摘要
Abstract
In this study, we choose the asian H5N1 subtype avian influenza virus, use software to analyze the gene sequences of the HA1 (Hemagglutnin, HA, hemagglutinin) and NP (Nucleocapsid protein, capsid protein), and optimize major T cell epitopes and B cell epitopes of the HA1 protein and the major CTL (Cytotoxicity T lymphocyte cytotoxic T lymphocyte) epitope of the NP protein. According to these preferred epitopes, we designed the avian influenza virus subtype H5N1 recombinant vaccine. Genetically engineered vaccine expression vector pRSET-AIV was constructed, exogenous gene can be well expressed in E, coli system. Mice immunized with expression products, serum IgA and IgG antibody levels were significantly increased, IL-2, IL-4 and IFN-y cytokines were tested in vitro spleen cells. The antigen of genetic engineering was verified. It's confirmed that the vaccine stimulates the cellulat's immunity while it activates the humoral immunity.关键词
