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.
