Effects of administration of three types of bacterial strains on the large intestinal LP (LILP) T cells.

<p>Frequency of CD25+ FoxP3+ regulatory T cells (A), CD25+ FoxP3- effector CD4 T cells (B), ratio of regulatory T/effector T cells (C), CD69+ CD4 T cells (D), or CD69+ CD8 T cells (E) in the LILP following treatment with culture medium (white bars) (N = 6), <i>L. lactis</i> MG1363 (dashed bars) (N = 6), <i>L. plantarum</i> WCFS1 (grey bars) (N = 6), or <i>L. salivarius</i> 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.
