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.

Investigating Underlying Mechanisms Linking Type 2 Diabetes With Alzheimer’s Disease Pathology

Funding Amount
$701,950.00
Summary
With type-2 diabetes representing a major risk factor for neurodegenerative diseases such as Alzheimer's disease, it is important to understand the underlying mechanisms. This project will provide significant insight into how T2D impacts the brain with a focus on how deficiencies in brain inuslin signaling drives neurodegeneration. We will also evaluate novel inuslin like molecules at improving brain insulin siganling and preventing or slowing down the neurodegenerative process.
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.
The Genetic And Environmental Determinants Of Amyloid Deposition In Older Individuals: An Amyloid Imaging Study Using The Twin Design

Funding Amount
$643,267.00
Summary
Alzheimer’s disease is characterised by the deposition of amyloid plaques in the brain. We don’t fully understand how amyloid deposition occurs and what contribution is made by genetic and environmental factors. Amyloid deposition in the brain can now be quantified during life using positron emission tomography. In this study, we will examine brain amyloid in twins, which will determine what proportion of the pathology is attributable to environmental factors that may be modifiable.
Exploring Scanning Ultrasound (SUS), A Novel Method To Treat And Prevent Neurodegenerative Disease

Funding Amount
$765,708.00
Summary
We developed a novel scanning ultrasound (SUS) protocol that clears toxic protein aggregates and restores memory function in mouse models of Alzheimer's disease (AD), without the need for therapeutic agents. Here we aim to determine whether SUS has preventative potential, whether there are synergistic effects, and whether a therapeutic antibody combined with SUS leads to an enhanced therapeutic outcome. Together this will guide the development of an ultrasound therapy in AD patients.
