As an innate immune sensor, ZBP1 senses infections and cellular damage, triggering the formation of a PANoptosome complex containing caspase-8 and RIPKs that activates the inflammasome, drives inflammatory cell death, and produces proinflammatory cytokines; however, ZBP1’s role in mitochondrial damage was not previously known. A recent publication in Cell by Lei et al. shows that ZBP1 senses mitochondrial genome instability and forms a complex with cGAS and RIPKs to sustain type I interferon signaling and drive cardiotoxicity.
