Research Overview

Arenicin-1

Marine annelid peptide with strong preclinical antibacterial activity and a stable structural motif that is useful for peptide engineering.

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.
