In spontaneously withdrawn LC neurons from morphine-dependent rats, met-enkephalin (pD2 7.1, maximum inhibition 49%) and morphine (pD2 6.5, maximum inhibition 33%), inhibited IBa in all cells.

The endogenous opioid agonist methionine-enkephalin (met-enkephalin, pEC50 6.8, maximum inhibition 40%), the putative endogenous mu-opioid agonist endomorphin-1 (pEC50 6.2, maximum inhibition 35%) and the mu-opioid selective agonist DAMGO (Tyr-D-Ala-Gly-N-Me-Phe-Gly-ol enkephalin, pEC50 6.9, maximum inhibition 40%) inhibited IBa in 70% of mouse PAG neurons.

Nociceptin (EC50, 5 nM) and baclofen (EC50, 0.8 microM) inhibited IBa in all PAG neurons, while the opioid agonist methionine enkephalin (met-enkephalin; 300 nM-10 microM) inhibited IBa in 40 % of neurons.

Half-maximal inhibition of Ba2+ current (IBa) amplitude was obtained with 270 nM Met-enkephalin or Leu-enkephalin.

Application of noradrenaline (NA), ATP, methionine-enkephalin (ENK) or protons decreased IBa.

In order to address this issue, we analyzed the effects of [d-Ala2, d-Leu5]-enkephalin (DADLE) on whole-cell Ba2+ currents (IBa) through voltage-gated Ca2+ channels in NG108-15 neuroblastoma x glioma hybrid cells.
