在溃疡性结肠炎(UC)和克罗恩病(CD)这两种炎症性肠病中,紧密连接(TJ)蛋白的表达改变会导致上皮屏障受损,包括支持炎症的管腔抗原的摄取增加。在这里,我们重点关注三细胞蛋白(三细胞 TJ 中的一种蛋白质,对于大分子屏障至关重要)的调节,并假设其在细胞旁抗原摄取中的作用。我们报告说,三纤维素蛋白在 UC 中下调,但在 CD 中则不然,并且其减少会增加大分子的通过。使用一种新颖的可视化方法,在通常由三纤维素胶封闭的 TJ 区域鉴定了通道位点。我们发现,除了已知的 Claudin-2 作用外,白细胞介素 13 (IL-13) 还能下调三纤维素蛋白的表达。 IL-13 的这两种作用由不同的信号通路调节:IL-13 受体 α1 上调claudin-2,而IL-13 受体α2 下调三纤维素。我们建议在未来开发基于 IL-13 的治疗性生物制品时以 α2 受体为目标。
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.
