Perineuronal nets: past and present

Celio, Marco R, Spreafico, Roberto, De Biasi, Silvia, Vitellaro-Zuccarello, Laura·1998·Trends in Neurosciences

Abstract

Golgi ranked the peripheral reticulum--which adheres intimately to nerve cell surfaces--alongside the intracellular reticulum, or Golgi apparatus,which immortalized his name. At first dismissed as an artefact of capricious staining techniques, this peripheral reticulum, or perineuronal net, is now recognized as a genuine entity in neurocytology. It represents a complex of extracellular matrix molecules interposed between the meshwork of glial processes, from which they are indistinguishable, and nerve-cell surfaces. In no other branch of neuroscience has the waxing and waning of interest in any morphological entity been so pronounced as in the case of the perineuronal net. This review traces the history of this enigmatic structure from its conception to the present time, brings to light the keen observational powers of morphologists at the turn of the century and reveals how their sagacious forethought anticipated current thinking on the role of perineuronal nets.

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?

  • PNNs play key roles in neural development, synaptogenesis, neuroprotection, and experience-dependent synaptic plasticity.

    “As such, PNNs play key roles in neural development, synaptogenesis, neuroprotection, and experience-dependent synaptic plasticity (Celio et al., 1998;Dityatev and Schachner, 2003;McRae and Porter, 2012;Soleman et al., 2013;Suttkus et al., 2016).”

  • PNNs tightly interdigitate with synaptic contacts on the soma and proximal dendrites of neurons.

    “the unique, lattice--like structures that wrap around specific neurons in the brain and spinal cord called perineuronal nets (PNNs) that tightly interdigitate with synaptic contacts on the soma and proximal dendrites of neurons (Celio et al., 1998;Deepa et al., 2006;Soleman et al., 2013).”

    From Casting a Wide Net: Role of Perineuronal Nets in Neural Plasticity (2016) · cites this paper as Celio et al., 1998

  • PNNs exclusively enwrap the soma and most proximal segments of dendrites.

    “It has to be taken also into account that PNNs exclusively enwrap the soma and most proximal segments of dendrites (Celio et al., 1998;Fawcett et al., 2019)”
  • Perineuronal nets are specialized assemblies of extracellular matrix proteins that ensheath neurons and proximal dendrites.

    “Perineuronal nets are specialized assemblies of ECM proteins which ensheath neurons and proximal dendrites (Celio et al., 1998).”
  • PNNs are specialized aggregates of extracellular matrix molecules surrounding the somata, dendrites, and proximal axon segment of distinct neuronal populations.

    “Perineuronal nets (PNNs), first described by Camillo Golgi in 1898, are specialized aggregates of extracellular matrix (ECM) molecules surrounding the somata, dendrites and proximal axon segment of distinct neuronal populations (Fig. 1) (Brauer et al., 1993; Celio et al., 1998; Golgi, 1898; Kwok et al., 2011; Seeger et al., 1994; Spreafico et al., 1999; Vitellaro-Zuccarello et al., 1998).”

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.
