Description:
The Ernst group works on GABA-A receptors with focus on mode of action and subtype specific allosteric ligands (such as subtype selective benzodiazepines), and on the role of these receptors in diverse pathologies.
Ongoing collaborations include the characterization of GABR variants in neuropsychiatric conditions such as epilepsy (with Martin Krenn), the development of tool compounds for the in vitro, ex vivo and in vivo study of GABA-A receptor function within the FWF funded W1232 program, and the study of GABA-A receptor mediated toxicology in the EU/ IMI2 funded NeuroDeRisk program.
