| In vitro study | In human lung fibroblasts, Fluticasone propionate(1 pM) inhibited the constitutive and TGF-β-induced expression of α-SMA. Fluticasone propionate blocks nuclear translocation of the pro-inflammatory transcription factor NF-κB induced by TNF-α in human lung fibroblasts. Fluticasone propionate inhibits IL-13 (tyrosine kinase 2,STAT1,STAT3,STAT6, mitogen-activated protein kinase)-induced activation of the Janus kinase/STAT pathway in the early stages of lung fibroblast differentiation. In mildly or fully differentiated myofibroblast cultures, Fluticasone propionate still exhibited potential anti-inflammatory activity, although it only inhibited phosphorylation of tyrosine kinase 2. In early and mildly differentiated myofibroblasts, Fluticasone propionate inhibited constitutive and TGF-β-induced expression of α-smooth muscle actin, which is a major marker of myofibroblast differentiation. Fluticasone propionate exhibited an additional powerful anti-inflammatory effect, reducing the nuclear translocation of myofibroblast NF-κB independent of its degree of differentiation. Fluticasone propionate inhibited allergen-induced T cell proliferation, expression of IL-3,IL-5, and GM-CSF mRNA, and secretion of the corresponding proteins in a concentration-dependent manner. Fluticasone propionate significantly inhibited allergen-induced T-cell production of asthma-related cytokines. |
| In vivo study | In horses, Fluticasone propionate administration after induction of severe eye deterioration resulted in complete resolution of clinical symptoms, normalization of pulmonary function tests and a significant decrease in bronchoalveolar neutrophil lavage (BAL). |
