Direct inhibition of arcuate kisspeptin neurones by neuropeptide Y in the male and female mouse

Adverse energy states exert a potent suppressive influence on the reproductive axis by inhibiting the pulsatile release of gonadotrophin-releasing hormone and luteinising hormone. One potential mechanism underlying this involves the metabolic-sensing pro-opiomelanocortin and agouti-related peptide/neuropeptide Y (AgRP/NPY) neuronal populations directly controlling the activity of the arcuate nucleus kisspeptin neurones comprising the...
