弓形虫几乎可入侵一切温血脊椎动物的有核细胞,造成较为严重的人兽共患弓形虫病,威胁人类和动物的健康.与其他病原菌入侵宿主的方式有所不同,弓形虫以一种独特的运动方式入侵宿主细胞,其中滑行运动是弓形虫成功入侵宿主细胞的关键环节.弓形虫入侵宿主是一个连续且复杂的过程,在入侵的过程中,虫体可分泌一系列蛋白质分子,以介导虫体在宿主细胞中滑行、黏附与入侵等重要功能.研究弓形虫入侵宿主细胞的详细过程,可进一步揭示介导或参与虫体入侵宿主细胞的重要蛋白质分子的作用及其机制,为弓形虫疾病的预防与治疗药物的研发提供参考.

Cystic echinoccosis is an important zoonotic parasitic disease of humans and animals caused by Echinococcus granulosus. At present, there is no effective method for the disease, so effective diagnostic methods are particularly important for the prevention and control of cystic echinococcosis. According to the growth stage of Echinococcus granulosus in the intermediate host, the diagnostic antigens can be divided into: oncosphere stage antigen, protoscoleces stage antigen and cystic fluid stage antigen. This article introduces the latest advances in diagnostic antigens to provide a reference for the study of antigens used in immunodiagnosis of cystic echinococcosis.
