自从T细胞受体(TCR)基因被鉴定以来(文献[1]中的综述)已经过去了15年。与抗体的情况不同,TCR蛋白的直接结构信息在大多数时候都是可用的。然而,最近确定了分离的α和β链的晶体结构,随后不久又确定了αβ杂二聚体的结构。随后,报道了两个TCR肽-MHC(PMHC)络合物的结构。这一意外之财,以及其他更新的结构信息,阐明了TCR结合和识别pMHC的一些概括。然而,晶体结构让我们对TCR复合体的信号转导机制以及导致T细胞激活的后续事件的了解很少。最终,结晶学结果将与其他学科的实验结果相一致,以全面了解T细胞激活的分子事件
Fifteen years have passed since T-cell receptor (TCR) genes were identified (reviewed in [1]). Unlike the situation for antibodies, no direct structural information on the TCR proteins has been available for most of this time. Recently, however, the crystal structures of isolated α and β chains were determined, shortly followed by the determination of the structure of an αβ heterodimer. Subsequently, the structures of two TCR peptide—MHC (pMHC) complexes have been reported. The windfall of this, and other more recent structural information, has elucidated some generalizations for TCR binding and recognition of pMHC. The crystal structures have, however, given us very little insight into the mechanisms of signal transduction by the TCR complex and the subsequent events which lead to activation of a T cell. Ultimately, the crystallographic results will be reconciled with experiments from other disciplines for a complete understanding of the molecular events of T cell activation
