Ca2+-permeable AMPA receptors in synaptic plasticity and neuronal death

Liu, Siqiong June, Zukin, R. Suzanne·2007·Trends in Neurosciences

Abstract

AMPA receptors mediate fast synaptic transmission at excitatory synapses in the CNS and are crucial during neuronal development, synaptic plasticity and structural remodeling. AMPA receptors lacking GluR2 subunits are permeable to Ca(2+) and Zn(2+). Ca(2+) permeation through AMPA receptors is crucial in several forms of synaptic plasticity and cell death associated with neurological diseases and disorders. The subunit composition and Ca(2+) permeability of AMPA receptors are not static, but they are dynamically remodeled in a cell- and synapse-specific manner during development and in response to neuronal activity, sensory experience and neuronal insults. Exciting new research shows that these changes arise not only because of regulated expression of the AMPA receptor subunit GluR2, but also as a consequence of RNA editing, receptor trafficking and dendritic protein synthesis. This article reviews new insights into the role of Ca(2+)-permeable AMPA receptors in neuronal function and survival.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • AMPARs that contain GluA2 are calcium-impermeable.

    “This design renders AM-PARs that contain GluA2 calcium-impermeable (Liu and Zukin 2007).”
  • There are forms of synaptic potentiation that are expressed by an exchange of GluA2-containing AMPARs in the synapse for GluA2-lacking AMPARs.

    “In addition, there are also forms of synaptic potentiation that are expressed by an exchange of GluA2-containing AMPARs in the synapse for GluA2-lacking AMPARs (Liu and Zukin 2007).”

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.
