Antiviral and Antioxidant Activity of a Hydroalcoholic Extract from Humulus lupulus L.

Figure 6

GSH levels measured in A549 cell lysates infected with PR8 or pH1N1 virus and treated with 140 μg/ml HOP extract after the adsorption (postinfection: p.i.) or before, during, and after the infection (b.d.p.i.). Levels are expressed as percentage of nmol/mg proteins (where levels from control cells were considered 100%). Data are mean ± SD from three independent biological replicates (). and versus infected cells by Student’s -test.
