The inflammasome is a platform for inflammatory signaling, and the NLRP3 inflammasome recognizes stimuli in vitro and in vivo, and releases inflammatory cytokines that trigger inflammation and pyroptosis. In the gut, the NLRP3 inflammasome is a key sensor for protecting the body from damage and exogenous pathogens. It plays a fundamental role in maintaining the stability of the gut's immune system. We focus on the role of NLRP3 as a key node in maintaining the homeostasis of gut microbiota which has not been fully highlighted in the past; gut microbiota and innate immunity, as well as the NLRP3 inflammasome, are discussed in this article.
炎症小体是炎症信号转导的平台,NLRP3 炎症小体在体外和体内识别刺激物,并释放引发炎症和细胞焦亡的炎症细胞因子。在肠道中,NLRP3 炎症小体是保护机体免受损伤和外源性病原体的关键传感器。它在维持肠道免疫系统的稳定性方面发挥着基础性作用。我们关注的是 NLRP3 作为维持肠道微生物组内稳态的关键节点的作用,这在过去并未得到充分强调;本文讨论了肠道微生物组和先天免疫以及 NLRP3 炎症小体。
