所有动物物种的睡眠保护表明,睡眠具有重要的功能。我们在这里报告说,睡眠在确保代谢平衡方面具有关键作用。使用实时评估四甲基铵扩散和双光子成像在活的小鼠,我们表明,自然睡眠或麻醉与60%的间隙空间增加,导致脑脊液与间质液的对流交换显着增加。反过来,间质液的对流流量增加了睡眠期间β-淀粉样蛋白的清除率。因此,睡眠的恢复功能可能是增强清除在清醒的中枢神经系统中积累的潜在神经毒性废物的结果。
The conservation of sleep across all animal species suggests that sleep serves a vital function. We here report that sleep has a critical function in ensuring metabolic homeostasis. Using real-time assessments of tetramethylammonium diffusion and two-photon imaging in live mice, we show that natural sleep or anesthesia are associated with a 60% increase in the interstitial space, resulting in a striking increase in convective exchange of cerebrospinal fluid with interstitial fluid. In turn, convective fluxes of interstitial fluid increased the rate of β-amyloid clearance during sleep. Thus, the restorative function of sleep may be a consequence of the enhanced removal of potentially neurotoxic waste products that accumulate in the awake central nervous system.
