摘要

The landscape of regulated cell death (RCD) has expanded substantially over the past decade, extending beyond the classic apoptosis–necrosis dichotomy to encompass a diverse array of lytic modalities, including pyroptosis, necroptosis, and ferroptosis. These pathways are generally defined by distinct biochemical executioners, such as caspases, gasdermins, or MLKL, which coordinate the loss of plasma membrane integrity. Despite these advances, how cells integrate metabolic stress with innate immune signaling to commit to lytic death has remained an unresolved question. In a recent issue of Cell, Wang et al. report a previously unrecognized lytic cell death modality termed mitoxyperilysis, in which plasma membrane rupture is driven not by canonical enzymatic effectors but by a physical, mitochondria-mediated oxidative attack.
