Abstract:

BACKGROUND: Various risk factors in atherosclerosis are closely related to the number and functions of endothelial progenitor cells (EPCs). Therefore, EPCs play an important role in the development of atherosclerosis, and increasing the number and functions of endothelial progenitor cells may be an important target for the treatment of atherosclerosis.
OBJECTIVE: To elaborate the effect of oxidized low-density lipoprotein on EPCs functions.
METHODS: PubMed and Chinese journal databases were searched by using “oxidized low-density lipoprotein, endothelial progenitor cells, atherosclerosis” as the search terms in English and Chinese, respectively. Finally, 42 articles were further analyzed.
RESULTS AND CONCLUSION: Oxidized low-density lipoprotein, an important lipoprotein that induces atherosclerosis, can impair vascular endothelial cells to induce endothelial dysfunction, and contributes to foam cell formation and plaque stability. Oxidized low-density lipoprotein can damage the functions of EPCs, such as proliferation, migration, adhesion, angiogenesis, which reduces the effect of EPCs on vascular repair. Therefore, how to improve the number and functions of EPCs in atherosclerotic patients is an important target for the treatment of early atherosclerosis.
