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.

Pleurocidin

Preclinical studies report membrane-active killing of bacteria and some activity against cancer cell lines. Multiple analogs have been developed to reduce toxicity while preserving potency.
