The lung cytokine gene expression profiles of mice infected with 2 strains of H4N8 viruses isolated from shorebirds and reference H4 viruses from ducks are compared. Major differences between the two H4N8 strains of shorebirds, one of which causes a severe respiratory disease in mice, are in the PB1 and NS1 genes. In mice with H4N8 virus induced pneumonia, overall expression of TNF-α, IL-6 and IL-12 genes was markedly higher than in mice infected with other H4 viruses tested, although gene expression of type I interferon was not increased until day 4 post viral infection. In contrast, in mice infected with a comparison H4N8 strain, gene expression of type I interferon peaked on day 1 post viral infection. Overall, the cytokine response corresponds with the... |
