Crystal structure of the West Nile virus envelope glycoprotein.
The envelope glycoprotein (E) of West Nile virus (WNV) undergoes a conformational rearrangement triggered by low pH that results in a class II fusion event required for viral entry. Herein we present the 3.0-A crystal structure of the ectodomain of WNV E, which reveals insights into the flavivirus life cycle. We found that WNV E adopts a three-domain architecture that is shared by the E protein...
متن کاملStructure of West Nile virus.
West Nile virus (WNV) is found throughout Africa, Europe, Central Asia, and, most recently, in North America. The first outbreak in the United States was in New York City during the summer of 1999, and the virus subsequently spread across the United States (1). In 2002, there were 4156 reported cases of human illness associated with WNV and 284 deaths. WNV is a flavivirus transmitted primarily ...
متن کاملMeasles vaccine expressing the secreted form of West Nile virus envelope glycoprotein induces protective immunity in squirrel monkeys, a new model of West Nile virus infection.
West Nile virus (WNV) is a mosquito-borne flavivirus that emerged in North America and caused numerous cases of human encephalitis, thus urging the development of a vaccine. We previously demonstrated the efficacy of a recombinant measles vaccine (MV) expressing the secreted form of the envelope glycoprotein from WNV to prevent WNV encephalitis in mice. In the present study, we investigated the...
متن کاملAntiviral peptides targeting the west nile virus envelope protein.
West Nile virus (WNV) can cause fatal murine and human encephalitis. The viral envelope protein interacts with host cells. A murine brain cDNA phage display library was therefore probed with WNV envelope protein, resulting in the identification of several adherent peptides. Of these, peptide 1 prevented WNV infection in vitro with a 50% inhibition concentration of 67 muM and also inhibited infe...
متن کاملCrystal structure of the RNA polymerase domain of the West Nile virus non-structural protein 5.
Viruses of the family Flaviviridae are important human and animal pathogens. Among them, the Flaviviruses dengue (DENV) and West Nile (WNV) cause regular outbreaks with fatal outcomes. The RNA-dependent RNA polymerase (RdRp) activity of the non-structural protein 5 (NS5) is a key activity for viral RNA replication. In this study, crystal structures of enzymatically active and inactive WNV RdRp ...
