General description

NR1 (NMDA1or NMDAR1, also known as GRIN1) along with the NR2 subunit forms a heterodimer that make up the NMDA receptor. The NMDA receptor (NMDAR) is characterized as a ionotropic receptor for glutamate. As the name suggests, (NMDA (N-methyl D-aspartate) is an agonist for the receptor. A distinct characteristic of the NMDA receptor is that it is both ligand-gated and voltage-dependent based on its sensitivity to magnesium. Activated NMDA receptors result in the opening of an ion channel that is nonselective to cations. The result is the flow of Na+ and small amounts of Ca2+ ions into the cell and K+ out of the cell. Calcium flux by the NMDARs has been implicated in synaptic plasticity, a mechanism in the cell for learning and memory.

Painful peripheral neuropathy is a severe adverse effect of chemotherapeutic drugs such as paclitaxel (Taxol). The glutamate N-methyl-d-aspartate receptors (NMDARs) are critically involved in the synaptic plasticity associated with neuropathic pain.

Pathways and Biomarkers of Glutamatergic Synapse Flyer

Glutamate is an excitatory neurotransmitter found in the synaptic vesicles of glutamatergic synapses. The post-synaptic neurons in these synapses contain ionotropic and metabotropic glutamate receptors. Glutamate binds to AMPA (Ī±-amino-3-hydroxy-5- methylisoxazole-4-propionic acid) subtype glutamate receptors, leading to sodium influx into the post-synaptic cell and resulting in neuronal excitability and synaptic transmission. The NMDA (N-methyl-d-aspartate) subtype glutamate receptors, on the other hand, regulate synaptic plasticity, and can influence learning and memory. The metabotropic g-protein coupled mGluRs modulate downstream calcium signaling pathways and indirectly influence the synapseā€™s excitability. The synaptic architecture includes intracellular scaffolding proteins (PSD-95, GRIP), intercellular cell adhesion molecules (NCAMs, N-Cadherins), and a variety of signaling proteins (CaMKII/PKA, PP1/PP2B). Processes critical for synaptic transmission and plasticity are influenced by these molecules and their interactions. When the function of these molecules is disrupted, it leads to synaptic dysfunction and degeneration, and can contribute to dementia as seen in Alzheimerā€™s disease.
