Cytokine production in the BAL fluid and spleen after pMG-Ag85B immunization. Mice were sensitized with OVA 3 times, and administered with pMG-Ag85B plasmid DNA, and then challenged with OVA. BAL fluid and spleens were harvested 24 hours after the last OVA challenge. IL-4 (A) and IFN-γ (C) levels in the BAL fluid were measured directly. Splenocytes were cultured and IL-4 (B) and IFN-γ (D) in the culture supernatant were measured 96 hours after incubation. Results are expressed as means ± SD for seven animals. *P < 0.05, **P < 0.01, for the pMG-Ag85B group versus the OVA-sensitized control group; +P < 0.05, ++P < 0.01, for the pMG-Ag85B group versus the pMG group.
