Abstract: Pyroptosis is a new type of programmed cell death that is specific to caspace-1. Associated stimuli activate inflammatory corpuscles and initiate pyroptosis, leading to cell death and the release of inflammatory factor IL-1β and IL-18. Pyroptosis mediates the axial pathological changes of "pyroptosis-inflammatory response-fibrosis" in many kinds of fibrosis diseases, expands inflammatory cascade reaction, and exacerbates the course of tissue fibrosis. Therefore, the initiation of cell pyroptosis has gradually become a new direction of drug target.

Key words: Pyroptosis, Inflammasome, GSDMD, Tissue fibrosis
