Molecular Basis For The Emergence Of Community Acquired Staphylococcus Aureus

Funding Amount
$427,518.00
Summary
Golden Staph is a major problem in our hospitals but serious Golden Staph infections are increasingly common in the community, among otherwise healthy people who have had no contact with hospitals. This project will find out how Golden Staph is evolving to become more likely to cause disease in the community. This knowledge can then be used to design new strategies for early detection, prevention and treatment.
New Therapeutic Approaches For Genetic Skeletal Disorders

Funding Amount
$961,150.00
Summary
Genetic skeletal disorders are a significant disease burden with limited therapeutic options. We will use mouse models of cartilage and bone disorders and human induced pluripotent stem cell derived bone and cartilage 'disease in a dish' models to test repurposed FDA-approved drugs and new drug candidates as novel therapeutic strategies.
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.
Comparative Pathophysiology And Clinical Epidemiology Of Knowlesi Malaria

Funding Amount
$267,172.00
Summary
The simian parasite P. knowlesi is the most common cause of malaria in Malaysia and can cause severe and fatal disease. We are currently conducting a study of all malaria patients admitted to a tertiary referral hospital in Sabah, Malaysia. This will allow us to describe the epidemiological and clinical features of the hospitalised patients, including changes over time. We are also conducting novel pathophysiological studies which will allow us to understand how P. knowlesi causes sever disease.
Functional Genomics Of Malaria Liver Infection And Transmission

Funding Amount
$470,144.00
Summary
Chemotherapy is the front line defense against malaria but resistance is emerging. The WHO has advised that new drugs should target parasite stages that perpetuate the transmission of malaria to break the cycle of infection. We have identified proteins that are essential for the two transmissive stages of the most deadly parasite to infect their hosts. We will determine the precise function of these proteins and the mechanisms they govern. This may guide the development of new interventions.
Role Of Plasmepsin V And PTEX Complex In Plasmodium Liver Infection
Funder

Funding Amount
$848,408.00
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.
Gene Discovery And Pathobiology In Muscle Diseases
Funder
National Health and Medical Research Council
Funding Amount
$425,048.00
Summary
I aim to find the genetic causes of muscle diseases that are lethal or severely debilitating. These diseases result in a significant burden to the affected individuals and their families and also on Australia’s Health care system. A genetic diagnosis provides families with answers, allows family planning, such that couples do not have another affected child, enables appropriate clinical management and gives researchers evidence as to how to develop treatments.
Helicobacter Pylori Acquisition Of Host Cholesterol: Its Role In Inflammation
Funder
National Health and Medical Research Council
Funding Amount
$417,380.00
Summary
The bacterium Helicobacter pylori is present in the stomach of half the world’s population. It is estimated that 20% of these people will suffer from peptic ulcer disease, whereas as many as 1% will develop stomach cancer later in life. The common factor in all these diseases is the inflammation induced by the bacterium. This project will investigate a new mechanism by which H. pylori causes inflammation and how dietary cholesterol may be involved in this process.
