Species differences in the concentrations and distributions of opioid binding sites

Abstract

Binding at the mu, delta- and kappa-types of opioid binding sites was compared in homogenates from the brains of guinea-pig, rabbit, rat and two mouse strains, under conditions of selective labelling. Species differences were shown by two observations. Firstly, analysis of saturation curves in homogenates of brain from which the cerebellum had been removed showed that in guinea-pig brain the opioid binding sites consist of 24% mu-sites, 32% delta-sites and 44% kappa-sites. In contrast, in rabbit brain the corresponding values are 43% mu-sites, 19% delta-sites and 37% kappa-sites and in rat brain, 46% mu-sites, 42% delta-sites and 12% kappa-sites. In the brains of DBA/2 mice the opioid binding sites are comprised of 51% mu-sites, 29% delta-sites and 20% kappa-sites and in C57BL/10 mice, of 44% mu-sites, 35% delta-sites and 21% kappa-sites; these strain differences are due to significant differences in the concentrations of the mu-sites. Secondly, species differences were found when the binding of single concentrations of tritiated ligands (1 X KD value in whole brain) was determined at mu-, delta- and kappa-sites in six brain regions from guinea-pig, rat or rabbit.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The three opioid receptor types have distinct patterns of expression throughout the brain, with significant inter-species variability.

    “These three receptor types have distinct patterns of expression throughout the brain, and these patterns have significant inter-species variability (Khachaturian et al 1985; Robson et al 1985; Mansour et al 1987; Mansour et al 1988; Mansour et al 1994a; Mansour et al 1994b; Curran and Watson 1995; Resendez et al 2012).”

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.
