摘要
细胞焦亡是一种新发现的细胞程序性死亡方式,兼有凋亡和坏死的特征。细胞焦亡的效应蛋白是Gasdermin-D,细胞受到刺激后,焦亡相关Caspases活化,水解Gasdermin-D,产物Gasdermin-D-N端结合到细胞膜上形成穿孔,造成细胞渗透性死亡、溶解,即发生焦亡,这个过程中伴随炎症因子的释放。本文就细胞焦亡的形态学特点、分子机制及其在病毒感染发病中作用的研究进展进行综述。
Pyroptosis is a newly discovered form of programmed cell death, and morphologically, it has the characteristics of both necrosis and apoptosis. Gasdermin-D is the executive protein in pyroptosis. Pyroptosis-related caspases were activated in cells after stimulation, and then caspases hydrolyzed to gasdermin-D. Subsequently, gasdermin-N domain combined to cytomembrane to form membrane pores. The pores disrupt the osmotic potential and cause cell swelling and eventual lysis. The process was also accompanied by releasing of inflammatory cytokines. This review focused on the morphology, molecular mechanism of pyroptosis and its role in viral infections.
