| Outline of Final Research Achievements |
Sublingual immunotherapy (SLIT) is an allergen-specific treatment for allergy. SLIT operates by acting on the sublingual mucosa and increases allergen tolerance with safety and effective effect. However, the underlying immunological mechanism remain unclear. This study aimed at providing evidence that sublingual immune tolerance is induced by cross-talking with gut mucosal immunity. This study showed that after sublingual application of antigen, antigen was captured by macrophages, transferred to migratory dendritic cells, and antigen-specific regulatory T cells were induced in the draining (submandibular) lymph modes. This study also showed that Langerhans cells in sublingual mucosa were not responsible for the induction of sublingual immune tolerance, and that sublingual immune tolerance was related to intestinal immune tolerance.
