The cellular basis of sex-specific responses to virus infection. This project aims to explore how the sex of cells impacts virus infections in culture. To date, the sex of cells in culture has been overlooked as an important source of biological variability, but may be found to affect basic science through to anti-viral drug discovery. Using a model in which a virus can be adapted to grow better in cells of a single sex, this project expects to generate new knowledge about how sex differences im ....The cellular basis of sex-specific responses to virus infection.

Using a model in which a virus can be adapted to grow better in cells of a single sex, this project expects to generate new knowledge about how sex differences impact virus-host interactions. This project expects to provide new insights into sex-based differences in how cells detect and respond to virus infection, and the extent to which the sex of cells impacts viruses in general.Read moreRead less
An Open Source Approach to Understanding an Important Parasite Ion Pump. This project plans to synthesise new compounds that bind the protein ATP4, an essential ion pump in the malaria parasite. It plans to generate a three-dimensional map to understand how these compounds stop ATP4 from working. Several promising new medicines for malaria target ATP4, yet we do not understand properly how they do so. The project’s intended aims will be achieved using new methods in synthetic chemistry and membr ....An Open Source Approach to Understanding an Important Parasite Ion Pump.

The project’s intended aims will be achieved using new methods in synthetic chemistry and membrane biology, and by leveraging global scientific inputs through online research methods allowing anyone to participate.Read moreRead less
Composition, assembly and functions of the pellicle of apicomplexan parasites: a structure pivotal to disease transmission and progression. Apicomplexan parasites are successful agents of disease (e.g. malaria) due to their superb ability to quickly invade host cells and generate many more parasites. This project will study the dedicated structures beneath the parasite cell covering that are responsible for these abilities to help refine strategies for combating apicomplexan diseases.

Summary
Collaborative high bio-containment immunological research facility. Emerging infectious diseases are a serious threat to animals and humans, with most new human infections originating in animals. Our capacity to study these infections and their effects on the immune system is limited. This Facility will provide core equipment for analysis of immune responses to infection at the highest levels of bio-containment.
Signalling pathways for sexual differentiation of apicomplexan parasites. This project aims to study the sexual development of apicomplexan parasites, which cause major diseases in humans, livestock and wildlife, including malaria. Only sexually differentiated cells can survive in the mosquito vector and hence this development is essential for the parasite's life-cycle. This project will employ a new approach that separates female from male parasites, thus enabling new information to be gleaned ....Signalling pathways for sexual differentiation of apicomplexan parasites. This project aims to study the sexual development of apicomplexan parasites, which cause major diseases in humans, livestock and wildlife, including malaria. Only sexually differentiated cells can survive in the mosquito vector and hence this development is essential for the parasite's life-cycle. This project will employ a new approach that separates female from male parasites, thus enabling new information to be gleaned about the development of these parasites. The expected outcomes are an understanding of the mechanisms of sexual differentiation and a functional characterisation of novel sex-specific molecules. This will provide significant benefits, such as pivotal prerequisites for new approaches to parasite intervention.Read moreRead less

Mathematical models of diseases with complex transmission routes. This project aims to model diseases that spread via a mixture of routes including food, water, the environment, and direct spread between individuals. Key diseases include: avian influenza, which causes massive disruption to the poultry industry; gastroenteritis, which costs Australia $1,250 million each year; and leptospirosis, which causes one million severe illnesses each year globally. This project will develop mathematical a ....Mathematical models of diseases with complex transmission routes.

Key diseases include: avian influenza, which causes massive disruption to the poultry industry; gastroenteritis, which costs Australia $1,250 million each year; and leptospirosis, which causes one million severe illnesses each year globally. This project will develop mathematical and statistical tools to better estimate risk, analyse outbreak data, and provide guidance for disease control. This research will improve policy and enhance our ability to respond to disease outbreaks.Read moreRead less

Ion regulation in Apicomplexan parasites. This project aims to determine how Apicomplexan parasites regulate their sodium and chloride levels to support the development of new parasite control measures.

This project aims to determine how Apicomplexan parasites regulate their sodium and chloride levels to support the development of new parasite control measures. Apicomplexan parasites cause devastating animal and human diseases. Little is known about the physiology of these parasites, and options for controlling them are few. Apicomplexan parasites must precisely control their internal ion compositions in order to survive, but how they do so is not understood. Recent work has identified a unique Apicomplexan sodium transporter and revealed a number of chloride transporter candidates. Using a combination of molecular biology and physiological techniques, this project aims to characterise the Apicomplexan sodium transporter in detail and elucidate the molecular mechanisms of chloride transport.Read moreRead less
Regulating nutrient uptake in intracellular parasites. Parasites impose a major economic and medical burden on human societies. In order to grow and reproduce, parasites scavenge nutrients from their animal or human hosts. As they move within and between hosts they encounter different levels of nutrients; how they adapt to these differences is poorly understood. This project aims to investigate the mechanisms by which the model parasite Toxoplasma senses and responds to the nutrients in its envi ....Regulating nutrient uptake in intracellular parasites. Parasites impose a major economic and medical burden on human societies. In order to grow and reproduce, parasites scavenge nutrients from their animal or human hosts. As they move within and between hosts they encounter different levels of nutrients; how they adapt to these differences is poorly understood. This project aims to investigate the mechanisms by which the model parasite Toxoplasma senses and responds to the nutrients in its environment, thereby shedding light on how they adapt to the different environments that they inhabit and, in the longer term, informing novel treatment strategies that aim to limit the parasites’ nutrient supply.Read moreRead less
