Hyperphagia alters expression of hypothalamic 5-HT2C and 5-HT1B receptor genes and plasma des-acyl ghrelin levels in Ay mice.


The central melanocortin (MC) pathway is suggested to mediate satiety signaling downstream of serotonin (5-HT)2C receptors. 5-HT2C receptor mutant mice consume more food, which leads to late-onset obesity and impaired glucose tolerance. Ay mice with ectopic expression of the agouti peptide, which leads to a perturbation of the central MC pathway, develop… (More)
