A Role for Kisspeptins in the Regulation of Gonadotropin Secretion in the Mouse. [PDF]
Endocrinology, 2004 Kisspeptins are products of the KiSS-1 gene, which bind to a G protein-coupled receptor known as GPR54. Mutations or targeted disruptions in the GPR54 gene cause hypogonadotropic hypogonadism in humans and mice, suggesting that ...

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 ...

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: Unraveling the role of kisspeptin in reproductive physiology
Brain Research, 2010Kisspeptin 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

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 ...

Immunocytochemical localization of kisspeptin and kisspeptin receptor in the primate testis
Journal of Medical Primatology, 2016AbstractBackgroundHypothalamic 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.

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.

Kisspeptin and Glucose Homeostasis
Seminars in Reproductive Medicine, 2019AbstractKisspeptin has well-established critical roles in the control of reproduction and fertility. Recently, evidence has emerged that suggests kisspeptin may have additional roles in the regulation of glucose homeostasis. Conflicting reports on the effects of kisspeptin on insulin secretion in animal models have been published, which cannot be fully

Kisspeptin and Seasonality of Reproduction
2013Wild and domesticated species display seasonality in reproductive function, controlled predominantly by photoperiod. Seasonal alterations in breeding status are caused by changes in the secretion of gonadotropin-releasing hormone (GnRH) that are mediated by upstream neuronal afferents that regulate the GnRH cells.

Kisspeptin as a Behavioral Hormone
Seminars in Reproductive Medicine, 2019AbstractSuccessful reproduction is dependent not only on hormonal endocrine responses but also on suitable partner selection, copulatory acts, as well as associated emotional, behavioral, and cognitive processes many of which are supported by the limbic system.
