One of the significant health issues in the world is the prevalence of ulcerative colitis (UC). UC is a chronic disorder that mainly affects the colon, beginning with the rectum, and can progress from asymptomatic mild inflammation to extensive inflammation of the entire colon. Understanding the underlying molecular mechanisms of UC pathogenesis emphasizes the need for innovative therapeutic approaches based on identifying molecular targets. Interestingly, in response to cellular injury, the NLR family pyrin domain containing 3 (NLRP3) inflammasome is a crucial part of the inflammation and immunological reaction by promoting caspase-1 activation and the release of interleukin-1β. This review discusses the mechanisms of NLRP3 inflammasome activation by various signals and its regulation and impact on UC.
世界上存在的一个重大健康问题就是溃疡性结肠炎(UC)的流行。UC 是一种慢性疾病,主要影响结肠,从直肠开始,并可能从无症状的轻度炎症发展为整个结肠的广泛炎症。了解 UC 发病机制的潜在分子机制强调了需要基于识别分子靶点的创新治疗方法。有趣的是,细胞损伤后,NLR 家族含有 pyrin 结构域的蛋白 3(NLRP3)炎性小体是通过促进半胱天冬酶-1 的激活和白细胞介素-1β的释放来促进炎症和免疫反应的关键部分。本综述讨论了各种信号对 NLRP3 炎性小体激活的机制及其调控作用和对 UC 的影响。
