Problems in learning, memory and other complex mental processes are common to many brain disorders. This project will study the impact of mutations on a family of genes reported in autism and schizophrenia, on complex cognitive behaviours using novel behavioural technologies. This will not only shed fundamental insights into the specific mental processes regulated by these genes and their role in disease, but importantly provide novel targets for the development of therapies.
Slowing Progression Of Alzheimer’s Disease By Modulating The Kynurenine Pathway

Summary
Chronic inflammation in the brain in known to be a factor in the progression of Alzheimer's disease. We are exploring if blocking a particular enzyme in a biochemical pathway involved in inflammation, can improve symptoms, or slow progression, of the disease in animal models of AD. If results are as expected, our proposal has the potential to generate a new a therapy for AD.
The majority of stroke results from focal brain infarction, followed by substantial secondary excitotoxic damage in the surrounding areas. Tau has been shown to contribute to excitotoxicity and neurodegeneration in mouse models of Alzheimer’s disease (AD). Preliminary data show that tau reduction also protects against excitotoxic damage after experimental stroke. We aim to dissect the molecular mechanisms of stroke using a tau-deficient mouse model.
Immediate Cooling And Emergency Decompression (ICED) For The Treatment Of Spinal Cord Injury: Pilot, Safety And Feasibility Studies

Funding Amount
$600,008.00
Summary
Victims of Spinal Cord Injury are young, have severe paralysis, complex needs and high lifetime costs. Although urgent surgery greatly improves outcome, it is difficult to achieve because of logistical difficulties. To expand the time window for early surgery, it is proposed to immediately cool patients. This project will conduct the pilot studies necessary before commencing a clinical trial of immediate cooling and emergency decompression (ICED) in patients with cervical spinal cord injuries.
Assessing The Efficacy Of Safe And Simple Neuroprotective Treatments For Chronic Degenerative Conditions Of The Central Nervous System

Funding Amount
$311,860.00
Summary
Current treatments for age-related diseases of the central nervous system (CNS) are limited. We have shown in animal models of acute CNS degenerations that treatment with saffron or low energy infrared light is strongly protective. This project will determine if these treatments prevent CNS damage and dysfunction in animal models of chronic degenerations and add to knowledge of how these treatments work. This research should lay the foundation for testing these novel treatments in humans.
Targeting Autism With Macrocephaly Using Mechanism Based Therapeutics

Funding Amount
$831,652.00
Summary
Autism affects a large number of children in our community and currently there is a lack of any medication to treat its core pathology. In this grant we will study the underlying biochemical changes in the brain that result in autism through the development of a new mouse model of the disorder. This mouse model will then be used test drugs to identify therapeutic targets for the treatment of autism.
NOVEL MECHANISMS UNDERLYING THE SPREADING OF TAU PATHOLOGY IN ALZHEIMER’S DISEASE AND OTHER TAUOPATHIES

Funding Amount
$640,106.00
Summary
Alzheimer’s disease and related dementias affect 230,000 people in Australia, with numbers expected to grow to three times that by 2050. The direct costs for health and residential care alone already exceed $6.6 billion per annum. The underlying pathomechanisms and the processes that drive the progression of neurodegeneration in these devastating disorders remain largely unknown. Here, we will identify novel therapeutic targets and assist in developing therapies for yet incurable diseases.
Long-term Outcomes After Paediatric Traumatic Brain Injury

Funding Amount
$431,000.00
Summary
Traumatic brain injuries during early childhood often result in long-lasting issues including social behaviour problems and post-traumatic epilepsy. Using a unique model of brain injury in young mice, my research aims to identify the biology underlying the changes that cause these issues, and evaluate novel approaches to improve long-term outcomes after brain injury.
The Missing Link: MGluR5 As A Therapeutic Target For Cognitive Decline In Dementia
Funder
National Health and Medical Research Council
Funding Amount
$563,622.00
Summary
Cognitive decline is a core feature of Alzheimer’s Disease (AD), yet there is no cure or treatment. Recent evidence suggests that a protein called mGluR5 could cause brain cells to lose function, leading to memory loss. This project will investigate whether disrupting mGluR5 function can improve cognition in mice with genetic AD. Memory will be assessed in mice using innovative touchscreen tests that closely mimic the tests used in humans.
