Parkinson's disease is characterized by dopamine cell loss of the substantia nigra. Parkinson's disease and the neurotoxin 1-methyl-4-phenyl-1,2,5,6 tetrahydropyridine may destroy dopamine neurons through oxidative stress. Coenzyme Q is a cofactor of mitochondrial uncoupling proteins that enhances state-4 respiration and eliminate superoxides. Here we report that short-term oral administration of coenzyme Q induces nigral mitochondrial uncoupling and prevents dopamine cell loss after 1-methyl-4-phenyl-1,2,5,6 tetrahydropyridine administration in monkeys.
帕金森病的特征是黑质多巴胺能细胞丢失。帕金森病和神经毒素1-甲基-4-苯基-1,2,5,6-四氢吡啶可能通过氧化应激破坏多巴胺能神经元。辅酶Q是线粒体解偶联蛋白的一种辅助因子,可增强状态4呼吸并清除超氧化物。在此我们报告,在猴子中,短期口服辅酶Q可诱导黑质线粒体解偶联,并预防1-甲基-4-苯基-1,2,5,6-四氢吡啶给药后多巴胺能细胞的丢失。
