Scientific data indicates that increasing HDL cholesterol may decrease the risk of heart disease, the leading cause of death for men and women in the United States. We propose to determine the mechanisms by which a new class of drugs, known as PPAR delta agonists, increase HDL-cholesterol in monkeys. Because of the high degree of similarity between the bodies of humans and monkeys, we feel confidant that these studies will provide insights for the development of therapies that could increase HDL and prevent the deaths of hundreds of thousands of people each year from heart disease.
