Development of an anti-Chlamydia vaccine for the koala. The koala is one of Australia's main icons and a major drawcard for tourists. However, it suffers from debilitating disease due to the bacterium Chlamydia, which can lead to severe conjunctivitis, eventual blindness in both sexes, and the females develop untreatable cysts and can become infertile. This project will develop a Chlamydia vaccine to be administered to healthy and diseased koalas in zoos, sanctuaries, koala care centres, relocat ....Development of an anti-Chlamydia vaccine for the koala. The koala is one of Australia's main icons and a major drawcard for tourists. However, it suffers from debilitating disease due to the bacterium Chlamydia, which can lead to severe conjunctivitis, eventual blindness in both sexes, and the females develop untreatable cysts and can become infertile. This project will develop a Chlamydia vaccine to be administered to healthy and diseased koalas in zoos, sanctuaries, koala care centres, relocation programs and eventually perhaps even wild populations. The vaccine findings may also be transferable to other animals and may also even assist the development of a human Chlamydia vaccine.Read moreRead less
Development of an effective vaccine for chlamydial infection: optimisation of a non-toxic cholera toxin-based adjuvant to generate a protective mucosal response. Chlamydial genital infections are the most common sexually transmitted infection in Australia and the world and impose a major health burden on the community. Chlamydial infections are also associated with cardiovascular disease, Australia's biggest killer and asthma, another condition that has increased significantly in prevalence in t ....Development of an effective vaccine for chlamydial infection: optimisation of a non-toxic cholera toxin-based adjuvant to generate a protective mucosal response. Chlamydial genital infections are the most common sexually transmitted infection in Australia and the world and impose a major health burden on the community. Chlamydial infections are also associated with cardiovascular disease, Australia's biggest killer and asthma, another condition that has increased significantly in prevalence in the past 10 years. This project will evaluate the effectiveness of a new adjuvant as a first step towards the development of a vaccine to target these important infections.Read moreRead less
Foreign DNA is a danger signal for mammalian cells. This project investigates how cells normally respond to foreign DNA, and is relevant to understanding how the body fights infections, particularly by viruses. The results will help us to design more effective treatments for infectious disease. Studying responses to DNA will also promote the design of new treatments for the autoimmune disease lupus, and help improve technologies or treatments where DNA is introduced into cells or tissues. This ....Foreign DNA is a danger signal for mammalian cells. This project investigates how cells normally respond to foreign DNA, and is relevant to understanding how the body fights infections, particularly by viruses. The results will help us to design more effective treatments for infectious disease. Studying responses to DNA will also promote the design of new treatments for the autoimmune disease lupus, and help improve technologies or treatments where DNA is introduced into cells or tissues. This includes gene therapy, new strategies for vaccination, and the production of proteins as drugs by biotechnology. The project will promote National Research Priorities in the areas of preventative healthcare, ageing well ageing productively, breakthrough science and new technologies.Read moreRead less

Summary
Lipopolysaccharide-induced macrophage extracellular traps in host defence. The innate immune system is the first line of defence against invading microbes. Macrophages are key innate immune cells that deploy antimicrobial responses to clear infection and restore health. There are many critical unanswered questions on the molecular mechanisms that drive macrophage inflammatory and antimicrobial pathways.

The innate immune system is the first line of defence against invading microbes. Macrophages are key innate immune cells that deploy antimicrobial responses to clear infection and restore health. There are many critical unanswered questions on the molecular mechanisms that drive macrophage inflammatory and antimicrobial pathways. This project aims to elucidate a novel inflammatory mechanism that immobilises and kills invading bacteria via newly discovered structures made by dying macrophages called extracellular traps. Insight we gain by interrogating this immune cell signalling pathway, called the non-canonical inflammasome, will add valuable knowledge to our fundamental understanding of mammalian inflammation and anti-microbial responses

Toll-like receptors in infectious and inflammatory diseases: the double-edged sword of innate immunity. The innate immune system is the first line of defence against invading microorganisms. This project will explore the role of specific innate immune genes in the control of infections and the development of inflammatory diseases.
Inflammasomes: molecular drivers of anti-microbial defence. The innate immune system is the body’s first line of defence against infection, but also drives unhealthy inflammation. Families of innate immune receptors, such as nucleotide-binding oligomerisation domain (NOD-like Receptors), were recently discovered to control both anti-microbial defence and unhealthy inflammation. This project will characterise the basic biology of NOD-like Receptors at the molecular, cellular and organismal levels ....Inflammasomes: molecular drivers of anti-microbial defence.

Families of innate immune receptors, such as nucleotide-binding oligomerisation domain (NOD-like Receptors), were recently discovered to control both anti-microbial defence and unhealthy inflammation. This project will characterise the basic biology of NOD-like Receptors at the molecular, cellular and organismal levels, and will thereby lead to a greater understanding of the fundamental biological pathways controlling inflammation and defence against infection. This may ultimately lead to commercial opportunities for treating infection and chronic inflammation.Read moreRead less
Combating invading DNA: a process conserved in evolution? Cells of our body defend against foreign genetic material, or DNA, which indicates an infection or invading DNA capable of causing mutation. These defences are so important that several layers have developed during evolution, and this project compares the responses of different organisms to foreign DNA.
