Abstract:
OBJECTIVE: To investigate the effect of anti-psoriatic drug fumaric acid esters (FAE) on the differentiation of dendritic cells (DC). METHODS: Dendritic cells were obtained by differentiating human monocytes in vitro. Flow cytometry was used to analyse the effect of FAE on cell surface expression of CD1a, CD14, CD40, CD80, CD86 and HLA-DR by monocyte-derived dendritic cells (MoDC). Mixed lymphocyte reaction (MLR) was made to demonstrate the influence of FAE on T cell stimulatory activity of MoDC. RESULTS: Dimethylfumarate and methylhydrogenfumarate-calcium-salt (0.01 approximate, equals 100 mg/L) inhibited MoDC differentiation as well as reducing the capacity of MoDC to stimulate lymphocytic proliferation in MLR. CONCLUSION: The mode of action of FAE in pso riasis may be mediated by inhibition of DC differentiation.
