摘要
Ⅲ型分泌系统是目前细菌中已知的最为复杂的分泌系统,也是致病性耶尔森菌包括鼠疫耶尔森菌、小肠结肠炎耶尔森菌和假结核耶尔森菌所共有的重要致病策略之一。简要综述了耶尔森菌Ⅲ型分泌系统的遗传构成、分泌装置的结构和组成、效应蛋白分泌及调控、效应蛋白的功能等方面的主要研究成果和研究进展。
Type Ⅲ secretion system(T3SS) is one of the most complicated secretion system in bacteria hitherto. Yersinia T3SS is a common pathogenesis mechanism shared by three human pathogenic Yersinia species, Y.pestis, Y. pseudotuberculosis and Y.enterocolitica. This review focused on the aspects of genetic elements composition of T3SS, structure and the assembly of the injectisome, secretion of effeetors and its tight regulations and the molecular functions of effeetors to present the current understanding of Yersinia T3SS.
