Summary
Plasmepsin V and PTEX are essential proteins for malaria parasites to grow inside red blood cells. These proteins control the export of parasite proteins into red cells, causing disease. Before red blood cells are infected, parasites invade liver cells. Plasmepsin V and PTEX are expressed during liver infection but their function is currently unknown. We hypothesise that they allow parasites to export proteins into liver cells in order to survive and, thus, are antimalarial drug targets.
Identifying Metabolic Pathways In Leishmania Parasites And Their Host Cells Required For Virulence

Funding Amount
$989,110.00
Summary
Our lack of understanding of microbial metabolism in infected animal tissues has hindered the development of effective therapies. This is particularly true for many parasitic diseases, including Leishmania spp that cause devastating disease throughout the tropics. We will utilize a range of innovative analytical and genetic approaches to identify metabolic pathway in Leishmania parasites and infected host cells that are required for virulence and are potential drug targets.
Interdisciplinary Insights Into The Rational Design Of Malaria Therapy And Vaccines

Summary
Malaria is a global health concern with almost half a million deaths annually. There is an urgent need for a highly effective malaria vaccine and new antimalarials. However, despite decades of research into this pathogen, our understanding of what causes illness in a person and how immunity operates is limited. This project will use a mathematical modelling approach to provide a new way to understand infection, as a rapidly changing and intricate process.
Plasmodium vivax is a parasite that invades the youngest of human red blood cells. Our work will reveal how this malaria parasite enters our blood cells and the molecular mechanisms that allows successful invasion. This proposal will redefine our understanding of P. vivax invasion and explore novel ways to block its entry into red blood cells and therefore prevent malaria infection.
Novel Serological Tools To Aid Malaria Elimination In The Asia-Pacific

Summary
In 2014 Asia-Pacific leaders pledged a malaria free Asia-Pacific by 2030. We will contribute to this goal by developing novel antibody detection tests that can identify people with current and recent past infections. We will then evaluate the utility of these tests both in mass screening and treatment programs and for the rapid delineation of areas where transmission persists from those where it has been eliminated. This will address two major roadblocks to malaria elimination in our region.
INSIDE THE SKIN: UNDERSTANDING DIFFERENT HOST RESPONSES IN SCABIES

Summary
Scabies is an underlying cause of poor health in indigenous communities worldwide. Crusted scabies is a poorly understood, life-threatening form of the disease compromising the success of community control strategies. This research compares the immune response in the skin of scabies patients, and in a world-first animal model of human scabies. This will reveal specific immune defects predisposing to disease, ultimately resulting in improved skin health for disadvantaged communities
Helminth Secreted Proteins – From Anthelmintic Vaccines To Therapies For Autoimmunity
Funder

Funding Amount
$739,893.00
Summary
Human helminths (worms) cause chronic disease in developing countries, yet their disappearance from developed countries has been accompanied by an increase in the prevalence of autoimmune and allergic diseases. My resesarch focuses on the proteins these worms secrete and their use in (1) the development of anthelmintic vaccines, and (2) the development of novel anti-inflammatory molecules to treat autoimmunity, particularly diseases affecting the gut.
Apical Membrane Proteins As Targets For A Schistosomiasis Vaccine

Funding Amount
$480,459.00
Summary
Schsitosomiasis is a chronic neglected tropical disease for which there is currently no vaccine. A vaccine is sorely needed to control this parasite. This proposal seeks to identify molecules from the outer surface of the parasite which are recognised by the immune system of people from Brazil who are resistant to schistosomiasis. Molecules identified in this manner will be tested as vaccines in an animal model of schistosomiasis, and ranked based on their performances to enter human trials.
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.

Funding Amount
$375,000.00
Summary
Transmission dynamics modelling of zoonotic neglected tropical diseases. This project will develop mathematical models to simulate zoonotic disease transmission and control. Results will provide novel insight for policy makers into effective interventions for schistosomiasis, echinococcosis and clonorchiasis, as well as provide a methodological platform for adaptation to other zoonotic emerging and re-emerging diseases.
