AMPA receptor trafficking at excitatory synapses

Open access
Bredt, David S, Nicoll, Roger A·2003·Neuron

Abstract

Excitatory synapses in the CNS release glutamate, which acts primarily on two sides of ionotropic receptors: AMPA receptors and NMDA receptors. AMPA receptors mediate the postsynaptic depolarization that initiates neuronal firing, whereas NMDA receptors initiate synaptic plasticity. Recent studies have emphasized that distinct mechanisms control synaptic expression of these two receptor classes. Whereas NMDA receptor proteins are relatively fixed, AMPA receptors cycle synaptic membranes on and off. A large family of interacting proteins regulates AMPA receptor turnover at synapses and thereby influences synaptic strength. Furthermore, neuronal activity controls synaptic AMPA receptor trafficking, and this dynamic process plays a key role in the synaptic plasticity that is thought to underlie aspects of learning and memory.

  • Controlled addition and removal of AMPA-type glutamate receptors from the postsynaptic density underlies changes in synaptic strength during learning and memory formation.

    “Controlled addition and removal of AMPA-type glutamate receptors from the postsynaptic density is believed to underlie the changes in synaptic strength during learning and memory formation (Malinow and Malenka, 2002; Sheng and Kim, 2002; Bredt and Nicoll, 2003; Collingridge et al., 2004).”

  • NMDAR-dependent LTD involves clathrin-dependent rapid endocytosis of AMPA receptors (AMPARs).

    “NMDA receptor (NMDAR)–dependent LTD, an extensively studied form of LTD, involves a rise in postsynaptic Ca2+ concentration, activation of a serine-threonine protein phosphatase cascade, and clathrin-dependent rapid endocytosis of AMPA receptors (AMPARs) [1]–[10].”

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.
