摘要: 目的 分析1型糖尿病调节性T细胞及CD4+效应性T细胞数和相关细胞因子IL-2、 IL-10、IL-17和IFN-gamma mRNA表达的表达。方法 1型糖尿病患者45例、2型糖尿病患者(年龄≤45岁,病程≤5年,BMI≤30kg/m2)37例、正常人35例。收集受试者临床资料和外周血样本。用流式细胞分析法检测Treg和CD4+Teff细胞数,real time-PCR法检测IL-2、 IL-10、IL-17和IFN-gamma mRNA表达。结果 T1DM组Treg细胞/CD3+CD4+细胞比例与IFN-gamma相对表达量成负相关(rs=-0.678,P=0.001);Treg细胞/CD3+CD4+细胞比例与IL-10表达量成正相关(rs=0.773,p<0.001)。结论 T1DM中保护性因素和破坏性因素平衡打破,以IL-10和IFN-gamma失衡为重要表现。

Abstract: Objective Analyze and compare the amount of regulatory T cell and CD4+effector T cell, expression of IL-2, IL-10, IL17 and IFN-gamma in patients with type 1 diabetes (T1DM).Methods 45 T1DM, 37 T2DM patients (age ≤45 years, duration of the disease≤5 years, BMI≤30kg/m2) and 35 healthy subjects were involved. The amount of regulatory T cell and CD4+ effector T cell was analyzed by flow cytometry. Expression of cytokines such as IL-2, IL-10, IL17 and IFN-gamma were measured by real time-qPCR. Results There was negative correlation between Treg percentage and IFN-gamma expression in T1DM group (rs=-0.678, P=0.001). Positve correlation between Treg percentage and IL-10 expression was viewed in T1DM group (rs=0.773,p<0.001). Conclusion Out-of-balance of IL-10 and IFN-gamma in type 1 diabetes group suggested that the balance between preventive and destructive factors was broken.
