摘要
铁元素是多种蛋白及酶的辅助元素。动脉硬化(atherosclerosis,AS)是一种全身性慢性炎症性血管疾病。铁可以导致巨噬细胞中ROS产生增多,且会促进脂质过氧化,最终促进动脉粥样硬化的进展并降低斑块的稳定性。尽管铁在动脉粥样硬化中的作用已经比较清楚,但关于斑块处铁代谢紊乱的机制仍未清楚,本文对铁代谢与动脉硬化的相关性进行综述,旨在了解并阐述炎症、肥胖等动脉硬化的危险因素和铁代谢之间的关系,从而对动脉硬化的诊断及治疗有一定的启发。
Iron is an essential mineral in many proteins andenzymes in human physiology and is involved in various inflammation disease like atherosclerosis. Atherosclerosis is a chronic systemic inflammation disease. In atherosclerosis, iron catalyzes the creation of reactive oxygen free radicals that contribute to lipid modification, which is essential to atheroma formation. Inflammation further fuels iron-related pathologic processes associated with plaque progression. Although iron is very important in atherosclerosis development, the detailed mechanism of iron obstruction in atherosclerosis plaque is unclear. This review summarizes the role of iron in atherosclerosis with considerable implications for novel diagnostic and therapeutic approaches.
