Research on coronaviruses

At the time of the COVID-19 (Severe Acute Respiratory Syndrome Coronavirus 2: SARS-CoV-2) outbreak and pandemic, we were responsible for the respiratory virus division (Department of Virology 3) at the National Institute of Infectious Diseases (NIID). We were deeply involved in the laboratory diagnosis of Japan's first case, the nationwide deployment of diagnostic methods, the establishment of virus isolation techniques, the distribution of VeroE6/TMPRSS2 cells to hundreds of domestic and international sites, and the development of therapeutic agents. After transferring to the University of Tokyo in September 2022, we have continued our research on coronaviruses.
