Cholesterol Ester Transfer Protein (CETP), also known as the plasma lipid transfer protein, is a plasma protein that promotes the exchange of cholesterol esters and triglycerides between high density proteins (HDL) and apolipoprotein B100- containing lipoprotein particles. The concentration and activity of plasma CETP correlate with the concentration of HDL-C and is also used to predict the risk of atherosclerosis and cardiovascular events. Creative BioMart Biomarker is capable to provide our customers with superior CETP detection service, various detection methods ensuring high sensitivity for detecting biomarkers in different samples with different concentrations.
CETP is primarily bound with high density lipoprotein (HDL) in the circulation. CETP can equimolar transfer neutral lipids, including cholesterol ester (CE) and triglycerides (TG), between plasma HDL and apolipoprotein B100-containing lipoprotein particles. The net effect of CETP is to transfer CE from HDL to very low density lipoprotein (VLDL) and low density lipoprotein (LDL), shifting TG in the opposite direction. In humans and monkeys, CETP is mainly expressed in the liver, small intestine, adipose tissue and spleen. In human plasma, the concentration of CETP is approximately 2 μg/ml, and is higher in subjects with dyslipidemia, which is mainly associated with HDL. Plasma cholesterol ester transfer activity depends on CETP concentration and the ability of CETP to interact with lipoproteins. Studies have shown that when CETP levels are inhibited, the level of HDL-C is significantly increased, thereby reducing the risk of atherosclerosis. The opposite study found that when HDL-C levels were higher, CETP levels were lower and cardiovascular risk was lower. At the same time, when CETP activity is low, there are fewer cardiovascular events. Therefore, by measuring the concentration and activity of plasma CETP, the level of HDL-C can be predicted to predict the probability of disease occurrence.
