“These data show inhibition by elevated circulating OT levels of glucocorticoid-induced, but not basal, leptin secretion in normal weight subjects, suggesting a possible role for OT in the regulatory control of leptin.”

“This review assesses the potential … and peripheral targets by which oxytocin may inhibit body weight gain, its regulation by anorexigenic and orexigenic signals, and its potential use as a therapy that can circumvent leptin resistance and reverse the behavioral and metabolic abnormalities associated with DIO and genetically obese models.”

“These findings extend recent evidence suggesting that oxytocin circumvents leptin resistance and induces weight-loss in DIO animals through a mechanism involving activation of neurons in the NTS and AP, key hindbrain areas for processing satiety-related inputs.”

“Central administration of leptin significantly reduced both plasma oxytocin and hypothalamic noradrenaline responses to CCK at 20 min following the treatments.”
“In conclusion, leptin may inhibit oxytocin secretion by lowering noradrenergic neurotransmission in the PVN.”
“The main hypothesis was that leptin has an inhibitory action on oxytocin secretion and hypothalamic release of noradrenaline.”
“Using immunocytochemistry, we found that an anorectic dose of leptin administered into the third ventricle (3V) increased twofold the number of pPVN oxytocin neurons that expressed Fos.”

“The results suggest that leptin may inhibit the secretion of both oxytocin and vasopressin by inhibiting the electrical activity of neurones in the SON via direct action.”
