Figure 17: Effect of fisetin and MCN-fisetin on the concentrations of cytokines IL-2, IL-4, IL-5, IFN-γ and TNF-α (in pg/ml), in BAL fluid. This assay was done using the BD CBA Mouse Th1/Th2 Cytokine Kit, in which five bead populations, coated with specific antibodies, are mixed to form a bead array, and resolved in a flow cytometer.
