In advanced atherosclerosis (AS), defective function-induced cell death leads to the formation of the characteristic necrotic core and vulnerable plaque. The forms and mechanisms of cell death in AS have recently been elucidated. Among them, ferroptosis, an iron-dependent form of necrosis that is characterized by oxidative damage to phospholipids, promotes AS by accelerating endothelial dysfunction in lipid peroxidation. Moreover, disordered intracellular iron causes damage to macrophages, vascular smooth muscle cells (VSMCs), vascular endothelial cells (VECs), and affects many risk factors or pathologic processes of AS such as disturbances in lipid peroxidation, oxidative stress, inflammation, and dyslipidemia. However, the mechanisms through which ferroptosis initiates the development and progression of AS have not been established. This review explains the possible correlations between AS and ferroptosis, and provides a reliable theoretical basis for future studies on its mechanism.
在动脉粥样硬化(AS)的晚期,功能缺陷诱导的细胞死亡导致特征性坏死核心和易损斑块的形成。最近已经阐明了 AS 中细胞死亡的形式和机制。其中,铁依赖性坏死形式的铁死亡,其特征是磷脂的氧化损伤,通过在脂质过氧化中加速内皮功能障碍来促进 AS。此外,细胞内铁的紊乱会损害巨噬细胞、血管平滑肌细胞(VSMCs)、血管内皮细胞(VECs),并影响 AS 的许多危险因素或病理过程,如脂质过氧化、氧化应激、炎症和血脂异常的紊乱。然而,铁死亡引发 AS 发展和进展的机制尚未建立。本综述解释了 AS 与铁死亡之间的可能相关性,并为其机制的未来研究提供了可靠的理论基础。
