Figure 3From: Astragalus polysaccharide enhances immunity and inhibits H9N2 avian influenza virus in vitro and in vivoIllustrates real-time quantitative PCR analysis of major histocompatibility complexes (MHC) I, MHC II, and cytokines IL-2, IL-4, IL-10, IFN-γ, LITAF, IL-6, and IL-12 in Astragalus polysaccharide-treated chick embryo fibroblasts (CEF) infected with H9N2 AIV. IL-4 and IL-10 were expressed to high levels for CEF treated with 321.25μg/mL APS.Back to article page
