CETP (Cholesteryl Ester Transfer Protein)

CETP, or Cholesteryl Ester Transfer Protein, is a protein in the blood that helps transfer cholesterol between different types of lipoproteins, mainly from HDL ("good" cholesterol) to LDL ("bad" cholesterol). This process influences cholesterol levels and can affect heart health. High CETP activity may reduce HDL cholesterol, potentially increasing the risk of cardiovascular disease, while lower activity can raise HDL levels. Scientists study CETP to develop medications that modify its function, with the goal of improving cholesterol balance and reducing heart disease risk.
