| Outline of Final Research Achievements |
When ebolavirus enter host cells, ebolavirus glycoprotein (Ebo-GP) associates with host receptors. We identified a new entry receptor EGPR on the surface of host cells. We also found that glycans on Ebo-GP are required for the binding of EGPR to Ebo-GP. Furthermore, EGPR enhances the infectivity of all 5 subgenus of ebolavirus that are known to infect human. We also analyzed EGPIM expressed on the NK cells that attack and remove viruses in the host. We discovered that Ebo-GP inhibits the binding of EGPIM to the ligand, which suggests a mechanism that ebolavirus the evade from cytotoxicity by NK cells.
