Abstract

Mapping of multiple receptors of neurotransmitters provides insight into the spatial distribution of neurotransmission-relevant molecules in the cerebral cortex. During development, lack of reelin leads to impaired migration, disturbed lamination of the hippocampus and inverted neocortical layering. In the adult, reelin may regulate synaptic plasticity by modulating neurotransmitter receptor function. Using quantitative in vitro receptor autoradiography, different receptors, in particular, the binding site densities and laminar distribution of various glutamate, GABA, muscarinic and nicotinic acetylcholine, serotonin, dopamine and adenosine receptors, were analyzed in cortical and subcortical structures of reeler and wild-type brains. Differential changes in the laminar distribution, maximum binding capacity (B (max)) and regional density of neurotransmitter receptors were found in the reeler brain. A decrease of whole brain B (max) was found for adenosine A(1) and GABA(A) receptors. In the forebrain, several binding sites were differentially up- or down-regulated (kainate, A(1), benzodiazepine, 5-HT(1), M(2), α(1) and α(2)). In the hippocampus, a significant decrease of GABA(B), 5-HT(1) and A'₁ receptors were observed. The density of M(2) receptors increased, while other receptors remained unchanged. In the neocortex, some receptors demonstrated an obviously inverted laminar distribution (AMPA, kainate, NMDA, GABA(B), 5-HT(1), M(1), M(3), nAch), while the distribution of others (A(1), GABA(A), benzodiazepine, 5-HT(2), muscarinic M(2), adrenergic α(1), α(2)) seemed to be less affected. Thus, the laminar receptor distribution is modulated by the developmental impairment and suggests and reflects partially the laminar inversion in reeler mice.

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?

  • Reeler heterozygous mice with reduced reelin show decreased GAD67 and fewer GABAA and GABAB receptors in whole brain and hippocampus.

    “Reeler heterozygous mice, which are haploinsufficient for reelin, exhibit decreased GAD 67 [138] and reduced GABAA and GABAB receptors in the whole brain and hippocampus, respectively [139].”

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.
