Kisspeptin-10

Overview

Kisspeptin is a family of neuropeptides encoded by the KISS1 gene that bind to the GPR54 receptor (KISS1R) and are now recognized as master regulators of the hypothalamic-pituitary-gonadal (HPG) axis. The discovery of kisspeptin's role in reproduction transformed understanding of how the hypothalamus initiates and maintains gonadotropin secretion. KP-10 is the minimal 10-amino acid fragment that retains full GPR54 binding and biological activity.

Clinical research has explored kisspeptin-10 infusions for diagnosing and potentially treating disorders of puberty, hypothalamic amenorrhea, and male infertility. It causes robust GnRH → LH → testosterone/estrogen pulses in human volunteers when administered acutely. Its role in integrating metabolic signals (energy status, stress) with reproductive function also makes it relevant to research on fertility under caloric restriction or exercise stress.

Mechanism of Action

Kisspeptin-10 binds GPR54 (KISS1R) on GnRH neurons in the arcuate and anteroventral periventricular nuclei of the hypothalamus, triggering phospholipase C activation and intracellular calcium release. This stimulates GnRH pulse release, which in turn drives pituitary LH and FSH secretion, activating gonadal steroidogenesis and gametogenesis.
