Glycyrrhizin Exerts Antioxidative Effects in H5N1 Influenza A Virus-Infected Cells and Inhibits Virus Replication and Pro-Inflammatory Gene Expression
Figure 2
Influence of glycyrrhizin on H5N1-induced expression of CXCL10, IL6, and IL8 in A549 cells.
Excretion of cytokines by non-infected (Mock) A549 cells or A549 cells infected with different H5N1 strains at different MOIs 24 h post infection determined by ELISA. For each MOI five bars are presented. From the left to the right these bars represent: untreated virus control, glycyrrhizin 25 µg/ml, glycyrrhizin 50 µg/ml, glycyrrhizin 100 µg/ml, glycyrrhizin 200 µg/ml. * P<0.05 relative to non-treated virus control.
