Longitudinal dynamics of inflammatory module expression and differential patterns of sequential module activation. 4a. Early inflammatory module activation includes SMAD3 to initiate inflammation and exacerbation. 4b. A second phase of inflammatory module activation includes genes associated with eosinophil activation and mucus hypersecretion, MUC5AC. The second phase leads to progression and persistent inflammation and airflow obstruction [47]. Reprinted with permission.
