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.

Summary
Innate lymphoid cells (ILCs) are specialized cells that defend the body against invading microorganisms at the body’s surfaces, mediate pathogen clearance and tissue repair but may also drive inflammatory conditions such as allergic asthma and inflammatory bowel disease. We will investigate the molecular switches that regulate this novel cell type and potentially uncover novel molecules or pathways for therapeutic targets.

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.

Summary
Natural killer cells are innate cells that provide first line defense against infection and cancer. The recent discovery of a novel innate cell population has modified our vision of the early events necessary for immune protection. Understanding the role of these cells is critical as they could represent viable therapeutic targets. We have developed unique mouse models to experimentally target this population to determine how they are generated and their role in combating infection and cancer.

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.
