Research Overview

Arenicin-1

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

TFF3

TFF3 is a well-established mucosal repair factor in the literature, especially in the context of intestinal injury and inflammation. Experimental studies support a role in accelerating restitution and protecting the epithelial surface in gut disease models.
