| Outline of Final Research Achievements |
We established a novel mouse model of ragweed (RW) pollen-specific allergic rhinitis (AR) and examined the pathological role for endogenous IL-33 in the induction of early- and late-phase AR manifestation using IL-33-deficient mice. After nasal challenge with RW pollen, RW-immunized wild-type mice manifested early-phase (sneezing), and late-phase (eosinophilic/basophilic accumulation) responses. In contrast, IL-33-deficient and basophils-depleted mice failed to develop AR. We revealed that IL-33-stimulated mast cells and basophils contribute to sneezing and accumulation of eosinophils/basophils in the nasal mucosa by increasing histamine release and production of chemoattractants for eosinophils/basophils, respectively. Finally, compared with healthy controls, IL-33 mRNA expression in nasal epithelial cells from AR patients significantly increased during the pollen season. Thus, RW pollen-driven endogenous IL-33 and basophils are promising therapeutic target molecules to prevent AR.
