Description Pediatric-onset colitis and inflammatory bowel disease (IBD) have significant impacts on the growth of infants and children, but the etiopathogenesis underlying disease subtypes remains incompletely understood. Here, we report single-cell clustering, immune phenotyping, and risk gene analysis for children with undifferentiated colitis, Crohn's disease and ulcerative colitis. We not only demonstrated characteristics that was disease-specific, but also pathogenesis that was common and underpinned by the impaired cAMP-response pathway. Specifically, we showed that infiltration of PDE4B- and TNF-expressing macrophages, decreased abundance of CD39-expressing intraepithelial T cells, and platelet aggregation and release of 5-hydroxytryptamine at the colonic mucosae were common in colitis and IBD patients in comparison with control subjects. Targeting these pathways using the phosphodiesterase inhibitor dipyridamole restored immune homeostasis and improved clinical symptoms for children with colitis. In summary, comprehensive analysis of the colonic mucosae has uncovered common pathogenesis and a novel treatment for children with colitis and IBD.
