Outline of Research at the Start

悪性中皮腫は極めて予後不良のがんであり、現時点で治癒を期待できる治療法は存在しない。そこで本研究計画では悪性中皮腫に対する新たな治療戦略として、患者から採取した免疫細胞(T細胞)を遺伝子改変し、がん細胞を認識するキメラ抗原受容体(CAR: chimeric antigen receptor)を発現するとともにがん組織へのT細胞集積を高めるためのサイトカインやケモカインを同時に産生する次世代型CAR-T細胞を開発し、これを輸注することで強力な抗腫瘍効果を誘導することを検討する。

Outline of Final Research Achievements

Human anti-mesothelin 7x19 CAR-T cells displayed superior anti-tumor efficacy against solid cancer by their enhanced features to recruit CAR-T cells and endogenous immune cells in tumor microenvironment, compared to conventional CAR-T cells, in both orthotopic and PDX models.

Academic Significance and Societal Importance of the Research Achievements

CAR-T細胞療法は難治性の血液がんでは有用な効果を示し日本や海外で承認されているが、固形がんに対しては未だ十分な効果を示せていない。本研究結果において我々の開発した次世代型「7x19」CAR-T細胞療法はより臨床に近いヒト固形がんを用いたマウスモデルにおいて従来のCAR-T細胞療法よりも強力な治療効果を示したことから、固形がんに対する新たな治療法となることが期待される。
