Outline of Final Research Achievements |
We focused on the ubiquitin-proteasome-mediated processing of ubiquitin and tumor-associated antigen (TAA) as a means of enhancing the anti-tumor effect of iPS cell-derived dendritic cell vaccines (iPSDCs), This study demonstrated that the introduction of a fusion gene of ubiquitin and tumor-associated antigen (TAA) into iPSDCs enhances TAA processing through the ubiquitin-proteasome system, thereby increasing the antigen-presenting ability of iPSDCs and enhancing their antitumor effects.

Academic Significance and Societal Importance of the Research Achievements |
iPSDCsワクチン療法はもともと生体内に備わっている抗腫瘍免疫を増強する、アクセルの働きをする。iPSDCsのワクチン効果を増強するメカニズムを解明することで、iPSDCsワクチンを臨床応用に導くことができる。それにより、既存の治療に不応の癌患者さんに対する新たな治療の開発の一助となる。 今後さらにiPSDCsワクチンの抗腫瘍効果増強のための研究を継続し、臨床応用につなげていきたい。
