代谢性疾病是由体内氨基酸、葡萄糖和脂质代谢紊乱引起的一类疾病,慢性炎症反应是其重要特征之一.Nod样受体蛋白3(Nod-like receptor protein 3,NLRP3)炎性体是位于细胞内的一种蛋白质复合体,主要功能为活化半胱氨酸天冬氨酸蛋白酶1(caspase-1)以间接调控白介素1β(IL-1β)、IL-18和IL-33等的成熟和分泌.NLRP3炎性体是炎性体相关研究的热点,多种内源性或外源性危险信号通过激活这一蛋白质复合体上调炎性因子的表达水平,从而促进多种代谢性疾病的发生发展.本文对NLRP3炎性体的结构、功能、调节以及在代谢性疾病中的作用做一综述,以期为代谢性疾病的防治提供新靶点.
【英文摘要】
Metabolic diseases are caused by amino acid, glucose and lipid metabolism disorder, chronic inflammation is one of its important characteristics. The Nod-like receptor protein 3(NLRP3) inflammasome is a protein complexes located in cellular, the main function is to activate caspase-1, and then to indirectly regulate the mature and secretion of interleukin 1β(IL-1β), IL-18 and IL-33. The NLRP3 inflammasome is a hotspot in inflammasome associated studies, a variety of endogenous or exogenous danger signals up...
