动物的免疫反应是一种由细胞和可溶性因子构成的复杂的多成分系统完成的生物现象,它能迅速识别甚至杀死入侵的外来生物体。但在某些情况下,有多种寄生物能在具备完整的免疫反应的宿主体内引起长期的慢性感染,因为它们已经发展了逃避宿主免疫力的功能。近十几年来,这是国际寄生虫学界较为注目的课题之一。这里不可能广泛地讨论寄生虫的免疫逃避机理,因为那可能是一个包含了生物进化、信息遗传、抗原变异、免疫抑制等多种过程的复杂的生物医学问题;但以血吸虫感染过程中的“宿主抗原”为例就此作一述评,或有益于该类研究的开展,并供寄生虫学工作者参考。
An animal’s immune response is a biological phenomenon performed by a complex multicomponent system of cells and soluble factors that rapidly identifies and even kills invading alien organisms. However, in some cases, many parasites can cause long-term chronic infections in hosts with an intact immune response as they have evolved to evade host immunity. This past decade has been one of the more prominent topics in the international parasitology community. It is impossible to discuss the immune evasion mechanism of parasites extensively here because it may be a complex biomedical problem that involves many processes such as biological evolution, information inheritance, antigen variation, immunosuppression, etc. However, in the process of schistosomiasis infection, Host antigen "as an example to comment on this or conducive to the development of such studies, and for reference by the parasite workers.
