Participation of ABC-transporters in lipid metabolism and pathogenesis of atherosclerosis

Abstract

Atherosclerosis is one of the key causes of morbidity and mortality worldwide. It is known that a leading role in the development and progression of atherosclerosis is played by a violation of lipid metabolism. ABC transporters provide lipid cell homeostasis, performing a number of transport functions - moving lipids inside the cell, in the plasma membrane, and also removing lipids from the cell. In a large group of ABC transporters, about 20 take part in lipid homeostasis, playing, among other things, an important role in the pathogenesis of atherosclerosis. It was shown that cholesterol is not only a substrate for a number of ABC transporters, but also able to modulate their activity. Regulation of activity is carried out due to specific lipid-protein interactions.
