Abstract
Purpose
To review the role of ferroptosis, an iron-dependent form of regulated cell death, in chronic obstructive pulmonary disease (COPD), and to explore the therapeutic opportunities of iron chelators in mitigating ferroptosis-driven lung injury.
Methods
We performed a structured search of PubMed, Scopus, and Web of Science from inception to Dec 31, 2024, using the terms “ferroptosis,” “iron homeostasis,” “iron chelators,” “lipid peroxidation,” and “COPD.” Of the 86 records identified, 45 met the predefined criteria (relevance to pulmonary iron metabolism, ferroptotic mechanisms, and therapeutic interventions) and were included in the narrative synthesis.
Results
Dysregulated iron handling in COPD leads to increased labile iron pools in airway epithelial cells and alveolar macrophages, promoting Fenton chemistry, reactive oxygen species generation, and lipid peroxidation cascades, which trigger ferroptosis. Classical iron chelators, such as deferoxamine, deferiprone, and deferasirox, have shown efficacy in preclinical models by sequestering redox-active iron and preserving mitochondrial integrity. Novel synthetic chelators and nanoparticle-based delivery systems offer lung-specific iron removal with improved safety. The integration of trace-element biomarkers, including serum ferritin, hepcidin, transferrin saturation, and lipid peroxidation products, provides potential tools for patient stratification and therapy monitoring.
Conclusion
Targeting iron dysregulation and ferroptosis through advanced chelation strategies holds promise as a novel therapeutic approach for COPD. Combining mechanistic insights with precision delivery technologies may enhance treatment efficacy and improve clinical outcomes by mitigating iron-driven oxidative lung injuries.
目的探讨铁中毒(一种铁依赖性的细胞死亡形式)在慢性阻塞性肺疾病(COPD)中的作用,并探讨铁螯合剂在减轻铁中毒引起的肺损伤中的治疗机会。方法我们对PubMed、Scopus和Web of Science从成立到2024年12月31日进行了结构化搜索,使用术语“铁中毒”、“铁稳态”、“铁螯合剂”、“脂质过氧化”和“COPD”。在确定的86例记录中,45例符合预先确定的标准(与肺铁代谢相关,铁下沉机制和治疗干预),并被纳入叙述综合。结果慢性阻塞性肺病患者铁处理失调导致气道上皮细胞和肺泡巨噬细胞中不稳定铁池增加,促进Fenton化学、活性氧生成和脂质过氧化级联反应,从而引发铁死亡。经典的铁螯合剂,如去铁胺、去铁素和去铁素,通过隔离氧化还原活性铁和保持线粒体完整性,在临床前模型中显示出疗效。新型合成螯合剂和纳米颗粒为基础的输送系统提供肺特异性铁去除与提高安全性。微量元素生物标志物的整合,包括血清铁蛋白、肝磷脂、转铁蛋白饱和度和脂质过氧化产物,为患者分层和治疗监测提供了潜在的工具。结论通过先进的螯合策略靶向铁调节失调和铁下垂有望成为COPD治疗的新途径。将机制见解与精确递送技术相结合,可以通过减轻铁驱动的氧化性肺损伤来提高治疗效果和改善临床结果。
期刊介绍:
The journal provides the reader with a thorough description of theoretical and applied aspects of trace elements in medicine and biology and is devoted to the advancement of scientific knowledge about trace elements and trace element species. Trace elements play essential roles in the maintenance of physiological processes. During the last decades there has been a great deal of scientific investigation about the function and binding of trace elements. The Journal of Trace Elements in Medicine and Biology focuses on the description and dissemination of scientific results concerning the role of trace elements with respect to their mode of action in health and disease and nutritional importance. Progress in the knowledge of the biological role of trace elements depends, however, on advances in trace elements chemistry. Thus the Journal of Trace Elements in Medicine and Biology will include only those papers that base their results on proven analytical methods.
Also, we only publish those articles in which the quality assurance regarding the execution of experiments and achievement of results is guaranteed.
