Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Sepsis causes a high mortality rate and current treatment focuses on supportive therapies but lacks specific therapeutic targets. Notably, sirtuins (SIRTs) shows potential clinical application in the treatment of sepsis. It has been demonstrated that SIRTs, the nicotinamide adenine dinucleotide(NAD)-dependent deacetylases that regulate key signaling pathways in eukaryotes and prokaryotes, are involved in a variety of biological processes. To date, seven mammalian yeast Sir2 homologs have been identified. SIRTs can regulate inflammation, oxidative stress, apoptosis, autophagy, and other pathways that play important roles in sepsis-induced organ dysfunction. However, the existing studies on SIRTs in sepsis are too scattered, and there is no relevant literature to integrate them. This review innovatively summarizes the different mechanisms of SIRTs in sepsis organ dysfunction according to the different systems, and focuses on SIRT agonists, inhibitors, and targeted drugs that have been proved to be effective in the treatment of sepsis, so as to integrate the clinical research and basic research closely. We searched PubMed for all literature related to SIRTs and sepsis since its inception using the following medical subject headings: sirtuins, SIRTs, and sepsis. Data on the mechanisms of SIRTs in sepsis-induced organ damage and their potential as targets for disease treatment were extracted.
脓毒症定义为感染引起的宿主反应失调导致的危及生命的器官功能障碍。脓毒症导致高死亡率,目前的治疗方法侧重于支持性治疗,但缺乏特定的治疗靶点。值得注意的是,沉默调节蛋白(SIRTs)在脓毒症治疗中具有潜在的临床应用。已经证明,SIRTs 是烟酰胺腺嘌呤二核苷酸(NAD)依赖性去乙酰化酶,调节真核生物和原核生物中的关键信号通路,参与多种生物学过程。迄今为止,已经鉴定出 7 种哺乳动物酵母 Sir2 同源物。SIRTs 可以调节炎症、氧化应激、细胞凋亡、自噬和其他在脓毒症引起的器官功能障碍中起重要作用的途径。然而,目前关于脓毒症中 SIRTs 的研究过于分散,没有相关文献对其进行整合。本综述创新性地根据不同系统总结了 SIRTs 在脓毒症器官功能障碍中的不同作用机制,并重点介绍了已被证明在脓毒症治疗中有效的 SIRT 激动剂、抑制剂和靶向药物,以便将临床研究和基础研究紧密结合起来。我们使用以下医学主题词在 PubMed 上搜索了自成立以来与 SIRTs 和脓毒症相关的所有文献:沉默调节蛋白、SIRTs 和脓毒症。提取了 SIRTs 在脓毒症引起的器官损伤中的作用机制及其作为疾病治疗靶点的潜力的数据。
