Homocarnosine and carnosine have been identified in bovine brain extracts which are effective in protecting mice against infections by Staphylococcus aureus. These peptides, as well as l-1-methylhistidine, beta-alanine, gamma-aminobutyric acid, delta-aminovaleric acid, epsilon-aminocaproic acid, 1-aminomethylcyclohexane-4-carboxylic acid, and anserine, were tested as prophylactic agents against...
The neurotransmitter gamma-aminobutyric acid (GABA) mediates inhibitory signaling in the brain via stimulation of both GABA(A) receptors (GABA(A)R), which are chloride-permeant ion channels, and GABA(B) receptors (GABA(B)R), which signal through coupling to G proteins. Here we report physical interactions between these two different classes of GABA receptor. Association of the GABA(B) receptor ...
The purpose of the present study was to study gamma-aminobutyric acid (GABA)-A receptor function in alcohol-dependent subjects during withdrawal, using the benzodiazepine antagonist flumazenil. In particular, we wanted to examine the hypotheses that an endogenous inverse agonist ligand at the GABA-A benzodiazepine receptor (GBzR) is active during withdrawal (in which case flumazenil should be a...
A link between the circadian rhythm and the function of Cl(-)-permeable gamma-aminobutyric acid (GABA) type A (GABA(A)) receptors on suprachiasmatic nucleus (SCN) neurons was studied by measuring intracellular activity of Cl(-) (aCl) at different times during a circadian cycle in SCN neurons acutely dissociated from rat brains. To measure aCl, the voltage-clamp mode of the gramicidin-perforated...
