Mucosal polyps in the mucosa of TNFA-/-mice following NTHi challenge. A. Examples of polyps (arrows) in the ME mucosa of TNF KO mice at various intervals after NTHi inoculation. H&E staining. Magnification A-C = 40x, D = 80x. B. Percentage of ears in which polyps were found in serial sections. While polyps were common in TNFA-/- MEs, only one polyp was seen in WT animals. n = 6-10 for each group.
