Researchers at UT Southwestern Medical Center have discovered that a crucial developmental process in the brain’s hypothalamus may influence how susceptible individuals are to obesity. Their preclinical findings, published in Neuron, show that a transcription factor called Otp acts as a molecular “switch” that directs immature hypothalamic neurons toward either appetite-suppressing or appetite-stimulating fates—their ultimate identities as specialized cells. The researchers found that disrupting this switch alters feeding behavior and protects mice from diet-induced obesity.
