Distribution of parvalbumin-containing neurons and lectin-binding perineuronal nets in the rat basal forebrain

Brauer, Kurt, Ha¨rtig, Wolfgang, Bigl, Volker, Bru¨ckner, Gert·1993·Brain Research

Abstract

In sections of rat brain treated for Wisteria floribunda agglutinin (WFA) labelling the occurrence of parvalbumin (PARV)-, calbindin (CALB)- or choline acetyltransferase (ChAT) immunoreactivity was analyzed in the basal forebrain using dual-peroxidase and double-fluorescence methods. Only PARV-immunoreactive (-ir) neurons were surrounded by WFA-labelled, i.e. N-acetylgalactosamine-containing, perineuronal lattice-like structures known as perineuronal nets. The distribution of these nets and PARV-ir cells in the rat basal forebrain was documented to obtain detailed data on their co-existence. A remarkable diversity in distribution of both markers was observed, as PARV-ir neurons are only associated with nets in the medial septal nucleus, the nuclei of the diagonal band and the magnocellular preoptic nucleus, but not in the ventral pallidum or the substantia innominata/nucleus basalis complex. These differences in the neuronal microenvironment may reflect system-related specializations of neurons within the basal forebrain nuclei.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • A large population of WFA-labeled PNNs ensheaths fast-firing inhibitory interneurons expressing parvalbumin and Kv3.1b.

    “Several studies in rodent, human and non-human primates have shown that a large population of WFA-labeled PNNs ensheaths fast-firing inhibitory interneurons expressing the calcium binding protein parvalbumin (PVB) and Kv3.1b, a subunit of voltage gated potassium channels typically expressed in fast-firing neurons (Brauer et al., 1993; Hartig et al., 1995; Morris and Henderson, 2000; Pantazopoulos”
  • PNN-bearing neurons are predominantly GABAergic, including but not restricted to those expressing parvalbumin and somatostatin.

    “As discussed, these are predominantly represented by GABAergic neurons, including, but not restricted to, those expressing PVB and somatostatin (Adams et al., 2001; Brauer et al., 1993; Bruckner et al., 1993; Hartig et al., 1995; Hartig et al., 2001; Haunso et al., 1999; Morris and Henderson, 2000; Pantazopoulos et al., 2006; Wintergerst et al., 1996) (Pantazopoulos et al., unpublished”

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.
