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 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
Elucidating the post-transcriptional regulation of mast cell proteases. Mast cells (MCs) are immune cells that protect against pathogens but may induce deleterious inflammation. MC function is mediated by specific proteases that are pre-formed and stored in granules. These proteases have unique yet poorly understood mechanisms of regulation. The aim of the project is to use a novel suite of molecular tools and genetically modified mice to identify the critical regions of transcripts that post-tr ....Elucidating the post-transcriptional regulation of mast cell proteases.

These proteases have unique yet poorly understood mechanisms of regulation. The aim of the project is to use a novel suite of molecular tools and genetically modified mice to identify the critical regions of transcripts that post-transcriptionally regulate the production and storage of these proteins. The project aims to identify the RNA binding proteins, microRNAs and other novel factors that also regulate them. This is expected to elucidate the post-transcriptional mechanisms of regulation of MC proteases.Read moreRead less

Summary
Argonaute proteins and the mammalian antiviral response. Awarded the Nobel Prize for Medicine in 2006, RNA interference (RNAi) is a natural process that plants use to attack viruses. Humans possess all of the tools for RNAi, but whether it is used for antiviral defense is unknown. This project aims to uncover this immune process which will open new avenues to treat virus infections, from influenza to HIV.
A molecular and functional investigation of innate-like T cells of the immune system. This project will investigate innate-like T cells, which are at a crossroad between innate and adaptive immunity. A complete knowledge of the cellular function and balance of these cells will offer potential for new immunotherapies associated with infectious and autoimmune disorders.
Imaging the generation and recall of protective antiviral immune responses in vivo. Our understanding of the in vivo dynamics of cellular immune responses to infectious diseases is poor. This project will utilise advanced intravital imaging combined with novel tools to dissect the cellular events involved in the generation and recall of T cell responses to localised virus infection, combined with a detailed functional analysis of the lymphoid organ stroma.

Summary
Fluorescence microscopy with optical tweezers: imaging cellular responses. Life relies on the ability of our cells to receive and respond to signals with pinpoint accuracy, involving both chemical and mechanical signals. This equipment will allow scientists to expose cells to both types of signals and measure the response at an unprecedented level of accuracy for the first time.
Understanding T cell immunity induced by infection. We aim to understand how killer T cells are “programmed” upon activation and acquire their characteristic functions and how these are maintained into immunological memory. This proposal will provide insights important for the design and improvement of vaccine strategies to fight pathogens such as influenza, HIV and even tumors.

Summary
Defining the mechanisms of tissue-resident memory T cell development. We have recently identified a subset of T cells that reside at points of pathogen entry where they can effectively control infection. The ability of these T cells to offer local immunity has caused a paradigm shift in our view of how T cells protect against infection, drastically changing the way we think about designing T cell vaccines. This project aims to characterise this novel T cell subset, defining the fundamental requi ....Defining the mechanisms of tissue-resident memory T cell development.

The ability of these T cells to offer local immunity has caused a paradigm shift in our view of how T cells protect against infection, drastically changing the way we think about designing T cell vaccines. This project aims to characterise this novel T cell subset, defining the fundamental requirements for their formation and maintenance. This will lead to a greater understanding of their biology, which will be of significance for the development of novel vaccination strategies.Read moreRead less
