近年来的研究表明病原体感染宿主可能是通过病毒或细菌壁上的膜糖蛋白与宿主细胞膜上的糖基专一性结合而导致的. 病毒感染宿主细胞,首先是病毒外壳的糖分子识别宿主细胞膜上的糖蛋白受体,并与之结合引起宿主细胞膜结构的改变,才能入侵到宿主细胞内. 经研究发现流感病毒外壳糖蛋白是由大小两个亚基组成,是病毒的主要抗原,由于它结构上的多变性,直接影响人群中流感流行出现 Recent studies have shown that pathogen-infected hosts may be caused by the specific binding of membrane glycoproteins on the viral or bacterial wall to glycosyl groups on the host cell membrane, which infect host cells, primarily viral molecules in the viral coat, to identify host cell membranes On the glycoprotein receptor, combined with the cause of the host cell membrane structure changes in order to invasion into the host cells.Studies have found that the influenza virus envelope glycoproteins by the size of two subunits, is the virus’s main antigen, because it Structural variability, a direct impact on the crowd in the flu epidemic
