The Role of Ferroptosis in Nervous System Disorders

Abstract

Ferroptosis is distinct from other apoptotic forms of programmed cell death and is characterized by the accumulation of iron and lipid peroxidation. Iron plays a crucial role in the oxidation of lipids via the Fenton reaction with oxygen. Hence, iron accumulation causes phospholipid peroxidation which induces ferroptosis. Moreover, detoxification by glutathione is disrupted during ferroptosis. A growing number of studies have implicated ferroptosis in nervous system disorders such as depression, neurodegenerative disease, stroke, traumatic brain injury, and sepsis-associated encephalopathy. This review summarizes the pathogenesis of ferroptosis and its relationship with various nervous system disorders.
