Web29 May 2024 · Glutamate receptors are essential ligand-gated ion channels in the central nervous system that mediate excitatory synaptic transmission in response to the release of glutamate from presynaptic terminals. The structural and biophysical basis underlying the function of these receptors has been studied for decades by a wide range of approaches. WebThe glutamate receptor ion channels (iGluRs) are abundantly expressed in the brain and spinal cord and mediate responses at the vast majority of excitatory synapses. Mammalian iGluRs are encoded by 18 genes which assemble to form four major families, the AMPA, kainate, NMDA and delta receptors.
