Research Overview
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.
Histatin-5
Histatin-5 is a major salivary defense peptide that can kill Candida species and influence oral microbial communities. It is also investigated for wound-healing and xerostomia-associated oral infection models.
