鸡球虫诱导的宿主细胞凋亡研究进展
Research advances in Eimeria-induced host cell apoptosis in avian coccidiosis
,
本文系统综述了鸡球虫-宿主互作中凋亡调控机制的最新研究进展。研究表明:1)不同种属鸡球虫诱导宿主细胞凋亡存在差异性,柔嫩艾美耳球虫最强,巨型艾美耳球虫次之,堆型艾美耳球虫最弱,3种鸡球虫主要通过棒状体蛋白、微线蛋白和热休克蛋白等关键效应分子调控细胞凋亡;2)球虫感染过程中存在时序性凋亡调控细胞,早期通过抑制线粒体途径促进虫体定植,晚期则激活死亡受体途径以利于子代虫体释放;3)抗球虫药物中,化学类药物直接诱导虫体线粒体功能障碍,而中草药通过调节Bcl-2/Bax、caspase-3等凋亡因子发挥间接抗球虫作用。综上,这些研究发现不仅阐明了球虫致病的关键分子机制,更为基于调控的新型抗球虫药物设计和精准防控策略制定提供重要理论依据。
The latest research on the mechanism regulating apoptosis in the relationship between chicken coccidium and host are systematically reviewed in this article. Researches indicates that: 1) Different species of chicken coccidia induce host cell apoptosis differently; Eimeria tenella is the strongest, followed by Eimeria maxima and Eimeria acervulina. Each of these species primarily control cell apoptosis through important effector molecules including rhoptry proteins, microneme proteins and heat shock proteins. 2) The coccidia infection process involves a number of apoptotic regulatory cells. During the early stages, these cells inhibit the mitochondrial pathway to encourage parasite colonisation, and in the later stages, they activate the death receptor pathway to facilitate the release of progeny parasites. 3) Among the anticoccidial drugs, chemical medicines cause the parasites to directly breakdown their mitochondria, while Chinese herbal remedies work indirectly by controlling apoptotic factors such caspase-3 and Bcl-2/Bax. In summary, these studies not only shed light on the primary molecular pathways of coccidiosis pathogenesis, but also they provide a crucial theoretical foundation for the development of specifically designed prevention and control measures as well as new anti-coccidiosis medicines based on regulation.
