PG - 1045-1058 LID - S1471-4914(23)00194-6 [pii] LID - 10.1016/j.molmed.2023.08.009 [doi] AB - The two monoamines serotonin and melatonin have recently been highlighted as potent regulators of islet hormone secretion and overall glucose homeostasis in the body. In fact, dysregulated signaling of both amines are implicated in beta-cell dysfunction and development of type 2 diabetes mellitus (T2DM). Serotonin is a key player in beta-cell physiology and plays a role in expansion of beta-cell mass. Melatonin regulates circadian rhythm and nutrient metabolism and reduces insulin release in human and rodent islets in vitro. Herein, we focus on the role of serotonin and melatonin in islet physiology and the pathophysiology of T2DM. This includes effects on hormone secretion, receptor expression, genetic variants influencing beta-cell function, melatonin treatment, and compounds that alter serotonin availability and signaling.
