| Outline of Final Research Achievements |
Canine oral melanoma is a highly malignant tumor for which no effective systemic therapy has been established. The purpose of this study was to establish an effective immune cell therapy (CAR-T cell therapy) for oral melanoma and to establish a basic technology for CAR-T cell therapy in dogs by examining detailed conditions such as efficiency and effectiveness of CAR-T cell therapy in dogs.
Unfortunately, we were not able to produce a good CAR-T specific for oral melanoma based on the gene expression profile we obtained, but we were able to examine the conditions for the production of canine CAR-T cells and prove their efficacy in mice.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で得られた成果は、犬の悪性腫瘍に対する免疫細胞療法としてCAR-T細胞を用いる上での基礎となる情報として非常に重要である。犬のCAR-T細胞療法は、まだ未開拓分野であり、世界的にも着手しているグループは少ない。今回得られた情報をもとにさらに改良をすることにより、犬の悪性腫瘍に対するCAR-T細胞療法が臨床の現場で使用できるようになり、新たな治療オプションとなる可能性がある。
