研究の概要
高分子抗原およびペプチド抗原の高感度酵素免疫測定法や抗体の高感度検出法を開発し、その生理機能の解析や病態との関連さらに診断への応用を行っています。また最近では,糖尿病予防教室を主催し、非侵襲性試料中のバイオマーカーを基盤とした運動・栄養指導法の開発を行っています。
1）タンパク質やペプチドの超高感度免疫測定法の開発とそれを応用した臨床診断法の開発を行っています。新しい抗体の酵素標識法の開発や新しい測定システムを開発する事により、従来の測定法では検出されなかった超微量のタンパク質やペプチドの測定を可能としてきました。その結果、今まで複雑な過程を必要としていた微量抗原の直接測定が可能となり、広範な測定対象を可能としました。現在では、検出感度はzeptomole（1x10-21mol; 約600分子）に達しています。これらの高感度測定法により、尿中ヒト成長ホルモン(hGH)の直接の測定を可能とし、尿による小人症の診断を可能としました。また、血中hTSH、hLH測定により、バセドウ病、性的発達不足の診断を可能としました。さらに超高感度化することにより、RT-PCRによるHIV-1 RNA検出と同時期にp24抗原を検出する事が可能となり、早期診断に貢献しました。最近では、新しい活性ペプチド・アドレノメジュリンやPAMPさらにグレリンを抽出・濃縮操作なしに直接に、しかも活性基を含むインタクト・ペプチドとして初めて測定を可能とし、生理機能や病態の解析に寄与しています。最近では、より的確な心不全の診断法を目指し、ネイティブproBNPやNT-proBNPおよびBNPの高感度分別測定法の開発を行っています。
2）感染や自己免疫疾患の早期診断を目的として抗体の超高感度免疫測定法の開発も行っています。抗体の新しい測定システムを開発する事により、ウエスタンブロット法の1万倍高感度な抗体の検出が可能となりました。その結果、HIV-1 感染の早期診断（平均２週間）を可能としました。さらに抗HIV-1 抗体の超高感度測定法の開発により抗原やRNA検出以前に抗体を検出し、HIV-1 RNAより早期の感染診断の可能性を示しました。また、サイログロブリン自己抗体検出では、バセドウ病や橋本病ばかりでなく全ての健常人血中に自己抗体を検出し、自己免疫疾患の新しい考え方を提唱しました。さらに、ガンの早期診断を目的としてガン自己抗体の超高感度免疫測定法の開発を行っています。
最近では、１型糖尿病やSPIDDMを高精度かつ早期に検出するために、膵島関連自己抗体（インスリン自己抗体、GAD抗体、IA-2抗体等）を高感度に検出する検出法を開発しています。さらに、単独の抗体検出では見逃すことがあるため、新規の高感度マルチ抗体検出法（インスリン自己抗体、GAD抗体、IA-2の同時検出）を開発し、コホート試料を用い、検証しています；地域イノベーション戦略支援プログラム（国際競争力強化地域）「とくしま「健幸」イノベーション構想推進地域」；「膵β細胞をまもる研究：膵島関連自己抗体の高感度検出による膵障害機構の解析と判定への応用」。
3）糖尿病予備群を捕捉するための、非侵襲性試料（尿）中の糖尿病リスク・バイオマーカー（アディポネクチン、レジスチン、レプチン、遊離インスリン受容体、インスリン、TNF-αなど）の超高感度測定法を開発しました。そして、このバイオマーカーを指標とする生活改善指導を行い、糖尿病発症リスクからの回避のための「糖尿病予防教室」を主催しています。
4）糖尿病性腎症に焦点を絞り、尿中アディポネクチンの分子パターンを識別する検出法を開発し、早期腎障害の検出から重症化に至る過程の診断法を開発している；地域イノベーション戦略支援プログラム（国際競争力強化地域）「とくしま「健幸」イノベーション構想推進地域」。
