Outline of Final Research Achievements

In this study, therapeutic cancer nanovaccines were developed through low-temperature self-assembly by uniformly and highly efficiently encapsulating immune-related biomolecules at the nanoscale into an iron-based metal-organic platform. After being administered into tumor-bearing mice, the nanovaccines can effectively activate the antigen-presenting cells, induce tumor antigen-specific anti-tumor immunity, and inhibit tumor growth.

Academic Significance and Societal Importance of the Research Achievements

本研究の自己組織化がんワクチンは、免疫賦活作用をもつ安価な鉄ベースの金属有機構造体に、免疫関連生体分子を均一かつ高効率的に封入することで、各成分を同一の抗原提示細胞に送達し、相乗効果を生み出すことで、免疫関連生体分子の軽減及びがんワクチン奏効率の向上につながる。従来のがんワクチンよりも合成の容易さ、免疫関連生体分子の担持効率、安定性において格段に優れており、次世代がん治療ワクチンの研究・開発に資するため、実用的・学術的波及効果が期待される。
