哺乳动物下丘脑的视交叉上核(SCN)是主要的昼夜节律起搏器。SCN的单个细胞能够彼此独立运作,因此必须通过细胞间偶联形成一个有凝聚力的昼夜节律网络。SCN的网络特性导致其神经元和神经元亚群之间的昼夜节律协调。越来越多的证据表明SCN内存在多个相互连接的振荡器,在本综述中,我们将重点介绍我们对细胞和网络级SCN时钟的复杂组织和功能的理解的最新进展。了解SCN中细胞之间实现同步的方式,将有助于深入了解这个重要的细胞核如何在整个生物体中协调昼夜节律。
The suprachiasmatic nucleus (SCN) of the hypothalamus is the site of the master circadian pacemaker in mammals. The individual cells of the SCN are capable of functioning independently from one another and therefore must form a cohesive circadian network through intercellular coupling. The network properties of the SCN lead to coordination of circadian rhythms among its neurons and neuronal subpopulations. There is increasing evidence for multiple interconnected oscillators within the SCN, and in this Review, we will highlight recent advances in our understanding of the complex organization and function of the cellular and network-level SCN clock. Understanding the way in which synchrony is achieved between cells in the SCN will provide insight into the means by which this important nucleus orchestrates circadian rhythms throughout the organism.
