Additive effect of 5-HT2C and CB1 receptor blockade on the regulation of sleep–wake cycle

摘要

BackgroundPrevious data show that serotonin 2C (5-HT2C) and cannabinoid 1 (CB1) receptors have a role in the modulation of sleep–wake cycle. Namely, antagonists on these receptors promoted wakefulness and inhibited rapid eye movement sleep (REMS) in rodents. The interaction of these receptors are also present in other physiological functions, such as the regulation of appetite. Blockade of 5-HT2C receptors modulat the effect of CB1 receptor antagonist, presumably in consecutive or interdependent steps. Here we investigate, whether previous blockade of 5-HT2C receptors can affect CB1 receptor functions in the sleep–wake regulation.
