title: Leptin grows up and gets a neural network.
abstract: Studies seeking a dominant site of action for the hormone leptin have focused on leptin receptor-expressing neuropeptidergic neurons. In this issue, Vong et al. show that leptin regulates energy homeostasis predominantly via a distributed network of GABAergic neurons.
