Plasma Thiols Levels in Alzheimer's Disease Mice under Diet-Induced Hyperhomocysteinemia: Effect of S-Adenosylmethionine and Superoxide-Dismutase Supplementation

Widely confirmed reports were published on association between hyperhomocysteinemia, B vitamin deficiency, oxidative stress, and amyloid-β in Alzheimer's disease (AD). Homocysteine, cysteine, cysteinylglycine and glutathione are metabolically interrelated thiols that may be potential indicators of health status and disease risk; they all participate in the metabolic pathway of homocysteine. Previous data obtained in one of our laboratories...
