Abstract
Mononegaviruses are non-segmented negative-strand RNA viruses, and include measles, mumps, Marburg, and Ebola viruses. Measles virus and mumps virus, members of the family Paramyxoviridae, are immunotropic and neurotropic, respectively. Marburg virus and Ebola virus, members of the family Filoviridae, cause highly lethal hemorrhagic fever. In this paper, I summarize the recent structural and functional studies on the viral glycoproteins (GPs) of these viruses, which have shed light on virus entry and the humoral response. The structural and functional analyses of the interaction between viral GPs and receptors/antibodies also illuminate directions toward therapeutics against the viruses.
