We investigated the inhibitory effects of oral administration of Tetragenococcus halophilus MN45 (MN45) isolated from miso on the development of atopic dermatitis (AD) using NC/Nga AD model mice. NC/Nga mice were fed a diet containing 0.05% or 0.5% MN45 (0.05% or 0.5% MN45 groups) or lacking MN45 (control group). Mice were sensitized and boosted with picryl chloride by topical application once per week. IgE production in serum, clinical score and ear thickness in both MN45 groups were significantly suppressed. In addition, IgE and IL-17 production from splenocytes from mice in both MN45 groups were significantly decreased. IL-4 production from splenocytes in the 0.5% MN45 group decreased significantly, while IL-10 production from splenocytes in the 0.05% MN45 group increased significantly. These results demonstrate that intake of MN45 is effective in preventing and alleviating the development of type-1 allergic symptoms in humans.
