大约30年前,观察到一种新形式的促炎性溶解性细胞死亡,称为细胞凋亡。仅在2015年,gasdermins被定义为在质膜上产生孔并驱动细胞凋亡的分子。今天,我们知道gasdermin介导的死亡是细菌,酵母和哺乳动物中重要的抗菌防御机制,因为它破坏了病原体复制的细胞内生态位。然而,过度和不受控制的细胞死亡也有助于几种慢性炎性疾病,包括关节炎的免疫病理学。在这篇综述中,我们讨论了最近的研究结果,其中焦亡有助于组织损伤和炎症,主要集中在损伤引起的和自身免疫性关节炎。我们还审查了新的功能和调控机制的pyroptotic执行gasdermins。最后,我们讨论了可能的模型如何pyroptosis可能有助于成纤维细胞和巨噬细胞之间的串扰,以及如何通过调节炎性小体激活和pyroptosis诱导这种串扰可以调节炎症。
About thirty years ago, a new form of pro-inflammatory lytic cell death was observed and termed pyroptosis. Only in 2015, gasdermins were defined as molecules that create pores at the plasma membrane and drive pyroptosis. Today, we know that gasdermin-mediated death is an important antimicrobial defence mechanism in bacteria, yeast and mammals as it destroys the intracellular niche for pathogen replication. However, excessive and uncontrolled cell death also contributes to immunopathology in several chronic inflammatory diseases, including arthritis. In this review, we discuss recent findings where pyroptosis contributes to tissue damage and inflammation with a main focus on injury-induced and autoimmune arthritis. We also review novel functions and regulatory mechanisms of the pyroptotic executors gasdermins. Finally, we discuss possible models of how pyroptosis may contribute to the cross-talk between fibroblast and macrophages, and also how this cross-talk may regulate inflammation by modulating inflammasome activation and pyroptosis induction.
