Abstract
V originále
IL-17 protects epithelial barriers by inducing the secretion of antimicrobial peptides (AMPs). However, the effect of IL-17 on Paneth cells (PCs), the major producers of AMPs in the small intestine, is unclear. Here, we show that targeted ablation of the IL-17 receptor (IL-17R) in PCs disrupts their antimicrobial functions and decreases the frequency of ileal PCs. These changes become more pronounced after colonization with IL-17 inducing segmented filamentous bacteria (SFB). Mice with PCs that lack IL-17R show an increased inflammatory transcriptional profile in the ileum along with the severity of experimentally induced ileitis. These changes are associated with a decrease in the diversity of gut microbiota that induces a severe ileum pathology upon transfer to genetically susceptible mice which can be prevented by the systemic administration of IL–17a/f in microbiota recipients. In an exploratory analysis of a small cohort of pediatric patients with Crohn’s disease, we have found that a portion of these patients exhibit a low number of lysozyme-expressing ileal PCs and a high ileitis severity score, resembling the phenotype of mice with IL-17R-deficient PCs. Our study identifies IL–17R-dependent signaling in PCs as an important mechanism that maintains ileal homeostasis through the prevention of dysbiosis.
