冠状病毒免疫逃逸机制研究进展

Progress of research on immune escape mechanism of coronavirus

  • 摘要: 冠状病毒是人和动物的重要致病原,其中新型冠状病毒肺炎(coronavirus disease 2019,COVID-19)给人类健康带来了致命威胁。宿主固有免疫反应是宿主抵抗病原体入侵的第一道防线,但过激的免疫应答也会加重病毒感染和病理损伤。病毒免疫逃逸是冠状病毒的重要致病机制。本文主要从宿主免疫传感器、干扰素、细胞因子和冠状病毒免疫逃逸方面重点阐述了冠状病毒的致病机制,以期为抗冠状病毒药物的研发提供理论参考。

     

    Abstract: Coronavirus is an important pathogen of humans and animals. Among them, the novel coronavirus disease (COVID-19) breaking out in 2019 has brought a fatal threat to human health. The host"s innate immune response is the host"s first line of defense against pathogen invasion, but an excessive immune response can also aggravate viral infection and pathological damage. The immune escape of coronavirus is a critical pathogenic mechanism causing death. This work mainly reviews the pathogenic mechanism of coronavirus immune escape from several aspects such as host immunosensor, interferon, cytokine and coronavirus antagonizing host immune response, which provide a theoretical reference for the development of anti-coronavirus drugs.
