    Description: Multiple sclerosis (MS) may be an autoimmune disease mediated by T cells specific for a myelin protein. Investigations have demonstrated myelin basic protein (MBP)-reactive T cells that were activated in vivo in MS patients, suggesting that MBP may be a target antigen in MS. The variable (V) region of the T cell receptor (TCR) beta chain was examined among 83 T cell lines from both MS patients and healthy subjects that were reactive with the immunodominant region of human MBP (residues 84 to 102) or with a second immunodominant region of MBP (143 to 168). V beta 17 and to a lesser extent V beta 12 were frequently used in recognition of MBP(84-102) among different individuals. In contrast, V beta 17 was very infrequent among lines reactive with MBP (143-168). These data demonstrate shared TCR V beta gene usage for the recognition of immunodominant regions of the human autoantigen MBP. Such TCR structures may be used as targets for specific immunotherapy in MS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wucherpfennig, K W -- Ota, K -- Endo, N -- Seidman, J G -- Rosenzweig, A -- Weiner, H L -- Hafler, D A -- 1 K11 HL 02228-01/HL/NHLBI NIH HHS/ -- NS 00981/NS/NINDS NIH HHS/ -- R01 NS 24247/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1990 May 25;248(4958):1016-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1693015" target="_blank"〉PubMed〈/a〉

    Description: Experimental autoimmune encephalomyelitis (EAE) is a cell-mediated autoimmune disease that serves as an animal model for multiple sclerosis. Oral administration of myelin basic protein (MBP) suppresses EAE by inducing peripheral tolerance. T cell clones were isolated from the mesenteric lymph nodes of SJL mice that had been orally tolerized to MBP. These clones were CD4+ and were structurally identical to T helper cell type 1 (TH1) encephalitogenic CD4+ clones in T cell receptor usage, major histocompatibility complex restriction, and epitope recognition. However, they produced transforming growth factor-beta with various amounts of interleukin-4 and interleukin-10 and suppressed EAE induced with either MBP or proteolipid protein. Thus, mucosally derived TH2-like clones induced by oral antigen can actively regulate immune responses in vivo and may represent a different subset of T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Y -- Kuchroo, V K -- Inobe, J -- Hafler, D A -- Weiner, H L -- AR/A143220/AR/NIAMS NIH HHS/ -- NS29352/NS/NINDS NIH HHS/ -- NS30843/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 26;265(5176):1237-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7520605" target="_blank"〉PubMed〈/a〉

    Description: Rheumatoid arthritis is an inflammatory synovial disease thought to involve T cells reacting to an antigen within the joint. Type II collagen is the major protein in articular cartilage and is a potential autoantigen in this disease. Oral tolerization to autoantigens suppresses animal models of T cell-mediated autoimmune disease, including two models of rheumatoid arthritis. In this randomized, double-blind trial involving 60 patients with severe, active rheumatoid arthritis, a decrease in the number of swollen joints and tender joints occurred in subjects fed chicken type II collagen for 3 months but not in those that received a placebo. Four patients in the collagen group had complete remission of the disease. No side effects were evident. These data demonstrate clinical efficacy of an oral tolerization approach for rheumatoid arthritis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trentham, D E -- Dynesius-Trentham, R A -- Orav, E J -- Combitchi, D -- Lorenzo, C -- Sewell, K L -- Hafler, D A -- Weiner, H L -- AG00294/AG/NIA NIH HHS/ -- MO1 RR01032/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1993 Sep 24;261(5129):1727-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Beth Israel Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8378772" target="_blank"〉PubMed〈/a〉
