On the other hand, C-C motif chemokine ligand 20 (CCL20), fibroblast growth factor 19 (FGF19), IL-5, leukemia inhibitory factor (LIF), tumor necrosis factor ligand superfamily member 9 (TNFRSF9), and urokinase-type plasminogen activator (uPA) were associated only with individuals with overweight/obesity (43), but these were not found to be associated with airway remodeling. This evidence concerns the gene LIF and Obesity.
