In DTA+/Scnn1b‐Tg mice, lung disease was more severe than in DTA−/Scnn1b‐Tg littermates, as indicated by an increased incidence of mucus plugging, mucous cells, airway inflammation, higher levels of cytokines/chemokines (KC, TNF‐α, MIP‐2, M‐CSF, IL‐5, and IL‐17), and worsened alveolar airspace enlargement. The gene discussed is IL5; the disease is lung disorder.
