Description
本発明は、L1タンパク質乳頭腫ウイルスに関する。特に、本発明は、組換え乳頭腫ウイルスL1タンパク質、および乳頭腫ウイルス感染を検知し、処置するためのその使用に関する。
乳頭腫ウイルスは、ヒト、ウシ、ヒツジ、イヌおよびネコを含む一連の宿主に感染する。より完全なリストとしては、K. Syrjanen, L. Grissman および L. G. Koss 編集の乳頭腫ウイルスおよびヒトの疾患(Springer Verlag, 1987 年発行)に掲載されている J. P. Sundberg による”Papilloma Virus Infections in Animals"を参照。
本発明は、組換え乳頭腫ウイルスL1タンパク質が多重構造を細胞外に形成し、もとの乳頭腫ウイルスカプシドを認識する免疫応答を起こすとの驚くべき発見から得られたものである。
を含む5'ヌクレオチド配列を有し得る。適当な組換えDNA分子を図1に示す。

図2は、HPV6bL1HEXAHISタンパク質 凝集体の5量体構造の電子顕微鏡写真である。
本発明の種々の望ましい具体例について述べる。これらの具体例において、特殊な乳頭腫ウイルス、ワクチンおよび組換えDNA分子の構築は例示としてのみ言及されていることに注意すべきである。
実施例1:HPV6b L1 HEXAHISタンパク質の製造
pTRC6bL1の構築
HPV6bのL1開放読み取り枠を、プライマーとして:
GCGGATCCAGATGTGGCGGCCTAGCGACAGCACAGTATATG
および
CGCCCGGGTTACCTTTTAGTTTTGGCCTCGCTTACGTTTTAGG
を使用したポリメラーゼ連鎖反応により臨床的単離体からクローン化した。

アンピシリン(最終濃度100μg/ml)含有2YTブロス(トリプトン16mg、酵母10mg、NaCl 5mg)10mlに、グリセロール・ストックからの白金耳一杯(loopful)の細菌(エシェリキア・コリDH5)10μlを接種した。培養物を、120rpmで酸素供給しながら37℃で6時間インキュベートした。
細菌をグアニジニウム溶解緩衝液(6Mグアニジニウム塩酸塩および5.8ml/リットルの溶液A[177mM NaH2PO4および5M NaCl]、HClを使用してpH7.8)50mlに再懸濁し溶解した。懸濁液を2分間30%出力で超音波処理した。細胞残骸を遠心(Beckman JA21ローター、4℃で10000rpm、30分遠心)してペレット化した。HPV6b L1 HEXAHISタンパク質含有上清を保持した。
HPV6b L1 HEXAHISタンパク質を続いて、必須2工程精製工程で精製した。
HPV6b L1 HEXAHISタンパク質に対する抗体を産生させるために、マウス(C57BI/6系)に4週間の間隔で2回、表2の実験プロトコールに従って50μgタンパク質/マウスを皮下注射した。2回目の注射の2週間後、マウスから採血した。血清を標準方法を使用して抽出血液から得た。
遅延型過敏症は細胞媒介免疫応答およびある液性免疫応答を含む。マウス(BALB/c系)を、表3に概説の種々の条件下でHPV6b L1 HEXAHISタンパク質で処理(腹腔内注射)した。11日目、耳を、皮内注射でHPV6b L1 HEXAHISタンパク質または他のHEXAHISタンパク質を投与した。耳の厚さを13および14日目に測定した。14日目に陽性の反応があったマウスを殺し、耳の組織を試験した。
プレートのウェルを、PBS中、pH7.2のエシェリキア・コリ産生HPV6b L1 HEXAHIS、バキュロウイルス産生HPV6 VLP-L1ならびに対照としてバキュロウイルスおよびエシェリキア・コリ調製物(細胞発酵上清)のいずれかで0.2μgタンパク質/ウェルでコートし、一晩室温でインキュベートした。一回の洗浄をpH7.2のPBSで行った。非特異的結合をプレートを1%(w/v)カゼインで、1時間室温でインキュベートすることにより阻止した。
