Research Overview
hBD-1
hBD-1 has been studied as part of the oral mucosal defense system and is linked to host resistance against dental pathogens. Research spans periodontitis, candidiasis, and epithelial barrier biology.
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.
