Because viruses consist of the nucleic acid as their genetic materials and an outer shell of protein (capsids), they cannot reproduce by itself. Viruses are allowed to replicate by exploiting cell machinery in host cells. Ebolavirus (EBOV) and Epstein-Barr virus (EBV) both cause major infectious diseases in humans, such as Ebolavirus disease and EBV -associated malignancies, respectively. The long-term goal of our study is to provide insights into the molecular mechanisms of their pathogenesis in the aspect of host-virus interaction, which shall lead to the development of rational therapies and diagnosis for them.

Ongoing projects

  1. Characterization of the mechanism by which EBOV is internalized into host cells
  2. Characterization of the mechanism of EBOV virion formation
  3. Role of exosomes released from EBV-infected cells
  4. Molecular mechanism of cell-to-cell contact-mediated EBV transmission in epithelial cells
  5. Characterization of maturation of EBV virions
  6. Development of therapeutics and diagnosis for EBOV- and EBV-associated diseases

Red fluorescent dye-labeled Ebolavirus particle (red) were internalized into the cells expressing GFP-actin (green). Internalization of viral particles induced membrane raffling, which is known to be associated with macropinocytosis.

Labeled Ebolavirus particles (red) were internalized into the cells expressing GFP-SNX5, which allows to visualize macropinosomes (green). Internalized viral particles were co-localized with macropinosomes.
