Chromatin barriers in Plasmodium falciparum gene regulation. Malaria is a major world disease that kills around 2 million people annually. The genome of the causative agent has now been completely sequenced, but we still know very little of how and why some genes are activated while their neighbours are turned off. I will study the DNA barriers that separate such genes, and the proteins that interact with these regions to better understand how genetic regulation functions in these parasites.

I will study the DNA barriers that separate such genes, and the proteins that interact with these regions to better understand how genetic regulation functions in these parasites. A better understanding of gene regulation in malaria parasites will help us to better combat the tricks utilised by this and other organisms to elude our immune systems.Read moreRead less

Host cell targets of bacterial virulence effectors. The research described in this proposal will result in a better understanding of the cell biology of host-pathogen interactions. We are in a unique position to analyze the importance of protein/protein interactions between bacterial virulence determinants and host cell proteins using a range of cell biology techniques to address the fundamental, molecular basis of the host-pathogen interaction. In addition we will construct a new genetic tool ....Host cell targets of bacterial virulence effectors. The research described in this proposal will result in a better understanding of the cell biology of host-pathogen interactions. We are in a unique position to analyze the importance of protein/protein interactions between bacterial virulence determinants and host cell proteins using a range of cell biology techniques to address the fundamental, molecular basis of the host-pathogen interaction. In addition we will construct a new genetic tool to identify novel bacterial virulence determinants. We anticipate that a greater knowledge of the factors that contribute to the host-pathogen interaction will provide new insights into the subversion of host cell processes by bacterial pathogens of animals, plants and humans.

New inhibitors of HIV based on cellular enzymes. Over 39 million people are infected with HIV worldwide. However, none of the most highly affected countries have yet reached the peak in AIDS-related illness and death, thus the global impact of HIV/AIDS will get significantly worse, before it gets better.
In Australia, HIV is again on the rise. Ironically, improved treatments that have extended life expectancy will cause the number of HIV infected Australians to rise for many years to come. ....New inhibitors of HIV based on cellular enzymes. Over 39 million people are infected with HIV worldwide. However, none of the most highly affected countries have yet reached the peak in AIDS-related illness and death, thus the global impact of HIV/AIDS will get significantly worse, before it gets better.
In Australia, HIV is again on the rise. Ironically, improved treatments that have extended life expectancy will cause the number of HIV infected Australians to rise for many years to come. Therefore many Australians will suffer from the combined impact of the AIDS illness itself, opportunistic infections, the side-effects of treatment and natural aging. We aim to develop new drugs to combat this disease to help people everywhere lead happier, healthier and more productive lives.Read moreRead less
Post-genomic investigation of the relict plastid and mitochondrion of malaria parasites. Malaria is a major global health problem. The malaria parasite has two substructures, a relict chloroplast and a mitochondrion, that are excellent targets for new and existing drugs. However, we do not know the key functions of these two compartments. The entire genetic blueprint (genome) is now available for the malaria parasite and I propose to determine exactly which parts of the genome service the rel ....Post-genomic investigation of the relict plastid and mitochondrion of malaria parasites. Malaria is a major global health problem. The malaria parasite has two substructures, a relict chloroplast and a mitochondrion, that are excellent targets for new and existing drugs. However, we do not know the key functions of these two compartments. The entire genetic blueprint (genome) is now available for the malaria parasite and I propose to determine exactly which parts of the genome service the relict chloroplast and mitochondria. This will sketch out a picture of their inner workings. Armed with this information we can take a rational approach to seeking an Achilles? Heel of malaria against which parasite-specific drugs can be developed.Read moreRead less
Transcriptional and epigenetic regulation of terminal lymphocyte differentiation and alterations of the same that lead to leukemia. In the developed world infection diseases are the number three killer behind heart disease and cancer, and huge financial effort is put into treatment and prevention. Despite this, results have often been disappointing. One cause of these poor outcomes is the lack of knowledge of how effective immune responses are generated.

In the developed world infection diseases are the number three killer behind heart disease and cancer, and huge financial effort is put into treatment and prevention. Despite this, results have often been disappointing. One cause of these poor outcomes is the lack of knowledge of how effective immune responses are generated. This project aims to better understand the processes that control the generation of protective lymphocytes. It will deliver information that may enable a more targeted approach to vaccine-development and treatments of infections. As defective differentiation can also be a cause of leukemia it may also lead to targets of cancer treatment.Read moreRead less
