The levels of basic fibroblast growth factor (bFGF) in the bronchoalveolar lavage fluid (BALF) of patients with asthma have been demonstrated to be significantly higher compared with non-asthmatic patients, and were further increased following allergen exposure, indicating that bFGF is associated with airway remodeling in asthma (10). This evidence concerns the gene FGF2 and asthma.
