Wisteria floribunda agglutinin-labelled nets surround parvalbumin-containing neurons

Härtig, Wolfgang, Brauer, Kurt, Brückner, Gert·1992·NeuroReport

Abstract

Net-like structures surrounding several types of neurones contain glycoconjugates which are detectable by lectins specific for N-acetylgalactosamine. Wisteria floribunda agglutinin (WFA) was introduced as a further marker for the visualization of such perineuronal nets, which were also revealed in regions of the rat brain where these structures could not be clearly demonstrated using other lectins. The WFA-labelled perineuronal nets resembled in detail those which could be visualized using Vicia villosa agglutinin, colloidal iron or hyaluronectin as markers. Furthermore, WFA-stained perineuronal net components appeared to be similar to proteoglycan-immunoreactive structures. Dual-peroxidase experiments and fluorescence double labelling demonstrated that WFA-binding structures frequently ensheath GABAergic neurons containing the calcium-binding protein parvalbumin in the areas investigated.

  • PNNs are found primarily around fast-spiking, parvalbumin (PV)-containing GABAergic interneurons in many brain regions, but not all regions.

    “PNNs are found primarily around fast--spiking, parvalbumin (PV)--containing GABAergic interneurons in many brain regions (Hartig et al., 1992;Schuppel et al., 2002;Dityatev et al., 2007), but not all regions (e.g., cerebellum; see below).”

    From Casting a Wide Net: Role of Perineuronal Nets in Neural Plasticity (2016) · cites this paper as Hartig et al., 1992

  • PNNs surround inhibitory fast spiking parvalbumin-positive GABAergic interneurons and are also associated with excitatory pyramidal neurons in the cerebral cortex.

    “PNNs surround inhibitory fast spiking parvalbumin-positive GABAergic interneurons12–14, but are also associated with further subpopulations, for example excitatory pyramidal neurons in the cerebral cortex15,16.”
  • PNs frequently surround neurons containing parvalbumin, which are fast-firing GABAergic neurons co-expressing the voltage-gated potassium channel Kv3.1b.

    “PNs frequently surround neurons containing parvalbumin (Kosaka and Heizmann, 1989; Härtig et al., 1992), known as a marker for fast-firing GABAergic neurons co-expressing the voltage-gated potassium channel Kv3.1b (Härtig et al., 1999).”
  • The majority of neurons surrounded by perineuronal nets are parvalbumin-expressing GABAergic interneurons.

    “Strikingly, the majority of neurons surrounded by perineuronal nets are parvalbumin-expressing GABAergic interneurons [159]”

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.
