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.
Macimorelin
Macimorelin has been validated in clinical testing as an oral alternative to injectable GH stimulation tests. Its short-term use makes it a useful translational tool for evaluating pituitary GH reserve.
