Abstract
Both GABA-A and nAChRs are of pentameric structure, where 5 out of a set of 19 (GABA-A) or 17 (nAChR) subunits assemble to form different receptors subtypes. The functional properties of these subtypes are primarily determined by their subunit composition, and knowledge of the molecular structure is thus crucial for an understanding of receptor function in health and disease. Different receptor subtypes also display different drug binding sites, and the identification of subtype selective compounds is of great interest for both GABA-A and nACh receptors.
Techniques
- Cultivation of primary neurons (of Hippocampus or superior cervical ganglion)
- Cultivation and Transfection of HEK-293-cells
- Radioligand binding assays
- drug induced neurotransmitter release out of synaptosomes, slices and cell cultures
- molecular biology (cloning of receptor mutants)
