Outline of Final Research Achievements |
This study includes (1) “Generation of replication-incompetent virus vaccines against influenza”, and (2) “Anti-tumor therapy using oncolytic adenoviruses in dogs. First, we successfully established MDCK cells stably expressing each HA (H1-H15), which were required to generate replication-incompetent recombinant viruses with each HA. Actually, we generated a couple of such viruses and found their immunogenicity. Second, we established adenovirus reverse genetics system based on bacterial artificial chromosome and successfully generated a bat adenovirus-recombinant virus with E1A/B deletion to assess its anti-tumor effect as an oncolytic adenovirus, which targeted dog tumors.

Academic Significance and Societal Importance of the Research Achievements |
鳥インフルエンザを防御するための1回感染型非増殖性ウイルスの構築、さらにp10分子等を同時に発現するワクチン候補ウイルスの構築は、本研究グループ以外では例がない。複数のHA亜型に対応できる多価ワクチンの構築は、新興性インフルエンザに対応できる独創的な戦略であり、本研究は今後の展開に貢献する。一方、腫瘍細胞特異的に増殖する非病原性アデノウイルスを構築し、犬の抗ガン療法としての実用化を目指すのは国内では初めての戦略である。。今回明らかになったコウモリアデノウイルスをベースとする腫瘍溶解性ウイルスの応用性は今後の研究に貢献する。
