Targeting glutathione peroxidase 4 in ferroptosis: from immune regulation to pharmacological development and translational applications
Glutathione peroxidase 4 (GPX4) is a selenocysteine (Sec)-containing antioxidant enzyme and the only known mammalian enzyme capable of directly reducing membrane-embedded phospholipid and cholesterol hydroperoxides. It is recognized as a central regulator of ferroptosis, modulating cellular redox balance and influencin...
