Summary
Asthma, a major chronic inflammatory disease affects more than 2 million Australians. Neutrophilic severe asthma is not responsive to current therapies. We have recently made a significant advance in understanding neutrophilic asthma, reporting low levels of a protein called galectin-3 (gal-3). In this project we will explore the role of gal-3 its effect on the resolution of inflammation. This study will result significantly advance the knowledge of the mechanisms of neutrophilic severe asthma.

Summary
Hepatitis C virus (HCV) is a serious viral pathogen that causes significant liver disease. This proposal plans to examine how two proteins from the HCV, core and NS5A, interact with host proteins and pathways to facilitate viral replication and release of HCV; two processes that are poorly understood. Specifically we will tag viral proteins to allow us to investigate the HCV life cycle in living cells and determine the role of core and NS5A in facilitating HCV replication.

Summary
Presently, liver disease from chronic hepatitis C and obesity represents a major health problem. Overall, approximately 50% of Australians with chronic hepatitis C are obese and these patients are at significantly increased risk of rapidly progressing to liver failure. It is now recognized that fat derived factors play an important role in regulating inflammatory responses. This grant proposal aims to gain insight into how liver and fat derived inflammatory factors interact to promote increased ....Presently, liver disease from chronic hepatitis C and obesity represents a major health problem.

Summary
In Australia, hepatitis C (HCV)-related morbidity and mortality are rising. One of the most important recent breakthroughs in clinical medicine is the approval of safe, simple, interferon-free HCV therapies with cure rates >95%. Although people who inject drugs account for the majority of new and existing cases of HCV, reinfection following treatment can occur. The goal of this Project Grant is to examine HCV treatment and reinfection following successful therapy among people who inject drugs ....In Australia, hepatitis C (HCV)-related morbidity and mortality are rising.

SCALE-C: Strategies For Hepatitis C Testing And Treatment In Aboriginal Communities That Lead To Elimination

Funding Amount
$2,175,170.00
Summary
Prevalence of hepatitis C infection within the Aboriginal population is among the highest of any identifiable population in Australia. Highly effective, direct-acting antiviral (DAA) therapy, and their listing on the PBS in 2016 has revolutionised HCV clinical management in Australia. The SCALE-C study will evaluate an established test and treat model to rapidly scale-up DAA within four Aboriginal communities to determine both impact on community prevalence and ongoing transmission.
Individualising Care For Patients With Chronic Hepatitis C: Predicting Side Effects And Treatment Response Using Genomic And Proteomic Approaches.

Funding Amount
$55,575.00
Summary
Patients undergoing treatment for hepatitis C must endure a treatment characterized by unpredictable treatment side effects and uncertainty about the likelihood of cure. This project will investigate genetic predictors of treatment related side-effects and protein markers to predict treatment response. Better definition of the risks and benefits of therapy, may facilitate patients and clinicians to make more informed decisions about treatment, thus individualising treatment and potentially impro ....Patients undergoing treatment for hepatitis C must endure a treatment characterized by unpredictable treatment side effects and uncertainty about the likelihood of cure.

Effect Of Sex Steroids, Inflammation, Environmental And Biopsychosocial Factors On Cardiometabolic Disease Risk In Men

Funding Amount
$1,817,271.00
Summary
Heart disease is more frequent and occurs at an earlier age in men than women. The reason is unknown. Apart from obesity and associated disturbances of metabolism, changes in sex hormones such as testosterone, together with the effects of inflammation may be important, and may in turn be affected by environment, lifestyle behaviours, and stress. To untangle these relationships, we will use cutting edge technology, in a large sample of men, in partnership with other international scientists.
De Novo Mutations And The Pathogenesis Of Childhood-onset Autoimmune Disease
Funder
National Health and Medical Research Council
Funding Amount
$1,406,510.00
Summary
This project aims to reveal the gene abnormalities that cause devastating autoimmune diseases to develop in some children, such as Type 1 diabetes, juvenile arthritis and autoimmune destruction of blood cells. The project will use new technologies to identify alterations in the DNA sequence of a child compared to either of their parents, and to test suspicious DNA alterations in laboratory mice in order to understand the gene effects and evaluate new treatments.
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
