Abstract
【解決手段】工程:(a)エピトープ結合特異性を有する抗体単一可変ドメインを選択すること;および(b)工程(a)の単一ドメインをエフェクター基と連結することを含む、in vivoでの使用に適した抗体を基礎とする構造を生成するための方法。

Description
有するほとんど全ての抗原と結合するのに十分多様であると考えられる。高親和性抗体は、再編成した遺伝子の「親和性成熟」(その際、点突然変異が生成され、改善した結合に基づく免疫系によって選択される)により生じる。
本発明者らは、in vivoにおける予防および/または治療のための使用に適する、選択されたエピトープ結合特異性を有する抗体ベースの分子の合成のための単純かつ労力を要しない方法を案出した。重要なことは、この発明の方法が所望のもしくは予め決定したエピトープ結合特異性を有する単一鎖抗体ベースの分子の合成を可能にすることである。この単純な方法の使用は、重鎖のみの抗体の治療的使用に反する内容を教示するH鎖病の先行技術に照らせば驚くべきことである。
(a)エピトープ結合特異性を有する抗体単一可変ドメインを選択すること;および
(b)工程(a)の単一ドメインを免疫グロブリンエフェクター基と連結すること、
を含むin vivoでの使用に適した単一ドメイン−エフェクター基免疫グロブリン(dAb−エフェクター基)を合成する方法を提供する。

定義
免疫グロブリン これは抗体分子に特徴的な免疫グロブリン折りたたみを保持するポリペプチドのファミリーを指し、2つのβシート、および通常保存されたジスルフィド結合を含む。免疫グロブリンスーパーファミリーの構成メンバーはin vivoで細胞および非細胞相互作用の多くの局面に関与し、これには免疫系における広範囲にわたる役割(例えば、抗体、T細胞レセプター分子など)、細胞接着(例えばICAM分子)および細胞内シグナル伝達(例えば、PDGFレセプターなどのレセプター分子)における関与が含まれる。
一般的技術
他に定義されていない限り、本明細書で使用される(例えば細胞培養、分子遺伝学、核酸化学、ハイブリダイゼーション技術および生化学における)全ての技術および科学用語は当業者に共通して理解されるものと同一の意味を有する。標準技術は分子法、遺伝子法および生化学法(一般的にSambrookらMolecular Cloning:A Laboratory Manual, 第2版(1989) Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y.およびAusubelらShort Protocols in Molecular Biology(1999)第4版,John Wiley & Sons,Inc.を参照し、これらは参照により本明細書に組み入れる)ならびに化学法について用いられる。
dAb−エフェクター基は既に確立された技術に従って調製でき、このような技術は抗体工学の分野で、scFv、「ファージ抗体」および他の人工抗体分子の調製のために使用される。抗体、および特に二重特異性抗体を調製するための技術は、例えば以下の総説およびこれらの中に記載される参考文献中に記載されている:Winter & Milstein(1991) Nature 349:293-299; Plueckthun(1992)Immunological Reviews 130:151-188;Wrightら(1992) Crti.Rev.Immunol.12:125-168;Holliger,P. & Winter,G. (1993) Curr. Op.Biotechn.4, 446-449; Carterら(1995)J.Hematother. 4, 463-470; Chester,K.A. & Hawkins,R.E.(1995)Trends Biotechn.13, 294-300; Hoogenboom,H.R.(1997) Nature Biotechnol.15, 125-126; Fearon,D.(1997)Nature Biotechnol.15, 618-619; Pluckthun,A. & Pack,P.(1997)Immunotechnology 3, 83-105; Carter,P. & Merchant,A.M. (1997) Curr.Opin.Biotechnol.8, 449-454; Holliger,P. & Winter,G.(1997) Cancer Immunol. Immunother. 45, 128-130。
