Abstract
Background— Statins exert anti-inflammatory effects independently of cholesterol-lowering properties. Cytomegalovirus (CMV) infection appears to be implicated in the pathophysiology of atherosclerosis by inducing inflammatory modifications in endothelial cells, especially in immunosuppressed patients. We investigated whether the activity of statins can inhibit replication of CMV in human endothelial cells. Methods and Results— Human umbilical vein endothelial cells (HUVECs) were infected with CMV and coincubated with fluvastatin at 0.1 and 0.2 μmol/L. Fluvastatin inhibited (PP3 pfu/mL, PConclusions— HMG-CoA inhibition by fluvastatin restrains CMV replication in HUVECs by inhibiting viral antigen expression, DNA synthesis, and viral particle production, conceivably by involving a reduction of nuclear factor-κB binding activity.
