睡眠是一种进化上保守的行为,人们越来越认识到睡眠对人类健康的重要性。虽然其确切功能仍有争议,但睡眠已被认为在各种生物现象中发挥关键作用,从突触可塑性到代谢清除。虽然很明显,睡眠是由生物钟调节的,但这是如何发生的仍然是个谜。在这里,我们研究了生物钟调节睡眠的遗传机制,借鉴了最近在果蝇、斑马鱼、老鼠和人类身上的研究成果。这些研究表明,中央和局部时钟利用不同的机制来调节睡眠的不同方面,更好地理解这种多层调节可能会导致更好地理解睡眠的功能。
Sleep is an evolutionarily conserved behavior that is increasingly recognized as important for human health. While its precise function remains controversial, sleep has been suggested to play a key role in a variety of biological phenomena, ranging from synaptic plasticity to metabolic clearance. Although it is clear that sleep is regulated by the circadian clock, how this occurs remains enigmatic. Here, we examine the genetic mechanisms by which the circadian clock regulates sleep, drawing upon recent work in fruit flies, zebrafish, mice, and humans. These studies reveal that central and local clocks utilize diverse mechanisms to regulate different aspects of sleep, and a better understanding of this multilayered regulation may lead to a better understanding of the function(s) of sleep.
