CFTR inhibitors triggered epidermal growth factor receptor phosphorylation that was required for VEGF-A synthesis. Cystic fibrosis airways at transplantation showed increased peribronchial vascularity and epithelial VEGF-A expression. CFTR dysfunction triggered epithelial synthesis of VEGF-A, which may contribute to vascular remodelling.
