We have identified a microRNA (miRNA) which can elicit the functional outcome of the anti-inflammatory cytokine IL-10. miRNAs constitute a novel mechanism used by cells to regulate gene expression and have shown much promise as a therapeutic tool. Our finding suggests that modulation of miRNAs through the use of miRNA mimics or antisense technology may serve as an alternative and/or synergistic approach for the use of IL-10 as therapy in chronic inflammation.
During injury or infection, our body’s immune system protects us by launching inflammation. But uncontrolled inflammation drives common diseases such as cancer, diabetes and Alzheimer’s. This project will reveal how the body produces interleukin-1? – a protein at the heart of inflammation and disease – so we can design better strategies for treating patients with inflammation-driven disease.
During injury or infection, our body’s immune system protects us by launching inflammation. But uncontrolled inflammation drives common diseases such as cancer, diabetes, Alzheimer’s and Parkinson's. This research program will reveal how the body deactivates inflammasomes – protein complexes at the heart of inflammation and disease – so we can design better drugs for treating patients with inflammation-driven disease.
Manipulating The Fine-turning Of The Innate Immune Response In Disease

Summary
I am an international expert on the body’s first-line defense system, the innate immune response. My Fellowship focuses on studying and manipulating innate immune molecules called interferons. My research will lead to improved management of female reproductive disease, autoimmune disorders, infections and cancer through new diagnostics and therapies targeting the interferon system. The basic knowledge I generate on regulating the immune response will be applicable to a range of medical fields.

Summary
Microbes quickly evolve to evade detection by the innate immune system, the body’s first line of defence against infection. This project investigates the mechanisms by which the immune system recognises bacterial infection, and pathways used by bacteria to avoid these defences. This research will lead to a better understanding of mechanisms underlying resistance and susceptibility to bacterial infection.
Toll Like Receptor signalling as a mediator of sex differences in pain, opioid and alcohol action. Brain immunology will be examined in this project to see if the signalling of a receptor called Toll Like Receptor 4 can explain sex differences in pain, and the action of pain killers and alcohol. These findings will have significant implications on the understanding of male and female brains, and will assist in the design of new drugs to treat brain and spinal cord diseases.

Novel immune cell subsets in the centre nervous system and supporting tissues. This project aims to identify and characterise novel resident immune cell subsets within the brain and retina, and their close supporting tissues.

This project aims to identify and characterise novel resident immune cell subsets within the brain and retina, and their close supporting tissues. The project expects to generate new knowledge in the areas of neuroimmunology and ocular immunology by using molecular and cellular techniques to examine the diversity of immune cells within the brain and retina. It is expected that the project will advance our understanding of the biological mechanisms that protect the central nervous system from harmful inflammation and thus improve our knowledge of the immunobiology of the brain and eye.Read moreRead less
The Interferon System In Innate Immune Responses To Disease

Summary
My research investigates special proteins called cytokines in the body’s first-line defence against infection, inflammation and cancer. I will characterise how cells respond, the signals that mediate effects, using sophisticated genetic and new computational techniques to manage and analyse data. One focus is a new cytokine we discovered that protects against infections of the reproductive tract –a global health and socio-economic problem affecting 1 billion people.
The role of P2X7 and P2X4 receptor mediated innate phagocytosis in pathogenesis and treatment of neurodegenerative diseases. This project will identify how inherited variation in two proteins of the brain can accelerate the removal of neurones and predispose to a range of neurodegenerative diseases. Knowledge of the biological basis of this finding will allow a search for new compounds which will slow and protect against this form of neurodegeneration.
Investigating the role of the innate immune complement system in the abnormal development of the central nervous system. Past research has discovered a surprising link between the immune system, dietary folate deficiency and the development of the embryonic brain. This project will investigate the immune system in the developing brain, in order to understand the causes of developmental defects such as neural tube defects, and the role dietary folate plays in this process.
