摘要
目的 :研究葡萄糖转运蛋白 1(glucose transportor1,GL UT1)在肾小球系膜细胞上的表达与功能 ,探讨其在糖尿病肾病发病机制中的作用。  方法 :GL UT1m RNA、蛋白质表达及其功能的检测分别采用 RT- PCR,细胞免疫荧光染色 ,流式细胞仪分析技术 ,2 - Deoxy- [3 H]- D- Glu-cose摄入法与根皮素竞争性抑制实验。  结果 :证实小鼠肾小球系膜细胞有 GL UT1m RNA和蛋白质的表达并肯定了系膜细胞上 GL UT1的功能及其在系膜细胞葡萄糖摄入中的作用。  结论 :小鼠系膜细胞存在功能性 GL UT1的表达 ,它是系膜细胞上主要的葡萄糖转运体。
