Abstract

SUMMARY Although the extracellular matrix plays an important role in regulating use-dependent synaptic plasticity, the underlying molecular mechanisms are poorly understood. Here we examined the synaptic function of hyaluronic acid (HA), a major component of the extracellular matrix. Enzymatic removal of HA with hyaluronidase reduced nifedipine-sensitive whole-cell Ca2+ currents, decreased Ca2+ transients mediated by L-type voltage-dependent Ca2+ channels (L-VDCCs) in postsynaptic dendritic shafts and spines, and abolished an L-VDCC-dependent component of long-term potentiation (LTP) at the CA3-CA1 synapses in the hippocampus. Adding exogenous HA, either by bath perfusion or via local delivery near recorded synapses, completely rescued this LTP component. In a heterologous expression system, exogenous HA rapidly increased currents mediated by Cav1.2, but not Cav1.3, subunit-containing L-VDCCs, whereas intrahippocampal injection of hyaluronidase impaired contextual fear conditioning. Our observations unveil a previously unrecognized mechanism by which the perisynaptic extracellular matrix influences use-dependent synaptic plasticity through regulation of dendritic Ca2+ channels.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Digestion of hyaluronan reduces fear memory retrieval.

    “The effectiveness of ChABC implicates CSPGs, but digestion of hyaluronan also reduces fear memory retrieval [61].”

    From The extracellular matrix and perineuronal nets in memory (2022) · cites this paper as [61]

    The Results section reports less freezing in the conditioned context after pretraining hyaluronidase injection, consistent with impaired contextual fear memory. But it says the effect could reflect impaired formation or retrieval; the Discussion adds that acquisition, consolidation, or retrieval may be involved. The paper does not establish a specific reduction in retrieval. (LLM, conf=0.88)

  • Most studies in the hippocampal CA1 region show that PNN degradation or attenuation decreases long-term potentiation (LTP).

    “Most studies in the hippocampal CA1 region show that PNN degradation or attenuation decreases long-term potentiation (LTP)[60–65].”

    From The extracellular matrix and perineuronal nets in memory (2022) · cites this paper as [61]

  • Perineuronal nets (PNN) regulate synaptic plasticity and rewiring of the network of interneurons.

    “Importantly, PNN regulate the synaptic plasticity (Kochlamazashvili et al., 2010) and rewiring the network (Pollock et al., 2014) of the interneurons (Wen et al., 2018).”

  • These functions underlie the role of the adult ECM in neuronal excitability, receptor desensitization, long-term potentiation and long-term depression.

    “Overall, these functions underlie the role of the adult ECM to neuronal excitability, receptor desensitization, long-term potentiation and long-term depression.59, 87, 88, 90, 91, 92, 93”

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.
