Gasdermin D:The killer protein performs cell pyroptosis / 医学研究生学报

Pyroptosis is a novel programmed cell death mode mediated by inflammatory Caspase,which has a proinflammatory effect and is accompanied by cell membrane rupture and disintegration.In recent years,researchers found that the substrate of inflam-matory Caspase-Gasdermin D(GSDMD)protein,is the key"killer protein"to execute cell pyroptosis.The inflammatory Caspase spe-cifically cleaves the GSDMD protein,forming the N-terminal domain and the C-terminal domain,and eventually results in cell pyropto-sis by protein pores formation.This article focuses on the research progress of cell pyroptosis,the structural features of GSDMD protein, and the mechanism of GSDMD protein participating in the pyroptosis and the disease models.
