Bicuculline as an antagonist of alpha2 glycine receptor.

细胞系/组织： HEK-293
Apart of classical action at GABA-A receptors, bicuculline methobromide (BIC) can be used as a tool to reveal presence of alpha2 glycine receptor (GlyR) subunit.In our work we transfected HEK cells with alpha2 and beta GlyR subunits to obtain heteromeric GlyRs. Application of glycine triggered a clear receptors response, but subsequent addition of BIC decreased response amplitude by >95% (see image). This confirmed expression of alpha2 subunits and their incorporation into active GlyRs.

Written by Ian Martin, Norman Bowery and Susan Dunn, this review provides a history of the GABA receptor, as well as discussing the structure and function of the various subtypes and the clinical potential of receptor modulators; compounds available from Tocris are listed.
Addiction Poster
The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.
