【摘要】 目的探讨融合蛋白FADDDEL-GFP在胰岛细胞移植治疗1型糖尿病中的作用。方法将重组子FADDDEL-GFP导入胰岛细胞NIT-1,检测基因转染前后胰岛细胞分泌胰岛素的水平。用STZ诱导1型糖尿病模型小鼠,将FADDDEL-GFP修饰的NIT-fg细胞移植于糖尿病小鼠,检测胰岛细胞移植后对糖尿病小鼠的影响。结果转染重组子FADDDEL-GFP的NIT-1可见绿色荧光蛋白表达;移植NIT-fg细胞的糖尿病小鼠血糖降至正常,生存期延长,与对照组有明显差异。结论FADDDEL-GFP可增强机体抗同种移植排斥反应的能力。更多还原

【Abstract】 Objective To study the effect of fusion protein FADDDEL-GFP in the treatment of type 1 diabetes by murine islet cell transplantion.Methods After transfecting the recombinate FADDDEL-GFP into mouse insulinoma cells NIT-1,insulin level secreted by the cells was examined.Type 1 diabetes was induced by STZ as animal model.NIT-fg cells,the NIT-1 cells modified by FADDDEL-GFP,were transplanted into the diabetic mice.Then the effects of islet cell transplantation on diabetic mice were checked.Results GFP was expressed in NIT-1 cells transfected with FADDDEL-GFP.Diabetic mice reached normoglycemia and prolonged the life span,which was obviously different from the control group.Conclusion FADDDEL-GFP may enhance the capability of resisting allogeneic transplantation rejection.更多还原
