Zhang and colleagues identify a role for cell death by glutathione peroxidase 4 (GPX4)-regulated ferroptosis in neutrophils from patients with systemic lupus erythematosus, which is triggered by type I interferons and autoreactive antibodies and contributes to lupus pathogenesis. Inhibiting accumulation of oxidative mediators by GPX4 suppresses ferroptosis.
