Expression of regulatory neuropeptides in the hypothalamus of red deer ( Cervus elaphus ) reveals anomalous relationships in the seasonal control of appetite and reproduction

Expression of regulatory neuropeptides in the hypothalamus of red deer ( Cervus elaphus ) reveals anomalous relationships in the seasonal control of appetite and reproduction

Highlights • We used immunochemistry to examine hypothalami of red deer for neuropeptides. • Kisspeptin-containing cells were positively associated with the breeding season. • GnIH immunoreactivity did not differ between seasons. • In females NPY was highest and POMC cells lowest in the non-breeding...

Zusammenfassung:Highlights • We used immunochemistry to examine hypothalami of red deer for neuropeptides. • Kisspeptin-containing cells were positively associated with the breeding season. • GnIH immunoreactivity did not differ between seasons. • In females NPY was highest and POMC cells lowest in the non-breeding season. • Males displayed the converse pattern for these appetite-regulating peptides.
