    A newly characterized HLA DQ beta allele associated with pemphigus vulgaris (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-02-26
    Description: The inheritance of particular alleles of major histocompatibility complex class II genes increases the risk for various human autoimmune diseases; however, only a small percentage of individuals having an allele associated with susceptibility develop disease. The identification of allelic variants more precisely correlated with disease susceptibility would greatly facilitate clinical screening and diagnosis. Oligonucleotide-primed gene amplification in vitro was used to determine the nucleotide sequence of a class II variant found almost exclusively in patients with the autoimmune skin disease pemphigus vulgaris. In addition to clinical implications, the disease-restricted distribution of this variant should provide insight into the molecular mechanisms underlying associations between diseases and HLA-class II genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sinha, A A -- Brautbar, C -- Szafer, F -- Friedmann, A -- Tzfoni, E -- Todd, J A -- Steinman, L -- McDevitt, H O -- New York, N.Y. -- Science. 1988 Feb 26;239(4843):1026-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Microbiology, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2894075" target="_blank"〉PubMed〈/a〉

    A molecular basis for MHC class II--associated autoimmunity (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-05-20
    Description: Class II major histocompatibility (MHC) molecules have an immunoregulatory role. These cell-surface glycoproteins present fragments of protein antigens (or peptides) to thymus-derived lymphocytes (T cells). Nucleotide sequence polymorphism in the genes that encode the class II MHC products determines the specificity of the immune response and is correlated with the development of autoimmune diseases. This study identifies certain class II polymorphic amino acid residues that are strongly associated with susceptibility to insulin-dependent diabetes mellitus, rheumatoid arthritis, and pemphigus vulgaris. These findings implicate particular class II MHC isotypes in susceptibility to each disease and suggest new prophylactic and therapeutic strategies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Todd, J A -- Acha-Orbea, H -- Bell, J I -- Chao, N -- Fronek, Z -- Jacob, C O -- McDermott, M -- Sinha, A A -- Timmerman, L -- Steinman, L -- New York, N.Y. -- Science. 1988 May 20;240(4855):1003-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Microbiology, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3368786" target="_blank"〉PubMed〈/a〉

    Predominant expression of T cell receptor V alpha 7 in tumor-infiltrating lymphocytes of uveal melanoma (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-08-10
    Description: Expression of T cell receptor (TCR) V alpha genes in tumor-infiltrating lymphocytes (TILs) within intraocular melanoma was studied. Primers for 18 different human TCR V alpha families were used to analyze TCR V alpha-C alpha gene rearrangements in TIL in these melanomas obtained at surgery. A limited number of TCR V alpha genes were expressed and rearranged in these tumors, and TILs expressing V alpha 7 were found in seven of eight of these uveal melanomas. TCR gene usage is also restricted in experimental autoimmune disease, in T cells within organs like skin and other epithelial tissues, and in the brain of patients with multiple sclerosis (MS). The restricted usage of TCR genes in TIL may indicate that a specific antigen in these melanomas is targeted.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nitta, T -- Oksenberg, J R -- Rao, N A -- Steinman, L -- New York, N.Y. -- Science. 1990 Aug 10;249(4969):672-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Stanford University Medical Center, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2382141" target="_blank"〉PubMed〈/a〉
