A)蒸留水希釈サンプル(サンプルA)
FM患者の血清及び健常人の血清を各々蒸留水で希釈し、遠心ろ過フィルターを用い高分子分子量物質(5,000Da以上)を限外ろ過により除去した後、逆相樹脂固定チップZiptip C18に吸着させ、50%アセトニトリル/0.1%TFAで溶出させてペプチド画分を回収し、マススペクトルの測定に用いた。尚、ペプチドの同定のためには、Ziptip C18に吸着させた後、10、20、30、40、50%アセトニトリル/0.1%TFAで段階的に溶出させたペプチド画分を用いた。
キャリア蛋白質に結合するペプチドの回収を高める目的で、FM患者の血清及び健常人の血清を各々10%アセトニトリルで希釈し、遠心ろ過フィルターを用い高分子分子量物質(5,000Da以上)を限外ろ過により除去した後、逆相樹脂固定チップZiptip C18に吸着させ、30%または60%のアセトニトリル/0.1%TFAで溶出させてペプチド画分を回収し、マススペクトルの測定及び同定に用いた。
上記(1)で得られたペプチド画分(サンプルA及びB)を各々マトリクス溶液(α-Cyano-4-Hydoroxycinnamic Acid)と混合し、ターゲットプレート上に塗布して、MALDI-TOF/MS (Ultraflex TOF/TOF、Bruker Daltonics社)を使用し、マススペクトル(測定範囲;サンプルA:m/z 800-3,500 サンプルB:m/z

同定されたペプチドシグナルについて、30%アセトニトリルによる溶出は表2に、また60%アセトニトリルによる溶出は表3に、これらの結果の一例を示す。
C3f由来のペプチドであるものが同定され、また、FM患者で発現量が有意に低いペプチドについては、fibrinopeptide A由来及びtransthyretin chain A由来のペプチドであるものが同定された。
これらの同定された蛋白質及びペプチドの生理機能等について以下に述べる。
Kininogenはヒトでは644アミノ酸からなる血漿蛋白質で、カルシウム結合、プロテアーゼ阻害、細胞接着抑制因子、抗血栓因子等の様々な生理機能を持っていることが知られている。また、kallikreinによってkininogenの第4ドメインからbradykininが産生され、発痛、血管拡張、血管透過性亢進、急性炎症症状等を引き起こすことが知られている。今回同定されたkininogen由来のペプチドはいずれも陰電荷表面との結合に重要な役割を果たす第5ドメインに含まれる配列で、ヒスチジンが多く非常に電荷に富み親水性を示すものである。
ITIH4はInter alpha inhibitor
familyに属する930アミノ酸からなる蛋白質で、外傷後などに血清で増加することが知られているが、プロテアーゼ阻害活性を持つbikunin chainを持っていない点で、このfamilyの他の分子とは異なっている。
Apolipoproteinsはlipoproteinsと結合し、lipoproteinsの認識や脂質代謝に関与する酵素群の活性化あるいは補酵素として働く一群の蛋白質である。構造や機能によりAからEまでの5種に大別され、さらにサブクラスに分けられる。ApoEは細胞にlipoproteinsが認識される際のマーカーとなる蛋白質であるが、近年痴呆との関連が研究されてきている。
今回FM患者血清における発現量が低いとして同定できたペプチドは、ほとんどがfibrinopeptide A由来の配列であった。fibrinopeptide Aは、血漿中に大量に存在する糖蛋白質fibrinogen alphaからトロンビンにより切断・産生される、血清中に比較的多量に存在するペプチドであり、凝固の促進開始期の指標として用いられている。
血液中の存在する補体系の蛋白質であるC3bから切り出されるペプチドフラグメントである。
FM患者で低値が認められたもう一つの蛋白質であるTTR
chain Aは、血液や脳脊髄液に存在し、甲状腺ホルモンやレチノール等のキャリア蛋白質と考えられている。家族性TTR関連アミロイドーシスでは、TTRの遺伝子変異が疾患に関与することや、老人性アミロイドーシスでは野生型TTRがアミロイドを構成する蛋白質となっていることが報告されている。アミロイドーシスでは症状として多発性ポリニューロパシー等の神経症状や手根管症候群等も観察されることから、FMと共通の機序の存在する可能性が考えられる。また、アミロイド沈着はリウマチ等の炎症疾患により続発性にも生じることから、炎症を含めた何らかの変化により、TTRの分解異常がFM患者で起きている可能性も考えられる。
