Fluticasone reduces IL-6 and IL-8 production of cystic fibrosis bronchial epithelial cellsviaIKK-β kinase pathway

Abstract

Inhaled fluticasone propionate (FP) is widely used to reduce pulmonary inflammation in chronic obstructive pulmonary disease, but the potential effects of FP on airway epithelial cells from patients with cystic fibrosis (CF) are unknown. In CF disease, a nonregulated inflammatory lung response occurs through exaggerated nuclear factor (NF)-κB activation and elevated pro-inflammatory cytokines production by airway epithelial cells.
