摘要 目的:构建重组表达载体P-BAP31和P-L-BAP31基因疫苗并接种小鼠,评价其诱导的体液和细胞免疫应答。方法:利用分子克隆技术,构建重组质粒P-BAP31和P-L-BAP31,同时构建P-BAP31/EGFP和P-L-BAP31/EGFP重组质粒,并将其以脂质体瞬时转染HeLa细胞,通过荧光显微镜观察目的蛋白的表达;将重组质粒P-BAP31和P-L-BAP31免疫C57BL/6小鼠,采用间接ELISA检测免疫小鼠血清中特异性抗体效价;通过酶联免疫斑点实验(ELISPOT)检测免疫脾细胞在受到BAP31抗原刺激后产生IFN-γ和IL-4细胞因子的频率;通过乳酸脱氢酶(LDH释放)试验检测小鼠特异性细胞毒性T淋巴细胞(CTL)的应答。结果:酶切及测序结果表明,成功构建了针对BAP31肿瘤抗原的P-BAP31和P-L-BAP31基因疫苗。通过荧光显微镜观察重组质粒转染的HeLa细胞,可见EGFP报告基因表达的绿色荧光。ELISA检测免疫小鼠血清中特异性抗体效价发现,带LAMP组明显高于不带LAMP组(P<0.05),且两者均高于空质粒(P-LAMP)及正常对照(N)组(P<0.01)。ELISPOT检测脾细胞分泌细胞因子IFN-γ和IL-4的频率,带LAMP组与其他组相比显著提高(P<0.01)。LDH释放试验显示,带LAMP组的特异性CTL活性高于不带LAMP组,且均高于对照组(P<0.01)。结论:构建了针对肿瘤抗原BAP31的全长基因疫苗,以其免疫C57BL/6小鼠可诱导特异性体液和细胞免疫反应,其中,P-L-BAP31基因疫苗各项免疫反应均优于P-BAP31。
