Mt1 (Mtnr1A) Receptor Neurons is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
MT1 receptor neurons (also termed MTNR1A neurons or melatonin type 1 receptor neurons) are neurons that express the MT1 melatonin receptor (encoded by the MTNR1A gene). These neurons mediate the effects of melatonin on circadian rhythm regulation, sleep-wake cycles, mood modulation, and various neurophysiological functions. The MT1 receptor is a G-protein coupled receptor (GPCR) that is highly expressed in the suprachiasmatic nucleus (SCN) and other brain regions involved in circadian timing. [@melatonin2018]
Melatonin, often called the "hormone of darkness," is synthesized primarily by the pineal gland during nighttime hours. MT1 receptors on neurons transduce melatonin signals to synchronize circadian rhythms with the light-dark cycle. [@receptor2019]
