Glua3 (Ampa3) Neurons is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
Neurons expressing the AMPA receptor subunit GluA3 (encoded by the GRIA3 gene) represent a critical population of excitatory neurons in the central nervous system. AMPA receptors (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors) are ionotropic glutamate receptors that mediate the majority of fast excitatory synaptic transmission in the brain. The GluA3 subunit, along with other AMPA subunits (GluA1-4), determines the pharmacological and biophysical properties of these receptors. [@ampa2020]
