Outline of Final Research Achievements

Salivary immunoglobulin (secretory IgA antibodies) plays a role in preventing oral infections such as periodontal disease. To induce secretory IgA into saliva is the effective approach in the prevention and treatment of periodontal disease. Investigation of seeking the genes that control the production of secretory IgA was conducted in this study, using ENU mouse mutagenesis that can detect functional mutation in mouse genome. As a result, the mutation named “Yummy”was isolated in the screen of the amount of the secretory IgA in mouse saliva. Genome-edited mice with yummy mutation was created and further study of the gene function of it is to be conducted in the future.

Academic Significance and Societal Importance of the Research Achievements

歯周病の高い罹患率を減少させるアプローチの一つとしてワクチン開発があり,口腔内において効果的に病原菌に対する分泌型IgAを産生することが求められる。本研究では2011年『ノーベル医学生理学賞』を受賞し,世界的高水準の研究室,研究機関を運営する,Dr. Beutler研究室との共同研究により,最先端のENUミュータジェネシスの手法を応用し,新たに分泌型IgA産生を制御する遺伝子を同定した。この分子をターゲットとした,感染症予防や歯周病医薬およびワクチンの開発の可能性が将来的に期待される。
