摘要
目的 :探讨白细胞介素 10 (IL 10 )基因转染对小鼠心脏移植排斥反应中IL 12、IL 15、IL 18和IL 4表达的影响。方法 :采用小鼠颈部心脏移植模型 ,随机分为 3组 :对照组、移植组和IL 10组。于术后第 5天取移植心脏 ,用逆转录聚合酶链式反应 (RT PCR)法观察IL 12、IL 15、IL 18、IL 4及IL 10的表达情况。结果 :移植组IL 12、IL 15、IL 18表达与对照组比较明显升高 ,IL 10、IL 4表达显著降低 (均P <0 .0 1)。IL 10组IL 12、IL 15、IL 18表达与移植组比较明显降低 ,而IL 4及IL 10表达显著升高 (均P <0 .0 1)。结论 :IL 10基因转染抑制心脏移植排斥反应主要与其抑制IL 12、IL 15、IL 18等Th1型细胞因子的表达 ,促进Th2型细胞因子IL 4的表达 ,使免疫反应由Th1型向Th2型偏移有关
