摘要
巨噬细胞是动脉粥样硬化发展过程中重要的免疫细胞之一,其表型及功能对于动脉粥样硬化发生发展具有重要决定作用,其中M1型巨噬细胞通过破坏其线粒体功能,促进糖酵解代谢及活性氧释放,干扰巨噬细胞脂质代谢平衡,维持和扩大炎症反应,降低巨噬细胞清除吞噬坏死细胞能力,加速坏死核心形成和不稳定斑块破裂发生。而M2型巨噬细胞则具有维持线粒体正常呼吸功能,促进氧化磷酸化代谢,增强胞内脂质流出,减轻炎症反应,修复受损组织并清理坏死细胞,维持斑块稳定性等方式抑制动脉粥样硬化进展。目前临床用于防治动脉粥样硬化的药物也表现出调控巨噬细胞极化的潜力。因此进一步探索并总结调控巨噬细胞极化在动脉粥样硬化病理过程中的分子机制及有效靶点是深入研究防治动脉粥样硬化有效措施的潜在方向。
Macrophages are one of the important immune cells in the development of atherosclerosis,and their phenotype and function play an important role in the occurrence and development of atherosclerosis.M1-type macrophages,by destroying their mitochondrial function,promote glycolysis and the release of reactive oxygen species,interfere with the balance of lipid metabolism of macrophages,maintain and expand the inflammatory response,and reduce the ability of macrophages to eliminate phagocytic necrotic cells.Accelerate the formation of necrotic cores and the occurrence of unstable plaque rupture.M2 type macrophages can maintain the normal respiratory function of mitochondria,promote oxidative phosphorylation metabolism,enhance intracellular lipid outflow,reduce inflammatory reaction,repair damaged tissues,clean necrotic cells,maintain plaque stability,and inhibit the progression of atherosclerosis.At present,the drugs used to prevent and treat atherosclerosis also show the potential to regulate the polarization of macrophages.Therefore,to further explore and summarize the molecular mechanism and effective target of regulating macrophage polarization in the pathological process of atherosclerosis is the potential direction of in-depth research on effective measures to prevent and treat atherosclerosis.
