Figure 1From: Transcellular transport of West Nile virus-like particles across human endothelial cells depends on residues 156 and 159 of envelope proteinTransport of 6-LP and Eg VLPs across a monolayer of HUVEC. HUVEC were exposed to VLPs for 0, 8 or 24 h. The numbers of transferred VLPs were determined by IFU assay. Gray bars, 6-LP VLPs. White bars, Eg VLPs. The graphs show the mean of three determinations. The error bars show SD. The results are representative of 2 independent experiments. *p < 0.01.Back to article page
