牛传染性鼻气管炎病毒糖蛋白gB和gD的研究进展

Research Progress on Glycoprotein gB and gD of Infectious Bovine Rhinotracheitis Virus

  • 摘要: 牛传染性鼻气管炎(Infectious bovine rhinotracheitis,IBR)是牛的重要传染病,临床以呼吸道症状为主,伴有结膜炎、乳腺炎、流产等症状。其病原是牛传染性鼻气管炎病毒(Infectious bovine rhinotracheitis virus,IBRV),又称牛疱疹病毒1型(Bovine herpesvirus 1,BHV-1),共编码30~40种结构蛋白,其中11种为囊膜糖蛋白。糖蛋白在病毒吸附、侵入宿主细胞的过程中发挥重要作用。糖蛋白gB对病毒侵入宿主细胞、在细胞间扩散及复制至关重要;糖蛋白gD在病毒复制、传播和感染机制方面作用重大,具有良好的免疫原性,是诱导产生中和抗体的主要糖蛋白。对gB、gD的研究不仅可从蛋白层面解析病毒侵染机制,还能够为牛传染性鼻气管炎的临床诊断和预防提供理论依据。本文针对牛传染性鼻气管炎病毒的主要糖蛋白gB、gD的研究结果进行综述,分析其生物学功能以及在疫苗和诊断方面的应用,以期为牛传染性鼻气管炎侵染机制和防控提供参考。

     

    Abstract: Infectious bovine rhinotracheitis is an important infectious disease of cattle. The clinical symptoms of the disease were principally respiratory ones that may be accompanied by conjunctivitis, mastitis, abortion, etc. The pathogenic virus is also known as bovine herpesvirus type 1. It encodes 30 to 40 structural proteins with 11 envelope glycoproteins, which play an important role in the process of virus adsorption and host cell invasion. Glycoprotein gB is essential for the virus to invade, spread, and replicate on host cells. Glycoprotein gD is critical in viral replication, transmission, and infection with strong immunogenicity that induces neutralizing antibodies. Studying gB and gD not only helps decipher the infection mechanism at the molecular level but also leads to new clinical diagnosis and prevention method developments on rhinotracheitis. This article summarizes recent research results on glycoprotein gB and gD concerning the biological functions and applications of these proteins in producing vaccines and generating advanced diagnosis methodologies for the infectious disease in cattle.
