Basic Medical Sciences

Infectious Diseases and Host Defense

We are studying Virology and Parasitology and Immunology. In Virology, our research focuses on coronaviruses and studies the molecular biology and host cell-virus interaction of these coronaviruses. We also establish reverse genetics methods for coronaviruses and will extend our project to eradication of Infectious diseases. In Parasitology and immunology, we are focusing about a host-parasite interaction, especially about the protective immune response against malaria parasites and about allergy, autoimmunity, and anti-tumor immunity upon parasite infection.

Research & Education

Business education

We are in charge of giving lectures for undergraduate and graduate students. In relation to our research, as one of the pathogens and their pathogenesis are lectured in the systematized VIROLOGY and PARASITOLOGY lectures. We also give lectures host defense mechanisms against pathogens as IMMUNOLOGY, and both for the third grade undergraduate students. For graduate school students, we instruct how to conduct scientific experiments to encourage their research mind.

Citizenship Activities

We instruct general information of malaria and parasitic diseases to the medical officers of Ministry of Foreign Affairs and to medical experts from developing countries. Among our social contributions we devote to grow up young researchers from Thai, Uganda, India, Bangladesh and so on. Furthermore, we transfer our discovery concerning drugs and vaccines against protozoa or parasites to licensing or getting patents.
