Gut peptides (GLP-1, PYY, CCK, ghrelin) converge on the central melanocortin system (POMC/AgRP neurons) as a common integration point for peripheral appetite signals — the brain's final common pathway for satiety.

What the researchers found
Peripheral gut peptides (GLP-1, PYY, CCK, ghrelin) converge on the hypothalamic melanocortin system (POMC/AgRP neurons) as the central integration point, with melanocortin neurons serving as the final common pathway translating gut signals into eating behavior.
