洛美利嗪对大鼠脑微血管内皮细胞上P-糖蛋白功能的影响

Effect of Lomerizine on the Activity of P-glycoprotein in Primary Cultured Rat Brain Microvessel Endothelial Cells

  • 摘要: 目的:研究洛美利嗪对大鼠脑微血管内皮细胞上P-糖蛋白功能的影响。方法:使用荧光分光光度计和流式细胞术分析大鼠脑微血管内皮细胞内P-糖蛋白底物-罗丹明123的荧光强度。结果:环孢素A和洛美利嗪与大鼠脑微血管内皮细胞孵育后能明显提高胞内罗丹明123的荧光强度。人脐静脉内皮细胞内荧光强度则不受环孢素A和洛美利嗪的影响。结论:洛美利嗪能显著地抑制大鼠脑微血管内皮细胞上P-糖蛋白的活性,提高P-糖蛋白底物的胞内浓度。
