Abstract

The sleep-wake cycle regulates interstitial fluid (ISF) and cerebrospinal fluid (CSF) levels of β-amyloid (Aβ) that accumulates in Alzheimer's disease (AD). Furthermore, chronic sleep deprivation (SD) increases Aβ plaques. However, tau, not Aβ, accumulation appears to drive AD neurodegeneration. We tested whether ISF/CSF tau and tau seeding and spreading were influenced by the sleep-wake cycle and SD. Mouse ISF tau was increased ~90% during normal wakefulness versus sleep and ~100% during SD. Human CSF tau also increased more than 50% during SD. In a tau seeding-and-spreading model, chronic SD increased tau pathology spreading. Chemogenetically driven wakefulness in mice also significantly increased both ISF Aβ and tau. Thus, the sleep-wake cycle regulates ISF tau, and SD increases ISF and CSF tau as well as tau pathology spreading.

摘要

睡眠-觉醒周期调节β-淀粉样蛋白(Aβ)在阿尔茨海默病(AD)中的细胞外液(ISF)和脑脊液(CSF)水平。此外,慢性睡眠剥夺(SD)会增加 Aβ斑块。然而,似乎是 tau 而不是 Aβ 的积累导致了 AD 的神经退行性变。我们测试了睡眠-觉醒周期和 SD 是否会影响 ISF/CSF tau 和 tau 播散。与睡眠相比,正常觉醒时小鼠 ISF tau 增加了约 90%,而 SD 时增加了约 100%。人类 CSF tau 在 SD 期间也增加了超过 50%。在 tau 播散模型中,慢性 SD 增加了 tau 病理学的播散。化学诱导的小鼠清醒也显著增加了 ISF Aβ 和 tau。因此,睡眠-觉醒周期调节 ISF tau,SD 增加 ISF 和 CSF tau 以及 tau 病理学的播散。
