Abstract

An interneuron alteration has been proposed as a source for the modified balance of excitation / inhibition in the cerebral cortex in autism. We previously demonstrated a decreased number of parvalbumin (PV)-expressing interneurons in prefrontal cortex in autism. PV-expressing interneurons include chandelier (Ch) and basket (Bsk) cells. We asked whether the decreased PV+ interneurons affected both Ch cells and Bsk cells in autism. The lack of single markers to specifically label Ch cells or Bsk cells presented an obstacle for addressing this question. We devised a method to discern between PV-Ch and PV-Bsk cells based on the differential expression of Vicia villosa lectin (VVA). VVA binds to N-acetylgalactosamine, that is present in the perineuronal net surrounding some cell types where it plays a role in intercellular communication. N-acetylgalactosamine is present in the perineuronal net surrounding Bsk but not Ch cells. We found that the number of Ch cells is consistently decreased in the prefrontal cortex of autistic (n = 10) when compared with control (n = 10) cases, while the number of Bsk cells is not as severely affected. This finding expand our understanding of GABAergic system functioning in the human cerebral cortex in autism, which will impact translational research directed towards providing better treatment paradigms for individuals with autism.

  • In ASD, the number of neurons (but also their size), specifically the chandelier cells, basket cells and other parvalbumin-expressing interneurons, is decreased in the PFC.

    “The number of neurons (but also their size), specifically the chandelier cells, basket cells and other parvalbumin-expressing interneurons, is decreased in the PFC [369–371].”

    From Development of prefrontal cortex (2022) · cites this paper as [369]

    The Results (p. 7) report fewer chandelier cells in autistic prefrontal cortex and a possible mild decrease in basket cells in some areas; the Introduction (p. 2) reports an earlier finding of fewer PV-expressing interneurons. The paper does not report that these neurons are smaller, and it does not establish a general decrease in basket cells throughout the PFC. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • The number of parvalbumin-immunoreactive interneurons, but not calbindin- or calretinin-expressing ones, is decreased in the medial PFC in ASD, and this decrease is due to fewer chandelier interneurons.

    “The number of parvalbumin-immunoreactive interneurons, but not those expressing calbindin or calretinin, is decreased in the medial PFC [148], which was recently confirmed to be due to fewer chandelier interneurons [12].”

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.
