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.
Immunological Therapies For Cancer, Chronic Infection And Autoimmunity

Funding Amount
$10,891,788.00
Summary
The team comprises five leading scientists with a history of successful investigation into the role of the immune system in cancers, chronic viral infections, and autoimmune diseases. There is a large unmet need for effective solutions with fewer side effects in these diseases which cause a high disease burden in our society. In this program, we particularly seek to develop novel vaccines for chronic infections and autoimmune diseases, and to improve the safety of bone marrow transplantation.
Role Of Insulin-regulated Aminopeptidase In Ischemic Stroke Damage

Summary
Stroke is a neurovascular disease which is the leading cause of adult disability. A focus of our research group is to investigate the role of a protein called insulin-regulated aminopeptidase (IRAP) in ischemic stroke. We have shown a dramatic protection from ischemic brain damage in mice with deletion of the IRAP gene. The aims of this study are to explore the potential use of the newly developed IRAP inhibitors in protecting brain damage following ischemic stroke and to determine the role of I ....Stroke is a neurovascular disease which is the leading cause of adult disability.

Intergenerational Impacts Of Paternal Immune Activation On Brain Function And Dysfunction

$997,690.00
Summary
We recently discovered that infection of male mice with a parasite (Toxoplasma gondii) before conception can change the epigenetic information in the sperm and alter behaviour of the offspring. This is the first evidence that pathogenic infection in males can affect the next generation. We will investigate how infection with other major pathogens, including bacteria and the virus causing COVID-19, may affect sperm epigenetics and offspring health, including their brain function and dysfunction.
Regulation Of Arthritis And Skin Inflammation By Annexin-1

Summary
Annexin-1, an antiinflammatory substance, mediates many of the actions of steroids. Our studies will reveal whether annexin-1 will reduce inflammatory and immune responses, and secondly, determine the substances regulated by annexin-1 in immune responses. If annexin-1 is found to mediate the immune regulatory effect of steroids, its capacity to be involved in the beneficial effect of steroids may have an important impact in treatment of arthritis and other inflammatory diseases.
Functional Assessment Of CD40 In The Development Of Multiple Sclerosis

Summary
Many of the genes which affect susceptibility to Multiple Sclerosis (MS) have recently been identified. Two of these genes were first discovered in an Australian study published in Nature Genetics in 2009. One of these is CD40, which controls immune cell activation. In this project we aim to establish how the genetic variant identified affects the function of the CD40 gene in MS. CD40 may prove to be a good therapeutic target, with agents available to modulate CD40 available already.
Perioperative Administration Of Dexamethasone And Infection- The PADDI Trial

Funding Amount
$4,832,815.00
Summary
The PADDI Trial is a large (8,800 patients) international, multicentre, randomised, controlled, non-inferiority safety and effectiveness study that will run for five years. It will examine the benefits and complications of administering 8mg of a steroid drug (dexamethasone) to adult patients undergoing non-urgent surgical procedures who receive general anaesthesia. The main outcome is surgical site infection 30 days after surgery. The influence of diabetes will also be investigated.
Human Fc Receptors In Antibody Mediated Inflammation

Summary
A series of major Australian discoveries is leading to the development of therapies to treat major inflammatory diseases such as rheumatoid arthritis, lupus and similar autoimmune diseases where there is a significant unmet need for new therapies. A major molecule, caled Fc receptor was discoverd by the researchers who have now found new ways to prevent it activating inflammatory cells and therby preventi tissue destruction.
Regulation Of Leukocyte Recruitment In Inflammation

Funding Amount
$686,656.00
Summary
In inflammatory diseases such as asthma, arthritis and atherosclerosis, white blood cells enter affected tissues causing inflammation and tissue destruction. This research will investigate the processes whereby white blood cells enter affected tissues, particularly how they exit the circulation, and migrate throughout tissues during inflammatory responses. An improved understanding of this process may identify new ways of interfering with the disease process in various inflammatory diseases.
