Administration of T. halophilus to DSS-induced colitis mice significantly decreased the frequencies of CD83+ cells compared to non-treated colitis mice in PBL (12.33 ± 2.11% vs. 39.88 ± 8.91%, p < 0.001) and in IELs (44.63 ± 14.81% vs. 67.92 ± 1.10%, p < 0.01), respectively (Figure 2B,F). The gene discussed is CD83; the disease is colitis.
