Transport and innate immune properties of DNA in bacterial nano-sized vesicles. All types of living organisms release nano-sized membrane vesicles or “blebs” which they use for intercellular communication and transport of molecules. This project will determine how bacteria package DNA within these vesicles, how this DNA is transported into host cells and how it triggers immune responses in these cells.

Summary
Applying cutting edge methods to grow bacteria from the human gut, we have identified three species, two previously unknown, that are found in many inflammatory diseases including Inflammatory bowel disease, colorectal cancer and in cancer immunotherapy patients who experience colitis. By characterizing these bacteria and the immune response in human cells we are seeking to discover novel targetted methods to prevent colitis and gastrointestinal inflammation.

Summary
Naturally occurring bacteria play an important role in determining patient disease susceptibility, disease progression and ultimately, disease outcome. Over 1000 species of bacteria, contributing 10 times as many cells as found within a single individual. This project seeks to understand these communities, how they confer resistance to infection and how they can be manipulated, both naturally and through controlled introduction of bacteria to prevent disease or improve disease outcome.
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.
Sterile inflammation as a determinant of adaptive immunity. When we injure ourselves, the site of injury becomes inflamed, which may help healing or cause trouble. This project aims to understand how the normal response to injury is controlled and why the process may sometimes go wrong.

Summary
The liver is important for both digestion and immunity. Given these opposing functions, the liver must exert control points that prevent the immune system from recognising food products. We have now identified a new molecular target that controls the development of immune cells in the liver.
Immune-imprinting nanoparticles (iNPs). This research promises new classes of immune-imprinting, biodegradable nanoparticles (iNPs) with anti-inflammatory properties. The engineering of such particles requires fundamental understanding of their properties that enable specific cellular interactions to regulate immunity with new anti-inflammatory pathways. For pulmonary delivery, spray-dried amino acid microspheres with tailored surfaces as carriers can be generated using the innovative microfluid ....Immune-imprinting nanoparticles (iNPs). This research promises new classes of immune-imprinting, biodegradable nanoparticles (iNPs) with anti-inflammatory properties. The engineering of such particles requires fundamental understanding of their properties that enable specific cellular interactions to regulate immunity with new anti-inflammatory pathways. For pulmonary delivery, spray-dried amino acid microspheres with tailored surfaces as carriers can be generated using the innovative microfluidic drying approach. The potential applications of iNPs are wide-ranging and are not restricted to pulmonary targeting. The potential commercial implications for Australia's emerging biopharmaceutical industry are substantial.Read moreRead less
Histone deacetylase functions in immune cells. This project aims to define how an enzyme (a histone deacetylase) enables innate immune cells (macrophages) to respond to specific danger signals, such as those activating Toll-like Receptors. To identify processes that provide specificity to signal transduction pathways, this project will characterise protein targets and biological functions of a specific class IIa histone deacetylase in macrophages. This project expects to result in an understandi ....Histone deacetylase functions in immune cells.

To identify processes that provide specificity to signal transduction pathways, this project will characterise protein targets and biological functions of a specific class IIa histone deacetylase in macrophages. This project expects to result in an understanding of histone deacetylases and protein deacetylation in immune cell responses which can be harnessed to manipulate cell functions for basic science and biotechnology uses.Read moreRead less
Analysing the protective role of platelets during malaria infection. Platelets protect the host during malarial infection. This project aims to study how platelets kill the malaria parasite by investigating the role of host molecules and their potential as novel antimalarial agents. The role of platelets in the pathogenesis of cerebral malaria syndrome will also be investigated.
Structural and functional studies of a Tripartite Motif-Containing Protein. This project will study a fundamental process that is crucial to the regulation of almost all cellular processes. The dysfunction of this process can lead to cancer, neurodegenerative and immunological disorders. The outcome will be an advancement in knowledgebase at the most fundamental level.
