肠道外分泌谱系,包括杯状细胞和潘氏细胞,提供重要的先天宿主防御病原体。然而,这些细胞如何被指定和维持以确保肠屏障功能仍然不清楚。本研究表明,内质网膜蛋白复合物亚单位3 (Emc3)对外分泌谱系的分化和功能至关重要。肠上皮中Emc3的缺失减少了杯状细胞和Paneth细胞群的粘液产生,并导致肠道微生物生态失调,从而导致自发性炎症和对dss诱导的结肠炎的易感性增加。此外,Emc3缺失会损害Paneth细胞的干细胞生态位功能,从而导致肠道类器官培养失败。机制上,Emc3缺乏导致内质网(ER)应激增加。用牛磺酸去氧胆酸减轻内质网应激,缓解分泌功能障碍,恢复类器官形成。我们的研究确定了Emc3在维持肠黏膜稳态中的主导作用。
Intestinal exocrine secretory lineages, including goblet cells and Paneth cells, provide vital innate host defense to pathogens. However, how these cells are specified and maintained to ensure intestinal barrier function remains poorly defined. Here we show that endoplasmic reticulum membrane protein complex subunit 3 (Emc3) is essential for differentiation and function of exocrine secretory lineages. Deletion of Emc3 in intestinal epithelium decreases mucus production by goblet cells and Paneth cell population, along with gut microbial dysbiosis, which result in spontaneous inflammation and increased susceptibility to DSS-induced colitis. Moreover, Emc3 deletion impairs stem cell niche function of Paneth cells, thus resulting in intestinal organoid culture failure. Mechanistically, Emc3 deficiency leads to increased endoplasmic reticulum (ER) stress. Mitigating ER stress with tauroursodeoxycholate acid alleviates secretory dysfunction and restores organoid formation. Our study identifies a dominant role of Emc3 in maintaining intestinal mucosal homeostasis.
