Colitis, is a chronic immune-mediated gastrointestinal disorder with unclear etiology. Current therapies often fail to achieve complete remission, making it necessary to explore novel therapeutic strategies. The hygiene hypothesis suggests that helminth infections may modulate immune responses, offering potential benefits for inflammatory diseases. Nippotrongylus brasiliensis (Nb), a hookworm-like nematode, secrets immunoregulatory molecules, including uridine, which exhibits anti-inflammatory properties. Here, we investigated the protective effects of Nb infection, its excretory-secretory (ES) products, and uridine in a TNBS-induced IBD mouse model. Moreover, we conducted an RNA sequencing (RNA-Seq) analysis to elucidate the possible functional mechanisms for the protective effects of ES or uridine. Results demonstrated that uridine can exhibit a protective effect on TNBS-induced IBD in mice. RNA-Seq revealed that uridine upregulated slc10a2, encoding the apical sodium-dependent bile acid transporter (ASBT). By pharmacological inhibition of the encoding protein (ASBT), its impact on the protective efficacy has been abolished.Our findings demonstrate that uridine alleviates IBD by modulating ASBT, suggesting a novel therapeutic target for IBD intervention.
