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.

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
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.

Summary
Subversion of innate immune responses by pathogenic Escherichia coli. This project will determine how bacteria that cause diarrhoeal diseases prevent the immune system from signalling efficiently. It will provide important information not only about how the bacteria establish disease, but also provide insight into the host response in the early stages of infection.

An advanced in vivo imaging facility: This project will establish an advanced In Vivo Imaging Facility (IVIF) for examining host-microbe interactions and associated immunological processes within the context of the numerous infectious disease models within the University of Melbourne and associated collaborators. The Zeiss LSM 7MP 2-photon imaging system will provide enhanced capacity to directly visualise cellular and molecular events in real time, with greater sensitivity and in a broader range of tissues and organs. This will provide the opportunity for novel insights into numerous immunological and host-microbe interactions.Read moreRead less
Mechanisms connecting diet, metabolism, gut microbiota and immunity. This project will identify the role of short chain fatty acids and the G-protein coupled receptor (GPR43) in regulating immune responses. This could explain how diet affects immune responses and also how certain bacteria in the gut provide benefits for immune defence.
Exploiting the lymphatic system for next generation vaccine development . Vaccination is the most successful and cost-effective means of combating infectious diseases. This project will look at how vaccine adjuvants work and will help the development of new vaccines against infections in both animals and man. It will also promote the training of Australian scientists in the field of vaccine research and development.
