睡眠障碍与未来患阿尔茨海默病的风险有关。睡眠中断增加可溶性淀粉样蛋白-β,这表明睡眠障碍增加阿尔茨海默病风险的机制。我们在人类中测试了这种反应,使用留置腰椎导管连续采集脑脊液,同时参与者被剥夺睡眠,用羟丁酸钠治疗,或允许正常睡眠。所有参与者均输注13 C6-亮氨酸以测量淀粉样蛋白-β动力学。我们发现,与睡眠对照组相比,睡眠剥夺通过增加过夜淀粉样蛋白-β的产生,使过夜淀粉样蛋白-β-38,淀粉样蛋白-β-40和淀粉样蛋白-β-42水平增加25-30%。这些发现表明,睡眠中断通过增加淀粉样蛋白-β的产生增加阿尔茨海默病的风险。
Sleep disturbances are associated with future risk of Alzheimer’s disease. Disrupted sleep increases soluble amyloid-β, suggesting a mechanism for sleep disturbances to increase Alzheimer’s disease risk. We tested this response in humans using indwelling lumbar catheters to serially sample cerebrospinal fluid while participants were sleep-deprived, treated with sodium oxybate, or allowed to sleep normally. All participants were infused with 13C6-leucine to measure amyloid-β kinetics. We found that sleep deprivation increased overnight amyloid-β-38, amyloid-β-40, and amyloid-β-42 levels by 25–30% via increased overnight amyloid-β production relative to sleeping controls. These findings suggest that disrupted sleep increases Alzheimer’s disease risk via increased amyloid-β production.
