The extracellular matrix and synapses

Dityatev, Alexander, Schachner, Melitta·2006·Cell and Tissue Research

Abstract

Extracellular matrix (ECM) molecules, derived from both neurons and glial cells, are secreted and accumulate in the extracellular space to regulate various aspects of pre- and postsynaptic differentiation, the maturation of synapses, and their plasticity. The emerging mechanisms comprise interactions of agrin, integrin ligands, and reelin, with their cognate cell-surface receptors being coupled to tyrosine kinase activities. These may induce the clustering of postsynaptic receptors and changes in their composition and function. Furthermore, direct interactions of laminins, neuronal pentraxins, and tenascin-R with voltage-gated Ca(2+) channels, alpha-amino-3-hydroxy-5-methylisoxazole-4-proprionic acid (AMPA), and gamma-aminobutyric acid(B) (GABA(B)) receptors, respectively, shape the organization and function of different subsets of synapses. Some of these mechanisms significantly contribute to the induction of long-term potentiation in excitatory synapses, either by the regulation of Ca(2+) entry via N-methyl-D-aspartate receptors or L-type Ca(2+) channels, or by the control of GABAergic inhibition.

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.
