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.


Molecular medicine about prion diseases


  • 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.

I specialize in prion disease, a 100% fatal infectious disease, which is said to be the most miserable disease for humankind. Prion encompasses various aspects including infectious protein, pathogens without genes, contagious dementia, amyloidosis, and zoonosis, which require cross-sectoral research approaches. The development of BSE relates to the problems of food safety, and many people may still remember this disease causing international issues in terms of import control. In the lectures, I plan to examine the meaning of the existence of “infectious protein” in pathogenic microorganisms through discussion, while learning the history of prion discovery and identification of the pathogen.
