除了其在蛋白质合成中的重要作用外,半胱氨酸在氧化还原稳态中起着至关重要的作用,是主要抗氧化剂谷胱甘肽的组成部分,本身也是一种有效的抗氧化剂。此外,半胱氨酸经历多种翻译后修饰,其调节若干生理过程。越来越清楚的是,氧化还原调节的事件不仅在外周组织中而且在半胱氨酸处置对这些途径至关重要的大脑中发挥重要作用。半胱氨酸代谢失调与几种神经退行性疾病有关。因此,恢复半胱氨酸平衡具有治疗益处。这篇综述讨论了在正常和病理条件下大脑中半胱氨酸分布的代谢信号通路,重点介绍了衰老和神经退行性疾病(如亨廷顿病和钼辅因子缺乏症等)中半胱氨酸代谢的最新研究结果。
Besides its essential role in protein synthesis, cysteine plays vital roles in redox homeostasis, being a component of the major antioxidant glutathione and a potent antioxidant by itself. In addition, cysteine undergoes a variety of post-translational modifications which modulate several physiological processes. It is becoming increasingly clear that redox modulated events play important roles not only in peripheral tissues but also in the brain where cysteine disposition is central to these pathways. Dysregulated cysteine metabolism is associated with several neurodegenerative disorders. Accordingly, restoring cysteine balance has therapeutic benefits. This review discusses metabolic signaling pathways pertaining to cysteine disposition in the brain during normal and pathological conditions highlighting recent findings on cysteine metabolism during aging and in neurodegenerative conditions such as Huntington’s disease and molybdenum cofactor deficiency among others.
