Project Description

Fast neuronal communication at synaptic contacts relies on neurotransmitter release from the presynaptic terminal and the majority of excitatory neurotransmission within the mammalian central nervous system is mediated by the neurotransmitter glutamate. Glutamate acts on a number of ligand gated ion channels often referred to as ’ionotropic’ receptors which when opened permit ion flux across the cell membrane and result in a change in neuronal excitability. One subtype of ionotropic glutamate receptor is the N-methyl-D-aspartate receptor (NMDAR) and these receptors play a number of roles in normal and abnormal processes within the central nervous system (CNS), ranging from learning and memory to excitotoxic neuronal cell death following stroke or brain trauma. The involvement of NMDARs in such a broad range of CNS processes and disorders has triggered a great deal of interest in understanding the molecular determinants of NMDAR function. This knowledge is not only required for teasing apart the complex mechanisms of receptor action but may also assist in the development of therapeutic strategies to combat the neurological damage induced by NMDAR overactivity.

NMDARs are heteromeric protein complexes made up of different types of subunit and my laboratory is interested in understanding how specific regions or ’functional’ domains within these receptor subunits can specify distinct pharmacological or functional properties. We are also interested in exploring the impact of NMDARs with altered pharmacological properties on neuronal function. The laboratory is a using variety of molecular biological, biochemical and functional methods to understand the roles played by these domains in receptor function and pharmacology.
