Kisspeptin, also known as metastin, is an endogenous protein that is important for hormonal signaling, particularly during puberty and in relation to reproduction. It affects not only maturation and the ability to conceive, but possibly also mood, behavior and even kidney function.
Interestingly, this protein was identified in the brain. There, it may inhibit tumor growth and hinder the spread of metastases. This discovery attracted considerable interest from researchers.
Kisspeptin-10, derived from the kisspeptin protein, has attracted considerable attention recently because of its major role in stimulating the release of gonadotropin-releasing hormone (GnRH), which is a critical hormone for sexual development and reproductive function.
Research shows that Kisspeptin-10 may directly stimulate GnRH release at GnRH nerve terminals. This provides a new point of action for Kisspeptin-10, creating opportunities for potential therapeutic applications.
Stimulation of gonadotropin secretion by Kisspeptin-10 in women appears to be regulated by sex steroid feedback. This finding may be important for understanding hormonal balance and women's reproductive health.
Kisspeptin-10 is a potent activator of luteinizing hormone (LH) that affects the frequency of its release. Studies show that Kisspeptin-10 injections noticeably stimulate LH secretion in men, while regular administration may increase testosterone levels as well as the frequency and volume of LH release.
In men with hypogonadism and type 2 diabetes, Kisspeptin-10 increases the frequency of LH pulses and its secretion, supporting this concept.
In adolescents at Tanner stage 5 of puberty, Kisspeptin-10 injections clearly increase plasma LH and testosterone levels.
Interestingly, Kisspeptin-10 has also been associated with other beneficial effects in addition to hormonal regulation. These include increased sexual desire, improved mood and behavior, and regulation of reproductive function.
It is suggested that this peptide may be a useful adjunct to testosterone replacement therapy for maintaining fertility and preventing testicular shrinkage.
Kisspeptin-10 is important for maintaining the body's energy balance.
Research shows that kisspeptin neurons are involved in energy regulation. They probably link energy balance to reproductive function in some way.
Animal studies indicate that kisspeptin affects various metabolic parameters, including weight and energy. Kisspeptin-10 may regulate energy balance directly.
Energy balance is closely linked to reproductive function. Kisspeptin in the hypothalamus is thought to be involved in regulating this balance. Problems with positive or negative energy balance often lead to impaired fertility, such as hypothalamic hypogonadism.
There is evidence that brain-derived neurotrophic factor (BDNF) may be an important element through which melanocortin-4 regulates energy balance, and Kisspeptin-10 may play a role in this process.
Overall, peripheral hormones such as ghrelin and PYY3-36, together with the neuropeptide kisspeptin, are new participants in the neuroendocrine networks that regulate energy balance.
Preliminary data indicate a possible connection between kisspeptin and brain function. In rat studies, administration of kisspeptin led to improved memory. Although the mechanism of this action is not fully understood, it may affect neural activity.
It is also suggested that kisspeptin may affect areas of the brain responsible for mood and cognitive abilities, including the hippocampus and amygdala. However, there is currently no direct evidence, and further studies are needed to confirm the effect of Kisspeptin-10 on memory improvement.
Recent work has examined how Kisspeptin-10 may affect mood. Experiments have shown that kisspeptin may alter brain activity, improving sexual and emotional functions. Effects on both positive and negative emotions have been observed.
Another study showed that kisspeptin may reduce low mood. However, it did not affect other hormones that influence the limbic system.
A review of the literature shows that kisspeptin signaling is increasingly implicated in behavior, emotion and cognition. Kisspeptin-10 may play a role in this, but further work is needed for confirmation.
Kisspeptin has also been observed to act as an antidepressant and affect feelings of fear, suggesting a possible role in emotional processing.
Nutrition research suggests that kisspeptin may act as an intermediary between sex, emotions and reproduction.
Kisspeptin is usually studied in relation to the reproductive system, but it is also important for the kidneys. It is studied in different parts of kidney tissue, where it is probably involved in signaling that regulates kidney function. Experiments in mice lacking the Kiss1 receptor indicate that kisspeptin is required for normal kidney development. Without it, problems with glomerular development may occur. It is not yet clear whether it acts independently or through other hormones and growth factors, but its importance for the kidneys is evident.
Kisspeptin-10 appears to affect not only reproduction and the kidneys, but also the heart and blood vessels. Studies in mice with heart problems indicate that kisspeptin may affect different blood vessels in different ways. It may control their constriction and even alter the amount of blood pumped by the heart. This is thought to be related to kisspeptin's ability to stimulate or inhibit the formation of new blood vessels. This mechanism helps explain how the peptide acts against tumors: by regulating blood vessels, it may reduce the likelihood of metastases spreading.

Кісспептин, він же метастатин, - це наш власний білок, важливий для гормонального зв'язку, особливо в період статевого дозрівання і коли йдеться про дітонародження. Він впливає не тільки на дозрівання та здатність до зачаття, але, можливо, і на наш настрій, поведінку і навіть на роботу нирок. Цікаво, що цей білок знайшли у мозку. Там він, ймовірно, може гальмувати зростання пухлин та заважати поширенню метастазів. Це відкриття дуже зацікавило вчених.
