Summary
Giant cell arteritis (GCA) is the most common form of vasculitis in people over 50 years of age. If untreated it can cause catastrophic complications including blindness, though this can be prevented if treated early. Although there is clear evidence for a role of genetic factors in GCA, these have been little studied. We have established an Australian-led International consortium, with clinical, basic science and statistical expertise to thoroughly investigate this devastating disease.
Galectin-3 And Phagocyte Function In Severe Asthma

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.
Cell Surface Mucins In Gastrointestinal Infection, Inflammation And Cancer Development

Summary
Cell surface mucins are protective molecules that line all the wet surface of the body, including the gastrointestinal tract. Our research has uncovered that mucins regulate cell growth and cell death. Inappropriate control by the mucins, could lead to chronic inflammation and formation of cancers. We will test how important these molecules are in the development of cancers in the intestine, and further explore the mechanism of action.
Testing Novel Therapies Using Paediatric Brain Tumour Models

Summary
Brain tumours are the second most common childhood cancer, with 300 children affected in Australia each year. Many children with brain tumours continue to die of their disease, whilst survivors are often left with devastating life long side effects. Our goals are to harness the power of innovative model systems of childhood brain tumours, in order to test the effectiveness of new treatments for these devastating diseases, so that the most promising therapies can be taken through to the clinic.
ASPREE-D; Aspirin In The Prevention Of Depression In The Elderly

Funding Amount
$796,784.00
Summary
The ASPREE (ASPirin in Reducing Events in the Elderly) study is a 5 year RCT of aspirin (100mg daily) or placebo in 19,000 healthy people over 70. We aim to augment the existing infrastructure of ASPREE in order to confirm the utility of aspirin for the prevention of depression in the elderly (ASPREE-D). The primary aim of ASPREE-D is to determine if use of low-dose aspirin reduces the incidence of de-novo episodes of depression in healthy individuals over 70 years of age.
Imaging Neutrophil And Endothelial Function In Acute Glomerulonephritis

Summary
The glomerulus is a group of small blood vessels which form the filtering component of the kidney. In many diseases, it can be the target of an inappropriate inflammatory response during which white blood cells accumulate in the glomerular blood vessels and cause damage. In this project, we will visualise the blood vessel lining of the glomerulus in order to understand how white blood cells damage this region and cause leakage of protein leak into the urine.
Reprogramming Macrophage Function In The Elderly To Rescue Impaired Inflammatory Responses To Muscle Injury

Funding Amount
$410,983.00
Summary
Muscle injury in the elderly often takes longer to heal than in younger people, however the cells responsible for this delayed healing are not well understood. Key inflammatory cells required for muscle repair in young hosts are macrophages. However, during aging we have shown that macrophage function is altered, but the mechanism is unknown. This project aims to determine the mechanisms behind age-related changes to macrophages and whether they can be targeted to improve elderly muscle repair.
Preclinical Evaluation Of A Novel Allosteric IL-1R Inhibitor (rytvela) For The Prevention Of Perinatal Inflammation-induced Fetal Injury

Funding Amount
$1,377,827.00
Summary
Interleukin-1 (IL-1) is a potent inflammatory protein involved in many inflammatory disorders, including preterm birth (PTB). Blocking the actions of IL-1 in pregnancies at risk of delivering preterm may protect the fetus from PTB and the long-term harm of exposure to inflammation before birth. Using four different models of antenatal inflammation, we will explore the use of a new IL-1 inhibitor to see if it blocks inflammation ‘in utero’ and improve neonatal health and development.
Monocytes On Patrol – Key Mediators Of Renal Injury In Glomerulonephritis

Funding Amount
$772,888.00
Summary
The glomerulus is the filtering component of the kidney. In many diseases, it can be the target of an inappropriate inflammatory response. As part of this response, white blood cells accumulate in the glomerulus where they cause damage. In this project, we make use of special microscopes to examine the glomerulus during an inflammatory response, with the aim of understanding the actions of white blood cells present in glomeruli and how they cause inflammation and damage the glomerulus.
Attenuating Severe Infections In Chronic Inflammatory Diseases Through Modulation Of Transforming Growth Factor-β Activity

Summary
Asthma and chronic obstructive pulmonary disease (COPD) are characterised by enhanced TGF? expression, which is accompanied by susceptibility to recurrent viral and bacterial infections. Such infections exacerbate lung inflammation in these patients, generally requiring emergency department treatment. This project proposes to clarify the therapeutic potential of TGF? inhibitors to reduce the impact of viral infections in patients with COPD and asthma.
