Additional Information

Official title To Study the Effect of Vytorin on Intracellular Lipid and Inflammation in Obese Subjects
Principal investigator Paresh Dandona, MD
Description Following the first demonstration by our group that macronutrient (glucose, cream and a high fat high carbohydrate meal) intake results in increased ROS generation and oxidative stress at the cellular and molecular level, the investigators have now shown in our preliminary data that cream intake induces comprehensive inflammation as reflected in increased intranuclear NFkB binding, decreased IkBα expression, increased expression of IL-1β, IL-12, TNFα and other pro-inflammatory mediators. While carrying out these experiments, the investigators asked whether cream intake was associated with an uptake of lipid by peripheral blood mononuclear cells (MNC). Indeed, there was a significant increase in intracellular lipid which was visualized as intracellular lipid droplets. The increase in intracellular lipid droplets was associated with an increase in intracellular superoxide generation; the expression of CD68, a marker for macrophages; and PECAM, the adhesion molecule which mediates trans- endothelial transfer of leucocytes. The investigators also found that the lipid fractions to increase were cholesterol ester, triglyceride and fatty acids. In view of the tantalizing observation that the lipid droplet laden MNC appeared to be monocytes, looked like foam cells and the fact that CD68 expression had increased, there is a possibility that foam cells may be formed in peripheral circulation by monocytes after a lipid rich meal. This simple model of foam cell formation also lends itself for the study of the effect of various lipid lowering drugs. Our investigation will be the first to study this novel paradigm. The investigators plan to study the effect of a cholesterol lowering agent, Vytorin (simvastatin and ezetimibe), on intracellular lipid in MNC, expression of CD68 and PECAM, ROS generation and inflammation in obese subjects. This investigation may provide an additional mechanism of action by which these drugs may reduce atherosclerosis.
