Vicia villosa lectin-positive neurones in human cerebral cortex. Loss in Alzheimer-type dementia

Kobayashi, K., Emson, P.C., Mountjoy, C.Q.·1989·Brain Research

Abstract

Frontal and temporal sections of 4 normal human brains and 3 brains from patients with a diagnosis of Alzheimer-type dementia (ATD) were stained with Vicia villosa lectin conjugated to biotin to localize glycoproteins containing terminal N-acetylgalactosamine. These lectin binding sites were localized at the surface of a population of non-pyramidal interneurones. Examination of the co-existence of calbindin D28K or parvalbumin (PVA) with the lectin-binding material revealed that in the human cerebral cortex the lectin labelled only the PVA-immunoreactive neurones. Cell counts of the number of lectin-staining cells revealed that these cells are lost in ATD. The few remaining lectin-staining cells in ATD are shrunken and showed reduced expression of the lectin-staining material.

Recomputing p-values needs the paper’s full text.

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?

  • Studies using VVA and WFA lectin staining of PNN CS-GAGs showed up to 70% reductions in abundance of PNN CS glycan attachments in postmortem AD brain tissue.

    “Studies using Vicia villosa agglutinin (VVA) and Wisteria floribunda agglutinin (WFA) lectin staining of PNN CS-GAGs showed up to 70% reductions in the abundance of PNN CS glycan attachments in postmortem AD brain tissue (Kobayashi et al. 1989; Baig et al. 2005).”

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.
