G-protein-gated inwardly rectifying K+ channel 4 (GIRK4) immunoreactivity in chemically defined neurons of the hypothalamic arcuate nucleus that control body weight

► First demonstration of the localization of GIRK4 protein in hypothalamus. ► Demonstration of GIRK4 protein in POMC/CART neurons of arcuate nucleus. ► Demonstration of GIRK4 protein in NPY/AgRP neurons of arcuate nucleus.
