Abstract
Eosinophilic chronic rhinosinusitis (ECRS) is a refractory upper airway disease, characterized by significant eosinophil infiltration, glue-like rhinorrhea and recurrent nasal polyposis. In our previous study, we found that epithelial cell-eosinophil interactions and thrombin generated by the activation of coagulation system, stimulated the production of MUC5AC mucin and profibrotic cytokines involved in the tissue remodeling such as goblet cell metaplasia and nasal polyp formation. These actions were mediated by epidermal growth factor receptor (EGFR) transactivation of the epithelial cells, and EGFR tyrosine kinase inhibitor significantly inhibited them. We then examined (1) in vitro effects of EGFR tyrosine kinase inhibitor AG1478 on LPS- or TNF-α induced secretion of MUC5AC mucin and IL-8, and (2) in vivo effects of AG1478 on LPS- or antigen-induced goblet cell metaplasia and neutrophil/eosinophil infiltration in rat nasal epithelium. AG1478 significantly inhibited LPS- or TNF-α induced secretion and mRNA expression of MUC5AC mucin and IL-8, and intraperitoneal injection of AG1478 inhibited LPS- or antigen-induced goblet cell metaplasia, mucus production and neutrophil/eosinophil infiltration in rat nasal epithelium. Intranasal instillation of AG1478 showed similar inhibitory effects on LPS-induced changes in rat nasal epithelium. The results indicate that local administration of EGFR inhibitor may provide a new therapeutic potential for the treatment of intractable airway diseases such as ECRS.
