摘要 为探讨白细胞介素18(IL-18)在乙型肝炎病毒(HBV)感染中的作用,从68例HBV感染者(无症状携带者15例,慢性肝炎35例,重型肝炎18例)和24例健康献血员血液中分离出外周血单个核细胞(PBMC)及血清,应用RT-PCR及ELISA分别对IL-18基因的转录和血清中IL-18的含量进行检测。结果表明,重型肝炎组IL-18基因转录水平高于正常对照组(P<0.01),无症状携带者组低于正常对照组(P<0.05,P<0.01),慢性肝炎组与正常对照组差异无显著意义(P>0.05)。随着病情加重,IL-18水平上升。肝组织炎症活动度不同的慢性肝炎病人之间IL-18基因转录水平及其血清中的含量的差异均有显著意义(P<0.05),肝组织炎症程度越重,IL-18含量越高。结论:IL-18可能参与了宿主对HBV的免疫应答,与肝脏炎症程度相关。
