摘要
目的探讨黄芪多糖(APS)对NOD小鼠T细胞亚群的免疫调节机制。方法观察APS组和对照组NOD鼠胰岛浸润淋巴细胞免疫组化、脾T淋巴细胞CD4+/CD8+亚群比值,RT-PCR法检测两组胰岛中IL-1β、IL-2、IL-6、IL-12、TNF-α和INF-γTh1型细胞因子的mRNA表达。结果APS可以降低NOD小鼠1型糖尿病的发病率,下降胰岛浸润炎症细胞及脾脏中的CD4+/CD8+亚群比值。与对照组相比,APS组胰岛IL-1β、IL-2、IL-6、IL-12、TNF-α和INF-γ的mRNA表达水平明显下调。结论APS能纠正NOD小鼠Th1型细胞/细胞因子的免疫失衡状态,预防1型糖尿病的发生。
