T细胞的识别具有抗原特异性,并为一种称之为T细胞抗原受体的复合体所介导。此受体是蛋白质异二聚体,存在于T细胞表面,由二硫键连接α和β链组成。多年来企图从分子结构上去研究T细胞识别抗原的应答作用,但都没有成功。直到这几年我们和其他的实验室才分离出T细胞抗原受体的α和β T cell recognition is antigen-specific and is mediated by a complex called the T cell antigen receptor. This receptor is a protein heterodimer that is present on the surface of T cells and consists of disulfide-linked α and β chains. Over the years attempts to study the molecular structure of T-cell antigen recognition response, but none have been successful. It was not until a few years ago that we isolated the alpha and beta T-cell antigen receptors from other labs
