ペプチド免疫原は、Keck施設(the Keck facility)(Yale University)において、p−メチル−ベンズヒドリルアミン樹脂上での固相技術によって、Biosearch SAM 2合成装置(Biosearch,Inc.,San Rafael,Ca.)を使用して合成された。これらのペプチドは、HFを用いて樹脂から切断され、次いで、エーテルおよび酢酸を用いて抽出され、その後凍結乾燥された。続いて、ペプチドは、0.78×30cmカラム上での逆相支持媒体(Delta−Bondapak)の使用を伴い、0.1% TFA中のアセトニトリルの0−66%直線状グラジエントを用いるHPLCによって精製された。
研究は、いくつかの脳領域および脊髄に神経原線維タングルを発生するトランスジェニック(Tg)JNPL3 P301Lマウスモデルにおいて実施された(Taconic,Germantown,NY)(Lewis et al.,「Neurofibrillary Tangles,Amyotrophy and Progressive Motor Disturbance in Mice Expressing Mutant(P301L)Tau Protein」,Nat Genet 25:402−405(2000)、これはその全体が参照により組み込まれる)。このモデルは、ADのために理想的ではないが、これは、タングルの発生の結果を研究するため、およびこれらの凝集物の生成を妨害し得る治療をスクリーニングするための優秀なモデルである。これらの動物の別の利点は、比較的初期の病理の発症である。ホモ接合性系統において、タウ病理に付随する行動の異常は、少なくとも3ヶ月まで初期に観察できるが、動物は、少なくとも8ヶ月齢まで比較的健常のままである。換言すれば、8ヶ月目において、動物は、治療の効果がモニターされることを可能にするために十分良好に移動し、それら自体で摂食し、そして行動学的な作業を実施できる。
Phos−タウペプチドは、Adju−Phosアジュバント(Brenntag Biosector,Denmark)と1mg/mLの濃度で混合され、この溶液は、投与の前に4℃で一晩回転され、リン酸アルミニウム粒子にペプチドが吸着することを可能にした。
マウスは研究の開始前(T0)、3回目の注射の1週間後、その後定期的に、そして屠殺の際(Tf)に採血された。ワクチンに対する抗体応答は、血漿の希釈により(他に示されない場合、1:200)、ELISAアッセイを使用して、以前に記載されたように決定され(Sigurdsson et al.,「Immunization with a Non−Toxic/Non−Fibrillar Amyloid−β Homologous Peptide Reduces Alzheimer's Disease Associated Pathology in Transgenic Mice」Am J Pathol.159:439−447(2001)and Sigurdsson et al.,「An Attenuated Immune Response is Sufficient to Enhance Cognition in an Alzheimer's Disease Mouse Model Immunized with Amyloid−beta Derivatives」J Neurosci.24:6277−6282(2004)、これらはそれらの全体が参照により組み込まれる)、ここで、免疫原はImmulon(登録商標)マイクロタイターウェル(Thermo Fischer Scientific,Waltham,MA,)にコートされた。検出のために、西洋ワサビペルオキシダーゼに連結されたヤギ抗マウスIgG(Pierce,Rockford,IL)または抗マウスIgM(Sigma,St.Louis,MO)が1:3000希釈で使用された。テトラメチルベンジジン(Pierce)が基質であった。
タウ病理の組織学的分析のために、マウスは、フェノバルビタールナトリウム(120 mg/kg,i.p.)で麻酔され、動脈を横切ってPBSで潅流され、そして以前に記載されたように脳が処理された(Sigurdsson et al.,「Immunization with a Non−Toxic/Non−Fibrillar Amyloid−β Homologous Peptide Reduces Alzheimer's Disease Associated Pathology in transgenic Mice」Am J Pathol 159:439−447(2001);Sigurdsson et al.,「An Attenuated Immune Response is Sufficient to Enhance Cognition in an Alzheimer's Disease Mouse Model Immunized with Amyloid−beta Derivatives」J Neurosci 24:6277−6282(2004);およびSigurdsson E.,「Histological Staining of Amyloid−beta in Mouse Brains」Methods Mol Biol 299:299−308(2005)これらはそれらの全体が参照により組み込まれる)。手短に述べると、右半球が、過ヨウ素酸−リジン−パラホルムアルデヒド(PLP)中で一晩浸漬固定され、一方、左半球は、タウタンパク質分析のために素早く凍結された。固定後、脳は、20% グリセロールおよび2% ジメチルスルホキシド(DMSO)を含有するリン酸緩衝液に移され、切片化するまで4℃で保存された。連続冠状脳切片(40μm)が切断され、10番目毎に、PHFタウタンパク質のC末端上の微小管結合反復の中に位置するリン酸化セリン396および404を認識するPHF1モノクローナル抗体で染色された(Otvos et al.,「Monoclonal Antibody PHF−1 Recognizes Tau Protein Phosphorylated at Serine Residues 396 and 404」J Neurosci Res 39:669−673(1994),これはその全体が参照により組み込まれる)。
