Research Overview
GLP-1
Native GLP-1 has a very short half-life because of rapid DPP-4 cleavage, so it is mainly used as a mechanistic research peptide. Across animal and cellular studies it reduces beta-cell apoptosis, improves insulin gene expression, and enhances islet resilience.
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.
