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〉
