Sepsis is a complicated clinical disease caused by a defective host response to infection, leading to elevated morbidity and fatality globally. Sepsis patients have a significant risk of life-threatening organ damage, including hearts, brains, lungs, kidneys, and livers. Nevertheless, the molecular pathways driving organ injury in sepsis are not well known. Ferroptosis, a non-apoptotic cell death, occurs due to iron metabolism disturbance and lipid peroxide buildup. Multiple studies indicate that ferroptosis has a significant role in decreasing inflammation and lipid peroxidation during sepsis. Ferroptosis inhibitors and medications, aimed at the most studied ferroptosis process, including Xc-system, Nrf2/GPX4 axis, and NCOA4-FTH1-mediated ferritinophagy, alleviating sepsis effectively. However, few clinical trials demonstrated ferroptosis-targeted drugs's effectiveness in sepsis. Our study examines ferroptosis-targeted medicinal agents and their potential benefits for treating sepsis-associated organ impairment. This review indicates that ferroptosis suppression by pharmaceutical means may be a useful therapy for sepsis-associated organ injury.
脓毒症是一种由宿主对感染的反应缺陷引起的复杂临床疾病,在全球范围内导致发病率和死亡率升高。脓毒症患者有发生危及生命的器官损伤的重大风险,包括心脏、大脑、肺、肾脏和肝脏。然而,驱动脓毒症器官损伤的分子途径尚不清楚。铁死亡是一种非凋亡性细胞死亡,由于铁代谢紊乱和脂质过氧化物积累而发生。多项研究表明,铁死亡在减轻脓毒症期间的炎症和脂质过氧化方面具有重要作用。针对研究最多的铁死亡过程(包括Xc-系统、Nrf2/GPX4轴和NCOA4-FTH1介导的铁自噬)的铁死亡抑制剂和药物可有效减轻脓毒症。然而,很少有临床试验证明靶向铁死亡的药物在脓毒症中的有效性。我们的研究考察了靶向铁死亡的药物制剂及其对治疗脓毒症相关器官损伤的潜在益处。这篇综述表明,通过药物手段抑制铁死亡可能是治疗脓毒症相关器官损伤的一种有效疗法。
