243−4のDNA配列及びアミノ酸配列
抗体の特異性を、それぞれDNA配列及びアミノ酸配列により決定する。重鎖及び軽鎖の可変断片のDNA配列を決定した。RNAの単離のために、5×105個のハイブリドーマ細胞を、遠心分離によりペレットにし、Qiashredderカラム(#79654、Qiagen)を使用してホモジナイズした。それから、供給業者の取扱説明書に従ってRNeasy−Kit(#74124、Qiagen)を使用することにより、ホモジナイズしたハイブリドーマ細胞ペレットからmRNAを単離した。単離したmRNAに基づいて、Superscript II逆転写酵素(#18064−022、Invitrogen)を使用する逆転写によりcDNAを合成した。抗体243−4の遺伝子を、供給業者の取扱説明書に従ってAdvantage2 PCR Kit(#639206、Clontech)を使用して、合成したcDNAから増幅した。抗体遺伝子の特異的増幅は、ヒト再構成IgG可変領域遺伝子の増幅のために設計されたプライマーの組合せ(Welschof et al., 1995)の適用により保証した。重鎖可変ドメイン(VH)及び軽鎖可変ドメイン(VL)の両方の増幅のために、一組の鎖特異的順方向プライマーを、重鎖又は軽鎖の定常ドメインにおいて特異的にアニーリングする1つの逆方向プライマーと組み合わせて使用した(VH増幅 CH IgG(VH1、VH2及びVH3と組み合わせて)、VL増幅 CLλ(VLλ1、VLλ2/5、VLλ3、VLλ4a、VLλ4b及びVLλ6と組み合わせて)、表1を参照されたい)。それからPCR増幅物(amplificates)をTOPO TA Cloning Kit for Sequencing(#K457540、Invitrogen)のプラスミドpCR4−TOPOにクローニングし、最後に、精製したプラスミドDNAを、TOPO Cloning Kitのプラスミド特異的プライマー(T3及びT7、表1を参照されたい)を使用するシークエンシングのために送付した(send)(Microsynth, Balgach, Switzerland)。得られたDNA配列を、clone managerソフトウェアパッケージ(#875−501−1787、Scientific&Educational Software)を使用して加工し、整列させた。行ったアライメントから、コンセンサス配列を規定し、その後全てのヒト生殖系列の可変領域の配列のV Baseデータベース(http://imgt.cines.fr/IMGT_vquest/share/textes/)を使用して解析した。初期のシークエンシングの結果に基づいて、更なる鎖特異的な内部プライマー配列(VL−atox as及びVH−atox as、表1を参照されたい)を、先に使用したプライマーの組合せのアニーリング領域において特定した抗体配列を確認するために設計し、適用した。それにより生成された抗体遺伝子を、図1及び図2に示されるように、上で記載されるようなシークエンシングに適用した。
ヒトモノクローナル抗体243−4の抗原特異性(ELISA)
抗体243−4の抗原特異性を、ELISAアッセイにおいて細菌毒素(α毒素:#120、List Biological Laboratories、他の全ての毒素:社内で(in house)作製、Kenta Biotech AG)のパネルとの結合により評価した。各々1μg/mlの濃度の精製した毒素でコーティングしたマイクロタイタープレート(#439454、Nunc MaxiSorp)上でELISAを行った。室温で終夜のインキュベーション後、マイクロタイタープレートを0.5%BSAで2時間ブロッキングし、固定化した毒素とのmAb243−4(1μg/ml)の結合を、希釈倍率1:2000のHRP結合型ヤギ抗ヒトIgG二次抗体(#62−8420、Zymed Laboratories, Invitrogen)を用いて検出した。反応をHClで停止した。
ウエスタンブロット実験における伝染性の黄色ブドウ球菌株のα毒素との結合
12個の伝染性の黄色ブドウ球菌株からのα毒素の産生を、BHI培地(#255003、Becton Dickinson)における37℃、16時間の成長後にモニタリングした。菌株は、ドイツ黄色ブドウ球菌資料センター(ロベルトコッホ研究所、Wernigerode)から得たものであり、現在のところ黄色ブドウ球菌感染症を引き起こす最も流行している伝染性菌株を表す。これらの菌株の中には、異なるシグナル強度をもたらす他の菌株と比較して、より少ないα毒素を産生するものもある。
