摘要 水泡性口炎由水泡性口炎病毒(VSV)引起。VSV基因组编码5个结构蛋白,其中基质蛋白(matrix protein,M)是其重要毒力因子,可阻遏宿主细胞mRNA由胞核向细胞质的转运,并抑制感染病毒的细胞产生I型干扰素IFNα/β,使病毒得以快速繁殖。本实验克隆了印第安那型VSV的M基因,在大肠杆菌表达系统中表达制备重组M蛋白,以M蛋白为抗原建立了检测特异M蛋白抗体的间接ELISA方法。采用建立的ELISA方法分析了VSV感染小鼠体内M蛋白抗体的变化规律。 The pathogen of VS is vesicular stomatitis virus (VSV). VSV genome consists of five structural protein genes. Matrix protein (M) is an important virulence factor for VSV,which can inhibit host mRNA transport from nucleus outside to cytoplasm in host cells. As the result, production of type I interferon by host cells can be inhibited,whereas viruses can replicate efficiently in infected cell. In our study,M gene was cloned and expressed in E. coli. Based on the recombinant M protein, indirect ELISA assay was established to detect antibody against M in VSV-inoculated SPF mice.
