摘要:

刚地弓形虫(简称弓形虫)呈世界性分布,是重要的专性细胞内致病原虫,可引起人兽共患的弓形虫病,给人群健康和畜牧业生产造成严重的危害。研究发现,Ⅰ型弓形虫株能够逃避宿主细胞自噬的杀伤作用,其机制可能是通过改变宿主自噬相关蛋白的表达水平;而Ⅱ型和Ⅲ型弓形虫株均能被宿主细胞的自噬系统有效地清除或抑制。本文综述了弓形虫感染与宿主细胞自噬相互作用的研究进展及其相关分子机制。

Abstract:

Toxoplasma gondii is an important obligate intracellular pathogenic protozoan with worldwide distribution that may cause zoonotic toxoplasmosis, severely impacting the human health and the economy of animal husbandry. Studies have shown that the type I strain of T. gondii can escape from the killing effect of autophagy in host cells by changing the expression of autophagy-related proteins in the host, while the type Ⅱ and Ⅲ strains of T. gondii can be effectively cleared up or suppressed by the autophagy system of host cells. This review provides an update on the interplay between T. gondii infection and host cell autophagy system and the related molecular mechanisms.

Key words: Toxoplasma gondii, Infection, Host cell, Autophagy, Interplay
