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.
Piscidin-3
Preclinical research indicates strong activity against bacterial membranes and drug-resistant strains. Analogs are being evaluated to balance potency with lower toxicity and better stability.
