A recent study from the Research Institute at McGill University Health Center may improve the treatment of sleep disorders and neurological(神经系统的) conditions.
Scientists have made a significant advancement in comprehending sleep mechanisms, identifying the melatonin(褪黑素) receptor MTI as a key regulator of REM(Rapid Eye Movement) sleep. This discovery holds promise for new treatments for sleep disorders and related neuropsychiatric conditions.
REM sleep is crucial for dreaming, memory consolidation, and emotional regulation. In the brain, the melatonin MT1 receptor affects a type of neuron(神经元) that synthesizes(合成) the neurotransmitter and hormone(荷尔蒙) noradrenaline(降肾上腺素), found in an area known as theLocus Coeruleus, or“blue spot” in Latin. During REM sleep, these neurons quiet down and stop their activity. Serious conditions such as Parkinson′s disease and Lewy body dementia(痴呆)—which currently lack effective treatments — are linked to disruptions in REM sleep.
“This discovery not only advances our understanding of sleep mechanisms but also holds significant clinical potential,” said Gabriella Gobbi, principal investigator of a new study published in the Journal of Neuroscience.
Until now, the specific receptor(受体) touching off REM sleep had escaped scientists. The new study has identified the melatonin MT1 receptor as an important regulator of this sleep stage. Using a novel drug targeting MT1 receptors, researchers successfully enhanced REM sleep duration in experimental animals, while simultaneously reducing neuronal activity.
“Currently, there are no drugs specifically targeting REM sleep. Most hypnotic(安眠) drugs on the market, while extending total sleep duration, tend to adversely affect REM sleep,” said Dr.Stefano Comai, co-senior author of the study and Professor at the University of Padua and AdjunctProfessor at McGill University.
Further research into the neurobiology and pharmacology(药理学) of REM sleep is crucial for developing targeted treatments that could improve the quality of life for patients affected by these diseases, according to the researchers. As scientists continue to explore the complexities of sleep regulation, the hope for effective interventions in neurological disorders grows increasingly promising.
