Densities of dopamine D2 receptors are reduced in CNS regions of alcohol-preferring P rats
Abstract
The densities of dopamine D2 recognition sites labelled with [3H]sulpiride were determined in the caudate-putamen, nucleus accumbens (medial and lateral portions), olfactory tubercle, substantia nigra (pars reticulata and pars compacta), and ventral tegmental area (VTA) of alcohol-naive, selectively bred P (N = 7) and NP (N = 7) rats using quantitative autoradiography. The binding of [3H]sulpiride was 20-25% lower (P < 0.05) in the caudate-putamen, medial and lateral nucleus accumbens, and VTA of the P compared with the NP rats. No significant differences were observed between the P and NP rats in the olfactory tubercle or substantia nigra. [3H]Sulpiride binding, using standard membrane preparations, established with Scatchard analysis that the difference in the densities of D2 recognition sites in the caudate-putamen between the P and NP rats was due to lower Bmax values for the P line. The results indicate that the number of dopamine D2 receptor sites is lower in several central nervous system regions of the P rats compared to NP rats.

“Strikingly, animals with low D2 receptor levels in the striatum prior to drug or alcohol exposure subsequently display greater cocaine or alcohol self-administration (Czoty et al., 2004; Dalley et al., 2007; McBride et al., 1993; Morgan et al., 2002; Nader et al., 2006; Stefanini et al., 1992).”

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.
