摘要

Myelin oligodendrocyte glycoprotein (MOG) is an important autoantigen in multiple sclerosis and in experimental autoimmune encephalomyelitis (EAE). We generated a T cell receptor (TCR) transgenic (Tg) mouse expressing a TCR derived from an encephalitogenic T cell clone specific for MOG(35-55). This mouse failed to develop EAE spontaneously and developed mild EAE at late onset when immunized with MOG(35-55). The Tg T cells produced large amounts of IL-4 when stimulated with MOG(35-55) and underwent FAS/FAS-L-mediated activation-induced cell death when stimulated with MOG(35-55) and IL-12. The unique phenotype of these autoantigen-specific T cells may represent an important mechanism of protection against autoimmune disease.
