Inhibition of Cytokine Production and Adhesion Molecule Expression by Ibuprofen is Without Effect on Transendothelial Migration of Monocytes

Abstract
The present study focusses on the effects of ibuprofen and its enantiomers on cytokine production by peripheral blood monocytes and endothelial cells as well as on the potential modulation of ADM-expression by human umbilical vein endothelial cells and the concomitant effects on monocyte transendothelial migration as measured by a cell migration assay system. This consists of an endothelial cell monolayer on a solid collagen substrate, i.e. an artificial vessel wall construct. We observed a significant inhibition by 100 μg/ml ibuprofen of VCAM-1 expression by endothelial cells while ELAM-1 and ICAM-1 expression was not influenced. However, we could not see any concomitant inhibitory effects on the spontaneous migration of monocytes after preincubating the endothelial cell monolayer with ibuprofen up to concentrations of 100 μg/ml and activating with suboptimal and optimal concentrations of TNF-α. Our monocyte transendothelial migration system reflects very sensitively endothelial cell-activation even by very low TNF-α concentrations. (S)- and (R)-ibuprofen were equal in their inhibitory/activating effects on cytokine production, with the exception of stronger IL-8 induction in endothelial cells by (R)-ibuprofen as compared to its chiral analogue.
