细胞内活性氧(ROS)的产生通常与蛋白质和DNA的损伤、毒性和死亡有关。然而,ROS也是信号的重要调节者,与氧化还原敏感蛋白协同工作,在应激过程中调节细胞的动态平衡。在这篇综述中,我们主要关注吞丝分裂的氧化还原调节,这一过程有助于能量张力以及线粒体的形态和功能。有丝分裂症越来越多地与帕金森氏症、肌萎缩侧索硬化症和癌症等疾病有关。尽管这些疾病状态使用不同的基因突变,但它们共享氧化还原失调和自噬信号的共同因素。该综述重点介绍了氧化还原敏感的信号分子,它们可以通过促进时间和空间控制的自噬信号和有丝分裂吞噬来提高神经元的存活率。
Production of cellular reactive oxygen species (ROS) is typically associated with protein and DNA damage, toxicity, and death. However, ROS are also essential regulators of signaling and work in concert with redox-sensitive proteins to regulate cell homeostasis during stress. In this review, we focus on the redox regulation of mitophagy, a process that contributes to energetic tone as well as mitochondrial form and function. Mitophagy has been increasingly implicated in diseases including Parkinson’s, Amyotrophic Lateral Sclerosis, and cancer. Although these disease states employ different genetic mutations, they share the common factors of redox dysregulation and autophagic signaling. This review highlights key redox sensitive signaling molecules which can enhance neuronal survival by promoting temporally and spatially controlled autophagic signaling and mitophagy.
