The endogenous opioid system consists of three opioid peptide precursor genes encoding enkephalins (preproenkephalin, Penk), dynorphins (preprodynorphin, Pdyn) and beta-endorphin (betaend), proopiomelanocortin (POMC) and three receptor genes encoding mu-opiod receptor (MOR), delta-opiod receptor (DOR) and kappa-opiod receptor (KOR).

It is becoming increasingly clear that astroglial cells are active participants in the process by which information is generated and disseminated within the central nervous system (CNS). In the hypothalamus, astrocytes regulate the secretory activity of neuroendocrine neurons. They contribute
