Expression of this chimeric protein corrected most of the TCR signaling abnormalities observed in the absence of CD45, including TCR-mediated enhancement of tyrosine kinase activity and Ca2+ flux. Thus, the enzymatically active intracellular portion of CD45 is sufficient to allow TCR transmembrane signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Volarevic, S -- Niklinska, B B -- Burns, C M -- June, C H -- Weissman, A M -- Ashwell, J D -- New York, N.Y. -- Science. 1993 Apr 23;260(5107):541-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immune Cell Biology, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8475386" target="_blank"〉PubMed〈/a〉

    In vivo calcium elevations in thymocytes with T cell receptors that are specific for self ligands (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-07-03
    Description: Selection of the T cell receptor (TCR) repertoire in the thymus probably involves TCR-mediated signals transduced in developing thymocytes after interaction with thymic stromal cells bearing self ligands. TCR-transduced signals should have identifiable consequences that would distinguish thymocytes whose TCRs have been engaged by self ligands from those whose TCRs have not. Among thymocytes expressing a transgenic TCR of defined specificity, a large number had elevated intracellular calcium concentrations but only when resident in a negatively selecting thymus in which their self ligand was expressed. Thus, developing thymocytes are stimulated by endogenous ligands in vivo to mobilize intracellular calcium, and increased intracellular calcium concentrations may reflect the consequences of intrathymic signaling associated with thymic negative selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakayama, T -- Ueda, Y -- Yamada, H -- Shores, E W -- Singer, A -- June, C H -- New York, N.Y. -- Science. 1992 Jul 3;257(5066):96-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Experimental Immunology Branch, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1621102" target="_blank"〉PubMed〈/a〉

    HIV-1-infected T cells show a selective signaling defect after perturbation of CD3/antigen receptor (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-07-29
    Description: The binding of antigen or monoclonal antibody to the T cell receptor for antigen or the closely associated CD3 complex causes increases in the concentration of intracellular ionized calcium and subsequent cell proliferation. By measuring second messenger production in primary cultures of human immunodeficiency virus (HIV-1)--infected T cells stimulated with monoclonal antibodies specific for either CD3 or CD2, a specific impairment of membrane signaling was revealed. The HIV-1--infected T cells were unable to mobilize Ca2+ after stimulation with anti-CD3, whereas CD2-induced calcium mobilization remained intact. Furthermore, the HIV-1--infected cells proliferated poorly after CD3 stimulation, although the cells retained normal DNA synthesis in response to interleukin-2 stimulation. These results show that the signals initiated by CD2 and CD3 can be regulated independently within the same T cell; uncoupling of signal transduction after antigen-specific stimulation provides a biochemical mechanism to explain, in part, the profound immunodeficiency of patients with HIV-1 infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Linette, G P -- Hartzman, R J -- Ledbetter, J A -- June, C H -- New York, N.Y. -- Science. 1988 Jul 29;241(4865):573-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Georgetown University School of Medicine, Washington, DC 20007.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2899908" target="_blank"〉PubMed〈/a〉
