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.

hBD-1

hBD-1 has been studied as part of the oral mucosal defense system and is linked to host resistance against dental pathogens. Research spans periodontitis, candidiasis, and epithelial barrier biology.
