Suppression of H5N1 in vitro replication in the presence of rAd(HA-1405). (a) Expression of HA in adenovirus-treated Vero cells was determined by western blot 24 hours post H5N1 challenge in comparison to β-actin. Cells pretreated with rAd-empty served as controls. (b–e) Plaque reduction assay was conducted in MDCK cells. Cells were preincubated with 10-fold serially diluted rAd(HA-1405) (ranging from 1010 to 108 vp) or rAd-empty (1010 vp). Twenty-four hours after treatment, 40–60 PFU of clade (b) 2.3.2, (c) clade 2.3.4, (d) clade 7, or (e) clade 9 H5N1 viruses were added to each well. The yields of viral progeny were determined by plaque assay. Data were shown as mean plaque counts ± SD from three independent experiments. ANOVA followed by Dunnett's test was used to compare the differences among different doses of rAs(HA-1405) groups and control group (PC). ** indicates P value was less than 0.01 in comparison to PC.