実験の結果は表4に示す。HPV6b L1 HEXAHISタンパク質に対する抗体と結合したHPV6b L1 HEXAHISタンパク質およびHPV6 VLP-L1の両方は、HPV6b L1 が、HPV VLP-L1で示される1個またはそれ以上のエピトープをインビボで正確に示すことを示唆する。HPV6 L1タンパク質に対する血清はまたバキュロウイルスまたはエシェリキア・コリのウェルで陰性であり、反応の特異性を示唆する。これはHPVL1 HEXAHISの、ウイルスと相互作用し、有効に中和できる抗体の誘導に好適なワクチン免疫原としての使用の支持を提供する。更に、本実施例は、ウェルにおける種々のタンパク質のコーティングにより証明された、乳頭腫ウイルスL1タンパク質の検出のための免疫検定および組換えHPV6b L1 HEXAHISタンパク質に対する抗体の使用の支持を提供する。HPV6b由来抗原の何れかを含むウェルは陽性結果であった。この実施例はまた、組換えHPV6b L1 HEXAHISタンパク質でのウェルのコーティングにより証明された乳頭腫ウイルスL1タンパク質に特異的な抗体の検出のための免疫検定およびインフルエンザウイルスA/PR−8に対する血清およびHPV6b L1 HEXAHISタンパク質に対する血清の使用の支持を提供する。この場合、HPV6b L1 HEXAHISタンパク質に対する血清を含むウェルは陽性結果となるが一方インフルエンザウイルスに対する血清は陰性である。
ウエスタン・ブロットおよびELISA実験を前記のようにまたは標準方法に従って行った。ELISA捕獲検定は以下の方法に従って行った:
(1)VLPに特異的なモノクローナル抗体(moAb 8)をマイクロタイタープレートのコーティングに使用した;
(2)HPV VLP L1タンパク質を添加し、好適な条件下でインキュベートし、0.1%トゥイン20含有PBS、pH7.4で洗浄した;
(3)種々の動物(表5のカラム1に示す)における種々の免疫原に対する抗体(表5のカラム2に示す)を添加した;および
(4)好適な検出抗原(ウサギ抗血清の場合、ヤギ−抗ウサギペルオキシダーゼコンジュゲートを使用した)を添加し、多重構造/VLP−抗体複合体を検出した。
ウェル当たりの捕獲組換え乳頭腫ウイルスHEXAHISの量を表5に示す。これらの実験は、組換え乳頭腫ウイルスL1 HEXAHISタンパク質に対する抗血清は、L1タンパク質を含む乳頭腫ウイルスVLPを認識する免疫応答を誘発することを証明する。
L1タンパク質を含む乳頭腫ウイルスVLPを認識する免疫応答を起こす乳頭腫ウイルスL1タンパク質の活性には、適切なエピトープの正しい提示を必要とする。VLPを形成しない組換え乳頭腫ウイルスL1タンパク質は、L1タンパク質を含む乳頭腫ウイルスVLPを認識する免疫応答を惹起しない。組換えGST乳頭腫ウイルスL1タンパク質、組換えMS2乳頭腫ウイルスL1タンパク質および変質乳頭腫ウイルスL1タンパク質は、L1タンパク質を含む乳頭腫ウイルスVLPを認識する免疫応答を起こさない。今まですべてのVLPは、乳頭腫ウイルスL1またはL1およびL2遺伝子の発現で細胞内に生産される。本発明の組換え乳頭腫ウイルスL1タンパク質は、L1タンパク質を含む乳頭腫ウイルスVLPを認識する免疫応答を起こす1またはそれ以上のエピトープを正しく提示する。本発明の組換え乳頭腫ウイルスL1タンパク質は、多重構造またはVLPを細胞外に形成し得る。組換え乳頭腫ウイルスL1タンパク質から形成されたVLPの多重構造は、L1タンパク質を含む乳頭腫ウイルスVLPを認識する免疫応答を起こす1またはそれ以上のエピトープを正しく提示すると、思われている。従って、本発明は、L1タンパク質を含む乳頭腫ウイルスVLPを認識する免疫応答を起こし得る多重構造またはVLPを細胞外に形成し得る組換え乳頭腫ウイルスL1タンパク質を提供する。なお、この多重構造は、複数の組換え乳頭腫ウイルスL1タンパク質からなっている。
