Effect of L. lactis NCDO 2118 on T cells and tolerogenic dendritic cells. The numbers of activated T cells, regulatory T cells and tolerogenic dendritic cells in chemically induced colitis were determined in the mesenteric lymph nodes (mLNs) and spleen; the cells were stained at day 21. (A) Number of CD4 + CD69+ T cells. (B) CD4 + CD25 + CD45RBlow T cells. (C) CD4 + CD25 + LAP + T cells. (D) CD11c + CD11b-CD103+ cells. Bars are the mean of 5 mice/group, and the data are representative of two independent experiments; ANOVA, Tukey post-test. **, p < 0.01, ***, p < 0.001.
