Cytology of nasal lavage (NAL) fluid and histology of nasal airway of WT (n = 10), mev (n = 7), mev x IL-4 KO (n = 7), and mev x IL-13 KO (n = 10) mice. (A) Total and differential cell counts were done with NAL samples from each group of mice (*P < 0.05, **P<0.01, and ***P<0.001). (B) Representative hematoxylin and eosin-stained (H&E) nasal sections from each group.
