Department of Virology

Department of VirologyThis Department has been conducting basic and applied research on arthropod-borne viruses (arboviruses) such as Japanese encephalitis virus (JEV), dengue virus (DENV), Zika virus, Chikungunya virus (CHIKV) and severe fever with thrombocytopenia virus (SFTSV).

Molecular epidemiology of arboviruses

We isolate DENV, JEV and CHIKV in Asia and African regions and conduct molecular epidemiological analysis to clarify international and inter-continental movement of these viruses. We also analyze unique genome sequences that are relevant to pathogenicity.

Research on vaccine development using reverse genetics

We have developed DENV infectious clones and identified viral determinants by modifying various parts of the genes. We are currently developing genetically engineered viruses as candidates for live attenuated DENV vaccines by financial support of GHIT.

Research on the pathogenicity of arboviruses and evaluation of therapeutic compounds using animal model

We elucidate the mechanism of pathogenicity and infectivity of arboviruses, such as DENV and SFTSV by using a mouse model.

Development of rapid diagnostic assay for infectious diseases

Various rapid diagnostics are being developed for arboviruses using PCR, LAMP, LC/MS and Immuno-chromatographic technologies for the detection of viral genome, protein and specific antibodies.

Activities as a WHO Collaborating Center

he department is designated as a WHO Collaborating Center for Reference and Research on Tropical Viral Diseases since 1993 and currently our department has been re-designated as a center for Tropical and Emerging Virus Diseases. The center has been collaborating with WHO in training WHO fellows from many developing countries and has deployed experts as WHO short-term consultants.
