Research Abstract |
In this study, we comparatively examined the effect of SLIT on antigen-induced airway inflammation developed in bronchoalveolar and nasal cavities in mice. Massive infiltration of eosinophils as well as neutrophils into the bronchoalveolar cavity was induced by intratracheal OVA challenge. In the nasal cavity, eosinophil accumulation was occurred, though the number of neutrophils was not significantly changed, in response to nasal antigen challenge. These antigen-induced airway inflammatory responses, including increase in the number of eosinophils and/or neutrophils in the bronchoalveolar and nasal cavities were clearly suppressed by sublingual OVA administration. This animal model displaying differential inflammatory responses in the bronchoalveolar and nasal cavities may be useful to elucidate the efficacy and mechanisms of SLIT against various allergic diseases.
