BackgroundAppetite is complex, however to address the obesity epidemic, therapeutic agents would have to significantly influence appetite. Currently the most effective treatment for obesity is bariatric surgery because it reduces hunger and increases satiety. The satiety gut hormones such as peptide YY (PYY) and glucagon like peptide 1 (GLP-1) reduce appetite and food intake. Compared to lean and obese subjects, exaggerated postprandial responses of PYY ...

3-iodothyronamine (T1AM) is a novel, endogenous rapid acting biogenic amine, which is a potent agonist of the G-protein coupled trace amine-associated receptor 1, TAAR1. It has been suggested that endogenous T1AM could be generated by enzymatic deiodonation and decarboxylation of T4. The presence of T1AM in rat brain and the distribution of the TAAR1 receptor in the hypothalamus suggest that T1AM may affect food intake and regulate e...

Introduction: Primary adrenal insufficiency (PAI) can be of autoimmune origin (AI), non-autoimmune origin (bilateral adrenalectomy, acute hemorrhage, infection) (NAI) or pharmaceutical (mitotane) origin. Studies have shown that these patients develop long-term morbidities and increased mortality due to excessive glucocorticoid tissue exposure. Data about differences concerning hydrocortisone (HC) needs, cortisol hormonal levels and metabolic parameters in these patients are sc...

Kisspeptin, the endogenous ligand of the GPR54 receptor, is a key regulator of the hypothalamo-pituitary-gonadal (HPG) axis. GPR54-null mice exhibit reproductive dysfunction and exogenous kisspeptin potently stimulates the HPG axis in rodents, primates and human males. The effects of kisspeptin administration to human females are not known.Aim: To investigate the effects of kisspeptin on luteinising hormone (LH) release during the menstrual cycle in fema...
