The mechanism underlying the depressant effect of opioids on neuronal activity within the neocortex is still not clear. Three modes of action have been suggested: (1) inhibition by activation of postsynaptic potassium channels, (2) interaction with postsynaptic glutamate receptors, and

Electrophoresis, 27(5-6), 1199-1208 (2006-03-09)
Nonaqueous capillary electrophoresis with electrochemical detection (NACE-ED) was applied to the analysis of enkephalin peptides. The effect of different buffer compositions on the electrophoretic behavior of methionine enkephalin, leucine enkephalin, and [D-Ala2]-leucine enkephalin was studied. Separation of the protonated and

Rat-1 fibroblasts were transfected with a cDNA encoding the mouse delta opioid receptor. Two separate clones, D2 (which expressed some 6 pmol of the receptor/mg of membrane protein) and DOE (which expressed some 0.2 pmol/mg of membrane protein), were examined

Leucine enkephalin (YGGFL) effects on markers for transcellular and paracellular permeation across the blood-brain barrier (BBB) were investigated in vitro with bovine brain microvessel endothelial cell (BMEC) monolayers in primary culture. Intact YGGFL, but not metabolites of YGGFL, stimulated BMEC

Opiates increase firing of rat medial vestibular nucleus neurons. We have attempted to determine the mechanism of these excitatory opiate actions by extracellular recording of neuronal activity with ionophoretic application of opiate agonists and bath application of antagonists. The spontaneous
