Red blood cells participate in reverse cholesterol transport by mediating cholesterol efflux of high-density lipoprotein and apolipoprotein A-I from THP-1 macrophages

High-density lipoprotein (HDL) plays a main role in reverse cholesterol transport (RCT), one of the most important functions for preventing atherosclerosis. Recent reports have shown that red blood cells (RBCs) can be associated with RCT, an interaction facilitated by albumin. However, the RCT function of RBCs has not been thoroughly elucidated. In this study, the RCT function of RBCs was assessed using cholesterol efflux capacity (CEC) assays,...
