摘要: 炎性体是一种大分子多蛋白复合体,是固有免疫的重要组成成分。核苷酸结合寡聚化结构域受体蛋白3NLRP3)炎性体是目前被研究得最多的炎性体。NLRP3炎性体由NLRP3、凋亡相关斑点样蛋白(ASC)及pro-半胱氨酸天冬氨酸特异性蛋白酶(caspase-1组成。当细胞受到刺激时,NLRP3被激活并能够通过结合蛋白ASC招募procaspase-1,形成NLRP3炎性体。在NLRP3炎性体的作用下,pro-caspase-1被激活成为caspase-1,最终导致白细胞介素(IL-1βIL-18的成熟与分泌,引起一系列炎症反应。NLRP3炎性体在动脉粥样硬化、2型糖尿病、癌症等多种疾病中有重要作用,并且越来越多的证据表明NLRP3炎性体亦在心肌缺血再灌注损伤中发挥重要作用。本文介绍了NLRP3炎性体的基本结构和功能,并综述了NLRP3炎性体在心肌缺血再灌注损伤中作用的研究进展。

Abstract: Inflammasome is a multi-protein complex, which is a crucial constituent of innate immunity. NLRP3
inflammasome is the most extensively studied one. NLRP3 is composed of NLRP3, apoptosis associated spot like protein
(ASC) and pro-cysteine aspartate specific protease (caspase) - 1. When cells are stimulated, NLRP3 is activated and can
recruit pro-caspase-1 through the binding protein ASC to form NLRP3 inflammasome. Under the action of NLRP3
inflammasome, pro-caspase-1 is activated to caspase-1, which eventually leads to the maturation and secretion of IL-1 β
and IL-18, causing a series of inflammatory reactions. The NLRP3 inflammasome plays an important role in atherosclerosis,
type 2 diabetes, cancer and other diseases. There has been increasing evidence that NLRP3 inflammasome also plays an
important role in heart diseases, including myocardial ischemia/reperfusion injury (MI/RI). This article briefly introduces the
basic structure and function of NLRP3 inflammasome and reviews the research progress of the role of NLRP3 inflammasome
in the pathophysiology of MI/RI.
