Concentrations of A occludin protein and B E-cadherin protein in Caco-2 cell lysates either untreated, treated with LPS (0.1 mg/ml) or treated with LPS and then incubated with viable cells (2 × 106 CFU/well) of L18 isolate was determined by indirect Enzyme Linked Immunosorbent Assay (ELISA). The experiment was performed in triplicate. Bars are representative of the means and error bars represent standard deviation. Significant differences between the L18-treated sample and the only LPS-treated control were measured by using unpaired Student’s t-test. *Significance at p values < 0.05
