So that the cell can accept enough materials … WebApr 14, 2024 · Highlights. The pore-forming family of gasdermins (GSDMs) control cellular homeostasis independent of their canonical roles in releasing IL-1β/IL-18 and promoting plasma membrane rupture during pyroptosis. Some GSDMs can associate with and form pores in mitochondria to trigger mitoDAMP release and alter cell death modality use.
