About this study
Official title: A Pilot Study to Evaluate the Use of 3H Particulate Cholesterol as a Method to Study Reverse Cholesterol Transport in Humans
The purpose of this study is to investigate the use of radiolabeled particulate cholesterol administered intravenously in association with albumin, as a method to study reverse cholesterol transport (RCT) in humans by analyzing changes in the tracer activity in total plasma, lipoproteins and feces.
Read the detailed description
The study will use 3H-cholesterol bound to albumin (particulate cholesterol) to assess the ability of HDL to transport cholesterol to the liver to be eliminated. This process is called Reverse Cholesterol transport and is one of the main mechanisms by which HDL protect against atherosclerotic cardiovascular disease. The availability of a method to assess RCT is important for the development of new drugs which affect RCT and may result in useful treatments for atherosclerosis.
This study will evaluate the use of radiolabeled particulate cholesterol administered intravenously in association with albumin, as a method to study reverse cholesterol transport (RCT) in humans by analyzing changes in the tracer activity in total plasma and lipoproteins. The study population is healthy volunteers.
