Outline of Final Research Achievements |
To clarify the mechanisms of immune responses in the oral mucosa, we analyzed the properties, constituent cells, and functional roles of immune cell clusters in the sublingual mucosa. The clusters in steady state contained regulatory T cells (Treg), unlike other tissues. The subsets of constituent T cells significantly changed depending on the immune responses. The coexistence of a subsets of dendritic cells, which were able to activate these T cells, suggested that the clusters had a local immunomodulatory mechanism. These findings may lead to the elucidation of the mechanisms of sublingually administered vaccines and sublingual immunotherapy.

Academic Significance and Societal Importance of the Research Achievements |
本研究の結果は、舌下粘膜に存在する免疫細胞の集積(クラスター)特徴的な性状の詳細を解析した。この結果は、口腔粘膜における免疫応答の機構を理解するのに有益な情報を与えると考える。さらにI型アレルギー疾患の治療法として近年注目されている舌下免疫療法や、これからのワクチンとして有望視されている舌下投与ワクチンのメカニズム解明につながり、さらにはこれらのより効率良い療法、投与法の開発につながるものと考えている。
