Research Overview

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.

Secretin

Secretin is a classic GI hormone with extensive physiology literature and established diagnostic use. It remains important for studying pancreatic secretory function, biliary responses, and duodenal feedback.
