Outline of Final Research Achievements

Development of gastric cancer therapy using oncolytic virus armed with immuno checkpoint inhibition is hopeful. We chose soluble PD-1 (sPD-1) gene for immune checkpoint inhibitory gene. We have started cloning of sPD-1 gene from c DNA library and blood sample, but we did not have obtained sPD-1 gene from neither of them. We are now continuing colonig of sPD-1.

Academic Significance and Societal Importance of the Research Achievements

本研究ではヒトsoluble PD-1 (sPD-1)遺伝子を抗がんヘルペスウイルスに導入して免疫チェックポイント阻害作用を持つ抗がんヘルペスウイルス開発を目的とし、sPD-1発現による抗腫瘍効果の増強が確認できれば動物実験を含めた前臨床的研究への発展が期待できるがsPD-1遺伝子のクローニングが予想よりも困難な状態で当初計画していた抗がんウイルス療法への応用が難しい。今後も研究継続を行うことにより抗がんウイルス療法の発展が期待される。
