Molecular mechanisms of the regulatory action of high-density lipoproteins on the endothelial function

Abstract

Endothelial dysfunction underlies the pathogenesis of many diseases, primarily cardiovascular diseases. Epidemiological studies have shown an inverse dependence between the plasma level of high-density lipoproteins (HDL) and cardiovascular diseases. The results of experimental studies indicate that the antiatherogenic effect of HDL is associated not only with their participation in the reverse transport of excess cholesterol, but also with their regulatory effect on the functions of cells of various organs and tissues, including endothelial cells. The purpose of this review is to consider recent data on the participation of plasma receptors and related intracellular signaling pathways in the mechanism of protective effect of HDL on endothelial cell functions. Understanding the mechanisms of cell function regulation under the influence of HDL is an important step for the development of new ways of pharmacological correction of impaired endothelial functions and creation of effective endothelial protection drugs.
