| Outline of Final Research Achievements |
We investigated characteristic immune regulation in the oral cavity using murine experimental models. Masticatory mucosae, such as the dorsal tongue, gingiva, and hard palate, physiologically expressed the immune checkpoint molecule B7-H1 and this was enhanced by various topical stimuli. We demonstrated that B7-H1 expressed on the oral mucosa directly contributed to the regulation of CD4 and CD8 T cells responding to exogenous antigens and allergens. We also found that in a contact hypersensitivity (CH) model, oral CH was more rapid and more severe, but quickly declined by the PD-1:B7-H1-mediated regulation.
