The plasma lipid transfer proteins mediate the transfer and exchange of phospholipids and neutral lipids between the plasma lipoproteins. The cholesteryl ester transfer protein (CETP) and the phospholipid transfer protein (PLTP) are members of the lipid transfer/lipopolysaccharide binding gene family. The CETP contains binding sites for cholesteryl ester and triglycerides and probably acts by a...

To determine whether nonhuman primates demonstrate the same alterations in transport of cholesteryl ester (CE) in plasma observed in diabetic humans, cholesteryl ester transfer (CET) was measured in cynomolgus monkeys with chronic spontaneous diabetes mellitus (glycated hemoglobin: diabetics 10.7 +/- 4.1%; controls 3.8 +/- 0.8%, P < 0.005). Among the plasma lipids, only triglycerides were signi...

We studied the ability of lipid-transfer factors in plasma to promote transfer, to endogenous lipoproteins, of [3H]cholesteryl ester from high-density lipoprotein (HDL) covalently bound to Sepharose 4B beads. After incubation for 2 h at 37 degrees C, 12 to 14% of the [3H]cholesteryl ester had been transferred to the lipoproteins of the plasma, in the proportions 57% to HDL and 43% to low- and v...

Cholesteryl ethers are nonhydrolyzable tracers of cholesteryl esters. We report here that the ethers are not legitimate tracers of esters in systems involving plasma cholesteryl ester transfer activity. On intravenous injection of doubly labeled high density lipoproteins into rabbits, cholesteryl ester tracer was more rapidly transferred to other lipoprotein fractions than was cholesteryl ether...

abstract      background and objective: diabetes mellitus is the most common risk factor for coronary artery disease (cad). cholesteryl ester transfer protein (cetp) taqib polymorphism is associated with changes in lipid profile and may be a risk factor for cad in patients with diabetes. this study aimed to evaluate the association of cetp taqib polymorphism with cad in patients with type 2 dia...

We have isolated from human plasma a unique subclass of the high density lipoproteins (HDL) which contains a potent lipid transfer inhibitor protein (LTIP) that inhibited cholesteryl ester, triglyceride, and phospholipid transfer mediated by the lipid transfer protein, LTP-I, and phospholipid transfer mediated by the phospholipid transfer protein, LTP-II. This HDL subclass not only inhibited ch...

Cholesteryl ester transfer to low density lipoproteins (LDL) was achieved either by incubation of a cholesteryl ester-rich lipid microemulsion with whole plasma or by incubation of the cholesteryl ester-rich microemulsion with lipoprotein-free plasma and LDL. Sequential ultracentrifugal isolation gave LDL that contained between 5 and 37% of the cholesteryl ester derived from the artificial chol...
