Besides, we found that DEGs in H1N1pdms infection were completely present in nonpandemic H1N1 infection at 3 dpi, while only ten distinct DEGs (AREG, CXCL13, GATM, GPR171, IFI35, IFI47, IFIT3, ORM1, RETNLA, and UBD) in H1N1pdm strains infection were identified in comparison with nonpandemic H1N1 at 5 dpi (Figures 8(a) and 8(b)), suggesting that H1N1pdm induces host distinct response in the later stage of infection. The gene discussed is IFI35; the disease is infection.
