An interdisciplinary approach to host-pathogen interactions in infection. This project aims to understand the molecular and cellular interactions between host and parasite, as well as providing a quantitative framework for analysing infection dynamics in other systems. Infection involves a complex interaction between the host and the parasite, which is very dynamic and therefore difficult to study by traditional sampling and analysis approaches. This project has combined mathematical modelling w ....An interdisciplinary approach to host-pathogen interactions in infection. This project aims to understand the molecular and cellular interactions between host and parasite, as well as providing a quantitative framework for analysing infection dynamics in other systems. Infection involves a complex interaction between the host and the parasite, which is very dynamic and therefore difficult to study by traditional sampling and analysis approaches. This project has combined mathematical modelling with a novel experimental protocol to allow the study of kinetics of parasite replication in vivo. Expected outcomes will provide significant benefits, such as new avenues for vaccination and immune intervention.Read moreRead less
Translating pharmacokinetic and pharmacodynamic data to better design new drugs for the treatment of Trypanosoma cruzi infection. New drugs to treat T. cruzi infection are urgently needed, however their design has been hampered by an incomplete understanding of complex host-parasite interactions, inadequate in vitro and in vivo tools to rigorously define activity during drug discovery, and a poor appreciation of concentration/effect relationships. This project aims to develop new and much needed ....Translating pharmacokinetic and pharmacodynamic data to better design new drugs for the treatment of Trypanosoma cruzi infection. New drugs to treat T. cruzi infection are urgently needed, however their design has been hampered by an incomplete understanding of complex host-parasite interactions, inadequate in vitro and in vivo tools to rigorously define activity during drug discovery, and a poor appreciation of concentration/effect relationships. This project aims to develop new and much needed in vitro methods to better define the kinetic and dynamic activity of new drug candidates, and will provide a rational basis for translating this information into lengthy animal models of T. cruzi infection. The outcome aims to be rationally designed drug candidates that are available in a shorter period of time and are suitable for further development.Read moreRead less
How auto-transporter proteins mediate bacterial interactions. This project aims to investigate the structure-function relationships that underpin key auto-transporter roles in bacterial cell adhesion, aggregation and biofilm formation. Auto-transporter proteins are extremely common in bacteria where they play a central role in controlling bacterial interactions with other bacteria, with human cells, and with surfaces. This project will define the molecular mechanisms underlying these processes. ....How auto-transporter proteins mediate bacterial interactions.

Auto-transporter proteins are extremely common in bacteria where they play a central role in controlling bacterial interactions with other bacteria, with human cells, and with surfaces. This project will define the molecular mechanisms underlying these processes. This will have significant benefits, such as providing the basis for the development of approaches to block auto-transporter functions that contribute to the establishment of persistent and difficult to treat bacterial infections.Read moreRead less

New drugs against parasitic nematodes of livestock animals. This project aims to develop an innovative technology platform to deliver novel anti-infectives as biotechnological outcomes, using postgenomics, computing and chemistry. Advanced molecular, computer and chemistry technologies provide unprecedented opportunities to design radically new interventions against socioeconomically important infectious diseases affecting billions of animals worldwide. Anticipated outcomes are the design of radically new chemotherapies to control parasitic diseases, the translation of fundamental research into biotechnological outcomes, international visibility of Australian science, and a solid skills- and knowledge-base in veterinary drug development.Read moreRead less
Unraveling autotransporter function in bacterial aggregates and biofilms. Autotransporters are a large family of bacterial proteins that play a central role in pathogenesis. They promote the formation of cell clusters and biofilms, which are mechanisms for bacterial resistance to host immune factors and antibiotics. Currently, the precise mode of action of autotransporters is unknown. This project will examine the interplay between the structure and function of key autotransporter proteins. It ....Unraveling autotransporter function in bacterial aggregates and biofilms. Autotransporters are a large family of bacterial proteins that play a central role in pathogenesis. They promote the formation of cell clusters and biofilms, which are mechanisms for bacterial resistance to host immune factors and antibiotics. Currently, the precise mode of action of autotransporters is unknown. This project will examine the interplay between the structure and function of key autotransporter proteins. It is expected that the outcomes of this research will establish how these proteins mediate aggregation and biofilm formation. It may also provide three-dimensional structures of proteins that are strongly immunogenic and may represent targets for future vaccine design, as well as identify molecules that inhibit autotransporter function.Read moreRead less
New guardians of the mucosa: Molecular characterisation of M cell biology. We aim to completely define the cellular and molecular biology of gut and lung M cells for the first time. We will elucidate how they develop, are regulated and function at a molecular level, and how M cells maintain normal gut and lung tissues and induce immune responses to protect against microbial challenges. In the future, the new insights will be essential pre-requisites for the development of mucosal-based intervent ....New guardians of the mucosa: Molecular characterisation of M cell biology. We aim to completely define the cellular and molecular biology of gut and lung M cells for the first time. We will elucidate how they develop, are regulated and function at a molecular level, and how M cells maintain normal gut and lung tissues and induce immune responses to protect against microbial challenges. In the future, the new insights will be essential pre-requisites for the development of mucosal-based interventions and vaccines that protect the gut and lung from infectious and inflammatory issues. The harnessing of effective immune responses to control such challenges, are of enormous fundamental and long-standing biological interest, and are amongst the most important areas of current scientific research.Read moreRead less

Summary
A high-throughput screening and sequencing facility for single cell genomics. Genomics has revolutionised biology, but for most microorganisms this revolution has not arrived because very few can be grown in pure culture. The single cell genomics facility will address this major bottleneck by allowing as little as a single cell in a clinical or environmental setting to be sequenced thereby accelerating new discoveries and outcomes.
Investigating the molecular basis of T-cell receptor cross-reactivity. This project will explore the basis of unexpected immune reactions whereby the immune system mistakes one molecular structure for another, a phenomenon known as cross-reactivity. This project will examine how often this is due to molecular mimicry, potentially explaining why immune T cells sometimes react inappropriately to different agents.
