Figure 1 POMC-derived peptides control body weight and adrenal function
Figure 1 | POMC-derived peptides control body weight and adrenal function. a | Melanocyte stimulating hormones (MSH, red arrows) released by hypothalamic proopiomelanocortin (POMC) neurons activate melanocortin-4 receptor (MC4R) to induce satiety and increase energy expenditure. The resulting hunger score is 3 on a scale of 1 (minimum) to 10 (maximum). Adrenocorticotropic hormone (ACTH) secreted from POMC-expressing pituitary corticotrophs is essential for normal development of the adrenal cortex and stimulates cortisol secretion. b | POMC-deficient individuals lack melanocortin signalling in the brain and consequently have constant hunger and development of severe obesity. ACTH-deficiency can be managed by hydrocortisone replacement therapy, but the adrenal glands remain dystrophic. c | Setmelanotide treatment replaces MSH in the brain, leading to a hunger score of 1, and stimulates MC4R to restore normal energy balance, thereby reducing excess fat mass and body weight.
