What is the Meaning of Melanocortin System?

The Melanocortin System is a complex neuroendocrine network centered in the hypothalamus that integrates signals related to energy homeostasis, appetite suppression, and energy expenditure. Its proper function is critical for maintaining healthy body composition.

What is the Origin of Melanocortin System?

This system is named for the melanocortin peptides, such as $alpha$-MSH, which were originally characterized for their role in regulating pigmentation in melanocytes, though their central regulatory roles are now better understood.

What is the Mechanism of Melanocortin System?

Activation of key receptors, particularly MC4R in the arcuate nucleus, leads to downstream signaling that promotes satiety and increases energy expenditure by modulating neuronal circuits controlling feeding behavior. Inverse agonists like AgRP block this anorexigenic signal, driving increased food-seeking behavior.
