Gaba A Gamma2 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
GABA-A Gamma2 neurons express the [GABA-A receptor](/mechanisms/gabaergic-signaling) gamma2 subunit ([GABRG2](/genes/gabrg2)), a critical component of most synaptic GABA-A receptors. The gamma2 subunit is essential for receptor clustering at postsynaptic sites, synaptic localization, and benzodiazepine sensitivity. GABA-A γ2-containing receptors mediate the majority of fast inhibitory synaptic transmission in the brain and are crucial for maintaining excitation-inhibition balance. [@sieghart2022]
