Ferroptosis is a type of cell death process defined by iron-dependent peroxidation of phospholipids leading to the destruction of cellular membranes and death of the cell. Ferroptosis occurs throughout the body, but a considerable research focus on ferroptosis in the brain — neuroferroptosis — has been driven by the rich lipid and iron content of the brain as well as its high oxygen consumption. Neurons also have an exceptionally large surface area and metabolic demand, which necessitates specific mechanisms (such as lipid antioxidants) to engage constantly to protect the plasma membrane against lipid peroxidation. Ferroptosis has been extensively linked to neurodegeneration and ischaemia and is increasingly implicated in physiological processes such as neuronal reprogramming. Astrocytes provide metabolic support to neurons, enabling them to defend against ferroptosis, yet ferroptotic signals in microglia can propagate damage to astrocytes and neurons, highlighting the complex int

The brain’s high lipid content, iron levels and oxygen metabolism uniquely predispose it to ferroptosis, an iron-dependent form of regulated cell death. In this Review, Lei et al. discuss brain-specif...
