Abstract

Integrins comprise a large family of cell adhesion receptors that mediate diverse biological events through cell–cell and cell–extracellular matrix interactions. Recent studies have shown that several integrins are localized to synapses with suggested roles in synaptic plasticity and memory formation. We generated a postnatal forebrain and excitatory neuron-specific knock-out of β1-integrin in the mouse. Electrophysiological studies demonstrated that these mutants have impaired synaptic transmission through AMPA receptors and diminished NMDA receptor-dependent long-term potentiation. Despite the impairment in hippocampal synaptic transmission, the mutants displayed normal hippocampal-dependent spatial and contextual memory but were impaired in a hippocampal-dependent, nonmatching-to-place working memory task. These phenotypes parallel those observed in animals carrying knock-outs of the GluR1 (glutamate receptor subunit 1) subunit of the AMPA receptor. These observations suggest a new function of β1-integrins as regulators of synaptic glutamate receptor function and working memory.

  • β1 integrins are implicated in neuronal development and plasticity.

    “and have been firmly implicated in neuronal development and plasticity (Wiera et al. 2022; Chan et al. 2006).”

    From The Serine/Threonine Kinase <scp>NDR2</scp> Regulates Integrin Signaling, Synapse Formation, and Synaptic Plasticity in the Hippocampus (2025) · cites this paper as Chan et al. 2006

    The Abstract (page unavailable) reports diminished hippocampal long-term potentiation after postnatal β1-integrin knockout, supporting the plasticity part of the claim. The paper examines postnatal synaptic function, but the passages do not establish a role for β1-integrins in neuronal development. (LLM, conf=0.85)

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.
