摘要
目的 探讨重组人白细胞介素 6(rhIL 6)对NOD小鼠自发性和环磷酰胺 (CY)诱发性Ⅰ型糖尿病 (IDDM)的影响及相关机制。方法 通过观察NOD小鼠用药后血糖和尿糖水平、胰腺组织病理学特征 ,及血清抗CD3抗体、LPS诱导的炎症因子IFN γ、TNF α水平的变化 ,以及CY诱导ID DM发生率 ,确定rhIL 6的抗IDDM作用。结果  4wk龄♀NOD小鼠连续注射rhIL 6 1 6wk后 ,胰岛炎即胰腺淋巴细胞、单核细胞浸润明显减少 ,糖尿病的发病率明显降低(33 % )。与空白对照组相比 ,血清中炎症因子IFN γ、TNF α水平也呈显著的下降趋势。 1 2wk龄NOD小鼠连续 8wk应用rhIL 6 ,糖尿病发生率则无明显变化 ,且实验中未观察到rhIL 6对CY诱发IDDM的保护作用。结论 rhIL 6早期预防用药可降低NOD小鼠自发性IDDM的发生 ,该保护作用可能与其降低炎症因子TNF α、IFN γ分泌有关
