摘要

体内正电子发射断层扫描显示,阿尔茨海默病早期脑葡萄糖利用率降低,反映了神经元线粒体内氧化磷酸化基因表达的潜在可逆下调。这种下调可能发生在神经元能量需求首次因突触功能障碍或丧失而减少时。

Brain Energy Metabolism, Cognitive Function and Down-regulated Oxidative Phosphorylation in Alzheimer Disease

Reduced brain glucose utilization in early stages of Alzheimer disease, as measured within vivopositron emission tomography, reflects potentially reversible down-regulation of gene expression for oxidative phosphorylation within neuronal mitochondria. Such down-regulation may occur when neuronal energy demand is first reduced by synaptic dysfunction or loss.
