Description
天然に存在しているような完全長抗体は、ジスルフィド結合によって相互接続されている2本の重(H)鎖および2本の軽(L)鎖を含む免疫グロブリン分子である。各鎖のアミノ末端部分は、可変領域に含まれる相補性決定領域(CDR)を介して抗原認識に主に関与する約100〜110個のアミノ酸の可変領域を含む。各鎖のカルボキシ末端部分は、エフェクター機能に主に関与する定常領域を規定する。
アミノ酸が以下のカテゴリーの範囲内にある場合、使用されるヒト生殖細胞配列のフレームワークアミノ酸(「アクセプターフレームワーク」)は、親抗体化合物のフレームワーク(「ドナーフレームワーク」)由来のフレームワークアミノ酸に置換される:
(a)アクセプターフレームワークのヒトフレームワーク領域におけるアミノ酸は、その位置におけるヒトフレームワークには稀であるが、ドナー免疫グロブリンにおける対応するアミノ酸は、その位置におけるヒトフレームワークに典型的である;
(b)アミノ酸の位置はCDRの1つに直接隣接している;または
(c)フレームワークアミノ酸の任意の側鎖原子は、三次元免疫グロブリンモデルにおいてCDRアミノ酸の任意の原子の約5〜6オングストローム(中心〜中心)内である。
抗体I、II、IIIおよびIVは以下のように生成し、精製できる。HEK293EBNAまたはCHOなどの適切な宿主細胞を、最適な所定のHC:LCベクター比を用いて抗体をスクリーニングするための発現系、または配列番号23、もしくは配列番号24などのHC、および配列番号25、配列番号26、配列番号27、もしくは配列番号28などのLCの両方をコードする単一のベクター系で一過性または安定にトランスフェクトする。清澄培地(その中に抗体が分泌される)を、多くの一般に使用される技術のいずれかを用いて精製する。例えば、培地は、リン酸緩衝生理食塩水(pH7.4)などの適合性バッファーで平衡化されているプロテインAまたはGセファロースFFカラムに簡便に適用することができる。カラムを洗浄して非特異的結合成分を除去する。結合した抗体を、例えばpH勾配(例えば0.1Mリン酸ナトリウムバッファー、pH6.8から0.1Mクエン酸ナトリウムバッファー、pH3.0)によって溶出する。抗体画分をSDS−PAGEなどにより検出し、次いでプールする。意図する使用に応じて、さらなる精製を任意にする。抗体を一般的な技術を用いて濃縮および/または濾過滅菌し得る。可溶性会合体および多量体を、サイズ排除、疎水性相互作用、イオン交換、またはヒドロキシアパタイトクロマトグラフィーを含む、一般的な技術によって効果的に除去し得る。これらのクロマトグラフィー工程の後の抗体の純度は99%より高い。産生物は−70℃ですぐに凍結してもよいか、または凍結乾燥してもよい。これらの抗体についてのアミノ酸配列を以下に提供する。
結合平衡を確立するために、定濃度の抗体を、PBS(pH7.4)+1mg/mLのウシ血清アルブミン(「BSA」)またはバッファーのみにおける種々の濃度のHis標識化DKK−1(配列番号29、配列番号30、配列番号31、配列番号32、または配列番号33)(1nM〜1pM範囲)と混合し、37℃で数日間インキュベートする。2セットの結合反応物(1セットは低濃度の抗体(3pM)および1セットは高濃度の抗体(30または50pM))を設定する。
標準的なWntシグナル伝達は骨芽細胞分化および活性に重要である。BMP−4と混合したWnt−3a CM(馴化培地)は、多能性マウスC2C12細胞を誘導して、アルカリホスファターゼ(「AP」)、骨芽細胞活性のマーカーの測定可能なエンドポイントを有する骨芽細胞に分化する。DKK−1、標準的なWntシグナル伝達の阻害剤は、APの分化および産生を阻害する。DKK−1抗体を中和することにより、APのDKK−1媒介性阻害が防止される。DKK−1阻害活性を遮断する抗体はAP活性の損失を防止する。
