Effects of probiotics on DC-induced expression of integrin β7 by T cells.

T cells in the MLR culture were identified by staining with anti-CD3. Data are mean ± SE for n = 8 samples from each group. Data were normalised by the Johnson Transformation. There was a significant effect of age (P < 0.05) and of treatment (P < 0.05) on expression of integrin β7 (two-way ANOVA). Significant differences are denoted as ^NP < 0.05 relative to the no-DC control for T cells within the same age group; ^DP < 0.05 relative to DC-stimulated T cells (without LPS/probiotics) within the same age group; ^TP < 0.05 relative to older T cell with the same treatment. Significant age-differences of DCs are donated as * P < 0.01 for the same treatment within the same age group of T cells (post hoc tests with Bonferroni correction).
