Cholesteryl ester transfer proteins, reverse cholesterol transport, and atherosclerosis.
Plasma cholesteryl ester transfer protein plays a central role in lipoprotein metabolism by exchanging cholesteryl esters with triglycerides. Human genetic deficiency is associated with increased HDL-cholesterol levels, whereas cholesteryl ester transfer protein overexpression in transgenic mice results in decreased HDL-cholesterol. Thus, it has been proposed that cholesteryl ester transfer protein deficiency is an antiatherogenic state. However, recent observations in human cholesteryl ester transfer protein deficiency and cholesteryl ester transfer protein transgenic mice also suggest antiatherogenic effects of the expression of this protein, probably reflecting its role in reverse cholesterol transport.
