Reprogramming in melanocortin modulates diet-induced obesity.

Hypothalamic proopiomelanocortin (POMC) neurons promote satiety, while agouti-related peptide (AgRP) neurons drive hunger and maintain energy balance.

However, it is not clear how the system is diversified developmentally.

The researchers in this study show that transcription factor Otp act as a developmental ‘‘switch’’ in the hypothalamus and determines whether immature neurons become appetite suppressing (POMC) or appetite stimulating (AgRP).

Disrupting this switch reshapes feeding behavior and protects mice from obesity, revealing how early life programming shapes lifelong metabolic health. sciencenewshighlights ScienceMission https://sciencemission.com/melanocortin-neurons-modulates-diet-induced-obesity

Xu et al. show that a developmental “switch” in the hypothalamus determines whether immature neurons become appetite suppressing or appetite stimulating.