6ヶ月齢の雌のSprague−Dawleyラットを卵巣切除し、2ヶ月間骨を損傷させる。2mm直径の欠損を、2mmの歯科用ビットを備える電気ドリルを用いて左および右の大腿骨に導入する。この穴は前部皮質および後部皮質の両方に広がる。骨の治癒を、外科手術後35日間、定量的コンピュータ断層撮影(「qCT」)を使用して骨量密度(「BMD」)を評価することによって長期的にモニターする。実験の終わりに、動物を屠殺し、大腿骨全体を、骨幹全体の生化学的強度を確認するために欠損までの負荷(loaded−to−failure)の測定に供する。抗体を示した用量および間隔で皮下に投与する。
マウス(雌のC.B−17マウス、Fox Chase重症複合免疫不全モデル#CB17SC−M)を、実験開始前に動物施設において1週間順化する。順化後、マウスを処置あたり10の群に無作為化する。培養したヒトA549非小細胞肺癌細胞を、マウスのひ腹に皮下移植し、腫瘍を平均腫瘍体積約100mm3に到達させる。抗体II(1mg/kgおよび5mg/kg)、コントロールIgG抗体(1mg/kgおよび5mg/kg)、または賦形剤(0.02%のTween80を補足したクエン酸緩衝生理食塩水)を皮下注射により投与する。動物に7日間隔で2回処置を与える。
抗腫瘍効果の機構を理解するために、ハイコンテントイメージング分析を、抗体IIまたはIgGコントロールで処置したA549腫瘍で実施する。数個の表現型に基づいたマーカーを、定量的および定性的の両方で分析して、血管形成(CD31および平滑筋アクチン、SMA)、低酸素症誘発(グルコース輸送体1、GLUT1)、細胞増殖(Ki67)、およびアポトーシス(Terminal UDP Nick−End Labeling,TUNEL)の癌関連生物学的プロセスを評価する。
インプラント周辺の骨形成を促進し、骨組織を再生する抗体V(軽鎖配列番号34および重鎖配列番号35)の能力を評価するために、体重約425gの4か月齢の雄のSprague−Dawleyラット(Harlan Sprague Dawley Inc)を利用する。ラットに、チタンネジ(2mm×4mm)を脛骨−腓骨連結部上の両下肢の右外側の中膜に外科的に埋め込む。次いで、ラットを体重によって無作為に2つの群に分け、10mg/kgの抗体Vまたは10mg/kgのIgGコントロールのいずれかを、21日間、外科手術の同じ日に開始して1週間に1回皮下注射を与える。定量的コンピュータ断層撮影(Aloka LaTheta LTC−100モデルCTスキャナー)を、生体外で走査するために使用し、60μmのボクセルサイズの新しく形成された骨を定量する。目的の体積(VOI)を、以前のインプラント部位にわたって0.1mm間隔で28スライスと定義する。群の相違を、JMPバージョン5.1.ソフトウェア(Cary,North Carolina)を用いて評価し、p<0.05の有意なレベルでダネット法を使用してIgGコントロールと比較する。生体外でのファキシトロン(faxitron)x線画像による定性的評価により、抗体Vで処置したラットが多くの新しい骨またはインプラント周辺に仮骨を有することが示される。定量的CT分析により、IgGコントロールと比べて抗体Vで処置したラットにおいて、皮質インプラント周辺の骨塩量(14%)、新しい骨領域(16%)、皮質厚(7%)ならびに骨髄海綿状インプラント周辺の新しい骨塩量(18%)および骨領域(16%)の統計的に有意な増加が明らかにされる。このデータにより、抗体Vが、チタンを埋め込んだラットにおいて新しい骨形成を刺激し、骨組織再生を促進することが実証される。
