Summary
Age-related cognitive decline, a hallmark of dementia, coincides with reduced activity of neural precursor cells and reduced rate of neuron production in the hippocampus – a key brain structure for learning and memory. Importantly, we have demonstrated that exercise can activate neural precursor cells and boost the production of new neurons as well as improve learning and memory. This project will explore the cellular and molecular mechanisms behind these exercise-induced benefits on cognition.
A Novel Intracellular Roadblock To Cobalamin Utilization In Ageing And Alzheimer�s Disease

Funding Amount
$11,304.00
Summary
Vitamin B12 is required for red blood cell formation, DNA synthesis and normal neurological function. B12 deficiency contributes to age-related cognitive decline and Alzheimer�s disease. This research will provide important new information regarding the ageing process and the impact that brain changes associated with ageing and Alzheimer's disease have on B12 metabolism. It will provide important information related to the therapeutic potential of B12.
Defining The Function Of Apolipoprotein-D In Alzheimer's Disease

Summary
Alzheimer's disease (AD) prevalence is rising and there is no curative treatment. Neurotoxic amyloid-beta peptide and concomitant lipid oxidation in the brain contribute to the cause of AD. We have identified a new pathway by which a protein called apoD may inhibit lipid oxidation in the AD brain. We will test the impact that changing apoD levels in neurons and in genetically modified mice has on neuron stress and AD-like characteristics. This may reveal new avenues to prevent or treat AD.

Summary
Novel postsynaptic functions of the microtubule-associated protein tau. The protein tau is present in abnormal deposits in brains of individuals with dementia. The main aim of this project is to unravel and understand in detail new roles of tau in neurons and thus shed new light into normal brain function. Understanding these new functions of tau will aid in identifying new ways to treat these debilitating diseases.
Improving neuronal cell function with cell permeable copper complexes. Metal-based drugs offer an exciting new approach to treatment of neurodegeneration. However, little is known about how cells metabolise these drugs and this information is critical for further drug development. This project will determine how metal-based drugs are metabolised by neuronal cells and how this may result in therapeutic benefit.
Cellular mechanisms that protect against copper-bound beta-amyloid. This project will investigate some of the brain’s own mechanisms for protecting itself against Alzheimer’s disease. Understanding these mechanisms will be important for developing future therapeutic strategies for treating Alzheimer’s disease.
Association Between Sirtuin Single Nucleotide Polymorphisms And Functional Markers Of Brain Health In Ageing

Summary
Sirtuins are histone deacetylases that have been reported to play a pivotal role in energy expenditure, mitochondrial function and pathogenesis of metabolic diseases, including neurodegenerative disorders and Alzheimer’s disease in particular. In this study, we will focus on the genes encoding sirtuin families, and examined the association between single nucleotide polymorphisms within genes encoding sirtuin families and functional markers for brain health.

Summary
The role of the unfolded protein response in tau neurobiology and pathology. The main role of the protein tau is the stabilisation of the scaffolding of cells. In a group of dementias, tau forms abnormal clumps within the cells of the brain causing them to die. This project will investigate the cellular processes involved in normally preventing tau proteins from clumping and their role in the development of the abnormal tau clumps.
The Role Of PARK9 And Autophagy In Parkinson's Disease.

Summary
With an ageing population, the health burdens of neurodegenerative diseases such as Parkinson's disease (PD) are numerous. We have found a role for a PD suspectibility gene, PARK9, in autophagy- a neuroprotective degradative pathway, that may also be involved in keeping ÎSyn, a pivitol protein in PD, levels in check.
Understanding the contribution of neuroinflammation in acute and chronic neural injury. A major focus of this project will be investigating the involvement of neuroinflammation in neural cell damage. It will explore how neuroinflammation contributes to this damage in both acute and chronic neuropathologies.
