2006-01-01 · Two glutamate receptor subtypes at the NMJ. Glutamate receptors containing either the DGluRIIA (left) or DGluRIIB (right) are physiologically different. The top two traces show single channel responses to the brief application of glutamate (upper line). While the current amplitude is the same, the IIB‐containing receptors desensitize more These include, but certainly are not limited to, the DA and glutamate receptor subtypes involved, the baseline activity-state of the neuron, the location of the receptors on pre- and/or postsynaptic elements, and endogenous concentrations of glutamate and DA. In our view a very important factor is receptor subtype. 1999). Both receptor subtypes are preferentially local-ized in the preterminal region of axons, where their ac-tivation attenuates glutamate release. mGlu3 receptors, however, are widely expressed on astrocytes, where their functional role is becoming increasingly important (see below). Group-III mGlu receptors include the subtypes 2017-11-01 · Overview of the two groups of glutamate receptors.

KW - Kainate. KW - Microdialysis 2019-02-10 · Most NMDA receptors include two GluN1 subunits and either two GluN2 subunits of the same or different subtypes, or two GluN1 subunits, plus a GluN2 and a GluN3 subunit (Khacho et al, 2015). The GluN2 subunit contains the binding site for glutamate, while the binding site for glycine is found on the GluN1 subunit. metabotropic glutamate receptors belong to the class C GPCRs, and they can be classified into eight subtypes divided into three groups based on their pharmacology, sequential homology and G protein coupling. Group I receptors (mGlu 1, mGlu 5) are preferentially coupled to Gαq, and are typically found postsynap-tically, Group II receptors (mGlu This requires a further understanding of the precise roles of glutamate receptors in the regulation of basal ganglia circuitry both in normal physiological and pathophysiological conditions, as well as the development of the more selective compounds for certain subtypes so that rational designs for combination therapy can be formulated.
