NOD样受体热蛋白结构域3(NLRP3)炎症小体是核酸结合的寡聚化结构域样受体(NLR)炎性通路中的重要组成部分,由NLRP3支架、凋亡相关斑点样蛋白(ASC)和含半胱氨酸的天冬氨酸蛋白水解酶-1前体(pro-Caspase-1)组成,激活的NLRP3炎症小体通过促进含半胱氨酸的天冬氨酸蛋白水解酶-1(Caspase-1)、白细胞介素-1β(IL-1β)、白细胞介素-18(IL-18)等关键下游细胞因子的产生和分泌,增强炎症反应,以维持机体的固有免疫和特异性免疫。研究显示,NLRP3炎症小体可影响动脉粥样硬化、免疫性疾病、炎症性疾病等多种类型疾病的进程,是目前研究最为广泛的炎性小体,已成为近年来的研究热点。文章从炎症反应机制角度出发,主要探讨NLRP3炎症小体的激活对动脉粥样硬化的调控作用。 |

Abstract: |
Nod-like receptor protein 3(NLRP3) inflammasome is an important component of NLR inflammatory pathway,which is composed of NLRP3 scaffold,ASC(apoptosis-associated speck-like protein containing CARD) and pro-Caspase-1. The activated NLRP3 inflammasome can enhance the inflammatory response by promoting the production and secretion of key downstream cytokines,such as Caspase-1,interleukin-1β(IL-1β),IL-18(interleukin-18),and so on. Thus,the inherent immunity and specific immunity of the body could be maintained. Studies have shown that NLRP3 inflammasome,as the most widely studied inflammasome and the cytokines that can affect the progress of atherosclerosis,immune diseases,inflammatory diseases and other types of diseases,has become a research hotspot in recent years. This article mainly discusses the regulatory effect of the activated NLRP3 inflammasome in atherosclerosis from the mechanisms of inflammatory response. |
