What is Neuropeptide kisspeptin?
Neuropeptide Kisspeptin, also known as kiss1, was first identified in 1996 as a transfer suppressor in human cell lines.

The Kiss1 gene encodes a protein composed of 145 amino acids. In the human body, this protein is processed into a 54-amino acid peptide called kisspeptin, which, like several other neuropeptides, has a unique RF-amide motifs in its C-terminal region. It binds and activates the G-protein-coupled receptor GPR54, which stimulates hypothalamic neurons to release GnRH, leading to pituitary gonadotropin (LH and FSH) and sex hormone secretion.

Kisspeptin is a key regulator of the onset of puberty, regulation of sex hormone-mediated gonadotropin secretion, and fertility control. Inactivated or activated mutations in Kiss1 and GPR54 genes are associated with hypogonadotropin hypogonadism (IHH) and precocious puberty (CPP).

Neuropeptide kisspeptin has three main functions
Activation of GnRH neurons in the hypothalamus leads to GnRH release, which leads to the release of FSH and LH.
Inhibit the development of tumors.
Treat low libido.
How kisspeptin activates GnRH Neurons
Bodybuilder is all too familiar with HPTA, the hypothalamic-pituitary-testicular axis whose positive and negative feedback controls the production and cessation of testosterone in men. HPGA is the hypothalamic-pituitary-gonadal axis. HPGA controls all stages of reproduction. The hypothalamus produces GnRH into the anterior pituitary and stimulates the secretion of LH and FSH. Slow GnRH pulsation is conducive to FSH secretion, while fast pulse frequency supports LH secretion.

What is the hypothalamic-Pituitary-gonadal axis (HPGA)?
The positive and negative feedback of the hypothalamic-pituitary-gonadal axis (HPGA) controls the secretion and cessation of sex hormones in both men and women, and its normal work maintains the normal levels of sex hormones in both men and women, thus maintaining physiological functions. This is something that happens every day in the adult body, and HPGA plays an important role in adult men and women. However, HPGA is not form in adulthood; all its components are establish in the foetus, activate in the neonatal period, then become stationary in childhood and cannot reactivate until puberty.

GnRH Secretion Triggers Onset of Puberty
Hypothalamic gonadotropin-releasing hormone (GnRH) neurons are functional at birth, but after a perinatal hormone surge, they are directly suppressed in infancy and no longer function. Until puberty, dormant GnRH neurons are awakened to rerelease GnRH. GnRH secreted by the hypothalamus drives the pituitary gland to secrete the release of gonadotropin (follicle-stimulating hormone FSH and luteinizing hormone LH).

In males, the increased release of GnRH pulses during puberty activates gonadotropin secretion, which in turn leads to increased testosterone secretion levels in the testis, binding with FSH to initiate spermatogenesis. Tetanic LH secretion consists of intermittent episodes of hormone secretion that reflect the corresponding pattern of pulsing GnRH release in the hypothalamus.

In women, increased impulsive GnRH release also drives gonadotropin secretion, which is responsible for follicular formation and estradiol (E2) secretion.

After puberty is complete, HPGA is officially complete and functional. Puberty begins through increase production of GnRH, however, it remains an open question how GnRH neurons activate during puberty.

Neuropeptide Kisspeptin controls GnRH pulse Production
Subsequent 15 years of research have shown that hypothalamic kisspeptin acts upstream of GnRH and mediates sex hormone feedback and metabolism on the reproductive axis. This neuropeptide is necessary to start puberty and maintain normal reproductive function,

Clinical studies have shown that inactivated mutations in the GPR54 gene lead to impaired pubertal maturation and reproductive function in humans, accompanied by insufficient production of gonadotropin, or hypogonadotropin. GPR54 is an orphan G-protein-couple receptor,
