摘要: 刚地弓形虫(Toxoplasma gondii)是一种重要的人兽共患寄生原虫,具有中间宿主广泛、生活史复杂、传播方式多样、呈全球性分布等特点,可感染几乎所有的恒温动物,导致人兽共患的弓形虫病。弓形虫慢性感染约1/3的世界人口,对免疫缺陷患者、孕妇、孕畜的健康更是造成严重威胁。致密颗粒蛋白是由致密颗粒(弓形虫的一种亚细胞分泌器官)分泌的蛋白质,它们可通过操控宿主(细胞)基因表达、信号通路进而调控宿主细胞的免疫反应和细胞周期,并在蛋白质的转运和定位、营养物质的摄取、纳米管网络(IVN)的形成与稳定性的维持、逸出、慢性感染等生理过程中发挥重要作用。本文综述弓形虫致密颗粒蛋白基本生物学功能的最新研究进展,旨在为深入研究弓形虫的致病机制、鉴定新的抗弓形虫潜在药物靶点和疫苗候选分子提供借鉴。

Abstract: Toxoplasma gondii is an important zoonotic parasite with a wide range of intermediate hosts, complex life history, diverse modes of transmission and global distribution, which can infect almost all warm-blood animals, including humans, causing zoonotic toxoplasmosis. About one third of the world human population are chronically infected with T. gondii, which poses a serious health threat to immune deficiency patients, pregnant women and pregnant animals. Therefore, T. gondii is an important zoonotic parasite. Dense granule protein family secreted by the dense granules, one of the important subcellular secretory organelles of T. gondii, plays important roles in many biological processes, such as regulating the host cell cycle and immune response by modulating the signal pathways, gene expression, participating in the protein transport and localization, nutrient uptake, the formation and stability maintenance of intravacuolar network (IVN), as well as egress and chronic infection of T. gondii. In this review, the basic biological functions of the dense granule proteins are summarized in order to provide new research ideas for the pathogenesis of T. gondii, the discovery of potential drug targets against T. gondii and the development of anti-T. gondii vaccines.

Key words: Toxoplasma gondii, toxoplasmosis, dense granule proteins, biological function
