iGluR

Ionotropic glutamate receptors

iGluR (ionotropic glutamate receptor) is a ligand-gated ion channel that is activated by the neurotransmitter glutamate. iGluR are integral membrane proteins compose of four large subunits that form a central ion channel pore. Sequence similarity among all known glutamate receptor subunits, including the AMPA, kainate, NMDA, and δ receptors.

AMPA receptors are the main charge carriers during basal transmission, permitting influx of sodium ions to depolarise the postsynaptic membrane. NMDA receptors are blocked by magnesium ions and therefore only permit ion flux following prior depolarisation. This enables them to act as coincidence detectors for synaptic plasticity. Calcium influx through NMDA receptors leads to persistent modifications in the strength of synaptic transmission.

    Corticosterone
    Agonist 99.76%
    Corticosterone (17-Deoxycortisol) is an orally active and adrenal cortex-produced glucocorticoid, which plays an important role in regulating neuronal functions of the limbic system (including hippocampus, prefrontal cortex, and amygdala). Corticosterone increases the Rab-mediated AMPAR membrane traffic via SGK-induced phosphorylation of GDI. Corticosterone also interferes with the maturation of dendritic cells and shows a good immunosuppressive effect.
