Dietary emulsifier polysorbate-80 increases translocation of E coli across the intestinal epithelium. Polysorbate-80 increased translocation of Crohn's disease E coli across both (A) M-cells and (B) human follicle-associated epithelium (FAE). Similarly, polysorbate-80 enhanced translocation of E coli across (C) parent Caco2-cl1 cells and (D) human villus epithelium (VE). *, p<0.05; **, p<0.01; ANOVA (N=4–8). Crohn's E coli HM605 and EGFP-expressing HM615 were used for the in vitro and ex vivo epithelium translocation studies respectively.
