General description
An excitatory amino acid neurotransmitter. Selective agonist of the glutamate receptor that regulates Ca2+ channels. Important in long-term potentiation, ischemia, and epilepsy. NMDA receptors are involved in the "fine tuning" of synaptic connections in the developing brain. Chronic treatment with NMDA produces structural changes in synaptic morphology. Over-excitation of NMDA receptors causes neuronal degeneration and cell death.

The degeneration of retinal ganglion cells (RGCs) leads to irreversible vision loss in a variety of pathological states. Here, we describe a protocol to evaluate the role of a gene in protecting mouse RGCs when they sustain injuries from excitotoxicity
Related Content
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 (α-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 synapse’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 Alzheimer’s disease.
