発明の詳細な説明
AIDS研究の一つの主要なゴールはHIV−1ウイルスに対するワクチンを開発することである。有効なワクチンは強い体液性応答に加えて、有効で広範囲のCTL応答を惹起しなければならない。このことはHIV−1ウイルスの遺伝子異質性のため面倒なことである。HIV−1逆転写酵素(RT)は間違いを起こしがちであり、および校正する能力が欠如しており、ゲノム当たり、サイクル当たりで10-4の突然変異率を示している。Dougherty,et al.,J.Virol.,62,2817。HIV−1ゲノム配列変異が、異なった個体から単離されたウイルス並びに異なった時間点で単一の個体から単離されたウイルスで観察されている。Fisher,etal.,Nature,1988,334,444およびMeyerhans,et al.,Cell,1989,58,901。多数の配列分析データに基づくと、中和抗体および/またはCTLエピトープを変化させることにより患者における逸脱変異体ウイルスを導く突然変異の主たる標的は構造遺伝子env、gagおよびpolであることは明らかである。Pircher,etal.,Nature,1990,346,629;Reitz,et al.,Cell,1988,54,57;およびWolfs,et al.,Virol.,1991,185,195。このことにもかかわらず、初期の実験はHIV−1の構造および酵素遺伝子は異なった動物モデルにおける核酸に基づいたワクチンとして成功裡に使用できることを示しており(Wang,etal.,Proc.Natl.Acad.Sci.USA,1993,90,4156;およびWang,etal.,,AIDS,1995,9(Suppl A),S159)、DNAワクチンのための予防的並びに治療的研究が開始された。本発明は免疫原カセットとしてのvif(HIV−1補助遺伝子)の開発に関している。他のHIV−1遺伝子と併せて使用した場合、すべてのウイルス成分に対する広範囲な免疫応答が誘導され、生きている弱毒化ワクチンにより誘導される免疫応答の多くの様相を模倣している。
実施例3:DNA調製およびPCR増幅 高分子量(ゲノム)DNAは感染PBLから調製され、Velpandi,et al.,J.Virol.Meth.,1990,29,291(本明細書において援用される)に記載されているようなPCR技術により増幅された。手短に言えば、PCR混合物は5から10μgのゲノムDNA、50mM KCl、2.5mM MgCl2、10mMトリス/HCl(pH8.0)、800μM dNTPs、2.5単位Taqポリメラーゼ、20pmolオリゴヌクレオチドプライマーおよび二重脱イオン水(ddH2O)(最終容量を100μlとする)を含んでいる。反応温度およびサイクル時間は以下のようである:94℃−変性(1分)、55℃−アニーリング(1.5分)および72℃−伸張(2分)。サイクルは35回繰り返された。プライマー配列は以下のようである:Vif(+)5’−GAAAGCTTATGGAAAACAGATGGCAG−3’(5046−5065)(配列ID番号:2);およびVif(−)5’−GCAAAGCTTTCATTGTATGGCTC−3’(5609−5626)(配列ID番号:3)。クローニング目的のためプライマーはHindIII制限部位(ボールド体)が設けられた。
実施例21:臨床HIV−1単離物で感染させたヒト標的を用いるインビトロでの細胞性応答の評価ウイルス感染標的の溶解を誘導するvifクローンの能力を評価するため、CTLアッセイの標的として、CD4レセプターおよびマウスクラスIH−2Dd制限要素の両方を発現するHIV−1感染可能ヒーラーCD4/Dd細胞が使用された。これらの細胞は7日間、症候性AIDSの患者から誘導されたHIV−1単離物で感染させた。図5(A−D)はCTLアッセイの結果を示している。vif特異的溶解を示す各々のDNA構築物を注射したマウスから脾臓細胞が得られた。クローンT−35、N−15およびpCVifは50:1のエフェクター:標的比で各々27、26および24%溶解を示した。25:1の比では3つすべてのクローンが20%溶解を示した。このことは、天然のHIV−1に対する細胞性免疫応答はvif発現ベクターによる遺伝子ワクチン接種により発生できることを示している。
