The biosynthesis of structural proteins in parasites. The socio-economic impact of parasitic diseases, in Australia and throughout the world, is enormous- they kill 2-3 million people per year and cost livestock industries billions of dollars per annum. Some are serious food and waterborne threats, such as the coccidia, because they are transmitted from person-to-person via the faecal-oral route, or via ingestion of contaminated water or food, or through the ingestion of cysts in raw or underco ....The biosynthesis of structural proteins in parasites. The socio-economic impact of parasitic diseases, in Australia and throughout the world, is enormous- they kill 2-3 million people per year and cost livestock industries billions of dollars per annum. Some are serious food and waterborne threats, such as the coccidia, because they are transmitted from person-to-person via the faecal-oral route, or via ingestion of contaminated water or food, or through the ingestion of cysts in raw or undercooked meat. They cause diarrhoea, which in some cases, can be life-threatening. We will understand how the coccidia protect themselves as they move from host to host and, through that understanding, develop new ways to control them and eliminate the suffering caused by parasitic diseases.Read moreRead less
Transcriptional control of antigenic variation in the malaria parasite Plasmodium falciparum. Malaria is a major health concern for the Australian Defence Personnel recently deployed in East Timor, Afghanistan and the Solomon Islands and is endemic in our immediate neighbours Indonesia and Papua New Guinea. Australia is susceptible to malaria and climate change could extend the mosquitos range to large population centres of Northern Australia causing malaria in Australia. This study would clarif ....Transcriptional control of antigenic variation in the malaria parasite Plasmodium falciparum. Malaria is a major health concern for the Australian Defence Personnel recently deployed in East Timor, Afghanistan and the Solomon Islands and is endemic in our immediate neighbours Indonesia and Papua New Guinea. Australia is susceptible to malaria and climate change could extend the mosquitos range to large population centres of Northern Australia causing malaria in Australia. This study would clarify how malaria parasites evade the host's immune response and help to protect Australia by providing drug targets for the control of this invasive disease.Read moreRead less
Validating protozoa-specific drug targets using peptides from biodiverse gene fragment libraries. Cryptosporidium and the trypanosomes are protozoan parasites, which have a global impact on the health, survival and economic development of millions of people and animals world wide. New therapies for the diseases they cause are urgently required. We describe a novel means of identifying protozoa-specific peptides that will inhibit the formation of essential protein complexes, which have no effect ....Validating protozoa-specific drug targets using peptides from biodiverse gene fragment libraries. Cryptosporidium and the trypanosomes are protozoan parasites, which have a global impact on the health, survival and economic development of millions of people and animals world wide. New therapies for the diseases they cause are urgently required. We describe a novel means of identifying protozoa-specific peptides that will inhibit the formation of essential protein complexes, which have no effect on the mammalian host. Candidate peptides will then be used to validate these protein complexes as new targets for the development of peptide-based therapeutic compounds. This project will validate novel targets for the development of new treatments for these diseases.Read moreRead less
Ion transport in the malaria parasite and parasitised erythrocyte. This work will contribute to the national research effort in parasitology (an area in which the ARC has established a Research Network), as well as laying the groundwork for subsequent efforts (not part of this grant) to develop new antimalarial strategies. Although not yet endemic in Australia, malaria is a serious problem in the local region and, as the major developed nation in the region Australia has an obligation to make ....Ion transport in the malaria parasite and parasitised erythrocyte.

Although not yet endemic in Australia, malaria is a serious problem in the local region and, as the major developed nation in the region Australia has an obligation to make a significant contribution to research in this area. The work proposed here will contribute to Australia's meeting this obligation.Read moreRead less
Amino acid transporters and the chloroquine resistance transporter of the intracellular malaria parasite. This work entails an ongoing collaboration between three independent research groups with highly complementary expertise and experience. It will make a significant contribution to the maintenance of Australia's scientific capabilities and training opportunities.

This work entails an ongoing collaboration between three independent research groups with highly complementary expertise and experience. It will make a significant contribution to the maintenance of Australia's scientific capabilities and training opportunities. The project will yield important insights into the biology of the causative agent of a major human disease, and the mechanism by which the malaria parasite has developed resistance to antimalarial drugs. Although not yet endemic in Australia, malaria is a serious problem in the local region and this work will help Australia meet its obligations to carry out high-quality research that advances our knowledge in this area.

The dynamics of viral latency in chronic infection. Although many acute infections can now be controlled, we still suffer from a large number of chronic infections such as HIV or herpes that cannot be eradicated. Many of these infections persist because they can lie dormant in a 'latent' state. How this latent state is established, and how long it lasts are important to understand if we want to control these infections. We have assembled a team of mathematicians, immunologists and virologists in ....The dynamics of viral latency in chronic infection. Although many acute infections can now be controlled, we still suffer from a large number of chronic infections such as HIV or herpes that cannot be eradicated. Many of these infections persist because they can lie dormant in a 'latent' state. How this latent state is established, and how long it lasts are important to understand if we want to control these infections. We have assembled a team of mathematicians, immunologists and virologists in order to study latent infection at the cellular level, and within infected monkeys. This will provide the first insights into the dynamics of latency - how these cells are produced and die - and should lead to novel approaches to controlling chronic infection.Read moreRead less
An Investigation of the Structure and Conformational Stability of a Membrane Associating Protein and its Petidic Ligands. The genome of the parasite most commonly responsible for fatal malaria will be completed this year. Structural elucidations of proteins identified from these genomic data will expedite the identification and classification of proteins synthesised by the parasite that might be developed as vaccines or as targets for anti-malarial therapeutics.

The genome of the parasite most commonly responsible for fatal malaria will be completed this year. Structural elucidations of proteins identified from these genomic data will expedite the identification and classification of proteins synthesised by the parasite that might be developed as vaccines or as targets for anti-malarial therapeutics. In this work, recent developments in structural biology will be employed to obtain the structure of a vaccine candidate and to identify environmental factors that influence the stability of this structure. A novel approach will be taken to determine the conformation of ligands bound to such proteins, which will provide a basis for the development of therapeutics.Read moreRead less
