Multi-omics analysis identifies gut microbiota-glutamine axis contributing to the pathogenesis of reflux esophagitis
Qi Zhang
BackgroundReflux esophagitis (RE), a common gastroesophageal reflux disease characterized by esophageal mucosal inflammation, is closely associated with gut microbiota dysbiosis and metabolic abnormalities. The glutamine-glutamate metabolic pathway regulates inflammation and mucosal barrier function, but its role in RE and association with gut microbiota remain unclear. This study aimed to characterize gut microbiota and serum metabolites in RE patients via integrated multi-omics (focusing on th
