Abstract
The GABAA (γ-aminobutyric acid-A) receptor γ2 subunit subtype is functionally integral part of the benzodiazepine binding site of the GABAA receptor complex, important for benzodiazepine pharmacology. We have evaluated the possibility of specifically reducing benzodiazepine receptor binding properties in vivo using phosphorothioate antisense oligodeoxynucleotides to inhibit the expression of GABAA receptor γ2 subinit subtype. Intracerebroventricular infusions of an antisense oligonucleotide reduced benzodiazepine receptor radioligand binding by 9–15% in specific rat brain regions.
