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.
GABA-A Gamma2 neurons express the GABA-A receptor gamma2 subunit (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. [1]
