The Mechanism of Enantioselective Neurosteroid Actions on GABA_A Receptors

Biomolecules, 2023
The neurosteroid allopregnanolone (ALLO) and pregnanolone (PREG), are equally effective positive allosteric modulators (PAMs) of GABAA receptors. Interestingly, the PAM effects of ALLO are strongly enantioselective, whereas those of PREG are not.

New GABA amides activating GABA_A-receptors [PDF]

Beilstein Journal of Organic Chemistry, 2013
We have prepared a series of new and some literature-reported GABA-amides and determined their effect on the activation of GABAA-receptors expressed in CHO cells. Special attention was paid to the purification of the target compounds to remove even traces of GABA contaminations, which may arise from deprotection steps in the synthesis. GABA-amides were

Conditional gene deletion reveals functional redundancy of GABA_B receptors in peripheral nociceptors in vivo

Molecular Pain, 2009
Background γ-aminobutyric acid (GABA) is an important inhibitory neurotransmitter which mainly mediates its effects on neurons via ionotropic (GABAA) and metabotropic (GABAB) receptors.

Allosteric modulation of retinal GABA receptors by ascorbic acid [PDF]

, 2011
Ionotropic GABA receptors (GABAA and GABAC) belong to the Cys-loop receptor family of ligand-gated ion channels. GABAC receptors are highly expressed in the retina, mainly localized at the axon terminals of bipolar cells.

Anaesthetic impairment of immune function is mediated via GABA(A) receptors.

PLoS ONE, 2011
BackgroundGABA(A) receptors are members of the Cys-loop family of neurotransmitter receptors, proteins which are responsible for fast synaptic transmission, and are the site of action of wide range of drugs.

Insights into GABA receptor signalling in TM3 Leydig cells [PDF]

, 2005
gamma-Aminobutyric acid (GABA) is an emerging signalling molecule in endocrine organs, since it is produced by endocrine cells and acts via GABA(A) receptors in a paracrine/autocrine fashion.

Investigating the Role of Loop C Hydrophilic Residue 'T244' in the Binding Site of ρ1 GABAC Receptors via Site Mutation and Partial Agonism. [PDF]

PLoS ONE, 2016
The loop C hydrophilic residue, threonine 244 lines the orthosteric binding site of ρ1 GABAC receptors was studied by point mutation into serine, alanine and cysteine, and tested with GABA, some representative partial agonists and antagonists. Thr244 has

Stress and GABA_Areceptors [PDF]

Journal of Neurochemistry, 2010
J. Neurochem.(2010)112, 1115–1130.AbstractGABAAreceptors are sensitive to subtle changes in the environment in both early‐life and adulthood. These neurochemical responses to stress in adulthood are sex‐dependent. Acute stress induces rapid changes in GABAAreceptors in experimental animals, with the direction of the changes varying according to the sex

GABA-A and GABA-B Receptors in Filial Imprinting Linked With Opening and Closing of the Sensitive Period in Domestic Chicks (Gallus gallus domesticus)

Frontiers in Physiology, 2018
Filial imprinting of domestic chicks has a well-defined sensitive (critical) period lasting in the laboratory from hatching to day 3. It is a typical model to investigate the molecular mechanisms underlying memory formation in early learning. We recently

Multiple and plastic receptors mediate tonic GABAA receptor currents in the hippocampus [PDF]

, 2005
Persistent activation of GABAA receptors by extracellular GABA (tonic inhibition) plays a critical role in signal processing and network excitability in the brain.
