When Shigella infect the intestinal epithelium, they deliver several effectors through the type III secretion system (T3SS) into the surrounding space and directly into the host-cell cytoplasm, where they can mimic and usurp host cellular functions or subvert host-cell signalling pathways and the immune response. Although bacterial strategies and mechanisms of infection vary greatly, recent studies of Shigella effectors have revealed that Shigella possess a highly evolved strategy for infection.
当志贺氏菌感染肠道上皮细胞时，它们通过III型分泌系统（T3SS）将多种效应蛋白释放到周围空间并直接释放到宿主细胞的细胞质中，在那里它们可以模拟并篡夺宿主细胞功能，或破坏宿主细胞的信号通路和免疫反应。尽管细菌的感染策略和机制差异很大，但最近对志贺氏菌效应蛋白的研究表明，志贺氏菌拥有一种高度进化的感染策略。
