Monoamines' role in islet cell function and type 2 diabetes risk

Trends Mol Med. 2023 Sep 16:S1471-4914(23)00194-6. doi: 10.1016/j.molmed.2023.08.009. Online ahead of print.ABSTRACTThe 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 β-cell dysfunction and development of type 2 diabetes mellitus (T2DM). Serotonin is a key player in β-cell physiology and plays a role in expansion of β-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 β-cell function, melatonin treatment, and compounds that alter serotonin availability and signaling.PMID:37722934 | DOI:10.1016/j.molmed.2023.08.009
