In the two inflammatory bowel diseases, ulcerative colitis (UC) and Crohn’s disease (CD), altered expression of tight junction (TJ) proteins leads to an impaired epithelial barrier including increased uptake of luminal antigens supporting the inflammation. Here we focused on regulation of tricellulin, a protein of the tricellular TJ essential for the barrier against macromolecules, and hypothesized a role in paracellular antigen uptake. We report that tricellulin is downregulated in UC, but not in CD, and that its reduction increases the passage of macromolecules. Using a novel visualization method, passage sites were identified at TJ regions usually sealed by tricellulin. We show that interleukin-13 (IL-13), beyond its known effect on claudin-2, downregulates tricellulin expression. These two effects of IL-13 are regulated by different signaling pathways: The IL-13 receptor α1 upregulates claudin-2, while IL-13 receptor α2 downregulates tricellulin. We suggest to target the α2 receptor in future developments of therapeutical IL-13-based biologicals.
