20331561 Adermark L, Clarke RB, Olsson T, Hansson E, Soderpalm B, Ericson M: Implications for glycine receptors and astrocytes in ethanol-induced elevation of dopamine levels in the nucleus accumbens. Addict Biol. 2010 Mar 10.

ABSTRACT Elevated dopamine levels are believed to contribute to the rewarding sensation of ethanol (EtOH), and previous research has shown that strychnine-sensitive glycine receptors in the nucleus accumbens (nAc) are involved in regulating dopamine release and in mediating the reinforcing effects of EtOH.
The EtOH-induced cell swelling was inhibited in cultures treated with the Na (+)/K (+)/2Cl (-) cotransporter blocker furosemide (1 mM), Na (+)/K (+)-ATPase inhibitor ouabain (0.1 mM), potassium channel inhibitor BaCl (2) (50 microM) and in cultures containing low extracellular sodium concentration (3 mM).

These results indicate that the nicotinic response in DLSN neurons may be mediated by a metabotropic nicotinic receptor coupled to a calcium-dependent potassium channel through the activation of a G-protein and release of intracellular calcium stores.
Intracellular recording from DSLN neurons in a brain slice preparation was used to determine whether chlorisondamine, trimethaphan, cytisine or strychnine inhibited the membrane hyperpolarization in response to application of the nicotinic agonist 1,1-dimethyl-4-phenylpiperazinium (DMPP).

Substantial changes in fluorescence of calcium green-labeled motoneurons were also observed during motoneuron bursting induced by bath application of the glycine receptor antagonist strychnine or the potassium channel blocker 4-aminopyridine (4-AP). 7.

This effect on the evoked EPSCS was blocked by a potassium channel blocker, 4-aminopyridine (4-AP) in a dose-dependent manner.

This atypical property of the M-cell was mediated by dendrotoxin-I (DTX-I)-sensitive voltage-gated potassium channels together with recurrent inhibition, because combined application of DTX-I, strychnine, and bicuculline led to continuous repetitive firing in M-cells.
