Ferroptosis: Iron-Driven Cell Death in Aging Tissues

There's a new player in cell death — and it's driven by iron.
Ferroptosis is an iron-dependent, lipid peroxidation-driven form of regulated cell death. Unlike apoptosis or necrosis, it's triggered by redox imbalance and suppressed by glutathione peroxidase 4 (GPX4).
With age, iron accumulates in tissues while antioxidant defenses decline. Could ferroptosis be an underappreciated driver of age-related tissue loss?
