Different locations of cholesteryl ester transfer protein and phospholipid transfer protein activities in plasma.
Activities of cholesteryl ester transfer protein (CETP) and phospholipid transfer protein (PLTP) were measured in plasma of four vertebrate species: man, rabbit, pig, and rat. The activities were measured in the absence and presence of antibodies raised against purified human CETP. PLTP activities were present in all four species with highest values in pig (11.7 +/- 1.2 U/ml) and human plasma (...
متن کاملCholesteryl ester transfer protein and phospholipid transfer protein have nonoverlapping functions in vivo.
Plasma phospholipid transfer protein (PLTP) and cholesteryl ester transfer protein (CETP) are homologous molecules that mediate neutral lipid and phospholipid exchange between plasma lipoproteins. Biochemical experiments suggest that only CETP can transfer neutral lipids but that there could be overlap in the ability of PLTP and CETP to transfer or exchange phospholipids. Recently developed PLT...
متن کاملCholesteryl ester transfer between high density lipoprotein and phospholipid bilayers.
High density lipoprotein-associated cholesteryl esters (HDL CE) are taken up by many cells without parallel uptake of HDL apoproteins, a pathway we have termed "selective uptake." The first step in this pathway, the reversible incorporation of HDL CE into the plasma membrane, is the subject of the present study. To examine the role of membrane proteins, the rate of HDL CE incorporation into iso...
متن کاملPlasma phospholipid transfer protein, cholesteryl ester transfer protein and lecithin:cholesterol acyltransferase in end-stage renal disease (ESRD).
BACKGROUND Chronic kidney disease (CKD) results in accelerated atherosclerosis that is primarily caused by inflammation, oxidative stress and impaired triglyceride and HDL metabolisms. Several plasma proteins including phospholipid transfer protein (PTLP), cholesteryl ester transfer protein (CETP) and lecithin:cholesterol acyltransferase (LCAT) affect HDL metabolism. PLTP transfers phospholipid...
متن کاملPlasma 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...
