摘要:
冠状病毒可感染哺乳动物和禽类,其高度遗传变异性显著影响其宿主范围与组织亲嗜性。近二十年来,3次由动物冠状病毒引发的人类疫情对全球公共卫生造成了严峻威胁。病毒刺突蛋白(S)是介导病毒入侵宿主细胞的关键,其S1亚基通过识别并结合细胞表面受体,直接决定了病毒的宿主适应性与组织趋向性。近年来,随着冷冻电镜技术的发展,多种冠状病毒S蛋白的高分辨率三维结构得以解析。本综述基于冷冻电镜解析的冠状病毒S蛋白的高分辨率三维结构系统总结了不同动物与人类冠状病毒S1亚基的结构特征及其与多种细胞受体的互作机制,以期在为阐明冠状病毒跨种传播规律、预警潜在流行风险及开发广谱抗病毒药物提供依据。
Abstract:
Coronaviruses can infect mammals and birds, and their high genetic variability significantly affects their host range and tissue tropism. Over the past two decades, three human epidemics caused by animal coronaviruses have posed a severe threat to global public health. The viral spike protein (S) is crucial for mediating viral entry into host cells, and its S1 subunit directly determines viral host adaptability and tissue tropism by recognizing and binding to cell surface receptors. In recent years, with the development of cryo-electron microscopy technology, the high-resolution three-dimensional structures of spike proteins from various coronaviruses have been resolved. Based on these high-resolution three-dimensional structures of coronavirus spike proteins determined by cryo-electron microscopy, this review systematically summarizes the structural characteristics of the S1 subunit from different animal and human coronaviruses, as well as the interaction mechanisms between the S1 subunit and various cellular receptors. It is expected to provide a foundation for elucidating the rules of coronavirus cross-species transmission, early warning of potential epidemic risks, and developing broad-spectrum antiviral drugs.
