Research progress of pyroptosis in respiratory diseases

Pyroptosis is a programmed death mode dependent on Caspase-1/4/5/11, which is caused by activation of inflammasome, accompanied by cell membrane rupture, pore formation and cell content release. As a new type of cell death, it is widely involved in respiratory diseases, such as pulmonary fibrosis, acute lung injury, bronchopulmonary dysplasia, chronic obstructive pulmonary disease and asthma. This article reviews the mechanism of pyroptosis and its role in different respiratory diseases, in order to provide new ideas for the treatment of respiratory diseases.
