Exogenous pathogenic bacteria exacerbated intestinal tract damage.
(n = 8). (a) H&E sections and representative images of morphological structures of intestine. Left: 40× magnification, right: insets depicting the intestinal tract at 200× magnification. (b) The ratio of γδ T, DC, NKT and NK cells in the intestine was detected by flow cytometric analysis. (c) ELISA measurement of TNF-α, IL-12 and IL-4 levels. (d) Lymphocytes were isolated from PPs. The percentages of DCs, T and CD44+ T cells were assessed after pathogenic bacteria with ConA administration. Data presented are the means ± SD. *P < 0.05, **P < 0.01, ***p < 0.001, one-way ANOVA.
