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.

Omentin-1

Lower omentin-1 levels are often associated with obesity, insulin resistance, and metabolic syndrome. Research continues on its use as a biomarker and as a mechanistic lead for AMPK-linked metabolic interventions.
