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.
Plecanatide
Clinical trials show plecanatide improves constipation outcomes with a generally favorable tolerability profile. Like linaclotide, it acts locally in the intestinal lumen via GC-C signaling rather than systemic hormone effects.
