Concerted changes in the pediatric single-cell intestinal ecosystem before and after anti-TNF blockade
· 2026-09-01 · 原文
Crohn’s disease is an inflammatory bowel disease (IBD) commonly treated through anti-TNF blockade. However, most patients still relapse and inevitably progress. Comprehensive single-cell RNA-sequencing (scRNA-seq) atlases have largely sampled patients with established treatment-refractory IBD, limiting our understanding of which cell types, subsets, and states at diagnosis anticipate disease severity and response to treatment. Here, through combining clinical, flow cytometry, histology, and scRNA-seq methods, we profile diagnostic human biopsies from the terminal ileum of treatment-naive pediatric patients with Crohn’s disease (pediCD; n = 14), matched repeat biopsies (pediCD-treated; n = 8) and from non-inflamed pediatric controls with functional gastrointestinal disorders (FGIDs; n = 13)
