摘要:
探讨携带SIRPαFc(SF)融合基因蛋白基因的重组腺病毒Ad35SF感染T细胞后对T细胞功能的影响。腺病毒Ad35SF感染Jurkat T细胞后,通过Western blotting及ELISA方法检测细胞上清中SF融合蛋白的大小与表达量;通过流式分析技术检测细胞表面CD47的封闭情况;通过CCK8方法检测细胞的增殖与对肿瘤细胞的杀伤作用。结果表明,Ad35SF构建成功,其感染Jurkat T细胞后,能在其内表达并分泌产生大小约为48 kD的SF蛋白,细胞上清中SF的表达量可到达19.1 μg/mL。Ad35SF(MOI=1)感染Jurkat细胞18 h后,细胞CD47阳性比例从97.06％下降到15.32％;当Ad35 SF感染复数增加至5,10时,CD47阳性比率进一步降低至2.94%和173%。相对于空病毒对照组,Ad35SF感染Jurkat细胞48 h后其增殖效果提高了29％,对肝癌细胞株Hep 3B的杀伤作用提升25.6％( p <0.01)。结果表明构建的重组腺病毒Ad35 SF能有效感染Jurkat细胞并在其内表达分泌SF蛋白,封闭细胞表面的CD47,同时显著提高Jurkat细胞的增殖能力和对肝癌细胞的杀伤作用。
