Research Abstract

本研究は、Hsp90遺伝子と既知の癌抗原遺伝子との融合遺伝子を用いたDNAワクチンの有用性についての基礎的検討を行ったものである。癌抗原としては、我々が同定した癌抗原サバイビンを用いて、Hsp90-癌抗原融合遺伝子によるDNAワクチンの有効性をマウスを用いて評価した。特に癌抗原の抗原提示細胞による取り込みと抗原提示を促進する目的で、シグナルシークエンス(SS)をN末端側に付加し、分泌型としたHsp90-マウスサバイビン融合遺伝子ワクチンの有効性を検討した。その際、癌抗原サバイビンをHsp90のN末端側(SS-Survivin-Hsp90)あるいはC末端側(SS-Hsp90-Survivin)に融合した場合の、免疫効果を比較検討した。腫瘍はマウスリンパ腫細胞A20および、腎細胞癌株RenCaを同型マウスに接種し、その免疫効果を検討した。非常に興味深いことに、いずれの腫瘍においてもHsp90のN末端側に抗原を配置したSS-Survivin-Hsp90の遺伝子ワクチンでは強い抗腫瘍効果を認めたが、C末端側に配置したSS-Hsp90-Survivinでは全く抗腫瘍効果を認めなかった。またシグナルシークエンスを付加していないSurvivin-Hsp90遺伝子ワクチンと比較すると、高い抗腫瘍効果を示した。またSS-Survivin-Hsp90融合遺伝子ワクチンで免疫されたマウスでは有意なサバイビン特異的CTLが誘導されていた。この抗腫瘍効果がサバイビンに対するCTL誘導によることを示すものと考えられた。以上の結果はHsp90のC末端側が樹状細胞をはじめとする抗原提示細胞による取り込みに際して非常に重要である可能性を示唆しているものと考えられる。
