What is the Meaning of Kisspeptin Signaling?

Kisspeptin Signaling is the pivotal neuroendocrine pathway in the hypothalamus that acts as the master regulator of the reproductive axis in both males and females. The process involves the binding of the neuropeptide kisspeptin to its specific receptor, KISS1R (GPR54), located on the Gonadotropin-Releasing Hormone (GnRH) neurons. This signaling cascade is absolutely essential for the onset of puberty and the maintenance of fertility throughout adulthood by controlling the pulsatile release of GnRH.

What is the Origin of Kisspeptin Signaling?

The neuropeptide kisspeptin was initially discovered in 1996 as a metastasis-suppressor gene product, hence its original name, metastin, but its critical role in reproduction was identified in the early 2000s when mutations in its receptor were linked to human idiopathic hypogonadotropic hypogonadism. This discovery fundamentally redefined the central neuroendocrine control of the hypothalamic-pituitary-gonadal (HPG) axis, establishing kisspeptin neurons as the key pulse generator for reproductive function.

What is the Mechanism of Kisspeptin Signaling?

The mechanism of Kisspeptin Signaling is direct and stimulatory: kisspeptin neurons, often co-expressing neurokinin B and dynorphin (KNDy neurons), release kisspeptin onto the GnRH neurons in the hypothalamus. This binding to KISS1R activates a G-protein coupled receptor cascade that rapidly depolarizes the GnRH neuron, triggering the pulsatile release of GnRH into the portal circulation. GnRH then stimulates the pituitary to secrete Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), thereby coordinating the entire reproductive endocrine cascade.
