Abstract:
OBJECTIVE To explore expression of IL-13 in eosinophilic chronic rhinosinusitis with nasal polyps(EOS-CRSwNP) and further investigate the correlation between IL-13 and MUC5AC in EOS-CRSwNP. METHODS MUC5AC was detected in tissues from normal nasal mucosa and EOS-CRSwNP by immunohistochemistry and ELISA. We also used ELISA to detect the expression of IL-13 in normal nasal mucosa and EOS-CRSwNP. Correlation between IL-13 and MUC5AC in EOS-CRSwNP was investigated by correlation analysis. Secretion of MUC5AC in IL-13 incubated primary air-liquid interface(ALI)-cultured nasal polyp epithelial cells was examined by ELISA. RESULTS MUC5AC is mainly expressed in the epithelium of nasal mucosa by immunohistochemistry. By ELISA, expressions of MUC5AC and IL-13 are higher in EOS-CRSwNP than those in normal nasal mucosa. Correlation analysis shows that there exists a high correlation between MUC5AC and IL-13 in EOS-CRSwNP. IL-13 upregulates expression of MUC5AC in IL-13 incubated primary ALI-cultured nasal polyp epithelial cells for 7 or 14 days. CONCLUSION Expressions of MUC5AC and IL-13 are higher in EOS-CRSwNP than those in normal nasal mucosa respectively, and MUC5AC correlates with IL-13 highly in EOS-CRSwNP.
