Research project(s)
The neurobiology of plant parasitic nematodes.
Genetic differences have been identified in individuals with autism and schizophrenia. Here we are using the model organism C. elegans to investigate how these genetic differences bring about changes in the function of neural circuits.
Structural/functional studies of the ligand binding domains of nicotinic acetylcholine receptors.
Bioinformatic identification and physiological analysis of ethanol-related genes in C. elegans - Dormant
Using the model organism, Caenorhabditis elegans, to investigate the broad molecular, cellular and systems level impacts of acute and chronic ethanol treatment.
Changes in the pattern of behaviour with increasing alcohol intake in humans reflect its complex effects on the brain.
Mammalian Neurodegeneration
ME7 Synaptopathy model: a protein aggregation disease to model Alzheimer’s disease and other chronic neurodegeneration
We are using a mouse model of prion disease which like Alzheimer’s is associated with the extracellular deposition of misfolded protein and an accompanying loss of synapses.
Metabotropic Glutamate receptors (mGluRs) models to investigate synaptic organization
Metabotropic glutamate receptors (mGlurs) are important determinants of glutamatergic transmission.
These receptors are evolutionary conserved and we have been able to investigate how these molecules control simple behaviours in the 302 neuronal cell (approx 6000 synapse) simple nervous system of C.elegans.
Plasticity of behaviour for good and bad
We have established facets of worm behaviour that can be readily measured in response to food withdrawal, a mimic of a starvation response.
Plasticity through scaffolding molecules
The classic model used to study long-term changes is long-term potentiation (LTP), in the hippocampus. It is thought that the molecular changes that occur to bring about LTP are important for learning and memory.
Protein misfolding and the neuroprotective role of molecular chaperones
Molecular chaperones such as heat shock proteins (HSPs) regulate protein folding, misfolding, protein degradation and signalling pathways involved in neuronal death and survival.
