Mediating reverse cholesterol transport (RCT) is the most classic function of HDL. HDL and HDL-C participate in the entire process of RCT, including cholesterol removal from cells, cholesterol transport in circulation, and cholesterol excretion. As cholesterol is a component of lipid rafts and lipid droplets in cells, HDL and RCT can influence cell activity. HDL has also been shown to be related to the metabolism of some other biological lipids, such as S1P and ox-PL. Here we will introduce in detail the molecular mechanism of HDL participation in RCT and its significance. © 2022. Springer Nature Singapore Pte Ltd.
