Cholesterol efflux mediated by apolipoproteins is an active cellular process distinct from efflux mediated by passive diffusion.

It is becoming increasingly accepted that removal of cellular cholesterol occurs by at least two pathways, one involving the well-described aqueous diffusion mechanism and another promoted by lipid-free apolipoproteins. We compared the contribution of apolipoprotein-dependent and -independent pathways, taking into consideration the influence of cellular metabolism, on cholesterol efflux promote...

Cholesterol-sphingomyelin interaction in membrane and apolipoprotein-mediated cellular cholesterol efflux.

Helical apolipoproteins interact with cellular surface and generate high density lipoprotein (HDL) by removing phospholipid and cholesterol from cells. We have reported that the HDL is generated by this reaction with the fetal rat astrocytes and meningeal fibroblasts but cholesterol is poorly available to this reaction with the astrocytes (Ito et al. 1999. J. Neurochem. 72: 2362;-2369). Partial...

Influence of caveolin-1 on cellular cholesterol efflux mediated by high-density lipoproteins.

Caveolin-1 is a principal structural component of caveolae membranes. These membrane microdomains participate in the regulation of signaling, transcytosis, and cholesterol homeostasis at the plasma membrane. In the present study, we determined the effect of caveolin-1 expression on cellular cholesterol efflux mediated by high-density lipoprotein (HDL). We evaluated this effect in parental NIH/3...

A Possible Mechanism of Cellular Cholesterol Efflux*

After in vitro incubation with radiolabeled amino acids, extracts of various chicken tissues were reacted with antiserum against apolipoprotein AI (apo-AI) of plasma high density lipoprotein. Radiolabeled apo-AI was found in liver and intestine as well as in the kidney and a variety of peripheral tissues including aorta, peripheral arteries, veins, and skeletal muscle. The immunoreactive apo-AI...

Sphingomyelin-dependence of cholesterol efflux mediated by ABCG1.

ABCG1, one of the half-type ATP binding cassette (ABC) proteins, mediates the efflux of cholesterol to HDL and functions in the reverse cholesterol transport from peripheral cells to the liver. We have shown that ABCG1 mediates the efflux of not only cholesterol but also sphingomyelin (SM) and phosphatidylcholine. Because SM preferentially associates with cholesterol, we examined whether it pla...
