Summary
Salmonella are important pathogens of humans causing diseases ranging from gastroenteritis, typhoid fever to arthritis. Like most if not all infections, the early interaction between the host and the bacterium is characterised by very non-specific symptoms. These non-specific symptoms arise because the so-called innate immune system is activated by the infection. The purpose of this grant is to establish whether these non-specific symptoms, caused by the release of immunological homrones called ....Salmonella are important pathogens of humans causing diseases ranging from gastroenteritis, typhoid fever to arthritis. Like most if not all infections, the early interaction between the host and the bacterium is characterised by very non-specific symptoms. These non-specific symptoms arise because the so-called innate immune system is activated by the infection. The purpose of this grant is to establish whether these non-specific symptoms, caused by the release of immunological homrones called cytokines, are essential to the development of an effective immune response which can protect against subsequent re-infection. This study has important implications for vaccines, of our understanding of how bacteria cause disease, and the role-capacity of the innate immune system in the development of immunity.Read moreRead less

Summary
Chronic inflammation is a central player in many common diseases, impacting on the health and well being of millions of Australians. By using innovative genomic approaches to build a map of all of the gene products involved in the inflammatory process, this project aims to identify which are the critical molecules that normally switch off inflammation. Our ultimate aim is to develop new approaches to treating inflammatory disease.
Lung infections are the most frequent triggers of asthma exacerbations. While different infections cause exacerbations by they all result in the same type of lung inflammation. Using novel disease models, we have identified key molecules involved in a range of viral and bacterial induced asthma exacerbations. We will define these shared pathways that link viral and bacterial-mediated asthma exacerbations, thus these studies will pave the way for the development of unified treatments.
TOLL LIKE RECEPTORS AGGRAVATE GLOMERULONEPHRITIS AND KIDNEY INJURY IN RENAL VASCULITIS

Summary
Anti neutrophil cytoplasmic antibody associated vasculitis (AAV) is a significant cause of morbidity and mortality. My thesis will explore the role of Toll Like Receptor (TLR) 2 and TLR9 in the initiation and pathogenesis of AAV and the therapeutic potential of TLR2/9 inhibitors. I will use both a murine experimental model and human kidney biopsy samples in this work. My thesis will further define the critical molecular events that underlie the disease whilst addressing potential new therapies.
Inflammasome Sensors And Immune Protection Against Tumorigenesis

Summary
Intestinal cancer is a leading cause of death in Australia and worldwide. Defects in the immune system can lead to the development of intestinal cancer. In this project, we will investigate the critical role of an immune sensor in inhibiting the development of intestinal cancer. This project will provide new insights into the interplay between the immune system and cancer biology and will potentially inform the development of new immunotherapies.
Inflammasome Function In Gastrointestinal Immunity And Inflammation

Summary
The immune system in the gut provides a vital defence against microbes. If these defences are ineffective we become infected leading to gastroenteritis, a major cause of death in the third world and hospitalisation in developed countries. Conversely, excessive or inappropriate activation of these defences can cause inflammatory disease. This project will investigate microbial detection in the gut, and aims to discover new, more effective ways to treat gastrointestinal infection and inflammation.
Defining The In Vivo Contribution Of Leukocyte Extracellular Traps To Infective Disease

Summary
Neutrophils are the white blood cells that protect against infection. A surprising protective neutrophil behaviour was recently described – neutrophils can pack up their internal DNA and antimicrobial enzymes and explosively release them into their surrounds, forming a “Neutrophil Extracellular Trap” (NET). This project uses zebrafish built have fluorescent neutrophils to study NET release in living animals. We will learn how NETs control infection and what goes wrong when NETs cause disease.
