Ferroptosis is a type of cell death that differs from general forms of cell death such as apoptosis. Iron accumulation and lipid peroxidation are distinct biochemical features of ferroptosis. Accumulation of iron ions in ferrodead cells can increase the probability of the Fenton reaction and produce more reactive oxygen species (ROS). Further, iron ions are cofactors for some intracellular oxidases. ROS, which are normally produced in the mitochondria, attack the phospholipid bilayer of the cell and produce lipid peroxides that ultimately kill the cell. Since the discovery of ferroptosis, its mechanism and relationship with diseases, such as nervous system diseases, tumors, and sepsis has been studied. Controlling disease development by regulating ferroptosis has thus become a popular topic of current research. This article summarizes the recent research progress on the mechanism of ferroptosis and its relationship with diseases. Overall, this study can provide a valuable reference for future ferroptosis studies.
铁死亡是一种不同于凋亡等一般形式细胞死亡的细胞死亡类型。铁积累和脂质过氧化是铁死亡独特的生化特征。铁死亡细胞中铁离子的积累会增加芬顿反应的可能性,并产生更多的活性氧(ROS)。此外,铁离子是一些细胞内氧化酶的辅助因子。通常在线粒体中产生的ROS攻击细胞的磷脂双层并产生脂质过氧化物,最终杀死细胞。自铁死亡被发现以来,其机制以及与神经系统疾病、肿瘤和脓毒症等疾病的关系已得到研究。通过调节铁死亡来控制疾病发展因此成为当前研究的热门话题。本文总结了铁死亡机制及其与疾病关系的最新研究进展。总体而言,本研究可为未来铁死亡研究提供有价值的参考。
