T细胞活化需要T细胞抗原受体与主要组织相容性复合体(抗原)的蛋白质相互作用。这种相互作用发生在一个专门的细胞-细胞连接,称为免疫突触。免疫突触包含至少两个功能域:一个中心的抗原受体簇和周围的粘附分子环。T细胞抗原受体(TCR)和粘附分子的分离基于大小,其中TCR相互作用跨越15 nm,并且淋巴细胞功能相关抗原-1(LFA-1)相互作用跨越30-40 nm。因此,突触不是一个空的间隙,而是一个由粘附分子和信号分子填充的空间。本章考虑免疫突触的四个方面:迁移和停止信号的作用,细胞骨架的作用,自身抗原复合物的作用,以及第二信号的作用。
T-cell activation requires interaction of T-cell antigen receptors with proteins of the major histocompatibility complex (antigen). This interaction takes place in a specialized cell–cell junction referred to as an immunological synapse. The immunological synapse contains at least two functional domains: a central cluster of engaged antigen receptors and a surrounding ring of adhesion molecules. The segregation of the T-cell antigen receptor (TCR) and adhesion molecules is based on size, with the TCR interaction spanning 15 nm and the lymphocyte-function-associated antigen-1 (LFA-1) interaction spanning 30–40 nm between the two cells. Therefore, the synapse is not an empty gap, but a space populated by both adhesion and signaling molecules. This chapter considers four aspects of the immunological synapse: the role of migration and stop signals, the role of the cytoskeleton, the role of self-antigenic complexes, and the role of second signals.
