  • 1-a Values for transepithelial electrical resistance (TEER, Ω cm2) are given as the mean of four independent experiments.

  • 1-b Changes in TEER values on bacterial stimulation of CaCO-2 cells are given relative to control values (% of no treatment).

  • Time (0, 24 hours) is after bacterial stimulation of CaCO-2 cells.

  • PBMC, peripheral blood mononuclear cells.
