| 摘 要： | 目的通过观察哮喘小鼠骨髓树突细胞的表达,以及Toll样受体(TLR2和TLR4)在骨髓树突细胞中的表达,探讨温阳补肾方对TLR信号介导的骨髓树突细胞在哮喘发病机制中的作用。方法 50只BALB/c小鼠随机分为正常对照组、模型组、中药组、西药组、中西医结合组,每组10只。各组进行相应干预。小鼠肺组织切片进行苏木素-伊红(HE)染色,观察形态结构及炎症浸润情况;采用酶联免疫吸附法(ELISA)检测肺泡灌洗液中的IL-4、IL-5、IFN-γ的含量;分离培养各组小鼠的骨髓树突细胞,在倒置相差显微镜和扫描电镜下观察树突细胞的形态变化;RT-PCR检测骨髓树突细胞中TLR2和TLR4 mRNA的表达。结果肺组织病理可见模型组小鼠气道黏膜层增厚,周围有明显的炎症细胞浸润,各治疗组炎症均有不同程度的减轻。与正常对照组比较,模型组小鼠肺泡灌洗液中IL-4表达水平上调,INF-γ水平下调,差异有统计学意义(P0.05)。与模型组比较,中药组、西药组、中西医结合组IL-4表达均下调,差异有统计学意义(P0.05)。与模型组比较,中药组和中西医结合组均可上调INF-γ水平,差异有统计学意义(P0.05)。模型组骨髓树突细胞中TLR2、TLR4 mRNA的表达明显高于正常对照组(P0.05),各治疗组均可下调骨髓树突细胞中TLR2、TLR4mRNA的表达,与模型组比较,差异有统计学意义(P0.05)。结论温阳补肾方可以降低哮喘小鼠的气道阻力和减轻气道炎性反应,这可能是温肾方通过介导BMDC-TLR2/TLR4通路的信号转导,从而显著上调Th1型细胞因子分泌,下调Th2型细胞因子表达,进而调节Th1/Th2的免疫平衡。
