PS-F2 administration suppresses OVA-induced Th2 cytokine production. Mice were immunized, treated, and challenged as described in Figure 1. On day 28, BALF was collected, and levels of IL-4 (A), IL-5 (B), and IL-13 (C) were determined by ELISA (n = 10). Data shown are representative of 2 experiments. * P < 0.05, ** P < 0.01.
