Changes in IL-4, IFN-γ, IL-10, TNF-α and IgE levels in serum from mice suffering from atopic dermatitis that were treated with ST-miRCCL22. Mice were orally infected with 1.6 × 108 c.f.u. ST-miRCCL22 and ST-miRCV. Total IL-4 (A), IFN-γ (B), IL-10 (C) and TNF-α (D) levels of ST-miRCCL22 treated mice were examined by ELISA. Total IgE levels in ST-miRCCL22-treated mice were lower when compared with the PBS or ST-miRCV groups (E). *P < 0.05 when comparing the ST-miRCCL22 group with the ST-miRCV-control group (n = 5). The results are expressed as the mean ± SEM (n = 5).
