Brief description It is well known that high levels of cholesterol in blood cause coronary heart disease. It is also known that not all of the cholesterol in blood is bad. Whereas the cholesterol carried in particles called low density lipoproteins (LDLs) causes heart disease, other cholesterol carriers in blood known as high density lipoproteins (HDLs) actually protect against the development of heart disease. However, HDLs include several different populations of particles, only some of which are protective. One determinant of the ability of HDLs to protect against coronary heart disease is their protein composition. This project investigates how the protein composition of HDL populations influences their structure, function and metabolism. It is also concerned with understanding what regulates the relative concentrations of the different HDL populations. The studies of HDL structure, function and metabolism will allow us to understand why the different HDL populations differ in their abilities to protect against heart disease. The regulation studies will tell us how to go about designing therapies to increase the levels of those HDL populations that do protect.
