dc.description.abstract | Previous studies have shown that West Nile (Sarafend) virus matured by budding at the plasma membrane, which differs from the usual intracellular maturation of other flaviviruses. The present study investigated the trafficking mechanism of the envelope (E) and capsid (C) proteins of West Nile (Sarafend) virus during the replication cycle. The use of time-based double-immunofluorescence labelling coupled with the Triton X-100 extraction procedure revealed that both the E and C proteins were transported from the perinuclear region towards the plasma membrane along the microtubules simultaneously. The strong association of these virus proteins with the microtubules was demonstrated further with Triton X-100 extraction procedure coupled with double immunogold-labelling. Extraction of infected cells with Triton X-100 in high salt also revealed that virus E proteins were associated with the microtubules via protein-protein interaction. The disruption of microtubules with vinblastine sulphate inhibited the trafficking of both the virus E and C proteins. Both virus structural proteins were observed to co-localise and retained within vinblastine sulphate-induced microtubulin paracrystals. Extracellularvirus production was also reduced drastically by vinblastine sulphate at non-cytotoxic concentration. Subsequent studies revealed that the transportation of virus E protein was associated with the microtubules-based motor protein, kinesin. © 2002 Wiley-Liss, Inc. | |
