General description

The neurotransmitter GABA (gamma-aminobutyric acid) binds to specific transmembrane receptors in the plasma membrane of both pre- and postsynaptic neurons. Three general classes of GABA receptors are known: GABAA and GABAC (ionotropic) receptors and GABAB (metabotropic) receptors. The GABAA (gamma-Aminobutyric Acid type A) receptor is a multiprotein complex that acts as a ligand-gated chloride channel. These receptors are hetero-oligomers, for which 6 subunits are currently known (a, b, g, d, e and r). There are at least 6 different isoforms of the alpha subunit, and receptor subunit expression varies during development. Increased alpha1 subunit assembly in postsynaptic receptors of cerebellar inhibitory synapses is responsible for the fast inhibitory synaptic currents observed during postnatal development. Additionally, alpha1-containing GABAA receptors are important in regulating the reinforcing properties of alcohol, and expression of the alpha1 subunit increases upon chronic exposure to alcohol, making it a potential therapeutic target for alcohol dependency.

Although neuronal activity can be modulated using a variety of techniques, there are currently few methods for controlling neuronal connectivity. We introduce a tool (GFE3) that mediates the fast, specific and reversible elimination of inhibitory synaptic inputs onto genetically determined

Tonic inhibition mediated by extrasynaptic GABA(A) receptors (GABARs) sensing ambient levels of GABA can profoundly alter the membrane input resistance to affect cellular excitability. Therefore, regulation of tonic inhibition is an attractive mechanism to control the levels of cortical firing.
