单胺氧化酶A(MAO-A)是重性抑郁症、攻击性和神经退行性疾病的病理生理学和治疗学中的重要靶点。我们在健康志愿者中用[11 C]-去氢骆驼蓬碱正电子发射断层扫描测量了MAO-A底物变化对情感和神经退行性疾病相关区域MAO-A结合的影响。前额叶皮层色氨酸耗竭后,单胺氧化酶A VT(MAO-A密度指数)降低(平均:14%±9%)(P<0.031);卡比多巴-左旋多巴给药后,纹状体单胺氧化酶A VT升高(平均:17%±11%)(P<0.007)。这些研究结果表明,MAO-A在维持单胺神经递质稳态的适应性作用,迅速补偿波动的单胺水平。
Monoamine oxidase A (MAO-A) is an important target in the pathophysiology and therapeutics of major depressive disorder, aggression, and neurodegenerative conditions. We measured the effect of changes in MAO-A substrate on MAO-A binding in regions implicated in affective and neurodegenerative disease with [11C]-harmine positron emission tomography in healthy volunteers. Monoamine oxidase A VT, an index of MAO-A density, was decreased (mean: 14%±9%) following tryptophan depletion in prefrontal cortex (P<0.031), and elevated (mean: 17%±11%) in striatum following carbidopa–levodopa administration (P<0.007). These findings suggest an adaptive role for MAO-A in maintaining monoamine neurotransmitter homeostasis by rapidly compensating fluctuating monoamine levels.
