BMP Receptor 1A Regulates Development of Hypothalamic Circuits Critical for Feeding Behavior

Hypothalamic neural circuits are known to regulate energy homeostasis and feeding behavior, but how these circuits are established during development is not well understood. Here we report that embryonic neural progenitors that express the transcription factor OLIG1 contribute neurons to the ventral hypothalamus including the arcuate nucleus (ARH), a center that regulates feeding behavior. Ablation of bone morphogenetic protein receptor 1a...
