Ebola virus
Recently, TIM-1 has been shown to be a receptor or cofactor for Ebola virus entry. TIM-1 binds to Ebola virus glycoproteins (GP) and mediates Ebola virus cellular entry by increasing Ebola virus infectivity in cell lines with a low susceptibility. Moreover, reducing expression of endogenous TIM-1 in highly permissive cell lines decreased Ebola virus infectivity. Furthermore, TIM-1 IgV domain specific antibody ARD5 inhibited Ebola virus infectivity, indicating that TIM-1 was critical for Ebola virus entry. Also, TIM-1 expression on human mucosal epithelial cells from the trachea, cornea and conjunctiva demonstrated the correlation of TIM-1 expression feature and viral entry routes.
