Abstract

Intestinal epithelial barrier dysfunction is a risk factor in the pathogenesis of Crohn's disease (CD); however, no corrective FDA-approved therapies exist. We used an enteroid (EnO)-based system in two murine models of experimental CD, SAMP1/YitFc (SAMP) and TNF (TNF). While severely inflamed SAMP mice do not generate EnOs, "inflammation-free" SAMP mice form EnO structures with impaired morphology and reduced intestinal stem cell (ISC) and Paneth cell viability. We validated these findings in TNF mice concluding that inflammation in intestinal tissues impedes EnO generation and suppressing inflammation by steroid administration partially rescues impaired formation in SAMP mice. We generated the first high-resolution transcriptional profile of the SAMP ISC niche demonstrating that alterations in multiple key pathways contribute to niche defect and targeting them may partially rescue the phenotype. Furthermore, we correlated the defects in formation and the rescue of EnO formation to reduced viability of ISCs and Paneth cells.

摘要

肠上皮屏障功能障碍是克罗恩病(CD)发病机制的一个风险因素;然而,目前还没有获得 FDA 批准的纠正疗法。我们在两种实验性 CD 的鼠模型(SAMP1/YitFc[SAMP]和 TNF)中使用类器官(EnO)为基础的系统。虽然严重炎症的 SAMP 小鼠不能产生 EnO,但“无炎症”的 SAMP 小鼠形成的 EnO 结构形态受损,肠干细胞(ISC)和潘氏细胞活力降低。我们在 TNF 小鼠中验证了这些发现,结论是肠道组织中的炎症阻碍了 EnO 的生成,通过类固醇给药抑制炎症可以部分挽救 SAMP 小鼠中受损的形成。我们生成了 SAMP ISC 生态位的首个高分辨率转录谱,表明多个关键途径的改变导致生态位缺陷,针对这些途径可能部分挽救表型。此外,我们将 EnO 形成的缺陷及其挽救与 ISC 和潘氏细胞活力降低相关联。
