Glucocorticoid receptor

Corticosterone, via SGK phosphorylation of GDI at Ser-213, increases the formation of GDI-Rab4 complex, facilitating the functional cycle of Rab4 and Rab4-mediated recycling of AMPARs to the synaptic membrane. It enhances AMPAR-mediated miniature excitatory postsynaptic current (mEPSC) amplitude and surface expression of GluR1 and GluR2 subunits in hippocampal neurons, increases the surface mobility and synaptic content of AMPAR GluR2 subunits, and enhances L-type calcium currents in CA1 pyramidal neurons. Corticosterone operates through mineralocorticoid receptors and glucocorticoid receptors, both of which belong to the family of nuclear receptors that bind to response elements in the DNA, thus modifying the activity of responsive genes.

Corticosterone plays an important role in regulating neuronal functions of the limbic system. After stress, the level of stress hormones such as corticosterone is markedly increased. Corticosterone exerts a time- and region-specific action on cellular physiology of limbic neurons.
