The measurement of the transendothelial electrical resistance (TEER) showed that the SEPEC cytotoxic factor, which caused elongation and loss of intercellular junctions in HUVEC, also increased the cell monolayer permeability by ~46% within 30 min.
hDlg, a cytoplasmic protein of the MAGUK (Membrane-associated guanylate kinases) homologue family, is localized adjacent to intercellular junctions, where its interaction with E-cadherin in confluent epithelial cells has been demonstrated.
In pemphigus vulgaris cases, the immunoreactivity for IgG4 was most condensed to the intercellular junctions of suprabasal keratinocytes, consistent with the known location of desmoglein 3 (Figure 1, A).
The presence of intercellular junctions between the cells, showing a bigger adherence among these cells, also indicates the efficiency of the epidermal layer defense against possible water microorganism attacks, such as fungus, bacteria and protozoan, avoiding, therefore, infective biotic processes.
Numerous studies have shown that the intercellular junctions and, in particular, the tight junctions regulate the permeability of the paracellular spaces and limit "water leakage.
On observation with optical microscopy, we detected a dense structure of the CL tissue with more adherent intercellular junctions in the middle stages than in the early and late stages.

The binding of chitosan residues with sialic acid residues make prolonged contact of the drug with the epithelium, also it was assumed that opening of the intercellular junctions by chitosan could lead to the enhancement of peptide absorption across the mucosa.
