摘要:

刚地弓形虫(Toxoplasma gondii)主要分3种基因型(Ⅰ型、Ⅱ型和Ⅲ型),3型虫株对宿主的毒力具有明显差异。弓形虫棒状体蛋白(rhoptry protein,ROP)中的ROP18、ROP16和ROP5在弓形虫感染过程中会被分泌到宿主细胞内,发挥调节弓形虫毒力的作用,造成不同型虫株间毒力差异,是主要的毒力调节因子。本文对国内外有关弓形虫毒力调节因子的研究进行综述。

Abstract:

Toxoplasma gondii strains are grouped into three clonal lineages(TypesⅠ,Ⅱ, and Ⅲ)with different virulence. T. gondii rhoptry proteins ROP18, ROP16, and ROP5 are the major virulence factors, which are secreted into the host cell by T. gondii during invasion and mediate the strain virulence. This paper reviews the research progress of T. gondii virulence mediating factors.
