Chronic treatment with eliprodil produced both a significant downregulation of beta-adrenoceptors and a reduction in the potency of glycine to inhibit [3H] 5,7-dichlorokynurenic acid binding to strychnine-insensitive glycine receptors in neocortical membranes.

Changes to the binding properties of cortical N-methyl-D-aspartic acid (NMDA) and beta-adrenergic receptors have both been reported as potential indicators of antidepressant activity.
A decrease in the potency of glycine to displace the strychnine insensitive glycine antagonist [3H] 5,7 dichlorokynurenic acid (5,7 DCKA) was observed in cortical homogenates of OB rats when compared to sham-operated controls.

Chronic (14 day) but not acute (1 day) treatment of mice with clinically active antidepressants produces a significant (approximately 1.8-4.3 fold) reduction in the potency of glycine to inhibit [3H]-5,7-dichlorkynurenic acid (5,7-DCKA) binding to strychnine-insensitive glycine receptors in neocortical membranes.
These findings indicate that the antidepressant-induced reduction in the IC50 of glycine to inhibit [3H]-5,7-DCKA binding is: 1) a slowly developing, adaptive phenomenon; 2) remarkably persistent after cessation of treatment; and 3) a significantly better predictor of antidepressant activity (22 of 23 drugs) than either beta adrenoceptor down-regulation (15 of 23 drugs) or efficacy in the forced swim test (13 of 23 drugs) [P < .01 vs. each measure, Fisher's Exact Test].

NA-induced hyperpolarizing effects were maintained in the presence of tetrodotoxin (TTX), 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX), d,l-2-amino-5-phosphonopentanoic acid (AP5), picrotoxin and strychnine, a Na (+) channel, ionotropic glutamate receptor, GABA (A) and glycine receptor antagonists, respectively, indicating that the effects of NA are direct on the postsynaptic SG neurons.

Monosynaptic excitatory postsynaptic currents (EPSCs) were evoked by electrical stimulation of the nucleus intercalatus in the presence of strychnine (5 microM) and bicuculline (10 microM).
Conversely, the beta-adrenoceptor antagonist popranolol (5 microM), and the alpha1-, alpha2B- and alpha2C-antagonist prazosin (2 microM) were without effect.

Baseline spontaneous postsynaptic potentials were abolished by strychnine (1 microM), bicuculline (30 microM) or both.
