Funding Amount
$816,908.00
Summary
Friedreich ataxia (FRDA) causes debilitating motor and cognitive deficits. We propose a longitudinal multi-modal magnetic resonance (MR) imaging study to measure different types of tissue in the brain in this disease. We seek to understand how the brain reorganises itself due to cell loss in the spinal cord, cerebellum and cerebral cortex. This study will establish sensitivity of a range of MR imaging measures as potential biomarkers for use in large multi-centre drug trials in this disease.
Cellular Modelling Of Attention Deficit Hyperactivity Disorder (ADHD) Risk Genes

Summary
Attention deficit hyperactivity disorder is a prevalent behavioural disorder affecting 7.4% of Australian children and adolescents. It has a strong genetic component with high heritability estimates (75–90%) comparable to other serious mental illness such as autism and schizophrenia. Identification and functional characterization of the genetic causes of this disorder will enhance our knowledge of its neurobiology and revolutionise the drug treatment of the disorder.
Quantifying The Role Of Epigenetic Factors In Neurocognitive Outcomes: A Twin Study

Funding Amount
$1,516,790.00
Summary
We aim to identify the environmental factors in early life that contribute towards an individual brain development using MRI brain scans and related psychological skills measured in late childhood. We are using twins to better understand differences in their early life environments independent of genetics.
A Multi-cohort Investigation Of The Effects Of BDNF Val66Met On Tau, Neurodegeneration And Cognition In Preclinical Alzheimer’s Disease

Funding Amount
$325,758.00
Summary
There are currently no disease modifying therapies for Alzheimer’s disease. We will elucidate the role of a genetic polymorphism that has previously been shown to exert neuroprotective effects on memory decline and brain volume loss associated with Alzheimer’s disease. By studying the role of this gene in multiple cohorts of individuals with varying degrees of Alzheimer’s disease risk, this study has high potential to uncover novel disease-modifying strategies for the treatment of the disease.
Characterisation Of Eurl, A Novel Gene Implicated In The Etiology Of Abnormal Brain Development And Intellectual Disability

Funding Amount
$597,541.00
Summary
Intellectual disability affects around one per cent of Australians, and can arise from genetic abnormalities during fetal life, such as through abnormal regulation of gene expression. We have identified a novel gene, known as eurl, which controls brain assembly as well as the ability of neurons to form functional connections within the brain. We will investigate how this novel gene controls brain development, and characterise eurl as a potential therapeutic target for learning and memory.
APLP2: A Neuroprotective Receptor For Acute Brain Injury

Funding Amount
$648,739.00
Summary
Traumatic brain injury (TBI) is the major cause of deaths in Australians under 45 years of age. We have shown that the amyloid precursor protein (APP) is protective in models of TBI. To understand how APP is neuroprotective we have isolated APP binding proteins and identified the amyloid precursor-like protein 2 (APLP2) molecule as a strong candidate for the APP-neuroprotective receptor. This grant will investigate the interaction between APP and APLP2 as a novel neuroprotective pathway in TBI.
Biomaterials For The Direct Reprograming Of Reactive Astrocytes Into Functional Neurons

Funding Amount
$630,500.00
Summary
We will employ peptide inspired hydrogel nanoscaffolds that can be injected into a brain lesion as a single injection to provide chemical and physical support for the surrounding cells. We will utilize various modifications to these materials to reprogram inflammatory cells into neurons, whilst also promoting the survival, maintenance and growth of existing neurons to encourage repair.
Efficacy Of A 3-month Aerobic Exercise Regime For Restoring 'brain Health' In Heavy Cannabis Users

Funding Amount
$1,209,221.00
Summary
Over a ten-year period, we, and others have documented the brain and psychological harms associated with regular cannabis use. We have now shown that these harms are not permanent, but can be restored. However, the recovery process takes a long time. This study will build on our extensive work to date and, for the first time, investigate whether a specific form of exercise will cause accelerated and beneficial changes in i) the brain and ii) the daily lives of heavy cannabis users.
Seizures appear unpredictable and greatly affect the quality of all aspects of life for patients with epilepsy and their carers. New advances in complex systems theory suggest that transitions from normal brain activity to seizures are preceded by measurable changes in the brain’s responses to stimuli, known as critical slowing. Measurement of critical slowing will enable prediction of seizures, providing a warning system, and possibly an opportunity to deliver preventative therapies.
Signaling Pathways To Enhance Potency Of AMPK-targeting Drugs

Funding Amount
$661,966.00
Summary
Sedentary lifestyles and consumption of high energy foods has led to epidemics of obesity-related metabolic diseases that place enormous financial and medical burden on the Australian economy. An attractive drug target to treat these diseases is AMP-activated protein kinase (AMPK) which functions as both a cellular fuel gauge and co-ordinator of whole-body metabolism. Our goal is to improve AMPK drug potency by identifying novel processes that sensitize AMPK to drugs.
