The innate immune response is our primary defence against infection, but must be controlled carefully to avoid chronic inflammation and autoimmunity. Studying tiny regulators of gene function called micro-RNAs and unique cellular pathways, we aim to understand the “big picture” of genetic regulatory systems in innate immunity to provide new insights into inflammation and infection, the genetic basis of diseases, and to identify new potential therapeutic targets, biomarkers and antiviral targets.
A Systems-biology Approach To Understanding The Beneficial Heterologous Effects Of Neonatal BCG Vaccination In A Melbourne-based Randomised Controlled Trial

Summary
BCG vaccine (usually used to protect against TB) also enhances the immune system of young babies to protect them against infections other than TB. We have a large collection of blood samples from a study in which babies were randomised to be given BCG vaccine at birth or no BCG. We will use these to understand the immunological and molecular mechanisms by which BCG boosts the immune system to protect against infections other than TB.

Summary
Many inflammatory driven diseases such as arthritis, atherosclerosis and septic shock are also associated with cell death. This project will identify, at the molecular level, how cell death signalling specifically acts to trigger pathological inflammation. As such, it will identify novel targets for the development of next generation anti-inflammatory drugs.
The Dual-edged Sword Of Zinc As An Innate Immune Antimicrobial Weapon Against Uropathogenic E. Coli

Summary
Infectious diseases are a major global health threat, and urinary tract infections (UTI) are one of the most common infectious diseases. Most UTI are caused by uropathogenic E. coli (UPEC). In order to cause infections, UPEC must be able to overcome our body’s first line of defence, the innate immune system. This project seeks to understand how our innate immune system uses zinc to combat bacterial infections, and how UPEC is able to defend against such responses in order to cause disease.
The Regulatory Role Of Clec12A In Antigen Presentation And Inflammatory Disease

Summary
The immune system maintains a balance between initiating immune responses to infections and suppressing immune responses in health. We have identified, on the surface of specialised immune cells, a protein that is critical for regulating immune responses and dampening down inflammation. This proposal aims to determine how this protein functions in health and under inflammatory conditions, and to develop approaches based on its molecular interactions to reduce inflammatory disease.
