  • Department of Protozoology, Institute of Tropical Medicine (NEKKEN), Nagasaki University, Japan.


  • I graduated from Osaka City University Medical School, Japan in 1990 and then trained as an Orthopedic Surgeon for 2 years. Following that, I decided to spend 4 years studying malaria in Osaka City University’s Graduate School of Medicine. After I received my PhD, I worked in the Laboratory of Parasitic Diseases (Louis H. Miller Lab), NIAID, NIH, USA from 1997 to 1999. In 2000, I became a faculty member in the Department of Molecular Parasitology (Prof. Motomi Torii Lab), Ehime University School of Medicine, Japan and joined the Institute of Tropical Medicine, Nagasaki University as a full time professor in 2007. I was inspired to study malaria by the Prof. Kazuyuki Tanabe’s lecture in 1986. For more details, please read my memoir of Kazuyuki Tanabe published in Paraisotl Int (2014).

  • Malaria is a huge burden and responsible for many deaths in large areas of the tropical and sub-tropical world. In order to design and implement effective disease intervention strategies, I believe that one of the key priorities in malaria research should be the strengthening of our understanding of the basic biology of the parasite. My team is currently investigating some fundamental aspects of the parasite’s life cycle, such as the mechanisms behind red blood cell (RBC) invasion and the phenomenon of cytoadherence of parasite-infected RBCs using human malaria parasite Plasmodium falciparum, monkey malaria parasite P. knowlesi and rodent malaria parasite P. yoelii. I am also engaged in the field studies conducted in Thailand to understand the P. vivax biology in collaboration with Dr. Jetsumon Sattabongkot (Mahidol Vivax Research Center, Faculty of Tropical Medicine, Mahidol University, Thailand) and molecular epidemiology of P. falciparum in Kenya in collaboration with Prof. Akira Kaneko (Department of Parasitology, Osaka City University, Japan).kaneko_osamu_document01RBC invasion by P. yoelii.

When I was a medical student, I visited many tropical and subtropical countries and recognized that infectious diseases were still huge burdens in the world. Then, one day in a parasitology class, I learned that the disease malaria was a major problem, and thereafter I was fascinated by malaria and its causative pathogen, Plasmodium. Now I am conducting research to elucidate the molecular mechanism of host cell invasion and modification mechanisms by this parasite, toward finding weak points to combat the disease malaria.
