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.
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.
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.
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.
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

An Automated Protein Nano-Crystallisation Facility. An automated protein nano-crystallisation facility:
The project aims to establish a high throughput protein nanocrystallisation and imaging facility for protein crystallography. Protein crystallography is an important field of biological research, however there are many proteins, such as integral membrane proteins and transient molecular complexes that are more challenging to crystallise.

The project aims to establish a high throughput protein nanocrystallisation and imaging facility for protein crystallography. Protein crystallography is an important field of biological research, however there are many proteins, such as integral membrane proteins and transient molecular complexes that are more challenging to crystallise. The facility aims to use state-of-the-art imaging and crystallisation techniques, including second order nonlinear imaging of chiral crystals (SONICC) imaging and lipid cubic phase approaches, to enable structural studies to be undertaken on challenging proteins. This information is often used for the rational development of therapeutics. The facility would support cutting-edge biological research In Australia.Read moreRead less
SNARE-mediated perforin and cytokine release in natural killer cells. Cytotoxic cells release toxic granules and cytokine messengers to kill pathogen infected and cancerous cells and to mount immune responses. This project will investigate different SNARE molecules that regulate the secretion of perforin from granules and cytokines from other carriers, assisting in the understanding of complex but essential cellular pathways.

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.
The regulation of anti-viral immunity by host and viral proteins. Anti-viral immunity is initially triggered when specific immune sensors detect viral components within the cell. This project will use a combined functional/structural approach to investigate the specifics of immune activation by a pivotal immune sensor and use this information to understand how influenza A sabotages this specific immune response.
