Effect of the secreted fractions (COF-SN and OMVs) from EcN and ECOR63 on the expression of TJ proteins in T-84 monolayers infected with EPEC. Intestinal epithelial cells were incubated for 3 h with EPEC at a MOI of 100 (black bars). Parallel infections were carried out in the presence of COF-SN (0.5 mg/ml) or OMVs (0.1 mg/ml) from EcN (white bars) or ECOR63 (gray bars). The relative mRNA levels of the indicated proteins were measured by RT-qPCR using β-actin as the reference gene. Data are presented as fold-change compared to untreated control cells (dotted line) from three independent biological experiments. a, Significance against untreated control cells (p ≤ 0.05); b, significance against EPEC-infected control cells (p ≤ 0.04)
