Outline of Final Research Achievements

Mucosal vaccine is widely considered as next-generation vaccines to combat infectious diseases. However, there are no subunit-type mucosal vaccines in clinical settings. Therefore, we aimed to develop a mucosal vaccine system using a nitric oxide donor. In this study, we found that intranasal administration of a nitric oxide donor in combination with an antigenic protein potentiated antigen-specific both mucosal IgA and systemic IgG. Furthermore, this system was considered to be safe, as inflammatory reactions and weight loss were not observed.

Academic Significance and Societal Importance of the Research Achievements

新型コロナウイルスのパンデミックは人類の感染症に対する脆弱さを痛感させた。生命のみならず社会秩序および経済を守るためには効果的な粘膜ワクチンの開発が必要不可欠であると思われる。本研究により見いだされた一酸化窒素供与体を用いたサブユニット型の粘膜ワクチンシステムは、粘膜ワクチンの新しいモダリティとなり得ると考えられた。さらなる研究開発によって多くのワクチンモダリティの一翼を担うことで社会に貢献することが期待される。
