免疫共刺激分子在T细胞活化和免疫应答的调节过程中发挥重要作用。共刺激分子CD2 8和CTLA4作为B7的受体分子 ,CD2 8在启动T细胞免疫应答中发挥重要作用 ,其中CTLA4具有更高的亲和力 ,在T细胞活化后被诱导并负调节T细胞的反应。最近发现的有一个新的诱导性免疫
Immunostimulatory molecules play an important role in the regulation of T cell activation and immune response. Costimulatory molecules CD2 8 and CTLA4, as receptor molecules of B7, play an important role in initiating T cell immune responses. CTLA4 has a higher affinity and is induced after T cell activation and negatively regulates T cell responses. Recently discovered a new induced immunity
