Inflammatory caspases drive a lytic form of cell death called pyroptosis in response to microbial infection and endogenous damage-associated signals. Two studies now demonstrate that cleavage of the substrate gasdermin D by inflammatory caspases necessitates eventual pyroptotic demise of a cell.
炎症性半胱天冬酶可驱动一种称为细胞焦亡的溶解性细胞死亡形式,以应对微生物感染和内源性损伤相关信号。现在有两项研究表明,炎症性半胱天冬酶对底物gasdermin D的切割必然导致细胞最终发生焦亡。
