Pyroptosis:Induction and inhibition strategies for immunotherapy of diseases

Cell death is a central process for organismal health.Pyroptosis,namely pyroptotic cell death,is recognized as a critical type that disrupts membrane and triggers pro-inflammatory cytokine secretion via gasdermins,providing a robust form of cytolysis.Meanwhile,along with the thorough research,a great deal of evidence has demonstrated the dual effects of pyroptosis in host defense and inflammatory diseases.More importantly,the recent identification of abundant gasdermin-like proteins in bacteria and fungi suggests an ancient origin of pyroptosis-based regulated cell death in the life evolution.In this review,we bring a general overview of pyroptosis pathways focusing on gasdermin structural biology,regulatory mechanisms,and recent progress in induction and inhibition strategies for disease treatment.We look forward to providing an insightful perspective for readers to comprehend the frame and challenges of the pyroptosis field,and to accelerating its clinical application.
