| Research Abstract |
Allergic rhinitis has been defined as the inadequate peripheral regulation of allergen-specific T cells in individuals. In this study, we investigated the suppressive effect of RNA interference to allergen-specific Th responses and regulatory T cell responses in patients with allergic rhinitis. The suppressive effect to allergen-specific Th2 responses and regulatory T cell responses by RNA interference was not sufficient. On the other hand, our findings showed that regulatory T cells predominantly suppressed Th1 responses rather than Th2 responses, where allergen-specific IL-10-producing regulatory T cells might be responsible for the down-regulation of allergen-specific responses.
