摘要：

目的探讨NLRP3-ASC-Caspase-1-IL-18/IL-1β-TGF-β信号通路与初诊Ⅱ型糖尿病(T2DM)的临床相关性。方法入选符合纳入标准的健康对照组30例及T2DM组40例,收集所有研究对象的一般临床资料,采用RTqPCR检测各组患者外周单个核细胞(PBMCs)中核苷酸结合寡聚化结构域样受体蛋白3(NLRP3)炎性小体各组分mRNA的表达水平,Western blot法检测其蛋白表达水平,并采用ELISA法测定各组患者空腹血浆白介素-1β(IL-1β)、白介素-18(IL-18)、转化生长因子-β(TGF-β)水平。结果 PBMCs中NLRP3、凋亡相关微粒蛋白(ASC)、半胱氨酸蛋白酶-1(caspase-1)mRNA表达水平在T2DM组和对照组之间无显著性差异(P>0.05),但ASCmRNA在T2DM组与总胆固醇(TC)呈正相关(P<0.05);Caspase-1mRNA在T2DM组与体重指数(BMI)呈正相关(P<0.05)。PBMCs中NLRP3、ASC、Caspase-1表达水平及血浆IL-1β、IL-18、TGF-β水平在T2DM组和对照组之间有显著性差异(P<0.05),且ASC在T2DM组与平均动脉压(MAP)、空腹血糖(FPG)、TC、IL-1β、IL-18呈正相关(P<0.05);Caspase-1在T2DM组与吸烟、FPG、低密度脂蛋白胆固醇(LDL-C)、IL-1β呈正相关(P<0.05);IL-1β在T2DM组与TGF-β呈正相关(P<0.05)。结论以NLRP3炎性小体为中心的NLRP3-ASC-Caspase-1-IL-18/IL-1β-TGF-β信号通路可能在初诊T2DM的发生发展过程中发挥重要作用。
