The stress hormone corticosterone conditions AMPAR surface trafficking and synaptic potentiation
&
Abstract
Corticosterone facilitates hippocampal glutamate transmission, but the cellular pathways by which AMPA receptor (AMPAR) signaling is adjusted remain elusive. Single quantum-dot imaging in live rat hippocampal neurons revealed that corticosterone triggers, via distinct corticosteroid receptors, time-dependent increases in GluR2-AMPAR surface mobility and synaptic surface GluR2 content.
