2. Fig 1
Typical patterns of immunoreactivity for EP1 (A, B), EP2 (C, D), EP3 (E, F) and EP4 (G, H) receptors in nasal mucosal sections from a normal control (A, C, E, G, respectively) and a patient with aspirin-sensitive polypoid rhinosinusitis (B, D, F, and H, respectively). Using the avidin-biotin complex method, positive cells are stained brown.

Percentages of tubulin-β+ epithelial cells, Muc-5AC+ goblet cells, and CD90+ fibroblasts expressing immunoreactivity for EP1, EP2, EP3, and EP4 receptors in nasal mucosal sections from aspirin-sensitive (n = 12) and nonaspirin-sensitive polypoid rhinosinusitis (n = 10) and normal controls (n = 9). Mann-Whitney U test.

Percentages of inflammatory leukocytes (CD68+ macrophages, elastase+ neutrophils, tryptase+ mast cells, MBP+ eosinophils, and CD3+ T cells) expressing immunoreactivity for EP1 (top left), EP2 (top right), EP3 (bottom left), and EP4 (bottom right) in patients with aspirin-sensitive (□, n = 12), and nonaspirin-sensitive polypoid rhinosinusitis (▪, n = 10). Mann-Whitney U test.
