Plasma cholesteryl ester transfer protein.
The plasma lipoproteins are continuously remodeled during their transit through the plasma compartment, owing to the action of lipid metabolizing enzymes and lipid transfer processes. These activities have a major effect on the composition, size, and concentration of the lipoproteins. Lipid transfer processes involving neutral lipids and phospholipids are mediated by specialized plasma proteins...
متن کاملCholesteryl ester transfer from phospholipid vesicles to human density lipoproteins.
The exchange of cholesteryl esters between different lipoproteins was reported to bae mediated by a protein present in human plasma. In this study wer have examined the movement of cholesteryl ester from unilamellar phospholipid vesicles to high density lipoprotein (HDL). Experimental conditions were establisehd so that vesicles containing egg yolk lecithin and cholesteryl oleatea (molar ratio ...
متن کاملTransfer of cholesteryl ester into high density lipoprotein by cholesteryl ester transfer protein: effect of HDL lipid and apoprotein content.
Recombinant high density lipoprotein (rHDL) particles were prepared by cosonication of purified lipids and human apoproteins and incubated with partly purified cholesteryl ester transfer protein (CETP) and low density lipoprotein (LDL) containing [3H]cholesteryl ester. Increasing the triglyceride content relative to cholesteryl ester in rHDL significantly decreased the ability of the particles ...
متن کاملLipoprotein lipase enhances the cholesteryl ester transfer protein-mediated transfer of cholesteryl esters from high density lipoproteins to very low density lipoproteins.
These studies were undertaken to examine the effects of lipoprotein lipase (LPL) and cholesteryl ester transfer protein (CETP) on the transfer of cholesteryl esters from high density lipoproteins (HDL) to very low density lipoproteins (VLDL). Human or rat VLDL was incubated with human HDL in the presence of either partially purified CETP, bovine milk LPL or CETP plus LPL. CETP stimulated both i...
متن کاملAccelerated Cholesteryl Ester Transfer
To discern the mechanism(s) that underlie abnormal cholesteryl ester transfer (CET) in patients with hypercholesterolemia, we have studied this dysfunctional step in reverse cholesterol transport in 13 subjects with genetically heterogeneous forms of hypercholesterolemia (HC). In all HC patients, the mass of CE transferred in whole plasma from HDL to VLDL and LDL increased rapidly initially and...
