Summary
The malaria parasite’s survival is reliant on efficient cell movement - a process that depends on the remodeling of the parasite actin cytoskeleton. The aim of this project is to understand how the actin cytoskeleton is disassembled when the parasite moves and to dissect the role of a key parasite protein, PfADF1, in the process. This project will elucidate fundamental insights into a key aspect of malaria parasite biology and, significantly, will shed light on how parasite movement can be inhib ....The malaria parasite’s survival is reliant on efficient cell movement - a process that depends on the remodeling of the parasite actin cytoskeleton.

Summary
Parkinson s disease (PD) is a progressively disabling movement disorder afflicting many elderly Australians. It is caused by the degeneration of specific nerve cells in the brain that produce certain chemicals and patients suffer from an inability to move fluently (or ultimately at all). At present we do not know what triggers this neurodegeneration, but it is believed that complex interactions between inherited (genetic) and environmental factors contribute significantly to the phenomenon.

It is caused by the degeneration of specific nerve cells in the brain that produce certain chemicals and patients suffer from an inability to move fluently (or ultimately at all). At present we do not know what triggers this neurodegeneration, but it is believed that complex interactions between inherited (genetic) and environmental factors contribute significantly to the phenomenon. This project aims to learn more about these complex interactions and their association with PD. People with PD and unaffected individuals will be recruited from throughout Australia and we will look for specific combinations of genetic, environmental and lifestyle factors that either increase or decrease an individual's risk for PD. This research will identify the most common dominant genetic and environmental influences for PD in Australia, enabling scientists to focus on the most relevant biological pathways to target therapeutically.Read moreRead less
Reconsideration Of The Mechanisms Underlying Movement Changes With Pain

Summary
Pain changes the way we move. Although undisputed, there is a surprising lack of agreement regarding the underlying mechanisms. This project involves an innovative mix of neurophysiological methods to investigate how the drive to muscle cells from the nervous system is altered during pain. We aim to resolve the perplexing problem of how pain changes our ability to activate muscle. Our findings are likely to provide a clear understanding of the underlying mechanisms and guide rehabilitation.
Proprioception is how we sense the position of our joints, the movements of our joints, and the forces generated by our muscles. Disturbances of proprioception can cause major disruption of all movements and postures. We will undertake novel studies of how signals generated in the brain which command our movements contribute to all key aspects of proprioception. Finally we will unravel how the brain builds up the overall 'scheme' of our body which we need to make any accurate movement.
