Figure 5From: Transcellular transport of West Nile virus-like particles across human endothelial cells depends on residues 156 and 159 of envelope proteinEffect of double amino acid substitutions of E protein on the transport of VLPs. HUVEC were exposed to 6-LP, 6-LP S156P V159I, Eg P156 S I159V or Eg VLPs. After 24 h, media at the lower chamber were collected and subjected to IFU assay. * p < 0.01 (versus 6-LP). The graphs show the mean of three determinations. The error bars show SD. The results are representative of 2 independent experiments.Back to article page
