Oxidative stress, a condition characterized by an imbalance between reactive oxygen species (ROS) production and the body's ability to detoxify them, has emerged as a pivotal factor in the pathophysiology of various diseases. Red blood cells (RBCs), essential components of the circulatory system, are particularly susceptible to oxidative damage due to their high oxygen-carrying capacity and the abundance of vulnerable biomolecules. This review comprehensively explores the intricate mechanisms underlying oxidative stress-induced damage to red blood cells and the subsequent implications for overall health and disease. We delve into the sources of ROS generation within RBCs, including metabolic processes and external factors, shedding light on the delicate redox balance that governs cellular homeostasis. The impact of oxidative stress on red blood cells extends beyond the confines of their primary physiological role, as these cells actively participate in immune responses, inflammation modulation, and nitric oxide metabolism. Consequently, understanding the implications of oxidative stress on RBCs provides valuable insights into the broader landscape of health and disease. In conclusion, this review underscores the critical role of oxidative stress in influencing red blood cell physiology and its far-reaching implications for human health. Elucidating the molecular intricacies of this relationship not only enhances our understanding of fundamental biological processes but also paves the way for the development of targeted therapeutic interventions to mitigate the adverse effects of oxidative stress on red blood cells and, by extension, on overall health.
氧化应激是一种活性氧(ROS)产生与机体解毒能力失衡的状态,已成为各种疾病病理生理学的关键因素。红细胞(RBC)作为循环系统的重要组成部分,由于其高携氧能力和丰富的易损生物分子,特别容易受到氧化损伤。本综述全面探讨了氧化应激诱导红细胞损伤的复杂机制及其对整体健康和疾病的后续影响。我们深入研究了 RBC 内 ROS 产生的来源,包括代谢过程和外部因素,阐明了控制细胞内稳态的精细氧化还原平衡。氧化应激对红细胞的影响超出了其主要生理作用的范围,因为这些细胞积极参与免疫反应、炎症调节和一氧化氮代谢。因此,了解氧化应激对 RBC 的影响为我们深入了解健康和疾病的广阔领域提供了有价值的见解。总之,本综述强调了氧化应激在影响红细胞生理学及其对人类健康的深远影响方面的关键作用。阐明这种关系的分子复杂性不仅增强了我们对基本生物学过程的理解,还为开发靶向治疗干预措施铺平了道路,以减轻氧化应激对红细胞的不良影响,进而对整体健康产生影响。
