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.
New approaches for screening cereal germplasm for enhanced microbial pathogen resistance and desirable grain texture. The trait of grain hardness (texture) is of significance to the Australian infrastructure, as exports of hard wheat contribute over 5 billion dollars per year on average to the national economy and hard wheats are also important for domestic usage. The genes responsible for grain texture also impart resistance to bacterial and fungal pathogens which can cause extensive damage. ....New approaches for screening cereal germplasm for enhanced microbial pathogen resistance and desirable grain texture. The trait of grain hardness (texture) is of significance to the Australian infrastructure, as exports of hard wheat contribute over 5 billion dollars per year on average to the national economy and hard wheats are also important for domestic usage. The genes responsible for grain texture also impart resistance to bacterial and fungal pathogens which can cause extensive damage. However, the Australian gene pool has very limited genetic diversity in grain textures and thus possibly in pathogen resistance. The project will work out the science behind these two traits and identify lines with new variants of textures and pathogen resistances, thus greatly benefiting the national infrastructure and local primary industries.Read moreRead less

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
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.

Chemo-sensation in Ascaris infection. This project aims to show the role of chemo-sensation as an equally important target for worm control, and explore pathways to prevent infection. Parasitic worms cost global food/textile industry more than $100 billion dollars per year, and cause disease in more than 1 billion people and domesticated animals world-wide.

Parasitic worms cost global food/textile industry more than $100 billion dollars per year, and cause disease in more than 1 billion people and domesticated animals world-wide. This project will use a combination of imaging, systems biology, chemical biology and microfluidic methods to provide significant benefits, such as exploring Ascaris chemo-sensation during larval migration, identify the key host queues and parasite genes regulating this process, and probe helminth chemosensation as a novel target for anti-parasitic treatments.Read moreRead less
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.

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

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
