多发性硬化(MS)可能是一种由髓磷脂蛋白特异性T细胞介导的自身免疫性疾病。调查展示了髓磷脂碱性蛋白(MBP)反应性T细胞激活体内的MS患者,建议MBP可能是女士变量(V)地区的目标抗原T细胞受体(TCR)β链的检查在83 T细胞系来自MS患者和健康受试者反应immunodominant地区人类MBP(残留84年至102年)或第二immunodominant地区MBP(143年至168年)。Vβ17和较少程度的Vβ12在不同个体中被频繁地用于识别MBP(84-102)。相比之下,Vβ17在与MBP反应的细胞系中非常少见(143-168)。这些数据表明共享的TCR v β基因用于识别人类自身抗原MBP的免疫优势区域。这种TCR结构可以作为MS特异性免疫治疗的靶点。
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) β 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). Vβ17 and to a lesser extent Vβ12 were frequently used in recognition of MBP(84-102) among different individuals. In contrast, Vβ17 was very infrequent among lines reactive with MBP (143-168). These data demonstrate shared TCR Vβgene 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.
