Abstract

γ-Aminobutyric acid type A receptors (GABARs) have long been implicated in mediating ethanol (EtOH) actions, but so far most of the reported recombinant GABAR combinations have shown EtOH responses only at fairly high concentrations (≥60 mM). We show that GABARs containing the δ-subunit, which are highly sensitive to γ-aminobutyric acid, slowly inactivating, and thought to be located outside of synapses, are enhanced by EtOH at concentrations that are reached with moderate, social EtOH consumption. Reproducible ethanol enhancements occur at 3 mM, a concentration six times lower than the legal blood-alcohol intoxication (driving) limit in most states (0.08% wt/vol or 17.4 mM). GABARs responsive to these low EtOH concentrations require the GABAR δ-subunit, which is thought to be associated exclusively with α 4 - and α 6 -subunits in vivo , and the β 3 -subunit, which has recently been shown to be essential for the in vivo anesthetic actions of etomidate and propofol. GABARs containing β 2 -instead of β 3 -subunits in α 4 βδ- and α 6 βδ-receptor combinations are almost 10 times less sensitive to EtOH, with threshold enhancement at 30 mM. GABARs containing γ 2 -instead of δ-subunits with α 4 β and α 6 β are three times less sensitive to EtOH, with threshold responses at 100 mM, a concentration not usually reached with social EtOH consumption. These combined findings suggest that “extrasynaptic” δ-subunit-containing GABARs, but not their “synaptic” γ-subunit-containing counterparts, are primary targets for EtOH.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
