以铁死亡、铜死亡为中心的金属离子依赖的调控性细胞死亡通路在纤维化疾病中发挥关键作用。铁、铜离子的细胞摄取-储存-外排紊乱引起氧化还原失衡,继而激活经典及非经典TGF-β/Smad通路、驱动上皮-间质转化(EMT)与成纤维...展开更多
以铁死亡、铜死亡为中心的金属离子依赖的调控性细胞死亡通路在纤维化疾病中发挥关键作用。铁、铜离子的细胞摄取-储存-外排紊乱引起氧化还原失衡,继而激活经典及非经典TGF-β/Smad通路、驱动上皮-间质转化(EMT)与成纤维细胞-肌成纤维细胞转化(FMT)并促进损伤相关分子模式释放以放大炎症-纤维化环路,从而促进器官纤维化。线粒体三羧酸循环为铁、铜死亡共同交汇点。由此衍生的靶向干预策略(包括金属离子螯合剂、中药衍生物、小分子靶向药、纳米材料)通过重建金属离子稳态、阻断EMT/FMT及抑制氧化应激,显示出良好的抗纤维化潜力。收起

Metal ion-dependent regulated cell death pathways,centered on ferroptosis and cuproptosis,play key roles in fibrotic diseases.Disruptions in the cellular uptake,storage,and efflux of iron and copper ions lead to redox imbalance,which subsequently activates the canonical and non-canonical transforming growth factor-β/Smad pathways,drives epithelialmesenchymal transition(EMT)and fibroblast-myofibroblast transition(FMT),and promotes the release of damageassociated molecular patterns to amplify the inflammation-fibrosis loop,thereby promoting organ fibrosis.The mitochondrial tricarboxylic acid cycle serves as a common convergence point of ferroptosis and cuproptosis.Targeted intervention strategies derived from related pathways,including metal ion chelators,traditional Chinese medicine derivatives,small-molecule targeted drugs,and nanomaterials,show favorable anti-fibrotic potential by restoring metal ion homeostasis,blocking EMT/FMT and inhibiting oxidative stress.FEWER
