経歴
I was born in Fukuoka, Japan 1965, and studied medicine at Ryukyu University School of Medicine and finished Postgraduate course in Nagasaki University. Since 1995, I have studied about the most mysterious infectious agent, prion, in Japan, France, and US. From 2009, I am leading my prion research team as a professor in Nagasaki University Graduate School of Biomedical Sciences.
教育活動
Molecular medicine about prion diseases
研究活動
- Our studies focus on drug-discovery, developing a new diagnostic method for prion diseases, and analysis of host-pathogen relationship.
- Recently, we have developed a new in vitro amplifying method of PrPSc (real-time Quaking Induce Conversion: RT-QuIC). We applied this amplification technique to detect small amounts of PrPSc in patient’s samples and established as a diagnostic test of human prion diseases.

メッセージ
100%致死性の感染症で人類にとって最も悲惨な病とも言われるプリオン病を専門に研究しています。感染するたんぱく質,遺伝子のない病原体,うつる認知症,アミトイドーシス,人獣共通感染症,とプリオンはいろんな顔を持ち,遺伝性の病型も存在する。そのため分野横断的な研究アプローチが必要となる。BSE発生は食の安全に関わる問題であり,国際的な輸入規制問題に発展したことは覚えている人も多いかもしれません。授業では,プリオン病発見の歴史や病原体を同定するまでの道のりを学びながら,「感染するたんぱく質」の存在意味などを考え,みなさんとディスカッションをしていきたいと考えています。
