Molecular basis of the antifungal and antimalarial activity of a plant defensin. The plant defensin NaD1 has potent inhibitory activity against a number of agronomically important fungal pathogens. These species are major pathogens of cotton and other important agricultural crops such as canola and potatoes. These pathogens cause serious economic losses and threaten the future of the cotton industry in Australia. NaD1 also has potential as a new antibiotic for treatment of infections in human ....Molecular basis of the antifungal and antimalarial activity of a plant defensin.

Regulation of local lymphocyte trafficking and its role during infection. The study of early immune responses will contribute to the development of better vaccination strategies. In particular it will contribute by helping to understand the essential differences between reactogenicity and immunogenicity and how this relates to adjuvants. Using this understanding it will be possible to develop novel adjuvants that induce appropriate immunity with minimal side effects.
An investigation into Infection, Immunity & Rational Drug Design. The human population is constantly under threat of microbial attack. The survival of our species reflects a delicate balance between infection and immunity. Whether an individual mounts an effective immune response or succumbs to microbial infection is critically dependent on host proteins interacting effectively with microbial antigens, versus microbes developing sophisticated strategies of invasion and immune evasion. This pr ....An investigation into Infection, Immunity & Rational Drug Design. The human population is constantly under threat of microbial attack. The survival of our species reflects a delicate balance between infection and immunity. Whether an individual mounts an effective immune response or succumbs to microbial infection is critically dependent on host proteins interacting effectively with microbial antigens, versus microbes developing sophisticated strategies of invasion and immune evasion. This proposal will provide fundamental advancement of knowledge in the areas of infection and immunity. The information gleaned from this research will lead to the rational development of therapeutics. Consequently, the research will potentially have an enormous global impact in the area of biomedical health.Read moreRead less
Characterization of metabolic networks in a microbial pathogen. New methods are needed to understand complex cellular processes such as metabolism. This proposal will support the development of methods in metabolite profiling and flux analysis that provide a global view of metabolic networks in cells and complement other profiling approaches, such as proteomics and transcriptomics. The development of these approaches (collectively termed Systems Biology) is essential for maintaining Australia sc ....Characterization of metabolic networks in a microbial pathogen.

The development of these approaches (collectively termed Systems Biology) is essential for maintaining Australia science at the forefront of international efforts (National Research Priority 3; Breakthrough science). This project will also directly contribute to our understanding of metabolism of an important human pathogen and provide training to young Australian scientists.Read moreRead less

Summary
Pushing the limits of fluorescence microscopy with adaptive optics. This project aims to establish an adaptive optics, super-resolution optical microscopy facility to image cellular events with the highest possible spatial resolution, in a whole cell or tissue context. Sophisticated computer-controlled deformable mirrors will be used to correct the way light is distorted as it passes through specimens, thereby overcoming aberrations found in thick and complex samples. This adaptive optics system ....Pushing the limits of fluorescence microscopy with adaptive optics. This project aims to establish an adaptive optics, super-resolution optical microscopy facility to image cellular events with the highest possible spatial resolution, in a whole cell or tissue context. Sophisticated computer-controlled deformable mirrors will be used to correct the way light is distorted as it passes through specimens, thereby overcoming aberrations found in thick and complex samples. This adaptive optics system will enable researchers to study complex behaviour of biological specimens, at the optical resolution limit in plant and animal tissues, leading to basic biology and biotechnology outcomes in biofuels, biomaterials and biomedicines.Read moreRead less

Summary
Export of effector proteins by P. falciparum to the infected red blood cell. Infection by the malaria parasite has lethal consequences for humans. The parasite exports hundreds of proteins via a translocon to commandeer the red blood cell. This project aims to determine the function of one of the major translocon components and determine if it is a viable target for anti-malarial drug development.
Evolution of AB5 toxins. The proposed research program, using the combination of structural biology and cellular biology will provide insight into the evolution of AB5 toxins. This study will not only improve our fundamental understanding how pathogens evolve to invade hosts but could lead to the rational design of antimicrobials. The knowledge gained will increase Australia's international research profile.
Sphingosine-1-phosphate receptor 5: a novel regulator of T cell immunity. T cells provide critical immune protection against infection and cancer. However, the pathways that regulate these immune cells are not fully understood. T cells express a molecule called S1P5 that has an unknown function in these cells. In this proposal, we reveal new evidence that this molecule is an unappreciated and crucial regulator of T cell behaviour. Using state-of-the-art techniques and novel genetic tools, this p ....Sphingosine-1-phosphate receptor 5: a novel regulator of T cell immunity. T cells provide critical immune protection against infection and cancer. However, the pathways that regulate these immune cells are not fully understood. T cells express a molecule called S1P5 that has an unknown function in these cells. In this proposal, we reveal new evidence that this molecule is an unappreciated and crucial regulator of T cell behaviour. Using state-of-the-art techniques and novel genetic tools, this project aims to discover the involvement of S1P5 in the immune response, and determine how S1P5 can be controlled to enhance protective T cell immunity. The expected outcomes are to generate fundamental new knowledge that will have significance for regulation of the immune response. Read moreRead less
Drug targets in malaria parasites. Malaria is rampant throughout our Region and hinders the economies of our neighbours reducing regional prosperity and stability.

Malaria is rampant throughout our Region and hinders the economies of our neighbours reducing regional prosperity and stability. Australian security and aid personnel deployed in the Region contract malaria infections and global warming could bring malaria-carrying mosquitoes south to Sydney. Australia is pre-eminent in malaria research, making lead discoveries in vaccine and drug development. However, we lack crucial resources to study the parasite in the mosquito phase of its life cycle. The Federation Fellowship will create a malaria mosquito facility to redress this crucial gap in our capability. The Fellowship will double as foreign aid investment by enhancing our capacity to protect ourselves as well as supporting our neighbours.Read moreRead less

Pathogen detection in mammals. This project aims to study the role of a host molecule in immune protection. Multicellular organisms need to recognise pathogens to initiate immune protection. To do this, pathogen-specific molecules are presented to the immune system causing activation. Recently a mode of pathogen recognition was discovered in mammals. As microbes synthesise essential vitamins, they release tell-tale metabolite by-products, which a host molecule called MR1 captures and presents to ....Pathogen detection in mammals. This project aims to study the role of a host molecule in immune protection. Multicellular organisms need to recognise pathogens to initiate immune protection. To do this, pathogen-specific molecules are presented to the immune system causing activation. Recently a mode of pathogen recognition was discovered in mammals. As microbes synthesise essential vitamins, they release tell-tale metabolite by-products, which a host molecule called MR1 captures and presents to white blood cells. However, it is not understood how MR1 accomplishes this, the cellular machinery required, or how the metabolites are guided to MR1. Understanding this process is expected to explain microbial pathogen recognition.Read moreRead less
