Summary
Organ transplantation is a life-saving treatment for end-stage organ failure. However, patients must take immunosuppressive drugs to prevent rejection, a lifetime of which increases the risk of infection and cancer. An alternative to drugs is to manipulate the immune system from within. We discovered a way to boost the immune ‘regulators’ so that they stifle the graft-destroying response. We are optimising this approach with the aim of transplanting organs without long-term immunosuppression.
The Role Of NF-?B Transcription Factor RelA In Regulatory T Cell Homeostasis And Function

Summary
Treg cells constitute an immune regulatory cell population that is essential for the prevention of fatal autoimmunity; however, they also limit immunity against cancer. We have discovered that the factor RelA is of critical importance for Treg development and function. We now aim to illuminate the functions of RelA in detail. Understanding the molecules that impact on Treg cell biology is critical to harness their potential for clinical intervention such as treatment of autoimmunity and cancer.
Targeting Caspase 8 In T-Cell Homeostasis And Disease

Summary
Chronic infectious diseases such as HIV, hepatitis B and tuberculosis impose a massive global health burden and new treatments are desperately needed. This proposal investigates a new approach to improve immune responses and clear chronic infections. Our multidisciplinary team will define the molecular and cellular biology underlying this approach and translate our findings by re-purposing a drug already approved for other indications in humans.
Australia has one of the highest asthma rates in the world. In this project we will study how natural regulatory T cells suppress asthma in a mouse model. We will determine where and when interactions between regulatory T cells and allergic T cells occur, and define the mechanisms used by regulatory cells to mediate their suppressive effects. Our findings will aid in understanding why asthma develops and how it may be controlled by the immune system itself.

Summary
Chronic Kidney Disease is one of the major causes of death in Australia. Therapeutic success with regulatory T cells (Tregs) capable of targeting autoimmune kidney disease would have major clinical implications. In the proposed study, we will use Chimeric Antigen Receptors (CARs) T cells by redirecting them to diseased organs, protect against kidney injury. These CAR T cells will recognise renal antigens and target immune cells and antibodies to limit kidney damage.
The Impact Of Obesity On Immunological Tolerance Of The Fetus

Summary
Obesity increases the risk of miscarriage during pregnancy. The reasons for this are not known, although it is thought that abnormal levels of hormones and metabolic parameters are a contributing factor. We hypothesise that the immune system plays a role. In this project we will determine if obesity upsets the fine-tuning of the immune system that is crucial for successful pregnancy. Understanding the reason behind adverse pregnancy outcome will allow appropriate management of maternal obesity.
