Plasticity of GABAergic Inhibition

The document discussed the plasticity of δ-GABAARs, which are GABA receptors involved in tonic inhibition and are sensitive to neurosteroids but not benzodiazepines. It highlighted how changes in neurosteroid production, such as during pregnancy and the ovarian cycle, affect δ-GABAARs expression and consequently influence neuronal network functioning, including hippocampal excitability and γ oscillations. The study suggested that δ-GABAARs play a role in neurological and psychiatric disorders like epilepsy and postpartum depression. It proposed that targeting δ-GABAARs on specific neurons could offer therapeutic strategies, as these receptors have distinct subunit compositions on excitatory neurons versus interneurons.
