摘要: 牛冠状病毒(bovine coronavirus,BCoV)是一种能感染牛肠道、呼吸道引起新生犊牛腹泻、成年牛冬季痢疾和各年龄段的牛呼吸道疾病的重要病原体,严重危害着养牛业的发展。刺突(spike,S)蛋白是该病毒主要的结构蛋白和免疫原性蛋白,在病毒初始感染和诱导保护性免疫中发挥重要作用。本文就该病毒刺突蛋白的结构特征、生物学功能及应用研究、免疫原性、变异原因和潜在双受体系统的最新研究进展做一阐述,期望为新型疫苗研制和靶点治疗药物开发提供科学依据,以便制定快速有效的安全防治对策应对预出现的新毒株。

Abstract: Bovine coronavirus is an important pathogen that can infect bovine intestinal tract, respiratory tract and cause calf diarrhea, adult winter dysentery and bovine respiratory diseases of all ages, which seriously endangers the development of cattle industry. The spike protein is the main structural protein and immunogenic protein of the virus, which plays an important role in the initial infection of the virus and the induction of protective immunity. This paper describes the structural features, biological functions and application studies of the virulence of the spike protein, as well as its immunogenicity, causes of mutation and the latest research progress of the potential dual-receptor system, with the hope of providing a scientific basis for the development of a new type of vaccine and target therapeutic drugs, so as to formulate a rapid and effective safe prevention and control countermeasures to deal with the emergence of new strains of the disease.

Key words: bovine coronavirus, spike protein, biological function, protein variation
