Summary
Traumatic brain injury (TBI) is a leading cause of death and disability worldwide and to date there is no therapy to ameliorate this injury. There is increased production of the amyloid precursor protein (APP) following TBI and recent studies have found that APP possesses neuroprotective traits. It is the aim of the current studies to delineate the specific active neuroprotective region of APP and develop them as novel therapeutic interventions for use in TBI.

Summary
The Presenilin and APP proteins are centrally important in inherited, early onset Alzheimer's disease. We have discovered that a shortened form of Presenilin protein, "PS2V", appears to increase specifically the rate at which the APP protein is cleaved to produce the "Amyloid beta" protein fragment that is found in Alzheimer's disease brains. This occurs when brain cells are under oxidative stress. Understanding this process will facilitate development of appropriate therapeutic strategies for t ....The Presenilin and APP proteins are centrally important in inherited, early onset Alzheimer's disease.

Understanding The Contribution Of Iron In Traumatic Brain Injury

Summary
Our group has discovered a novel role of amyloid precursor protein (APP) in cellular iron balance similar to another protein called ceruloplasmin (CP). Both, prevalently found in the brain, convert a damaging iron variety into the safer form. Disruption in either protein leads to cell death. We aim to establish how failure in APP and CP response may be detrimental to traumatic brain injury recovery. Understanding the iron role of APP and CP will lead to therapeutics to counter traumatic injury.

Summary
Alzheimer’s disease and beta amyloid toxicity: Alzheimer’s disease (AD) is the most common form of dementia and is characterized by progressive memory loss, confusion, and cognitive deficits. In 2011, an estimated 269,000 Australians are currently living with dementia and without a significant medical breakthrough soon, it is anticipated that this will rise to about 981,000 by 2050
I am a neuroscientist investigating the functional roles of neurotrophic factors in nervous diseases such as Alzheimer’s disease and spinal cord injury. I am also interested in the mechanisms of how these factors are involved in neural development.
