Activation of invasion in Toxoplasma. Host cell invasion is critical for the establishment and maintenance of infection by the single-celled parasite Toxoplasma gondii, the causative agent of Toxoplasmosis. This project will use the latest molecular techniques to understand how invasion is activated and will define a new set of drug targets to treat Toxoplasmosis and related diseases.
Mechanisms of human immunodeficiency virus entry into cells. This project will develop an understanding of how human immunodeficiency virus (HIV) evolves in people to become better able to infect, and hence destroy, cells of the immune system. It is expected that new knowledge into how HIV alters the way it interacts with these cells will reveal insights for the design of vaccines, drugs and new diagnostic tests.
Immuno-epidemiological insights into the development of immunity to malaria and drug resistance. This project aims to better understand the maintenance and acquisition of immunity to malaria in high risk groups. It will also attempt to elucidate how immunity can interfere with the therapeutic efficacy of antimalarials, especially in the assessment of emerging drug resistance. The over-riding hypothesis is that differences in malaria transmission will lead to differential acquisition of immunity ....Immuno-epidemiological insights into the development of immunity to malaria and drug resistance. This project aims to better understand the maintenance and acquisition of immunity to malaria in high risk groups. It will also attempt to elucidate how immunity can interfere with the therapeutic efficacy of antimalarials, especially in the assessment of emerging drug resistance. The over-riding hypothesis is that differences in malaria transmission will lead to differential acquisition of immunity and efficacy of malaria interventions within and between populations. Understanding immunity to malaria is pivotal to develop new interventions, to understand the effectiveness of current malaria treatment and control programs to reduce the global burden of malarial 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.

Summary
Subversion of innate immune responses by pathogenic Escherichia coli. This project will determine how bacteria that cause diarrhoeal diseases prevent the immune system from signalling efficiently. It will provide important information not only about how the bacteria establish disease, but also provide insight into the host response in the early stages of infection.

Summary
Targeting cell death pathways in parasites. Schistosomiasis is a disease caused by parasitic worms. Due to the potential for drug resistance, new drugs are needed. This project aims to identify the components needed for parasite survival based on a cell death pathway in schistosomes. Neutralising the activities of these proteins should cause parasite death, providing a new treatment strategy.
Investigating the intercellular trafficking of proteins and RNA and its relevance to neurodegenerative diseases. Alzheimer's and prion diseases are neurodegenerative disorders associated with protein misfolding. This project brings together similar features of these diseases using novel cell- and animal-based studies to develop a greater understanding of the molecular basis of these disorders.
Molecular dissection of malaria parasite motility and host-cell invasion across the lifecycle. Malaria parasites move in a unique way, gliding across cell surfaces and infecting host cells using a unique molecular motor. This research aims to understand the molecular mechanics behind parasite movement and use this to develop novel drugs that might throw a spanner in the parasite motor, blocking movement and thereby preventing malaria disease.
Evolution of immunoregulatory networks: preventing autoimmunity at the expense of perpetuating chronicity in persistent infections. Chronic pathogens like HIV take advantage of human genes that regulate immune responses, which evolved to prevent autoimmunity, enabling them to evade eradication. This project defines the nature and interplays between these genes and will provide valuable clues as to how immunity can be manipulated to promote clearance of persistent infections.

Summary
An advanced flow cytometry facility for the Peter Doherty Institute. The establishment of a flow cytometry facility in the new Peter Doherty Institute for Infection and Immunity will enhance capacity to investigate immunity to a broad range of very serious diseases. This project will support researchers studying viral and bacterial infection as well as cancer and autoimmunity.
