Zusammenfassung
Recently, many investigations on the functional interactions between the pineal gland and glucose metabolism have been collected: (i) Melatonin influences insulin secretion and, in general, decreases insulin secretion both in vivo and in vitro. Moreover, the effects of melatonin on insulin secretion have been shown to be receptor mediated. Expression of the melatonin receptor MT1 and, more recently, that of the MT2 receptor have been detected in the pancreas. (ii) It has also been determined that the effects on insulin secretion are mediated through specific, high-affinity pertussis-toxin-sensitive Gi-protein-co…
