Abstract:
The recently discovered peptide phoenixin was initially implicated in reproduction as a regulator of gonadotropin-releasing hormone (GnRH)-stimulated luteinizing hormone (LH) release from the pituitary. Subsequently, various functions of phoenixin have been demonstrated including mediation of itching sensation, stimulation of vasopressin secretion, stimulation of white adipogenesis and hypothalamic nutrient sensing. Subsequently, additional actions of phoenixin have been described, namely effects on behavior. A systematic search of four data bases was performed and original articles selected accordingly. The present systematic review will present the current knowledge on the effects of phoenixin on different behaviors such as anxiety and food intake as well as cognition. Lastly, gaps in knowledge will be mentioned to stimulate further research.
