Dynorphin A (DYN)-containing cells play a key role in conveying the negative feedback influence of progesterone upon pulsatile gonadotrophin-releasing hormone (GnRH) secretion in the ewe. A very high percentage of DYN cells in the arcuate nucleus express the progesterone receptor; another population of arcuate nucleus cells that also express steroid receptors in the sheep are those that express the tachykinin peptide, neurokinin B (NKB). Both DYN and NKB fibres have been shown to form close… CONTINUE READING
