Disulfide Stress Targets Modulators of Excitotoxicity in Otherwise Healthy Brains

Oxidative stress is a long-hypothesized cause of diverse neurological and psychiatric disorders but the pathways by which physiological redox perturbations may detour healthy brain development and aging are unknown. We reported recently (Foley et al., Neurochem Res 39:2030-2039, 2014) that two-electron oxidations, to disulfides, of protein vicinal thiols can vary markedly in association with more modest oxidations of the glutathione redox couple...
