Kisspeptin-10
Kisspeptin-10 is a decapeptide fragment of the larger kisspeptin protein, crucial for regulating the hypothalamic-pituitary-gonadal (HPG) axis and reproductive function. It acts as a potent stimulator of GnRH release.

Product Description
Kisspeptin-10 is a naturally occurring neuropeptide, specifically a C-terminal fragment of the kisspeptin protein, which is encoded by the KISS1 gene. This peptide plays a pivotal role in the neuroendocrine control of reproduction across various mammalian species. It exerts its effects by binding to the G protein-coupled receptor GPR54, also known as the kisspeptin receptor or KISS1R, primarily located on gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus. The activation of GPR54 by Kisspeptin-10 leads to the pulsatile release of GnRH, which subsequently stimulates the pituitary gland to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These gonadotropins are essential for gonadal steroidogenesis and gametogenesis, thereby regulating puberty onset, fertility, and overall reproductive health. Research indicates its involvement in both male and female reproductive processes.
Research Information
Research into Kisspeptin-10 has highlighted its critical role as a master regulator of the HPG axis. Studies have demonstrated that administration of Kisspeptin-10 can potently stimulate GnRH and subsequent LH/FSH release, making it a subject of interest for investigating reproductive disorders. For instance, preclinical studies have shown that Kisspeptin-10 can restore reproductive function in models of hypogonadotropic hypogonadism, by directly activating GnRH neurons. Further investigations explore its potential therapeutic applications in conditions such as infertility, delayed puberty, and polycystic ovary syndrome (PCOS), by modulating the pulsatile release of GnRH. The precise mechanisms involve complex intracellular signaling pathways following GPR54 activation, leading to increased neuronal excitability and GnRH secretion. Ongoing research also examines its interaction with other neuroendocrine systems and its potential influence on metabolic and behavioral aspects linked to reproduction.
