Description
キメラポリペプチドとして計画したのは、複合マルチドメインタンパク質(5つのドメイン:FliC1、FliC2、PspA、PsaA、Spr1895)である。マルチドメインタンパク質のモデル設計のため、以下の手順を用いた:ドメイン乗り込み体の見積もり、ドメイン配向を見積もるための全タンパク質モデルの構築、各ドメインについてのモデルの構築(三次元構造の例およびアブイニシオに基づくモデル設計を使用)、全タンパク質モデルを用いた各モデルの結合。
タンパク質断片PspA、Spr1895、PsaA、FliCを含むキメラタンパク質のアミノ酸配列を、ヌクレオチド配列(1623bp)に翻訳し、次いでE.コリ細胞で発現するのに最適であるように変更した。
実施例2に記載の方法に従って、肺炎球菌ワクチン製造用のヌクレオチド配列を得た。
実施例3に記載の方法に従って、肺炎球菌ワクチンを作るための遺伝子のヌクレオチド配列が生成したので、それをpET24aベクターにクローン導入した。以下の遺伝子型を有する株DH10B/R(Gibko BRL、США)由来のE.コリ細胞を、得られたプラスミドで、電気穿孔法により形質転換した:F−mcrAΔ(mrr−hsdRMS−mcrBC)φ80dlacZΔM 15 ΔlacX74 deoR recA1 endA1 araD139 Δ(ara、leu)769 galU galKλ− rpsL nupG。
実施例4に記載の方法に従って、肺炎球菌ワクチンを製造するためのタンパク質のヌクレオチド配列が得られたので、これをpET24aプラスミドにクローン導入した;得られたプラスミドをDH10B/R株由来のE.コリ細胞で増幅させ、次いで抽出した。
実施例5に記載の方法に従って、肺炎球菌ワクチン製造用のキメラタンパク質のヌクレオチド配列が得られたので、これをpET24aプラスミドにクローン導入した;得られたプラスミドをDH10B/R株由来のE.コリ細胞で増幅させ、抽出し、それを用いて、標的遺伝子発現の誘導を目的として、BL21株由来のE.コリ細胞を形質転換した。
キメラタンパク質の予防効果を見積もるため、マウスを用いた。
対照群および実験群は、7〜8週齢のメスのBalb/cマウス(体重18〜20g)30匹で構成された。マウスを肺炎球菌に感染させた:マウス1匹あたりS.ニューモニエ104cfu(コロニー形成単位)を腹部注射した(これはマウスにとって最小致死量である)。同日、キメラタンパク質10μgを各マウスに接種した。生存実験を、肺炎球菌の致死量注射の直後から開始し、14日間継続した。
Claims (1)
- ストレプトコッカス・ニューモニエのタンパク質の断片:PspA、Spr1895、およびPsaA、ならびにフラゲリン成分を含有し、これらが可動性リンカーを介して融合し、前記フラゲリン成分はアジュバントとして機能するものであり、配列番号1として表されているキメラタンパク質を含む、肺炎球菌ワクチン。
