The pharmacology and physiology of GABA-C receptors

Funded Activity Summary

GABA is one of the most important chemicals in the brain. GABA and its associated receptors (GABA receptors) work together to keep the balance between neuronal excitation and inhibition which is required for normal brain function. There are three types of GABA receptors called GABA-A, GABA-B and GABA-C receptors. Chemicals acting at these receptors may be therapeutically useful in treating neurological probles such as epilepsy, anxiety, depression and memory-related disorders associated with Alzheimer's disease and schizophrenia. GABA-A and GABA-C receptors are members of the ligand-gated ion channel super family in which the ion channel forms an intergral and central part of the receptor. In response to GABA, the channel opens and chloride ions flow through the channel. This causes an inhibitory action i.e. the cell reduces its rate of firing. This project aims to study GABA-C receptors by investigating what proteins make up the ion channel, by studying the actions of a range of chemicals that have specific effects at these receptors and by identifying amino acids that are important for normal channel function. New chemicals identified in our studies will provide leads for the design and development of new therapeutic agents acting on the brain.
