Causal immune-inflammation mapping of the GERD-Barrett-adenocarcinoma cascade identifies FGF19-HLA-DR⁺ T-cell axis driving esophagogastric junction metaplasia.
BACKGROUND Gastroesophageal reflux disease (GERD), Barrett's esophagus (BE), and esophageal adenocarcinoma (EAC) form a recognized pathological continuum, but the causal immune and inflammatory processes driving progression remain incompletely defined. METHODS Summary-level genome-wide association study (GWAS) data w...
