Research Abstract

アデノ随伴ウイルス(AAV)ベクターの開発とその特徴を活かした癌遺伝子治療法の基礎研究を行った。
1.バキュロウイルスを利用したAAVベクターの作製とAAVベクター改変に関する基礎的検討:ベクターゲノムのパッケージング効率を高める検討では、大きな進展はなかった。AAVベクターの改変に関して、5型のAAVベクターのキャプシド蛋白質VP1の一部をドメインごとに2型の対応する部分に置き換えたキメラGFPベクターを計6種類構築した。これらの293細胞での発現強度はどれもほぼ同程度であった。以上より、VP1特異的領域が比較的変異を導入しやすいことが分かった。
2.AAVベクターを用いた遺伝子導入法に関する基礎検討:各種血清型AAVに対する中和抗体の力価と、サル門脈内へのAAVベクター投与による肝臓への遺伝子導入効率への影響につき検討を行った。その結果、検出限界程度の低力価中和抗体であっても、遺伝子導入効果を著しく阻害することが明らかとなった。一方、中和抗体陰性の個体では遺伝子導入効率は良好であった。AAVベクターの血管内投与では中和抗体の影響が強く出るものと考えられた。
3.AAVベクターを用いた癌に対する遺伝子治療ストラテジーの検討:子宮体部癌リンパ行性転移モデルを用いて、sFlt-4発現AAVベクターの効果を検討した。その結果、同ベクターの筋肉内投与により、リンパ節転移のほぼ完全な抑制が認められた。このモデルでは肺転移も同時に認められたが、治療群では肺転移も著明に抑制されており、リンパ行性のものが主体であることが示唆された。尚、原発巣に対する抗腫瘍効果は認められず、sFlt-1による腫瘍血管の抑制の場合と異なったパターンの治療効果が得られることが判明した。
