Abstract

English

For years Fumaric acid esters (FAE) have been successfully used in the systemic treatment of severe psoriasis. However, their pleiotropic mode of action is not yet fully understood. To further elucidate the mode of action of FAE, the effect of dimethylfumarate (DMF) and monomethylfumarate (MMF) on human endothelial cells in vitro was investigated. As Psoriasis is associated with inflammatory lymphocytic infiltrates, it was focused on adhesion molecule expression and the interaction between endothelial cells and human peripheral blood mononuclear cells (PBMC) under conditions of shear flow. Dimethylfumarate concentration-dependently reduced the TNFα-induced expression of E-selectin (CD62E), ICAM-1 (CD54) and VCAM-1 (CD106) on human umbilical vein endothelial cells (HUVEC), both on mRNA and protein level. All three proteins are essential for the initial steps of lymphocyte recruitment to inflamed tissues. Treatment with dimethylfumarate concentrations ranging between 25
