Overview
Ferroptosis Biology
What is Ferroptosis?
Ferroptosis is a non-apoptotic cell death process characterized by:
Iron-dependent accumulation of lipid reactive oxygen species (ROS)
Glutathione peroxidase 4 (GPX4) inactivation
Lipid peroxidation of membrane phospholipids
Distinct morphological features (no nuclear fragmentation)
Key Pathways
GPX4-dependent pathway:
GPX4 reduces lipid peroxides to prevent ferroptosis
System Xc- imports cystine for glutathione synthesis
Glutathione is required for GPX4 function
Iron metabolism:
Iron catalyzes Fenton reactions generating [ROS](/entities/reactive-oxygen-species)
Ferritin stores iron to prevent toxicity
Transferrin receptor regulates iron uptake
Therapeutic Applications
Alzheimer's Disease
Ferroptosis contributes to:
Neuronal death in AD brain
Iron accumulation in AD brain
Lipid peroxidation in [neurons](/entities/neurons)
Inhibitors may:
Protect neurons from death
Reduce oxidative damage
Slow disease progression
Parkinson's Disease
Ferroptosis in PD:
Iron accumulation in substantia nigra
Dopaminergic neuron vulnerability
Lipid peroxidation in PD brain
Inhibitors show:
Protection of dopaminergic neurons
Reduced iron-induced toxicity
Improved motor function
Huntington's Disease
Ferroptosis in HD:
Mutant [huntingtin](/proteins/huntingtin-protein) affects iron metabolism
The study of Ferroptosis Inhibitors has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
