摘要 免疫耐受包括中枢免疫耐受和外周免疫耐受。中枢免疫耐受主要通过清除胸腺中能够识别自身抗原的自身反应性T细胞;而外周免疫耐受则是通过多种途径来消除外周成熟的自身反应性T细胞。自身免疫调节因子(autoimmune regulator,Aire)在中枢与外周免疫耐受建立和维持中起着举足轻重的作用,该单基因突变可引起自身免疫性疾病综合症。大量研究资料表明Aire可能成为临床诱导移植免疫耐受、抑制移植排斥反应、根治某些自身免疫性疾病的一个新靶点。 Immune tolerance includes central immune tolerance and peripheral immune tolerance. The major mechanism of central tolerance is mainly due to clonal deletion of self-antigen-reactive T cells in the thy- mus. Peripheral tolerance mechanisms involve the deletion of peripheral mature T cells. The autoimmune regula- tor (Aire) plays an important role in the establishment and maintenance of central and peripheral immunological tolerance. Monoallelic mutations in Aire could cause autoimmune diseases. A large number of studies have shown that Aire may become a new target for the induction of tolerance in organ transplantation and the treat- ment for autoimmune diseases.
