Outline of Research at the Start

本研究では、テロメラーゼ依存性アデノウイルスOBP-301(Telomelysin)に多機能がん抑制遺伝子であるp53を搭載した次世代型武装化ウイルス製剤 OBP-702(Pfifteloxin)の膵癌間質細胞による免疫抑制機構への効果を検証し、臨床試験用ロットの大量製造が進む本製剤の難治性膵癌を対象とした実用化を目指す。特に、がん関連線維芽細胞(cancer-associated fibroblast; CAF)の免疫抑制分子であるTGF-β発現調節や免疫活性化に繋がるPTENがん抑制遺伝子の膵癌細胞での発現調節に着目してin vitroおよびin vivoでの解析を進める。

Outline of Final Research Achievements

We examined the effect of OBP-702, a next-generation armed adenovirus OBP-702, which carries the multifunctional tumor suppressor p53 gene, on the immunosuppressive pancreatic cancer microenvironment. Pancreatic cancer stromal cells (human pancreatic stellate cells: hPSC) promoted tumor growth by coexisting with pancreatic cancer cells in the pancreatic cancer microenvironment, and OBP-702 produced strong p53 gene expression in hPSC. By inducing selective apoptosis, in addition to the antitumor effect on the pancreatic cancer cells, OBP-702 exhibited a profound antitumor activity through the control of the pancreatic cancer microenvironment.

Academic Significance and Societal Importance of the Research Achievements

膵癌微小環境において、膵癌間質細胞hPSCは膵癌細胞と共存することで腫瘍増殖を促進しており、OBP-702は膵癌細胞自体への抗腫瘍効果に加えて膵癌微小環境の制御を介した統合的な抗腫瘍活性を発揮した。間質細胞を標的とすることで他の種々の細胞とのクロストークに関わる様々な分子を制御することができ、がん細胞のみを狙った既存のコンセプトとは異なる革新的な治療法の開発につながる可能性がある。
