Outline of Final Research Achievements

This study aims to elucidate the pathology and diagnosis of oral lichen planus by analyzing exosomes in saliva. We have established a method that is simpler than the conventional method and can be stably collected in a short time for the collection of salivary exosomes. In this method, impurities are removed from saliva, ultrafiltration is performed, and size exclusion chromatography is applied. Using this method, we are conducting further studies on the saliva of healthy subjects and patients with oral lichen planus.

Academic Significance and Societal Importance of the Research Achievements

本研究はOLPの病態に、これまでに考えられていなかったエクソソームによる細胞間情報伝達が関連している可能性に着目した。その関与を明らかにすることで、新たな診断法を確立するとともに、さらにエクソソームの特徴を利用した新たな治療法の開発につなげることを目指した研究である。本研究が新たな診断・治療法確立の一助となれば、OLP患者のQOLの維持・向上に大きく貢献しうると考えられる。
