Abstract

Background Postmortem studies have provided evidence for abnormalities of the gamma-aminobutyric acid (GABA)-ergic system in schizophrenia, including deficits of GABA-containing interneurons. The calcium-binding proteins parvalbumin, calbindin, and calretinin can be used as markers for specific subpopulations of cortical GABAergic interneurons.Methods Following our previous observation of a reduction in the density of parvalbumin- but not calretinin-immunoreactive cells in the prefrontal cortex (Brodmann area 10) in schizophrenia, we have quantified the laminar density of neurons immunoreactive for the calcium-binding proteins parvalbumin, calbindin, and calretinin in a further prefrontal cortical region (Brodmann area 9) in patients with schizophrenia, bipolar disorder, major depression, and in matched control subjects (each group n = 15).Results Initial statistical analysis revealed reductions in the total cortical density of parvalbumin- and calbindin- but not calretinin-immunoreactive neurons in schizophrenia relative to control subjects. Further analysis comparing individual laminar densities between groups indicated that, following correction for multiple comparisons, only a reduction in calbindin-immunoreactive neurons in cortical layer II in the schizophrenic group attained statistical significance.Conclusions These findings suggest that deficits of specific GABAergic neurons, defined by the presence of calcium-binding proteins, are present in schizophrenia. Trends toward similar reductions are observed in bipolar disorder.

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.
