Can the kisspeptin help us in the understanding of pathology of some neurodegenerative brain diseases?

It is already known that the discovery of kisspeptin was a revolutionary step in the understanding of neuroendocrine regulation of reproduction. Kisspeptin is one of the main moderators of the gonadotropic axis, but the kisspeptin gene is known to be expressed in various regions of the central nervous system. The activity of kisspeptin is not limited to hypothalamic pituitary gonadal axis; it participates in the regulation of multiple neuronal circuits in the limbic system. The limbic system is a part of the brain involved in behavioural and emotional reactions, and disturbances in its functioning may be the source of some psychiatric as well as degenerative disorders. In the present review, we summarise the current state of knowledge concerning the role of kisspeptin in the limbic system and a new hope for the treatment of disturbances in its functioning.
