正常动脉内膜及外膜有少量散在单核巨噬细胞,除部分来自滋养血管外膜,多数系由循环单核细胞经内皮细胞间隙进入衍生。单核巨噬细胞作为一个多功能细胞通过吞噬及其分泌产物等对维持动脉壁正常生理功具有重要作用,在许多血管或动脉疾病发生过程中,血管壁巨噬细胞浸润增生并构成病变的重要细胞成分。动脉粥样硬化斑块特征性病理形态学表 Normal arterial intima and adventitia scattered a small amount of mononuclear macrophages, in addition to some from the nourishment of vascular adventitia, the majority of circulating monocytes by the endothelial cell gap into the derived. As a multifunctional cell, mononuclear macrophages play an important role in maintaining normal physiological functions of the arterial wall by phagocytosis and its secretion products. In many vascular or arterial diseases, vascular macrophages infiltrate and proliferate and constitute an important lesion Cell components. Atherosclerotic plaques characteristic histopathology
