There is Kisspeptin – And Then There is Kisspeptin [PDF]

open access: yesTrends in Endocrinology and Metabolism, 2015
While kisspeptin was initially found to function as a metastasis suppressor, after identification of its receptor KISS1R and their expression profiles in tissues such as the hypothalamus and adrenals, kisspeptin and KISS1R were predominantly assigned endocrine functions, including regulating puberty and fertility through their actions on hypothalamic ...

Kisspeptin antagonists: Unraveling the role of kisspeptin in reproductive physiology

Brain Research, 2010
Kisspeptin has recently been identified as a key neuroendocrine gatekeeper of reproduction and is essential for the initiation of human puberty and maintenance of adult reproduction. Kisspeptin neurons appear to be integrative sensors, as they respond to changes in numerous internal and external factors including nutrient and fat status, stress and sex

Immunocytochemical localization of kisspeptin and kisspeptin receptor in the primate testis

Journal of Medical Primatology, 2016
AbstractBackgroundHypothalamic kisspeptin–kisspeptin receptor signalling in primates ensures the successful progression into puberty during development and maintenance of reproductive capacity during adulthood. Human testis has been shown to express high‐to‐moderate levels of kisspeptin and kisspeptin receptor gene expression.

Kisspeptin and Prolactin

Seminars in Reproductive Medicine, 2019
AbstractThe relationship between elevated prolactin and infertility has been known for a long time, but the specific mechanism by which prolactin inhibited reproduction had been uncertain. The discovery of kisspeptin has provided novel insights into how prolactin might cause infertility, with extensive evidence that elevated prolactin inhibits ...

Biology of Kisspeptins

2010
In recent years, a substantial body of evidence has accumulated suggesting that the hypothalamic peptide hormone kisspeptin and its cognate receptor, G-protein-coupled receptor 54, play a fundamental role both as gatekeepers for the initiation of puberty and in the regulation of the hypothalamic-pituitary-gonadal axis.

Kisspeptin Antagonists

2013
Kisspeptin is now known to be an important regulator of the hypothalamic--pituitary-gonadal axis and is the target of a range of regulators, such as steroid hormone feedback, nutritional and metabolic regulation. Kisspeptin binds to its cognate receptor, KISS1R (also called GPR54), on GnRH neurons and stimulates their activity, which in turn provides ...

Kisspeptin in Reproduction

Seminars in Reproductive Medicine, 2007
Although the functions of kisspeptin originally were believed to be restricted to metastasis suppression, a novel role for this protein was discovered in 2003. Loss-of-function mutations in its receptor, GPR54, were found to cause absence of puberty and hypogonadotropic hypogonadism in humans.
