顶复门寄生虫负责许多重要的人类病理学。显然,作为真核生物,它们与各自的宿主细胞共享许多细胞特征和途径。其中之一是自噬,这是一个涉及细胞自身成分降解的过程。尽管如此,这些细胞内的寄生虫似乎呈现出许多原始特征,与它们在进化上非常遥远的宿主细胞相比。在哺乳动物和其他后生动物中,自噬已被确定为防御微生物病原体的重要贡献者。因此,宿主自噬也可能在顶复门寄生虫的控制中发挥关键作用,尽管其潜在的操纵和细胞内寄生虫的颠覆在宿主和寄生虫自噬的调节中产生了复杂的相互作用。在这篇简短的综述中,我们总结了寄生虫及其宿主细胞中自噬的现有知识,在感染三种顶复虫的背景下:疟原虫,弓形虫和泰勒虫。
Apicomplexan parasites are responsible for a number of important human pathologies. Obviously, as Eukaryotes they share a number of cellular features and pathways with their respective host cells. One of them is autophagy, a process involved in the degradation of the cell's own components. These intracellular parasites nonetheless seem to present a number of original features compared to their very evolutionarily distant host cells. In mammals and other metazoans, autophagy has been identified as an important contributor to the defence against microbial pathogens. Thus, host autophagy also likely plays a key role in the control of apicomplexan parasites, although its potential manipulation and subversion by intracellular parasites creates a complex interplay in the regulation of host and parasite autophagy. In this mini-review, we summarise current knowledge on autophagy in both parasites and their host cells, in the context of infection by three Apicomplexa: Plasmodium, Toxoplasma, and Theileria.
