What is the Origin of Kisspeptin-10 Endogenous Regulation?

The concept is derived from neuroendocrinology, following the discovery of the Kisspeptin-GPR54 signaling system as the critical upstream regulator of Gonadotropin-Releasing Hormone (GnRH) secretion. The term "endogenous regulation" emphasizes the complex, natural feedback mechanisms that govern this system from within the brain. Dysregulation of Kisspeptin signaling is implicated in various reproductive disorders, including hypothalamic amenorrhea.

What is the Mechanism of Kisspeptin-10 Endogenous Regulation?

Kisspeptin-10 neurons project directly to GnRH neurons in the hypothalamus and act on the GPR54 receptor to trigger the pulsatile release of GnRH. This pulsatile GnRH, in turn, stimulates the anterior pituitary to release Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), which then drive gonadal sex hormone production. The regulation is tightly controlled by sex steroid negative feedback, ensuring appropriate and rhythmic reproductive hormone homeostasis.

Kisspeptin-10 Endogenous Regulation

Meaning

Kisspeptin-10 Endogenous Regulation refers to the body’s internal control and modulation of the decapeptide Kisspeptin-10, a crucial neurohormone that acts as the primary gatekeeper for the onset of puberty and the maintenance of reproductive function. This peptide, produced by specific hypothalamic neurons, is the master regulator of the entire Hypothalamic-Pituitary-Gonadal (HPG) axis. Optimal endogenous regulation is essential for fertility, stable menstrual cycles, and balanced sex hormone production throughout the lifespan.
