Role of kisspeptin-10 (KiSS-10), neurokinin B (NKB) and dynorphin (Dyn) A in the endocrine regulation of puberty, based on Navarro (20) and Pinilla et al. (24) ARC – arcuate nucleus; KNDy – kisspeptin, neurokinin B and dynorphin; GPR54 – G protein-related membrane receptor 54; NK3R – neurokinin 3 receptor; KOR – kappa opioid receptor; GnRH – gonadotropin-releasing hormone; LH – luteinising hormone; FSH – follicle-stimulating hormone; + – positive action; − – negative action; ? – unknown action
