Subroto Chatterjee, director of the Johns Hopkins sphingolipid signaling and vascular biology laboratory, discusses his research on lipid proteins. The focus of Chatterjee’s laboratory is on lipids and lipoproteins, which are molecules that carry lipids and proteins. LDL (low-density lipoprotein) is bad cholesterol, that leads to heart disease. HDL (high-density lipoprotein) protects people from having this disease. Glycolipids are molecules that have other sugars and fat attached to them. The goal of Chatterjee’s research is to develop techniques to lower the levels of glycolipids, which could reduce the rate of heart disease.
