Summary
Liver disease, a significant burden on society, affects many in the prime of their life. Scarring of the liver is a response to injury due to many factors including alcohol, viruses, obesity, and fatty-liver disease. We have identified a protein associated with liver injury. In this project we will perform a systematic analysis to understand the role of this protein in injury progression. Ultimately we intend to develop tools to prevent and treat liver injury.
A New Paradigm For Class I Cytokine Receptor Activation

Funding Amount
$954,946.00
Summary
Class I cytokine receptors include around 30 receptors with diverse functions such as controlling metabolism and inflammation. Cytokine receptors are molecular switches on cells that receive signals from other cells and transmit this signal into the cell’s nucleus to control the regulation of genes. This project will determine the molecular mechanisms involved in class I cytokine receptors and use this knowledge to develop novel ways to modulate these receptors for clinical applications.
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.
Using Conversational Computer Technology To Improve Diabetes Management: A Randomised Controlled Trial

Summary
The diabetes epidemic is a growing challenge for the Australian health care system with over 1 million Australians living with diabetes. The impact on individuals' lives and the whole of Australian society is very substantial indeed. There is very good evidence that this impact would be reduced by developing new approaches to manage the disease and facilitate improved self-management. Recent developments in information and communications technologies offer some promising new ways and tools for a ....The diabetes epidemic is a growing challenge for the Australian health care system with over 1 million Australians living with diabetes. The impact on individuals' lives and the whole of Australian society is very substantial indeed. There is very good evidence that this impact would be reduced by developing new approaches to manage the disease and facilitate improved self-management. Recent developments in information and communications technologies offer some promising new ways and tools for achieving this. This research will evaluate a computer-controlled, interactive telephone system for improving the management and self-management of Type 2 diabetes in addition to routine care. Patients with Type 2 diabetes will be recruited from Brisbane and each patient will be randomly assigned to receive either this new program or just their usual care from their doctor or Diabetes Clinic. The first group will call the system weekly for six months using a regular phone or a mobile phone if they wish. During the call, they will answer questions by speaking into the phone, listen to feedback and strategies for improving management of their diabetes and then discuss their next targets and behavioural actions. They will receive systematic and tailored advice on blood glucose testing, nutrition and physical activity, as well as medication taking and foot care. The system individualises conversations according to the user s answers and responses over all the interactive sessions. The trial will formally evaluate the clinical impact on blood glucose control and the adoption and maintenance of the targeted health habits, as well as the intervention s cost-effectiveness and users satisfaction with the system. This project s significance lies in the excellent potential of using this new technology to provide a 'low cost' but effective program to help people better manage Type 2 diabetes.Read moreRead less
Macrophage Polarisation And Control Of Pulmonary Inflammation.

Funding Amount
$895,494.00
Summary
As key immune cells, macrophages are polarised to phenotypes that turn inflammation on or off. In cystic fibrosis, defective macrophage polarisation enhances inflammation and prevents lung repair. We are defining the molecules and cellular pathways that control this process and identifying targets for existing drugs that can be used to reprogram macrophages and restore lung repair to improve patient outcomes.
Which Mental Activities And When For Dementia Prevention? The Four Nations Longitudinal Collaboration

Funding Amount
$183,218.00
Summary
We will examine the link between lifetime participation in complex mental activities and long term dementia risk in a level of detail not previously possible. Four major studies of brain health from around the world will join forces for the first time to determine which mental activities are most closely linked to protection from dementia, and when during the lifespan these are most important. Mental activity will be assessed using our recently published Lifetime of Experiences Questionnaire.
TELEPHONE COUNSELLING FOR MAINTENANCE OF PHYSICAL ACTIVITY, WEIGHT LOSS And GLYCAEMIC CONTROL IN TYPE 2 DIABETES
Funder

Funding Amount
$1,285,894.00
Summary
Regular exercise, a healthy diet and weight loss are key to managing type 2 diabetes, yet these are major challenges for most people with diabetes. This study will evaluate the impact of a telephone counselling program to assist people with type 2 diabetes to exercise, eat a healthy diet and lose weight, with the goal of helping them to sustain these changes over the long-term. It is expected that these lifestyle changes will also result in improved blood glucose control and quality of life.
Insulin resistance (the inability of ordinarily insulin-sensitive tissues such as muscle and adipose tissue to respond to insulin) contributes to a number of diseases including diabetes and obesity. A key metabolic step in these tissues is the uptake of glucose from the blood stream. This step is accelerated by insulin thus allowing efficient clearance of glucose from the bloodstream after a meal. Our laboratory has played a major role in showing that insulin regulates glucose uptake into muscle ....Insulin resistance (the inability of ordinarily insulin-sensitive tissues such as muscle and adipose tissue to respond to insulin) contributes to a number of diseases including diabetes and obesity. A key metabolic step in these tissues is the uptake of glucose from the blood stream. This step is accelerated by insulin thus allowing efficient clearance of glucose from the bloodstream after a meal. Our laboratory has played a major role in showing that insulin regulates glucose uptake into muscle and adipose tissue by stimulating the movement of a glucose transport protein from inside the cell to the cell surface (see http:--www.imb.uq.edu.au-groups-james-glut4 for an animated description of this process). The purpose of this proposal is to dissect the molecular mechanisms by which this glucose transporter can be held inside the cell in the absence of insulin and then allowed to be released from this site moving to the surface in the presence of insulin. Our studies over the past 5 years have brought us much closer to understanding this process in detail. The identification of the molecules responsible for this regulatory step will not only aid our understanding of this process but it will also provide a valuable target for development of therapeutic agents that can be used to combat insulin resistance.Read moreRead less
Tolerising Antigen-specific Immunotherapy For Type 1 Diabetes

Funding Amount
$1,395,549.00
Summary
We have developed a new immunotherapy to treat the underlying causes of type 1 diabetes (T1D) while leaving the rest of the immune system intact. To use this in patients, we need better tests to know when immune therapy is working. We will develop new methods to design the therapy and tools to track the relevant immune cells in T1D that work in variable patient groups. The knowledge gained will speed the pace of development and increase the chance of success of immunotherapy in T1D.
