Outline of Final Research Achievements

Recent studies about the concept of immunogenic cell death suggested that it would be possible to prepare effective vaccine by live tumor cells but not formalin fixed- or frozen-tumor tissue. In this project, we established the method to prepare a novel cell based vaccine using original designed adjuvant “lipopeptide adhering to cell surface by a charge-dependent manner”.
On the other hand, we succeeded in identifying some candidate molecules as cancer vaccine-related immunogenic factors in vaccine cell line. We are planning to apply these findings for the next cancer vaccine strategy as a novel perspective of drug discovery.

Academic Significance and Societal Importance of the Research Achievements

患者固有がん細胞としての性質を維持したまま試験管内で培養する技術が開発され、その研究成果を患者へ還元する方法として、遺伝子診断や有効治療薬の評価など、個別化医療への応用が期待されている。本研究課題では、申請者のオリジナル創薬戦略から設計した人工アジュバント「電荷依存的に 細胞接着するリポペプチド」と患者由来の培養がん細胞を「がん抗原」として利用する。これまでに考案されてきたワクチン戦略では対応できなかった、患者がん細胞の多様性を克服し、さらに強力な免疫活性化を誘導する新規がんワクチンを、個別化医療の新たなアウトプットとして提供する研究である。
