摘要 目的:探讨活化T细胞核因子cl(nuclear factor of activated T cells cl,NFATcl)与气道炎症的相关性,观察尼卡地平对哮喘小鼠气道炎症以及NFATcl蛋白表达的影响。方法:建立哮喘小鼠模型并收集支气管肺泡灌洗液(bronchoalveolar lavage fluid,BALF),ELISA法测定BALF中细胞因子IL-4、IL-5和IFN-γ的水平,免疫组化法测定气道周围淋巴细胞中NFATcl蛋白的表达。结果:IL-4、IL-5的水平与NFATcl阳性率有线性正相关(P<0.05)。哮喘小鼠IL-4、IL-5水平以及NFATcl蛋白表达较正常组升高,差异有统计学意义(P<0.05);尼卡地平干预组IL-4、IL-5水平和NFATcl表达较哮喘组降低,差异有统计学意义(P<0.05)。结论:NFATcl的激活可上调IL-4和IL-5的表达,促进哮喘的气道炎症;尼卡地平可抑制NFATcl的表达,降低细胞因子IL-4、IL-5的水平,减轻哮喘气道炎症。