親和性決定(BIAcoreによる)
表面プラズモン共鳴を、BIAcore2000機器(BIAcore)を使用して測定した。全ての実験を、20mM Mops緩衝液(pH7.0)、150mM NaCl、及び0.1mg/ml BSA中で行った。最初に、ヤギ抗ヒトIgG(#81−7100、Zymed Laboratories, Invitrogen)を、BIAapplicationsハンドブックに記載されるようにアミンカップリングによりおよそ13200RUまでCM5チップ(BIAcore)上に固定化した。初期共有結合コーティングに加えて、抗体243−4を、事前に固定化した抗ヒトIgG抗体との相互作用を介してセンサーチップに結合させ、最終的に、およそ240RUの更なる固定化レベルを得た。抗原−抗体相互作用の速度論的特徴付けのために、50μl/分の流速で、漸増濃度のα毒素(3.9nM、7.8nM、15.62nM、31.25nM、62.5nM、125nM、250nM及び500nM、#120、List Biological Laboratories)のパルスを注入した。各測定サイクル(5分間の結合の後、30分間の解離)の後、10mM グリシン−HCl(pH1.7)による表面の再生により、抗体−抗原複合体を分離させた。抗体243−4の解離定数の算出のために、結合段階及び解離段階を記録し、ソフトウェアBIAevaluation4.1(BIAcore AB、図5に示されるように)を使用して全体フィッティングにより評価した。全体フィッティング解析では、これらの抗原濃度のみを考慮し、それにより、ラングミュアの1:1結合モデルに従う(≦125nM、表2)BIAcoreのマニュアルに概説されるような解析が可能となった。
ヒト肺胞細胞傷害の組織培養モデル
ヒトA549肺胞上皮細胞を、1ウェル当たり細胞数3×105個という密度でRPMI培地(#R0883、Sigma-Aldrich)中でプレート培養した。並行して、漸増濃度のα毒素(5μg/ml〜50μg/ml、#120、List Biological Laboratories)を、培地のみ、20μg/mlのアイソタイプ対照抗体(ヒトIgG1λ、精製ミエローマタンパク質、#I5029、Sigma-Aldrich)、又は20μg/mlの精製したモノクローナル抗体243−4とともにプレインキュベートした。37℃で4時間のインキュベーション後、α毒素又はα毒素−抗体溶液を細胞に添加し、インキュベーションを更に16時間継続した。その時間の後、図6に示されるように、培養培地中への細胞のLDH放出に関する計測値を提示する乳酸デヒドロゲナーゼ(LDH)アッセイ(#04744934001、Roche)により、細胞を分析した。
多臓器感染症のマウスモデル
体重27g〜31gの雌性Balb/cマウス(Charles River, Sulzfeld, Germany)を、外科処置の前に14日間順化させた。マウスは、病原体を有しない規格のものを、供給業者から得た。カテーテルの留置のために、マウスを、キシラジン(体重1kg当たり8mg)/ケタミン(体重1kg当たり100mg)を用いて腹腔内に麻酔した。上大静脈に単管ポリエチレンカテーテル(外径0.6mm、Fohr Medical Instruments, Seeheim, Germany)を留置するために、剃毛した首の左側で最小限の水平方向の皮膚切開を行った。カテーテル留置の24時間後に、マウスに1×107CFUの黄色ブドウ球菌株US300(100μl中)、及び7.5mg/kgの精製したmAb243−4又はPBS(50μl中)をカテーテルを介して投与した。2日後、処理群のマウスに第2の用量の抗体(5mg/kg)を投与し、対照群のマウスにPBSのみを投与した。外科処置の5日後、マウスを安楽死させて、腎臓の細菌量及び腎臓の膿瘍形成をモニタリングした。したがって、安楽死させた動物から腎臓を無菌的に回収し、生理食塩水中でホモジナイズした。臓器の取り出しの前に上大静脈中のカテーテルの位置を確認し、腎臓をホモジナイズする前に臓器を膿瘍形成に関して肉眼で検査した。最後に、臓器のホモジネートの段階希釈液を、MPKプレート上で37℃で少なくとも48時間培養した。コロニー形成単位(CFU)を算出し、図7に示されるように、CFU/腎臓として記録した。
