Funding Amount
$763,409.00
Summary
Two powerful and complementary approaches to developing new drugs will be combined to target proteins that play key roles in malaria and other parasite and bacterial infections with the aim of developing new therapeutics. In addition, the potential of peptide toxins to treat autoimmune diseases such as multiple sclerosis, as well as chronic pain and other conditions, will be exploited to develop new drugs.
Novel Perspectives On The Function Of AB5 Toxin B Subunits

Summary
AB5 toxins are important virulence factors of pathogenic bacteria. They comprise pentameric B subunits that bind to target cell surfaces and catalytic A subunits that damage host cell functions. This proposal examines a new paradigm wherein the B subunits are significant contributors to cell damage. We will characterize the cytopathic properties of diverse B subunits, particularly those of emerging toxins. This will provide novel insights into pathogenesis and inform development of therapeutics.
Helicobacter Pylori VacA Toxin: Modulation Of Human Mitochondrial Function By A Bacterial Pathogen

Funding Amount
$508,003.00
Summary
This work will greatly further our understanding of how a bacterium, Helicobacter pylori, causes stomach ulcers and cancer. We will use cutting edge model systems to study the VacA toxin that is secreted from the bacteria and is targeted to human cells. We will examine where the toxin goes and how it affects our cells. It is expected that the improved understanding that will arise from this work will assist researchers to better devise drugs against this prevalent pathogen.
Perinatal Exposure To Household And Environmental Toxins And The Risk Of Asthma And Allergic Disease Up To 25 Years

Summary
Perinatal exposure to household and environmental toxins may increase asthma and allergic disease risk. Adverse exposures in this critical developmental window may have a marked and prolonged effect on health. A birth cohort of high-allergy risk children will be used to investigate the effect of common chemical exposures on the risk of asthma and allergic disease up to 25 years. This evidence could be used to inform guidelines on common household chemical exposures
Disease Burden, Risk Factors And Treatment Of Knowlesi Malaria

Summary
Plasmodium knowlesi is a form of monkey malaria recently found to also cause increasing numbers of natural infections in humans in South-East Asia. This research will describe the burden of P. knowlesi malaria in an area of Malaysian Borneo. The risk factors for acquiring P. knowlesi malaria will be assessed. Finally the optimal treatment for non-severe cases of P. knowlesi and P. vivax malaria will also be evaluated by comparing the 2 currently recommended anti-malarial medications in Malaysia.
A significant proportion of Australian children are at health risk due to environmental metal exposure. It is suspected that exposure to metals during the prenatal period can result in permanent impairment. Human studies are, however, limited by lack of biomarkers that accurately measure exposure at specific times of intrauterine development. We are proposing to develop a novel method that utilizes human primary teeth to provide a direct measure of metal exposure during foetal development.
Snake envenoming is a neglected tropical disease and results in numerous deaths, psychological problems and economic burden. Antivenoms aren't readily available in resource poor countries. The CRE will investigate the effects of venom and antivenom to improve understanding of human envenoming. It will also develop tests for early diagnosis of envenoming and undertake clinical trials of antivenom. These studies will be translated back into clinical practice to improve treatment of snake bites.
To Search For Genetic Causes Of Renal Disease In The Tiwi Island Aboriginal Population

Summary
This project aims to continue work done on identifying the genetic basis to the kidney disease suffered by the Tiwi population from Bathurst and Melville Islands. It is based on the outcomes of the first genome-wide scan in an Aboriginal population. The scan yielded a genetic association to a locus that has led to a very plausible hypothesis. If this hypothesis is correct, and the goal of this project is designed to find this out, then public health measures should be able to halt the progressio ....This project aims to continue work done on identifying the genetic basis to the kidney disease suffered by the Tiwi population from Bathurst and Melville Islands.

Functional Resolution Of PTEX, The Exporter Of Virulence Factors In Malaria Parasites.

Funding Amount
$625,212.00
Summary
Almost half a million people die each year of malaria and nearly half the world’s population are at risk. To eliminate malaria this century we will need new drugs and vaccine to fight the disease. One potential drug target are the molecular gateways called PTEX, that are used by parasites to export virulence proteins into their human host cells. This grant aims to understand how the PTEX molecular machines work so we can develop new drugs to block them and kill the parasites.
