Kisspeptin-10

As part of one 2017 study, a literature review was conducted for all articles published from 1999 to 2016. Upon review, it was suggested that experimental data may support the hypothesis that the Kisspeptin-10 system (including the KISS1 gene and its products, GPR54 receptors) may possibly regulate the release of gonadotropin hormones. Furthermore, certain studies were conducted in experimental animal models with similar characteristics as hypogonadotropic hypogonadism (HH) and polycystic ovarian syndrome (PCOS).

The main goal of this study was to evaluate the potential of Kisspeptin-10 peptide in research models of stunted development. Researchers hypothesized that the peptide might stimulate gonadal hormonal release and regulate the reproductive system in experimental models. The study randomly introduced either Kisspeptin-10 or gonadotropin-releasing hormone (GnRH), with LH levels monitored overnight.

The main purpose of this study was to understand the potential of Kisspeptin-10 on limbic brain activity. Following Kisspeptin-10 exposure in the research models, results were monitored via neuroimaging and psychometric analysis. The data from the study suggested that the peptide appeared to have led to some enhanced limbic brain activity. The models appeared to exhibit an increased response towards sexual and bonding stimuli.

Kisspeptin-10 is considered to be widely distributed in brain sites, including the hippocampus, cerebellum, posterior hypothalamus, and septum. This study was conducted to examine the potential impact of Kisspeptin-10 on food intake in adult male mice aged between 6 and 8 weeks. Results suggested that the peptide in overnight fasted mice may have decreased food intake during the first 3-to-12-hour period, with food intake then reportedly increasing during the 12-to-16-hour period.

The accumulation of amyloid-beta (Aβ) and alpha-synuclein (α-syn) within cholinergic neurons is believed to damage and potentially cause dysfunction within important central nervous system structures. It has been proposed that Kisspeptin-10 may attach to Aβ on the outside of cells, which may in turn possibly reduce the harmful actions of Aβ. Studies have suggested that Kisspeptin-10 peptides may counteract the damaging actions of Aβ, prion protein, and Islet Amyloid Polypeptide without being hindered by antagonists of the kisspeptin receptor.
