Abstract: Adenosine, the product of ATP, widely presented in the brain is proposed to be an endogenous sleep-promoting substance. Among 4 subtypes of adenosine receptor (R), A1R, A2AR, A2BR and A3R, it has been reported that both adenosine A1R and A2AR mediate the somnogenic effects of adenosine. Activation of A1R in the arousal histaminergic posterior hypothalamus, cholinergic basal forebrain and so on promotes sleep. A2AR is mainly localized in the caudate-putaman, nucleus accumbens, olfactory tubercles. Activation of A2AR significantly promotes sleep. A2AR mediates the somnogenic effects of prostaglandin D2, and acts as the target of caffeine. However, the roles of A1R and A2AR in sleep-wake regulation are in debate. This review summarizes the progress in the roles of adenosine receptors in sleep-wake regulation.
