Macrophage reverse cholesterol transport in mice expressing ApoA-I Milano.
OBJECTIVE To compare the abilities of human wild-type apoA-I (WT apoA-I) and human apoA-I(Milano) (apoA-I(M)) to promote macrophage reverse cholesterol transport (RCT) in apoA-I-null mice infected with adeno-associated virus (AAV) expressing either WT apoA-I or apoA-I(M). METHODS AND RESULTS WT apoA-I- or apoA-I(M)-expressing mice were intraperitoneally injected with [H(3)]cholesterol-labeled...
متن کاملMacrophage reverse cholesterol transport: key to the regression of atherosclerosis?
The concept of “reverse cholesterol transport” (RCT) was first introduced in 1968 by Glomset1 to describe the process by which extrahepatic (peripheral) cholesterol is returned to the liver for excretion in the bile and ultimately the feces. The physiological need for this process is clear, as nonhepatic cells acquire cholesterol through uptake of lipoproteins and de novo synthesis and yet (wit...
متن کاملLymphatic vasculature mediates macrophage reverse cholesterol transport in mice.
Reverse cholesterol transport (RCT) refers to the mobilization of cholesterol on HDL particles (HDL-C) from extravascular tissues to plasma, ultimately for fecal excretion. Little is known about how HDL-C leaves peripheral tissues to reach plasma. We first used 2 models of disrupted lymphatic drainage from skin--1 surgical and the other genetic--to quantitatively track RCT following injection o...
متن کاملThe Role of Macrophage Lipophagy in Reverse Cholesterol Transport
Macrophage cholesterol efflux is a central step in reverse cholesterol transport, which helps to maintain cholesterol homeostasis and to reduce atherosclerosis. Lipophagy has recently been identified as a new step in cholesterol ester hydrolysis that regulates cholesterol efflux, since it mobilizes cholesterol from lipid droplets of macrophages via autophagy and lysosomes. In this review, we br...
متن کاملFish oil promotes macrophage reverse cholesterol transport in mice.
OBJECTIVE Fish oil (FO), and specifically omega 3 fatty acids, has favorable effects on cardiovascular outcomes. The aim of this study was to investigate the effects of FO on the process of macrophage reverse cholesterol transport (RCT) in an in vivo mouse model. METHODS AND RESULTS C57BL/6J mice were fed a FO diet, whereas control mice were fed diets containing alternative sources of fats, s...