タウ免疫治療がP301Lにおいて観察される加齢関連感覚運動異常を予防もしくは逆転するか否か、またはこれがhtau/PS1マウスにおいていかなる運動不全も引き起こすか否かを決定するために、免疫原性Tau 260−264[P−Ser262](配列番号3)またはTau 379−408[P−Ser396,404](配列番号82)を投与された動物が、以下に記載される種々の感覚運動試験および認知試験を使用して評価された。
脳組織は、0.1mM 2−(N−モルホリノ)エタン(ethano)スルホン酸、0.5mM MgSO4、1mM EGTA、2mM ジチオスレイトール、pH 6.8、0.75mM NaCl、2mM フェニルメチルスルホニルフルオリド、完全ミニプロテアーゼ阻害剤混合物(Complete mini protease inhibitor mixture)(10mLの水中に1タブレット;Roche)、およびホスファターゼ阻害剤(20mM NaFおよび0.5mM オルトバナジウム酸ナトリウム)を含む緩衝液中で均質化された。次いで、このホモジネートは、4℃で30分間遠心分離され(20,000×g)、可溶性細胞質画分(上清1)および不溶性画分(ペレット1)を分離する。このペレットは、プロテアーゼ阻害剤およびホスファターゼ阻害剤を有さないが、1%(v/v)Triton X−100および0.25%(w/v)デオキシ(desoxy)コール酸ナトリウムを含んだ同じ体積の緩衝液に再懸濁され、50,000で30分間超遠心分離を行って、不溶性画分として分析された、界面活性剤で抽出された上清2を得た。上清1および2は100℃で5分間加熱され、同じ量のタンパク質が12%(w/v)ポリアクリルアミドゲル上で電気泳動された。ブロットはTBS中0.1% Tween−20を有する5%ノンファットミルクでブロックされ、様々な抗体とともに一晩インキュベートされ、次いで、ペルオキシダーゼ結合体化抗マウスまたは抗ウサギIgGとともに室温で1時間インキュベートされた。続いて、結合した抗体は、ECL(Pierce)によって検出された。イムノブロットのデンシトメトリー分析は、NIH Image Jプログラムによって実施された。ある研究は、病理生理学的条件の変化および細胞外マトリックス成分との相互作用はアクチンタンパク質合成を変化し得、アクチンを内部標準として不適切にすると報告しているので、病理学的タウのレベルはアクチンレベルの代わりに全体のタウタンパク質の量と比較して正常化された。
受動免疫の実行可能性を決定するために、ホモ接合性P301Lマウスは、P301L(JNPL3)マウスモデルおよびADにおいてNFTおよび前タングルを認識するモノクローナルタウ抗体であるPHF1(Dr.Peter Daviesより恵与)を腹腔内(i.p.)注射された(Lewis et al,「Neurofibrillary Tangles,Amyotrophy and Progressive Motor Disturbance in Mice Expressing Mutant(P301L)Tau Protein」,Nat Genet 25:402−40522(2000),これはその全体が参照により組み込まれる)。このモノクローナル抗体は、タウのC末端におけるセリンアミノ酸404および396上でリン酸化されたタウを認識する(Greenberg et al.,「Hydrofluoric Acid−Treated Tau PHF Proteins Display the Same Biochemical Properties as Normal Tau」,J Biol Chem 267:564−569(1992)これはその全体が参照により組み込まれる)。従って、これは、1つの積極的な免疫アプローチの表現型のモノクローナル類似体である(Asuni et al.,「Immunotherapy Targeting Pathological Tau Conformers in a Tangle Mouse Model Reduces Brain Pathology with Associated Functional Improvements」,J Neurosci 27:9115−9129(2007),これはその全体が参照により組み込まれる)、PHF1抗体エピトープを含有するTau379−408[P−Ser396,404]である。
10匹のbalb/cマウスは、N末端に加えられたシステイン残基を介してKLHに連結されたTau386−408[P−Ser396,404](配列番号13)で免疫される。血漿の段階希釈によって検出されるように、免疫原のタウ部分に対して強力な抗体力価が生成された(図13A)。2匹のマウスが細胞融合のために選択され、最初のスクリーニングが、KLHなしの同免疫ペプチドを用いて実施された。二次スクリーニングが、同じペプチド、ならびにTau386−408[P−Ser396],Tau386−408[P−Ser404]、および非ホスホペプチドTau386−408(図13B)を用いて実施された。このスクリーニングに基づいて、クローンが最初および2回目のサブクローニングのために選択された。重要なことに、多数の強力にポジティブなクローンが同定され(>50)、そして、この領域の中でホスホ−エピトープを特異的に認識し、またはこの領域の中のリン酸化されていない部位に結合し、それによって、分子の同じ領域の中のホスホまたは非ホスホタウエピトープに結合する抗体の効力および安全性のプロフィールの比較を可能にする、安定なクローンが同定された。
