BXhVH5VL1 N297A及びBXhVH5VL1のインビトロ特性分析
THP−1細胞上の細胞FcRsへの結合の評価
ヒト急性単球性白血病細胞株THP1(ATCC)を、RPMI1640/GLUTAMAX(Invitrogen)+10%胎児ウシ血清(Invitrogen)+Pen/Strep内において培養し、2〜9×100,000cells/mLに維持した。
図10は、先行技術の開示(米国特許第5,624,821号、Winter)に基づいて予想されたように、変異アイソフォームBXhVH5VL1 N297Aは細胞Fc受容体に対する有意な結合能を有していなかった。
インビボ実験
本発明の抗体/誘導体をさらに評価するために行ったインビボ実験について以下に記載する。
神経成長因子(NGF)及びその受容体TrkAは、炎症性疼痛に特有な痛覚の重要な媒介物質である。
1.最初に、ラットの足への組替えヒト(rh)NGFの皮内注射が、痛覚過敏の標準的な侵害受容試験で測定される行動性感作を引き起こすか否かを調べた(Hargreaveの足裏試験)。次に、100gのマウスIgG、muMNACEP、ヒトIgG及びBXhVH5VL1 N297A抗体の皮内同時投与によってrhNGF誘発感作が影響を受けるか否かを調べた。マウスIgG1及びヒトIgG抗体を陰性対照として適当な投与量で使用した。
全てのラットに番号を付け、実験を開始する前の24〜48時間にわたって試験手順に慣れさせた。行動は痛覚過敏の尺度としての足裏試験に対する足引き戻し時間(足を引っ込めるまでの時間)で調べた。
プロトコル1:時点0での皮内注射による治療投与
プロトコル2:後足にrhNGFを注射する24時間前の1回の全身投与(腹腔内)による治療投与
薬物療法を行う前に、ベースライン足裏及びフォンフライ試験を行った。
NGF誘発痛覚過敏のモデルにおける皮内注射によるBXhVH5VL1 N297A(図11)及びmuMNACEP(図12)(並びに相対対照としてのmIgG1及びhIgG)の抗痛覚過敏有効性を比較した。
NGF誘発痛覚過敏のモデルにおける全身投与によるBXhVH5VL1 N297A、muMNACEP mIgG1及びhIgGの抗痛覚過敏有効性を比較した。
本発明の抗体/誘導体をさらに評価するために行った別のインビボ実験について以下に記載する。
抗体/誘導体をマウスに腹腔内前注射した。18時間後、5%ホルマリンを右の足蹠に注射した。なめ時間(負傷した足をなめた時間)を1時間まで測定した。
神経障害性異痛を引き起こすために、マウスの坐骨神経を外科的に絞扼した。その後、抗体/誘導体を投与し、対側肢と比較した場合の、外傷肢への局部的な機械的刺激に対する後退応答を測定した。
ラットの尾の付け根に完全フロイントアジュバントを皮内注射した。約3週間後、ラットは関節痛を特徴とする全身性多発関節炎を発症した。ラットに抗体/誘導体を投与し、関節を穏やかに動かした場合の発声強度を測定する発声検定によって鎮痛作用を評価した。
アカゲザルに抗体/誘導体を静脈内投与(前投与)した。翌日、アカゲザルの尾にカラゲナンを皮下注射した。熱刺激に対する引き戻し時間を測定した。
文脈によってその他の解釈がなされない限りにおいて、以下の全般的事項が適用される。
1)上述した参考文献の開示内容は、上記参照によって本願に援用するものとする。
2)「含む」という用語は非限定的であり、「有する」及び「からなる」を含む。従って、「含む」という用語は、記載された実体、ステップ、複数の実体又は複数のステップが含まれることを意味し、その他の実体、ステップ、複数の実体又は複数のステップが排除されることを意味するものではない。
