Research Overview
Exendin-4
Exendin-4 helped establish GLP-1 receptor biology in diabetes and remains a classic beta-cell protective peptide. Preclinical studies show reduced beta-cell apoptosis, improved insulin content, and better islet function under metabolic stress.
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.
