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

Reduction of molecular oxygen by redox active thiols: comparison of glutathione, N-acetylcysteine, cysteine, and homocysteine

This in vitro study compared the redox activity of four thiol compounds—glutathione (GSH), N-acetylcysteine (NAC), cysteine (Cys), and homocysteine (HCS)—to evaluate their potential to reduce molecular oxygen and influence oxidative or reductive stress. The researchers found that GSH and Cys can reduce O₂ to generate reactive oxygen species (ROS), particularly
