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.
