Abstract

The laminar cortical distribution of the [125I]alpha-bungarotoxin, [3H]cytisine and [3H]epibatidine nicotinic acetylcholine receptor ligands was investigated by quantitative autoradiography in autopsy tissue from the cingulate, orbitofrontal and temporal cortices of control and schizophrenia subjects matched for age and smoking history. Different laminar binding patterns were observed for the various nicotinic ligands both in schizophrenic and control brains. [125I]alpha-Bungarotoxin binding was distributed homogeneously across all cortical layers in all three brain regions, with highest binding densities in the cingulate cortex. [3H]Cytisine and [3H]epibatidine binding varied across the cortical ribbon, with high binding in layers I, III, V and VI, within the three cortical regions. A significantly reduced [125I] alpha-bungarotoxin binding (-54%) was observed in the cingulate cortex of schizophrenia subjects, in comparison with normal individuals who smoked tobacco. In the same brain region also a significantly higher [3H]cytisine binding (48-77%) was observed in nearly all layers, except for layer I of the schizophrenia subjects, when compared to normal individuals with a history of tobacco use. No significant changes in [3H]epibatidine binding was observed within the individual cortical layers between control subjects and patients with schizophrenia, but when calculated as a whole region (i.e. measurements performed across the whole cortical ribbon), the temporal cortex showed a significant increase in [3H]epibatidine binding in schizophrenia subjects compared to control subjects. The results suggest opposite changes of the alpha4beta2 and alpha7 nicotinic receptor subtypes in the cingulate cortex of patients with schizophrenia which might reflect involvement of two different nicotinic receptor mechanisms in schizophrenia brain.

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.