多様な選択システムが当業界で公知であり、これらは本発明における使用に適している。そのようなシステムの例を以下に記載する。
選択に使用することが意図されるライブラリーは、例えば上記のような当業界で公知の技術を用いることにより構築してもよく、もしくは商業的に購入してもよい。本発明に有用なライブラリーは、例えばWO99/20749に記載されている。いったんベクター系が選択され、かつ目的のポリペプチドをコードする1以上の核酸配列がライブラリーベクター中にクローニングされれば、発現前に突然変異誘発を行うことによってクローン分子内で多様性を生じさせることもでき、あるいは、突然変異誘発と選択の追加ラウンドを実施する前に、コードされるタンパク質を上述されるように発現および選択してもよい。構造的に最適化されたポリペプチドをコードする核酸配列の突然変異誘発は標準的な分子法によって実施される。特に有用な方法はポリメラーゼ連鎖反応、もしくはPCRである(MullisおよびFaloona(1987) Methods Enzymol.,155:335、参照により本明細書に組み入れる)。耐熱性DNA依存性DNAポリメラーゼにより触媒される複数サイクルのDNA複製を使用して、目的の標的配列を増幅するPCRは当業界で周知である。様々な抗体ライブラリーの構築がWinterら(1994) Ann.Rev.Immunology 12, 433−55およびその中に記載される参考文献中で議論されている。
いったん選択された本発明によるドメインは、当業界で公知の多様な方法(共有結合および非共有結合的方法)で本明細書に記載されるエフェクター基と連結することができる。
本発明によれば、単一のVHおよび単一のVL可変ドメインは本明細書に記載される手段を介してエフェクター基と連結される。
本発明によるdAb−エフェクター基は本来抗体を産生するあらゆる種に由来するか、または組換えDNA技術によって作製し得る(血清、B細胞、ハイブリドーマ、トランスフェクト細胞(transfectomas)、酵母もしくは細菌のいずれかから単離される)。
本明細書で定義される単一ドメイン抗体−エフェクター基(dAb-エフェクター基)とは、1以上の定常領域ドメイン(エフェクター基)と連結した、1以上のエピトープと特異的に結合可能な単一可変ドメインを含む設計された抗体分子をいう。各可変ドメインは重鎖ドメイン(VH)もしくは軽鎖ドメイン(VL)であってもよい。
各単一可変ドメインは、免疫グロブリン足場およびドメインと1以上のエピトープとの特異的相互作用に関与する1以上のCDRを含む。
免疫グロブリンスーパーファミリーの構成メンバーは全てこれらのポリペプチド鎖について類似した折り畳み(fold)を共有する。例えば、抗体はこれらの一次配列については高多様性であるが、配列および結晶構造の比較は予想に反して抗体の6種の抗原結合ループのうち5種(H1、H2、L1、L2、L3)が限られた数の主鎖コンホメーションもしくは標準構造をとることを明らかにしている(ChothiaおよびLesk(1987) J.Mol.Biol.,196:901; Chothiaら(1989) Nature、342:877)。したがって、ループ長および鍵となる残基の分析は、大部分のヒト抗体でみられるH1、H2、L1、L2およびL3の主鎖コンホメーションの予測を可能にしている(Chothiaら(1992) J.Mol.Biol.,227:799; Tomlinsonら(1995) EMBO J.,14:4628; Williamsら(1996) J.Mol.Biol.,264:220)。H3領域は(Dセグメントの使用に起因して)配列、長さおよび構造に関して遥かに多様であるが、また短いループ長について限られた数の主鎖コンホメーションを形成し、これは長さおよびループと抗体フレームワーク中の鍵となる位置に存在する特定の残基もしくは残基のタイプに依存する(Martinら(1996) J.Mol.Biol.,263:800; Shiraiら(1996) FEBS Letters, 399:1)。
