血小板膜糖蛋白Ⅵ(GPⅥ)的研究进展

血小板膜糖蛋白Ⅵ（GPⅥ）是血小板表面重要的胶原受体，能介导血小板与胶原的初期黏附，产生信号转导，提高整合蛋白受体亲合力，引起血小板聚集和血栓形成。抑制GPⅥ功能可显著抑制胶原诱导的血小板黏附、聚集和血栓形成，故GPⅥ已成为研制新型抗血小板药物的主要靶点。过去几年中，对血小板和胶原相互作用的研究取得很大进展，本文就GPⅥ的结构，GPⅥ的功能，GPⅥ功能相关因素，GPⅥ与临床等作一综述。

Advances in the Studies of platelet glycoprotein Ⅵ (GPⅥ)

Platelet glycoprotein VI (GPVI) is a major receptor for collagen on the platelet surface. It mediates the initial platelet contact with collagen, generates intracellular signals, increases the affinity of integrin receptor, and causes platelet aggregation and thrombosis. Suppression of GPVI function can significantly inhibit collagen-induced platelet adhesion, aggregation and thrombosis, so GPVI has become a novel target for antiplatelet therapy. Within the last few years, major advances have been made in understanding platelet-collagen interactions. In this paper, the advances of study on GPVI, including composition of GPVI, functions of GPVI, factors related with functions of GPVI, GPVI and clinic were summarized.
