N2 - Lung fibroblasts play a key role in the pathogenesis of airway inflammation and remodeling through the release of mediators and the expression of surface molecules connected with cell-cell and cell-extracellular matrix interaction. The aim of the study was to evaluate the inhibitory effect of two corticosteroids, mometasone furoate (MOM) and dexamethasone (DEX), respectively, on a variety of fibroblast functions: DNA synthesis and proliferation, expression of adhesion molecules [intercellular adhesion molecule-1 (ICAM-1, CD54) and hyaluronic cellular adhesion molecule (HCAM, CD44)] and release of chemokines/cytokines [monocyte chemoattractant protein (MCP)-1, eotaxin, interleukin (IL)-6 and transforming growth factor (TGF)-β]. Cells from a human foetal lung fibroblast cell line (GM 06114) were stimulated with basic fibroblast growth factor (bFGF) or tumour necrosis factor (TNF)-α in the presence of different concentrations (0.01-100.0nM) of MOM or DEX. A significant increase in fibroblast DNA synthesis and proliferation was observed when the cells were stimulated with bFGF (p0.05, each comparison). The addition of MOM or DEX at the beginning of the cell cultures induced a significant downregulation in fibroblast DNA synthesis and proliferation, ICAM-1 and HCAM expression and chemokine/cytokine release (p0.05, each comparisons). These results extend the profile of the anti-inflammatory activity of mometasone furoate to lung fibroblast functions involved in airway inflammation and remodeling.
