Laboratory of Ultrastructural Virology

Research summary

Research outline

From ancient times to the present, we have always been threatened by various viruses. Our laboratory studies highly pathogenic human viruses such as influenza virus, Ebola virus, and SARS-CoV-2. Our goal is to understand the mechanisms of virus replication and pathogenesis at the molecular, cellular, organ, and individual levels. The strongest point of our laboratory is the use of state-of-the-art structural techniques such as cryo-electron microscopy, three-dimensional electron microscopy, high-speed atomic force microscopy, as well as conventional virological and molecular/cellular biological techniques.

Main themes

  • Mechanism of influenza virus replication
  • Structural analysis of Ebola virus
  • Studies on replication and pathogenesis of SARS-CoV-2
  • Structural analysis on virus neutralization by antibodies
  • Mechanism of arenavirus persistent infection
  • Identification of virus entry inhibitors for antiviral drug development