所望の多様性は典型的には1以上の位置で選択される分子を改変することによって生成される。変化されるべき位置は無作為に選択することができ、または選択されることが好ましい。次いで、変異は、常在アミノ酸が任意のアミノ酸または天然もしくは合成のその類似体と交換される間の無作為化によって非常に多数の変化を産生することにより、または常住アミノ酸を規定のアミノ酸の部分集合の1以上で置換して、より限定数の変異体を産生することにより達成することができる。
本発明による単一ドメイン抗体−エフェクター基(dAb−エフェクター基)のその特異的抗原もしくはエピトープへの結合は、ELISAを含む当業者によく知られた方法で試験することができる。好適な実施形態では、結合はモノクローナルファージELISAを用いて試験される。
一般的に、本発明の実行に要求される核酸分子およびベクター構築物は、Sambrookら(1989) Molecular Cloning: A Laboratory Manual、Cold Spring Harbor、USAなどの標準的な実験室マニュアルに示されるように構築および操作することもできる。
本発明の方法に従って選択されるdAb−エフェクター基はin vitro治療および予防用途、in vitroおよびin vivo診断用途、in vitroアッセイおよび試薬用途などに使用してもよい。例えばdAb−エフェクター基をELISA技術など当業者に公知の方法に従って抗体に基づくアッセイ技術において使用してもよい。
この実施例はVκ−FcおよびVH−Fc融合体(いずれの融合体についてもFcはIgG1に由来し、Fcはヒンジ−CH2−CH3である)を作製する方法を説明する。β−ガラクトシダーゼ結合性VκdAb E5をVκ−Fc融合体を作製するために用い、アルカリホスファターゼ(APS)結合性VHdAb VH2をVH−Fc融合体を作製するために用いた(VκdAb E5およびVHdAb VH2の配列は表1aに示される)。
この実施例はE5−FcおよびVH2−Fc融合体(実施例1)を哺乳動物細胞中で発現させることができ、かつ産生したタンパク質が親dAbの抗原特異性を維持していることを説明する。
この実施例はE5−Fc融合タンパク質がヒトFcレセプターを発現する細胞系に結合することができることを説明する。精製したE5−Fcタンパク質をフルオレセイン(3.3/1のフルオレセイン/タンパク質比率で)で標識した。その後、標識したタンパク質(491μg/ml濃度)をFACS分析に用いた。二種類のタイプのヒトFcRs(CD64およびCD32)を発現するヒト単球様U937細胞を用いてE5−Fc融合タンパク質がこれらのレセプターに結合する能力を評価した。FACS結果はE5−Fc融合タンパク質がU937細胞系(5x105個のU−937細胞を80μlの標識タンパク質(1:50希釈)と共にインキュベートし、ライブで調査した)に結合することを示している(図4)。U−937細胞におけるレセプターブロッキング調査は、E5−Fc鎖が主にCD32レセプターに結合することを示した(データは示されない)。この結果を確認するため、Raj 1細胞(CD32レセプターのみを発現する)をFACS分析に用いた。FACS結果はE5−Fc鎖がRaj 1細胞に結合することを立証する(図5)。
薬物動態学的分析のために、6群のオスCD1マウス3個体(年齢は約6〜7週間;体重は約25〜30g)を50μgのdAb−Fc(実施例1に記載されるE5−Fc)を用いて尾静脈に静脈内(i.v.)注射した。E5−Fcタンパク質を実施例2に記載される哺乳動物細胞系から精製し、500容量のリン酸緩衝生理食塩水に対して2時間以上2回透析した。6群のオスCD1マウス3個体(年齢は約6〜7週間;体重は約25〜30g)を50μgのdAb(C末端HAエピトープタグを有するHEL−4と称する抗メンドリ卵リゾチームdAb、アミノ酸配列については下記を参照のこと)を用いて尾静脈に静脈内注射した。HEL−4は大腸菌株HB2151中で発現され、プロテインAおよび陰イオン交換を用いた標準的なクロマトグラフィーによってペリプラズム画分から精製した。このタンパク質を500容量のリン酸緩衝生理食塩水に対して2時間以上2回透析した。
