摘  要:
为评价牛病毒性腹泻-黏膜病病毒(BVDV)E2截短基因重组卡介苗对小鼠的免疫效果,用BVDV-E2截短基因重组卡介苗pMV361-E11、pMV361-E12、pMV361-E13、pMV361-E21、pMV361-E22、pMV361-E23及卡介苗、BVDV灭活苗和生理盐水对试验小鼠进行腹腔免疫,在三免后14d取其脾脏对T、B淋巴细胞、树突状细胞及Th1细胞等细胞因子进行流式细胞术检测,评价各重组卡介苗的免疫效果。结果显示,pMV361-E23重组卡介苗组中各细胞因子的表达量尽管有个别因子在同组中不是最高,但均高于同组生理盐水的表达量(除INF-γ检测中略低外);pMV361-E12组中IL-12的含量高达9.7。表明pMV361-E23和pMV361-E122组截短重组卡介苗免疫效果较好,为预防牛病毒性腹泻病以及新型疫苗的研制奠定基础。

摘  要:
To evaluate immune efficacy of recombinant BCG(rBCG),which encodes bovine viral diarrhea-mucosal disease virus(BVDV)E2truncated protein,specific pathogen free(SPF)mice were intraperitoneally injected with the recombinant pMV361-E11,pMV361-E12,pMV361-E13,pMV361-E21,pMV361-E22,pMV361-E23,and BCG,inactivated BVDV vaccine and sterile saline were set as the control groups.The level of T-lymphocyte,B-lymphocyte,dendritic cell and Th1cell were detected by flow cytometry.Results showed that immune effect of the pMV361-E23-rBCG is better than other groups.IL-12percentage numbers from spleen in pMV361-E12-rBCG was the highest,achieving 9.7.In conclusion,pMV361-E23-rBCG and pMV361-E12-rBCG have better immune efficacy.This study laid foundation for research on newtype gene engineering vaccine against BVDV.
