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.
Stroke outcomes directly relate to brain tissue rescue. We have contributed to changes in clinical practice through many clinical trials of new protocols and therapeutic strategies. Our program will focus on brain salvage in the pre-hospital setting and the acute hospital environment. We will use novel approaches to enhance brain recovery and design new implementation strategies to maximise the benefits of these therapeutic advances.
Restoration Of Cognitive Deficits Induced By Diabetes Through The Modulation Of Cerebrovascular Integrity

Summary
Diabetes is a known risk factor for the development of dementia. However the details of this association have not been known. Recent evidence consistently shows that the integrity of blood vessels in the brain may be central to the onset of dementia, and consistently, damaged brain blood vessels are often reported in diabetic patients and animal models. This project is the first to target in restoring the integrity of those brain blood vessels in order to reverse diabetes-associated dementia.

Summary
Diabetes is known to increase the risk of dementia. Although the mechanisms are currently unknown, a recently emerging body of evidence suggest that damaged blood vessels of the brain may be central to onset and progress of cognitive dysfunction. Consistently, the dysfunction of brain blood vessels is often observed in the brain of diabetes subjects. Therefore, this project will investigate whether the amelioration of disrupted brain blood vessels restores the cognitive function in diabetes.

Summary
Mature red and white blood cells develop from hemopoietic stem cells in the adult bone marrow. The production of red blood cells is primarily controlled by the hormone erythropoietin (epo). The availability of this hormone in a recombinant form has aided in the treatment of numerous forms of anaemia resulting from kidney failure, malignancies, and AIDS.

The production of red blood cells is primarily controlled by the hormone erythropoietin (epo). The availability of this hormone in a recombinant form has aided in the treatment of numerous forms of anaemia resulting from kidney failure, malignancies, and AIDS. Previously we had identified that the protein Lyn must be present inside primitive red blood cells for epo to stimulate them to become mature functional cells. We have identified six molecules which interact with Lyn in red blood cells. We have shown that amolecule called HS1 is important for epo function in individual red blood cells and now we plan to investigate its functions in whole animals, including mice that lack the HS1 gene. We have also shown that a molecule called Trip1 is important for red blood cell development. Interestingly, this molecule also interacts with the thyroid hormone receptor and can influence the effects of epo and thyroid hormone on red blood cell development. The interplay between these two hormones will be looked at in more detail both at the cell and whole animal levels in normal mice and those lacking the thyroid hormone receptor gene. The third Lyn binding molecule we isolated is a novel gene-we have named it ankyrin repeat protein in line with the molecules it is related to. This gene is expressed in red blood cells and we aim to investigate what role it plays in the development of these cells. The fourth gene is also novel and is closely related to another called AFAP-110, which can exert effects on the structure of a cell. Its role in red blood cell structure will also be investigated. Finally, the last two molecule we have identified are both novel and are unrelated to any other known proteins. As above, the effects of these two molecules on red blood cell development will be investigated.Read moreRead less
Missing Voices: Communication Difficulties After Stroke And Traumatic Brain Injury In Indigenous Australians

Funding Amount
$655,310.00
Summary
Acquired communication disorder (ACD) is a common result of stroke and traumatic brain injury (TBI) and has a devastating impact on victims’ everyday lives. Stroke and TBI occur more than twice as frequently in Indigenous as in non-Indigenous populations, but current uptake of communication rehabilitation services is low and long term outcomes for the individuals are unknown. This Australian first study will examine the extent and impact of ACD in urban and rural Indigenous Australians.
Dementia Associated To Diabetes: Prevention Through The Modulation Of Cerebrovascular Integrity

Summary
Diabetic insulin resistance is reported to induce cognitive decline and dementia. An accumulating body of evidence suggest that compromised integrity of neurovascular unit and following changes in cerebral lipid homeostasis may be centrally involved in the neurodegeneration and cognitive deficits. Therefore, the project aims to prevent the insulin resistance-associated cognitive impairment by modulating the integrity of cerebrovasculature and lipid homeostasis.
REACH: Randomised Trial Of EArly Rehabilitation In Congenital Hemiplegia

Summary
Infants with asymmetric brain lesions are at high risk of congenital hemiplegia. This study compares modified CIMT to an equal dose of bimanual training in 150 infants recruited at 3-6 months. Both therapies will be parent-delivered supported by experienced clinicians. Outcomes include use of the impaired hand in bimanual tasks, cognitive and motor development at 12 and 24 months c.a. with measures of neural structure and functional connectivity at 24 months.

Developing New Therapeutic Strategies For Brain Cancer

Summary
Each year, over 1,500 Australians will develop brain cancer. Unlike many cancers, it cannot be prevented by lifestyle changes. Adults with brain cancer usually die within 2 years. The overall aims of this funding are to extend patients' lives and build brain cancer research in Australia so that we have the best chance of curing this disease. The expected outcome is clinical trial of drug candidates for the most common and most deadly brain cancer, high-grade glioma.

Summary
We have developed a new high-resolution optical imaging technology. The unique aspect of our research has been to redesign the imaging probe, miniaturising it to a few hundred microns in diameter, and encase it in a hypodermic needle – a ‘microscope-in-a-needle’. We are developing specific imaging probes to aid in the assessment of lung disease; the diagnosis of liver disease; and integrated into a brain biopsy needle to enable safer brain biopsies.
