Cholesterol accumulation in arterial macrophages and inflammation of the artery wall both contribute to the development of cardiovascular disease (CVD). HDL appears to protect against CVD by several mechanisms that remove cholesterol from arterial cells and suppress inflammation. A major cardioprotective factor associated with HDL metabolism is ATP-binding cassette transporter A1 (ABCA1), a cell membrane protein that exports cholesterol and phospholipids from cells to lipid-depleted HDL apolipoproteins, such as apoA1. My research focuses on studies of biochemical mechanisms and signaling pathways by which ABCA1 functions as cholesterol exporter and anti-inflammation molecule. Another focus of my research is the studies of the effects and mechanisms of diabetes and diabetes associated factors on ABCA1 and ABCG1.
