摘要 研究淫羊藿苷(ICA)对小鼠髓源树突状细胞(DC)分化及成熟的影响。小鼠骨髓细胞用GM-NSF和IL-4培养5 d,然后用免疫磁珠法纯化DC细胞,试验组分别加入淫羊藿苷2、5、10和20 mg/m L,空白对照组加等量RPMI-1640,阳性对照组加脂多糖(LPS),6组分别同时作用48 h。流式细胞仪检测CDllc、主要组织相容性复合物(MHC)-Ⅱ类分子及协同刺激分子CD80、CD86表达水平和细胞摄取抗原的能力,ELISA检测产生的细胞因子(IL-2、IL-10、IL-12),混合淋巴细胞反应检测细胞提呈抗原的能力。结果表明:4个添加淫羊藿苷组的CD80、CD86、CDllc、MHC-Ⅱ类分子表达水平均明显高于空白对照组,分泌IL-2、IL-10、IL-12能力比空白对照组增加,吞噬FITC-dextran的能力下降,并可促进同种异基因T细胞的增殖。说明淫羊藿苷可以促进体外培养的小鼠髓源DC的成熟,促进DC诱导的免疫应答启动。
