Glutathione depletion and overproduction both initiate degeneration of nigral dopaminergic neurons

This 2011 study investigated how both glutathione (GSH) deficiency and excess affect the viability of nigral dopaminergic neurons, key cells involved in Parkinson’s disease (PD). Using a viral vector-based RNA interference model in rats, researchers modulated the synthesis of GSH by targeting glutamate–cysteine ligase subunits. Both decreased and increased GSH

Regulation of glutathione synthesis

This review explores the regulation of glutathione (GSH) synthesis, highlighting its critical role in antioxidant defense, cellular proliferation, and redox balance. The process involves two key enzymes: glutamate cysteine ligase (GCL), which catalyzes the rate-limiting step, and GSH synthase (GS), which converts γ-glutamylcysteine to GSH. GSH synthesis is tightly regulated
