Synaptic release of GABA by AgRP neurons is required for normal regulation of energy balance

The physiologic importance of GABAergic neurotransmission in hypothalamic neurocircuits is unknown. To examine the importance of GABA release from agouti-related protein (AgRP) neurons (which also release AgRP and neuropeptide Y), we generated mice with an AgRP neuron–specific deletion of vesicular GABA transporter.
