Research Overview
Trefoil factor 2
TFF2 strengthens mucus-barrier repair and epithelial restitution after gastric injury in experimental systems, making it a well-known gastric-protective peptide.
Secretin
Secretin is a classic GI hormone with extensive physiology literature and established diagnostic use. It remains important for studying pancreatic secretory function, biliary responses, and duodenal feedback.
