(11)(a)標識化された上記(1)~(5)のいずれか記載のペプチドと、採取された生体試料とを接触させる工程;(b)前記標識を検出する工程;の(a)及び(b)を順次含むことを特徴とするアミロイド線維形成性ペプチドの検出方法。
AX1VX2IX3X4 (I)
(式I中、Aはアラニン、Vはバリン、Iはイソロイシン、X1、X2,X3は親水性アミノ酸を表し、X4はトレオニン又はバリンを表す)
で示されるアミノ酸配列を含むペプチド(以下、「本件ペプチド」ともいう)であればよいが、アミノ酸残基数としては8~18、好ましくは8、16又は18、より好ましくは8を挙げることができる。式(I)で示されるアミノ酸配列のN末端側及び/又はC末端側には、任意のアミノ酸残基が配置されてもよいが、式(I)のC末端には親水性アミノ酸残基が隣接することが好ましく、アスパラギン酸(D)、又はアルギニン(R)が隣接することがより好ましい。また、本件ポリペプチドのアミノ酸残基数が8を超える場合には、式IにおけるX4からC末端側の2番目又は3番目に位置するアミノ酸残基において、D体アラニンを配置することが好ましい。D体のアラニンを配置することで、D体のアラニンの位置で本件ペプチドを折りたたみ構造とすることが可能となる。
例示に限定されるものではない。
アミロイド線維が形成されるためには、図1Aに示すようにアミロイド性βシートの両側に疎水性残基の列が必須である。そこで、疎水性相互作用の促進を遮断するペプチドを設計すれば、アミロイド線維の形成が抑制できるという仮説を立てた。
後述の実施例で用いるアミロイド線維の形成抑制ペプチドとしてペプチドSBK(配列番号3)、ペプチドpm-strand-V(配列番号4)、ペプチドpm2h(配列番号5)、ペプチドbm1h(配列番号6)、ペプチドpm-strand-T(配列番号7)、及びアミロイド線維形成性ペプチドとしてペプチドBM1-24(配列番号8)、ペプチドPrion178-199(配列番号9)、ペプチドSAA1-27(配列番号10)、ペプチドPmel17(配列番号13)をFmoc固相合成法により合成した。反応に用いた樹脂はFmoc-NHCH2C6H2(OCH3)2-O-resinを用いた。カップリングはアミノ酸50 mmolをo-(ベンゾトリアゾール-1-イル)-N,N,N’,N’-テトラメチルウロニウムテトラフルオロボレート(TBTU)、1-ヒドロキシベンゾトリアゾール(HOBt)、N-メチルモルホリン(NMM)(各1:1:2当量)をN,N-ジメチルホルムアミド(DMF)溶液に溶かした液339 ml(カップリングあたり)を用い、30分反応させた。脱FmocはPIP-HOBt(30 %、2 %)のDMF溶液を用い7分間を2回行った。合成終了後、ペプチドが伸長生成しているレジン(resin)をDMF溶液で洗浄し、次にCH2Cl2で洗浄して減圧乾燥させた。解列反応はトリフルオロ酢酸(TFA) 86 %、エタンジオール(EDT) 6 %、トリイソプロピルシラン(TIPS) 6 %、H2O 2 %の割合で混合した液1500 mlを用いた。なお、後述の実施例1で用いるアルツハイマー型認知症原因ペプチドAβ1-40、アルツハイマー型認知症原因ペプチドAβ1-42は市販品(株式会社ペプチド研究所製)を用いた。
上記で合成したそれぞれのペプチドの分離精製はHPLCを用いて行った。装置は液体クロマトグラフィーシステム(SCL-10Avpコントローラ、SPD-10Avp UVモニター、LC-10Aiポンプ:日立ハイテクサイエンス社)を用いた。カラムは分取用としてShimPack-PREP-C8 (20.0x250 mm:島津ジーエルシー社製)を用いた。回収フラクションを凍結乾燥させて白色粉末状の目的ペプチドを得た。
上記で得られた白色粉末状のペプチドを0.1%トリフルオロ酢酸(TFA)水溶液に溶解した。この溶液をペプチド一次試料溶液(stock solution)とする。それぞれのペプチドのstock solutionから0.2mMとなるように一定量をとり出し、減圧乾燥後、50mMのCH3COONa-CH3COOH緩衝溶液(pH4.5)に溶解濃度0.2mMとなるように溶解させた。
0.1%TFA水溶液中のアミロイド線維形成性ペプチド(配列番号8記載のバルナーゼモジュール1のN末端1-24アミン酸残基:BM1-24、配列番号9記載のプリオン病原因タンパク質の178-199アミノ酸残基:Prion178-199、配列番号10記載の続発性アミロイドーシス原因タンパク質の1-27アミノ酸残基:SAA1-27、配列番号11記載のアルツハイマー型認知症原因ペプチド Aβ1-40、配列番号12記載のアルツハイマー型認知症原因ペプチドAβ1-42、配列番号13記載のPmel17)のstock solutionから溶解濃度0.2mMとなるように一定量をとり出し、減圧乾燥後、それぞれのアミロイド線維の形成抑制ペプチド添加ありの場合は、上記(3)で調製した水溶液を、添加なしの場合は緩衝液のみをそれぞれに250 μl加えた。すなわちモル比でアミロイド線維形成性ペプチド:アミロイド線維の形成抑制ペプチド=1:1になる。
チオフラビンT(ThT)色素を用いた結合試験は、アミロイド線維に特異的に結合し強い蛍光を発することで、アミロイド線維の形成の有無を評価できるアッセイである。ThT結合実験は蛍光分光光度計RF-5000の装置で測定を行った。上記(4)で調製したペプチド溶液から18 mlほどサンプリング後、測定濃度が2 mMになるように5 mM ThT水溶液を1782 ml すなわち1000倍希釈して蛍光スペクトルの測定を行った。
ThTの蛍光強度を1とした時の増大率 = ペプチド溶液の蛍光強度 / ThTのみの蛍光強度
で表した。ThTの蛍光強度を1とした時の増大率が2以上の増大が見られるとアミロイド線維を形成していると判断した。反対に2未満、好ましくは1.8未満の場合は、ThTのみの蛍光強度しか観測されていないため、アミロイド線維を形成していないと判断することができる。
上記(4)におけるペプチドSBK添加なしペプチドでアミロイド凝集体を確認後、この溶液9μlに、上記(3)のペプチドSBK溶液9μlを添加した。この混合液を測定濃度が2μMになるように5μM ThT水溶液を1782μl すなわち1000倍希釈し蛍光スペクトルの測定を行った。蛍光測定の条件は上記(5)と同じである。