本明細書で言及されるように、TAR1−5−19は標的ヒトTNFα(TAR1)に特異的に結合するDabである。
ベクター構築
ピキアにおけるdAb Fc融合タンパク質のメタノール誘導性、分泌性発現のためのベクターを、発現ベクターpPICZalpha(Invitrogen)に基づいて構築した。このベクターをXbaIとKpnIによる消化によって改変して、1247位のヌクレオチドでXhoI部位を除去し、Pfuポリメラーゼで平滑末端化して再連結した。ヌクレオチド1315位のSalI部位をSalIにより消化することにより除去し、Pfuポリメラーゼで平滑末端化して再連結した。続いてVK dAb−Fc融合体を、下記のプライマーおよびPfuTurbo DNAポリメラーゼ(Stratagene)を用いて上述される哺乳動物発現構築物からPCR増幅した。
ピキアをエレクトロポレーションのために、0.51YPD(1%(w/v)酵母エキス、2%(w/v)ペプトン、2%(w/v)グルコース)培地中30℃で1.0のOD600nmまでピキア・パストリスを生育することによりコンピテント化した。その後、この細胞を氷冷水で2回、20mlの氷冷1Mソルビトールで1回洗浄し、1mlのソルビトール中に再懸濁した。生じた懸濁液の80マイクロリットルを上述されるように作製した10μgのPmeI線状化ベクターを含む水の10マイクロリットルと共に氷上で5分間インキュベートし、続いて0.2cmの電極ギャップエレクトロポレーションキュベット中で(0.54kV、25ミクロファラド)、キャパシタンス拡張装置を備えたBiorad gene pulserII(Biorad)における無限大の抵抗設定でエレクトロポレートした。細胞を1mlの1Mソルビトール中に回収し、続いて100、500、1000もしくは2000μg/mlのゼオシンで補足したYPDSプレート(1.5%(w/v)寒天中、1%(w/v)酵母エキス、2%(w/v)ペプトン、2%(w/v)グルコース、1Mソルビトール)上にプレーティングした。プレートを2〜3日間30℃で生育し、続いてコロニーを再塗布して(re−streaked)クローン集団を単離した。その後クローンを下記に記載されるように発現レベルについて特徴付けた。
発現は、バッフル振とうフラスコにおいて、炭素源としてグリセロールを含む合成BMGY培地(1%(w/v)酵母エキス、2%(w/v)ペプトン、1%(v/v)グリセロール、1.34% (w/v)酵母窒素塩基、4x10−5%(w/v)ビオチン、100mM KPO4バッファー pH6.0)中で実施した。培養物を250rpmで振とうしながら30℃で10のOD600nmまで生育し、続いてペレットを遠心分離により回収し、発現を誘導すべくBMMY(1%(w/v)酵母エキス、2%(w/v)ペプトン、0.5%(v/v)メタノール、1.34%(w/v)酵母窒素塩基、4x10−5%(w/v)ビオチン、100mM KPO4バッファー pH6.0)中に再懸濁した。30℃での誘導後24〜48時間で30mg/mlのピーク発現レベルが観察された。
精製を20分間、4℃で2000xgでの遠心分離により浄化した上清において行った。上清を20cmの深さのベッドの流線型プロテインAマトリックス(Amersham Biotech)上に300cm/時間で装填した。装填の後、結合していない物質を0.35M NaClで補足されたPBSを用いて洗浄することで除去した。融合タンパク質を0.1M グリシン、0.15M NaCl、pH 3.0により溶出した。分画を0.2容量の1M Tris−HCl、pH 8.0で中和した。純粋なdAb−Fc融合体を、5mlのResource Qカラム(Amersham Biotech)上で(20mM Tris−HClバッファー、pH8.5、0〜0.5MのNaCl勾配を用いた)イオン交換クロマトグラフィーによってこの物質からさらに精製した。
結果は図13に示される。
アミノ末端の配列決定は、このタンパク質が5サイクルのエドマン分解後にピキア・パストリスのKex2プロテアーゼによって予測されるように処理されて、NH2−EDQIMのアミノ末端配列を生じていたことを示した。
結果は図12に示される。
産生されたこのタンパク質は、以下のアッセイによって測定されるように、抗原の結合後にヒトの補体の活性化に有効であった。
