Structural mechanism of Gasdermin E-mediated mtDNA release from apoptotic mitochondria
During apoptosis, the permeabilization of the mitochondrial inner membrane (MIM) through still-unclear mechanisms releases mtDNA into the cytosol, triggering the inflammatory cGAS/STING pathway under low caspase activity. Here, we report that, in apoptosis, the active form of the pore-forming protein Gasdermin E (GSDME-N) damages mitochondria before plasma membrane disruption. We visualize…
