Investigating the Relationship between FGF2 Gene Expression and Airway Remodeling in Severe Asthma.

Severe asthma causes chronic airway inflammation and structural changes in the bronchial wall. Fibroblast growth factor 2 (FGF2) plays an inflammatory role in specific pathways in airway remodeling in asthma. Assessing the relationship between sputum pattern, bronchial thickness by high-resolution computed tomography (HRCT) scan, and FGF2 expression level can evaluate the role of FGF2 in asthma remodeling.
