Abstract

Sleep is a fundamental conserved physiological state across evolution, suggesting vital biological functions that are yet to be fully clarified. However, our understanding of the neural and molecular basis of sleep regulation has increased rapidly in recent years. Among various processes implicated in controlling sleep homeostasis, a bidirectional relationship between sleep and oxidative stress has recently emerged. One proposed function of sleep may be the mitigation of oxidative stress in both brain and peripheral tissues, contributing to the clearance of reactive species that accumulate during wakefulness. Conversely, reactive species, such as reactive oxygen species (ROS) and reactive nitrogen species (RNS), at physiological levels, may act as signaling agents to regulate redox-sensitive transcriptional factors, enzymes, and other effectors involved in the regulation of sleep. As a primary sensor of intracellular oxidation, the transcription factor NRF2 is emerging as an indispensable component to maintain cellular redox homeostasis during sleep. Indeed, a number of studies have revealed an association between NRF2 dysfunction and the most common sleep conditions, including sleep loss, obstructive sleep apnea, and circadian sleep disturbances. This review examines the evidence of the intricate link between oxidative stress and NRF2 function in the context of sleep, and highlights the potential of NRF2 modulators to alleviate sleep disturbances.

睡眠与氧化应激:关于 NRF2 作用的当前观点。
睡眠是一种在进化过程中保持不变的基本生理状态,其重要的生物学功能尚待完全阐明。然而,近年来我们对睡眠调控的神经和分子基础的了解迅速加深。在控制睡眠平衡的各种过程中,最近出现了睡眠与氧化应激之间的双向关系。睡眠的一个功能可能是减轻大脑和外周组织的氧化应激,有助于清除清醒时积累的活性物质。相反,活性氧(ROS)和活性氮(RNS)等活性物质在生理水平上可作为信号媒介,调节氧化还原敏感的转录因子、酶和其他参与睡眠调节的效应因子。作为细胞内氧化的主要传感器,转录因子 NRF2 正在成为睡眠期间维持细胞氧化还原平衡不可或缺的组成部分。事实上,许多研究已经揭示了 NRF2 功能障碍与最常见的睡眠状况(包括睡眠不足、阻塞性睡眠呼吸暂停和昼夜节律睡眠紊乱)之间的关联。本综述探讨了氧化应激与 NRF2 功能在睡眠中的复杂联系,并强调了 NRF2 调节剂在缓解睡眠障碍方面的潜力。

期刊介绍: Cellular and Molecular Neurobiology publishes original research concerned with the analysis of neuronal and brain function at the cellular and subcellular levels. The journal offers timely, peer-reviewed articles that describe anatomic, genetic, physiologic, pharmacologic, and biochemical approaches to the study of neuronal function and the analysis of elementary mechanisms. Studies are presented on isolated mammalian tissues and intact animals, with investigations aimed at the molecular mechanisms or neuronal responses at the level of single cells. Cellular and Molecular Neurobiology also presents studies of the effects of neurons on other organ systems, such as analysis of the electrical or biochemical response to neurotransmitters or neurohormones on smooth muscle or gland cells.
