At synapses, NMDARs contain GluN2A subunits;  23 Jan 2019 Metabotropic glutamate receptors are family C G-protein-coupled receptors.

Anti-NMDA receptor encephalitis manifests along a spectrum of psychosis, altered  Glutamatergic excitatory synaptic transmission; Ionotropic glutamate receptors; AMPA and NMDA receptors; Measuring kinetics of ligand-gated ion channels  Glutamate receptors transduce excitatory signals from glutamatergic presynaptic terminals to postsynaptic neurons. Glutamate receptors are also expressed by  N-methyl-D-Aspartate (NMDA)-Type Glutamate Receptor Autoantibody Disorders - Anti-NMDA-Receptor Encephalitis.

Mol. Cells Glutamate receptors are the most abundant type of excitatory neurotransmitter receptors in the mammalian forebrain. Glutamate receptors are responsible for the excitatory drive in neuronal networks, and are uniquely involved in activating downstream signaling cascades required for synaptic plasticity, learning, and memory. Glutamate signaling activates a family of receptors consisting of metabotropic glutamate receptors (mGluRs) and ionotropic glutamate receptors (iGluRs), both of which have been implicated in chronic disabling brain disorders such as Schizophrenia and neurodegenerative diseases like Alzheimer's, Parkinson's, and multiple sclerosis.

Vad är egentligen glutamat? Glutaminsyra är en aminosyra som förekommer naturligt i många råvaror.

Biochemical receptors for glutamate fall into three major classes, known as AMPA receptors, NMDA receptors, and metabotropic glutamate receptors. A fourth class, known as kainate receptors, are similar in many respects to AMPA receptors, but much less abundant. Many synapses use multiple types of glutamate receptors.
