    Abstract:
    HMG-CoA reductase inhibitors (statins) are believed to reduce coronary heart disease by mechanisms in addition to their well-known cholesterol-lowering effect. We studied the effect of these drugs on monocyte cell adhesion to endothelium. Pretreatment of monocytic cells (U937, THP-1, human CD14(+) monocytes) with 0.01-10 microM concentrations of atorvastatin, cerivastatin, or simvastatin significantly reduced cell adhesion to endothelium. In contrast, pretreatment of endothelium with statins did not affect adhesion of monocytes. Adhesion of monocytes to vascular cell adhesion molecule-1-coated dishes was reduced by these drugs. Cerivastatin also reduced PMA induction of NF-kappaB. Since monocyte adhesion to endothelium is an early event in atherogenesis, treatment with statins in prevention of coronary heart disease may have additional salutary effects to lowering of plasma LDL cholesterol. Our results indicate that the reduction of monocyte adhesion by HMG-CoA reductase inhibitors may be considered as a class effect.
