Abstract

Nociceptin, an endogenous ligand for the orphan receptor ORL1, has recently been described. In this study we have shown that nociception inhibits 46 mM K(+)-stimulated glutamate release from rat perfused cerebrocortical slices with an IC50 of 51 nM. At 100 nM the inhibition amounted to 68 +/- 14% and was naloxone (10 microM)-insensitive excluding an activation of mu, delta and kappa opioid receptors. These data demonstrate the functional coupling of ORL1 in glutamatergic neurones and implicates a role for nociceptin in glutamatergic neurotransmission.
