摘要 为了探讨rhIL-18对慢性乙型肝炎(以下称乙肝)患者免疫功能的调节作用,分离55例慢性乙肝及40例正常人的外周血单个核细胞(PBMC),在HBcAg及不同浓度rhIL-18刺激下培养72h,收集其培养上清液,采用ELISA法检测其中IL-2、IL-4、γ干扰素(IFN-γ)和单核巨噬细胞集落刺激因子(GM-CSF)的含量。结果表明,PHA单独刺激下慢性乙肝组IL-2、IFN-γ和GM-CSF的含量比正常对照组显著降低,其差异具有显著性(P<0.01);HBcAg单独刺激下慢性乙肝组IL-2、IFN-γ和GM-CSF的含量升高,但仍低于正常对照组,其差异没有显著性(P>0.05);HBcAg联合不同浓度的rhIL-18刺激下,慢性乙肝组IL-2、IFN-γ和GM-CSF的含量均高于PHA组和HBcAg组,其差异具有显著性(P<0.01),但与正常对照组没有显著性(P>0.05);PBMC培养上清液中IL-2、IFN-γ和GM-CSF的水平在慢性乙肝组中随着IL-18浓度的增加呈现出增强的趋势;但各组IL-4含量变化不明显。结论:IL-18能够促进慢性乙肝患者PBMC产生大量的IL-2、IFN-γ和GM-CSF,因此在调节免疫功能和增强机体杀伤病毒感染细胞方面具有很好的应用前景。
