Oxidized Low-Density Lipoprotein Augments and 3-Hydroxy-3-Methylglutaryl Coenzyme A Reductase Inhibitors Limit CD40 and CD40L Expression in Human Vascular Cells

Abstract

OxLDL may promote expression of CD40 and CD40L in human atheroma. Statins may limit the expression of the CD40 receptor/ligand dyad in two ways, directly as well as through diminished lipoprotein levels. Thus, reduced CD40 signaling may account for some of the statins' antiinflammatory action.
