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.
Kisspeptin-52
Human and animal studies show kisspeptin-52 can acutely increase gonadotropin secretion and activate the hypothalamic-pituitary-gonadal axis. It has been explored in fertility research and assisted-reproduction settings as a way to trigger endogenous reproductive hormone release.
