Trans-epithelial electric resistance (TEER) in the presence of compounds increasing Lucifer yellow (LY)-transport.

TEER was measured at the end of the experiment. Deviation (dev) is calculated as the absolute value of the difference between the two experiments divided by 2. The number n is the number of independent experiments and number m is the total number of wells analysed (observations). CpG ODN = short oligonucleotide rich in CG dinucleotide motifs. Control for Cytochalasin D (CytD)-treatment is with vehicle (DMSO).
