Effect of EPEC endotoxin and bifidobacteria on intestinal barrier function through modulation of toll-like receptor 2 and toll-like receptor 4 expression in intestinal epithelial cell-18

Figure 4 Changes in intestinal epithelial cell-18 cell membrane resistance after treatment with EPEC endotoxin and bifidobacteria for 16 h. The transepithelial electrical resistance in the B.infantis, B.longum, B.bifidum and B. youth groups decreased by only 19%, 18%, 23% and 23% respectively after 120 min of intervention,as compared with the control group. However, the transepithelial electrical resistance in the EPEC intervention group reduced significantly, by 67% compared to the normal control group (P < 0.05).
