Genes for prostaglandin d synthase and receptor as well as adenosine A2A receptor are involved in the homeostatic regulation of nrem sleep.
(1) Prostaglandin D2 is essential for the maintenance of the sleep state. (2) The adenosine and A2A receptor system is a link between the humoral and neural mechanisms of sleep-wake regulation. (3) Prostaglandin D2 plays a crucial role in the homeostatic regulation of NREM sleep. Finally, it may not be too far-fetched to say that prostaglandin D2 was most likely the endogenous sleep substance described by Piéron and Ishimori about 100 years ago, and possibly the sleep-inducing factor reported by Professor Jouvet and coworkers some twenty years ago.
