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

Summary
We will investigate malaria, a parasitic disease that kills over 450,000 people a year. We will explore how the parasite identifies, invades and remodels the host cells in which it lives, scavenging nutrients and hiding from the immune system. We will characterize the proteins involved in these critical events, as they are potential targets for drugs. We will study how parasites cause disease and how the host responds to infection.
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
Probing sexual transformation of the human malaria parasite, Plasmodium falciparum, using novel imaging modalities. Malaria parasites adopt a characteristic banana shape prior to sexual recombination; without this shape change disease transmission via mosquitoes cannot occur. This project will use advanced imaging technologies to study sexual recombination of malaria with a view to preventing the millions of deaths due to malaria each year.
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

Summary
Three-dimensional cryo electron microscopy facility. The three-dimensional cryo-electron microscopy facility will let us visualise plants, pathogens and nanomachines with resolution not previously possible allowing us to see into cells and diseases with vastly more detail. Our world-class experts will provide regional and national researchers access to cutting-edge technology complementary to the Australian Synchrotron.
Investigating why malaria parasites have a unique translocon. This project aims to explore the mechanism that enables malaria parasites to thrive in their host cells. Parasites that cause the disease malaria reside inside erythrocytes, a very basic cell that lacks a vesicular trafficking pathway. To survive and thrive in this environment, the parasite has evolved a completely unique cell biological phenomenon termed PTEX to transport its proteins into the host cell. The aim of this project is to ....Investigating why malaria parasites have a unique translocon.

Parasites that cause the disease malaria reside inside erythrocytes, a very basic cell that lacks a vesicular trafficking pathway. To survive and thrive in this environment, the parasite has evolved a completely unique cell biological phenomenon termed PTEX to transport its proteins into the host cell. The aim of this project is to determine how this novel PTEX machinery exports proteins into erythrocytes and whether PTEX is also required for parasite survival during the initial stages of a host infection when malaria reside in hepatocytes.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.
