West Nile virus envelope proteins: nucleotide sequence analysis of strains differing in mouse neuroinvasiveness.
1 Oct 1998
Abstract excerpt
Several neuroinvasive and non-neuroinvasive West Nile (WN) viruses were characterized by nucleotide sequencing of their envelope (E) protein regions. Prolonged passage in mosquito cells caused loss of neuroinvasiveness and acquisition of an N-linked glycosylation site, which is utilized. Limited passage in cell culture also caused glycosylation but not attenuation, suggesting that glycosylation may not be...
