IL-33 produced by immune cells derived from bone marrow stem cells is not crucial for development of HDM-induced AR.

<p>(A) H&E staining of nasal mucosa, (B) the number of eosinophils in the nasal mucosa and (C) cytokine levels in the culture supernatants of HDM-stimulated LN cells from wild-type mice injected with wild-type bone marrow (BM) cells or IL-33^−/− BM cells, 48 hours after the last inhalation of HDM (n = 10) or PBS (n = 5). Histological data show a representative result from each group (bar = 20 µm). Data show the mean + SEM. Med = Medium alone.
