  • Agouti-related peptide (AgRP) producing neurons regulate food intake and metabolic processes in peripheral organs. Here, the authors show that hypothalamic AgRP neurons alter whole body substrate utilization to favour carbohydrate usage and lipid storage.

  • In this study, the authors show that conditional deletion of leptin receptors from astrocytes alters their morphology and results in an increase in the number of synapses on POMC and AgRP neurons of the arcuate nucleus. In addition, they find that loss of leptin response in astrocytes modified leptin- and ghrelin-controlled food intake.
