Effects of three bacterial strains on Peyer’s Patch T cells.
Frequency of CD69+ CD4 T cells (A), regulatory T/effector T cell ratio (B), CD25+ FoxP3- effector CD4 T cells (C), CD25+ FoxP3+ regulatory T cells (D), or CD69+ CD8 T cells (E) in the Peyer’s Patches following treatment with culture medium (white bars) (N=6), L. lactis MG1363 (dashed bars) (N=6), L. plantarum WCFS1 (grey bars) (N=6), or L. salivarius UCC118 (black bars) (N=6). Results are expressed as the mean ± standard error of the mean (SEM). Statistical significance was calculated using the Students t-test. * represents P-values <0.05.
