A Transmission-Blocking Vaccine To Prevent Toxoplasmosis

Summary
Toxoplasma gondii causes a globally important zoonotic disease. It is transmitted by cats, and finds its way into our food chain via infected meat and contaminated water. We have used a unique functional genomics pipeline to discover proteins crucial for reproduction of Toxoplasma in the cat. We will now test combinations of these proteins to immunise cats and prove that we can develop a vaccine that blocks transmission of this highly significant parasitic disease.
Group A Streptococcal Human Challenge Study: Accelerating Vaccine Development

Funding Amount
$2,018,741.00
Summary
Infection with group A streptococcus (GAS) is a major cause of morbidity and mortality worldwide, including in the Aboriginal population of Australia. Concerted efforts for vaccine development have been hampered by the absence of a suitable animal model. To address this critical knowledge gap we propose to develop a controlled human infection model of GAS infection. This model will provide a direct pathway for the future appraisal of novel GAS vaccines.
The Role Of Capsid Protein Nucleolar Localisation In Chikungunya Virus: Implications For Vaccine Development
Funder

Funding Amount
$520,520.00
Summary
Chikungunya virus (CHIKV) is a globally widespread mosquito-borne alphavirus capable of causing considerable human morbidity and mortality. With no CHIKV vaccine or antiviral available this proposal aims to develop a live attenuated CHIKV vaccine, rationally designed by investigating the host cell nucleolar trafficking of CHIKV capsid protein. This vaccine has the potential to provide cross-protection against additional arthritogenic alphaviruses endemic to Australia such as Ross River virus.
Economic Evaluation Of Alternative Pneumococcal Vaccination Strategies

Funding Amount
$242,894.00
Summary
Pneumococcal vaccination is a readily available preventive strategy that can offer substantial protection to the elderly but it is important that we carefully evaluate the different potential strategies to ensure the most (cost-) effective approach to prevention is identified. This grant will explore alternative strategies to control pneumococcal-related disease in elderly Australians using the available vaccines.
Providing The Evidence To Guide Adult Immunisation Strategies

Summary
Australia's population is ageing and strategies to improve health in older adults are necessary to prevent an increasing burden on our health system. Adult vaccination is a relatively under-researched area with great potential to prevent disease in the population. This project focuses on four common vaccine preventable disease in adults, herpes zoster (shingles), influenza, invasive pneumococcal disease and pertussis. It will identify what their impact is on the health system and what groups of ....Australia's population is ageing and strategies to improve health in older adults are necessary to prevent an increasing burden on our health system.

Community-wide Active Case Finding For Tuberculosis

Funding Amount
$3,422,325.00
Summary
During 2010, 8.8 million people developed TB and 1.45 million people died due to the disease. In this project, which will be conducted in Vietnam, one of the countries in our region with a particularly high prevalence of TB, we will test a new form of an old intervention: community-wide screening for TB, not with x-rays but by testing sputum. If the project is successful it has the potential to lead to a giant leap forward towards the elimination of TB as a global health problem.
Defining The Molecular Effectors Of Gene/environment Interaction On Mouse Heart Development

Funding Amount
$749,271.00
Summary
One third of all birth defects involve the heart, and are the most common cause of infant death. Some defects are due to genetic factors, but others arise when the pregnant mother is exposed to environmental stress. We will examine how one stress (low oxygen levels) causes abnormal heart formation in the embryo, look at what causes this at a molecular level, and explore if such stress increases the risk of heart defects in families with a history of such abnormalities
How Does Paternal Obesity Influence Offspring Glucose Tolerance?
Funder

Funding Amount
$503,398.00
Summary
Obesity and diabetes are closely related to these conditions in either parent, but how the father contributes is unclear. We have shown that normal females mated with obese fathers consuming high fat diet, produce offspring who develop glucose intolerance and impaired insulin secretion. This work will examine the mechanisms underlying this effect in the rat, testing a novel role for environmental factors in the father on disease in offspring that may be relevant to the growing obesity epidemic.
Understanding Sphingolipid Mediators Of Insulin Resistance

Funding Amount

Summary
Sphingolipids are a class of lipid metabolites that have a variety of functions within cells. It has been known for some time that an accumulation of excess lipid, including certain sphingolipids, can adversely impact insulin action and glucose metabolism in cells. In this project we will a combination of strategies to test the hypothesis that the sphingolipid profile can be manipulated to have favourable effects on metabolism.
Developmental Schizotypy In The General Population: Early Risk Factors And Predictive Utility.
Funder
National Health and Medical Research Council
Funding Amount
$830,952.00
Summary
This study will determine early childhood risk factors for psychosis-proneness in children aged 11 years, and emerging signs and symptoms of mental health disorders of these children, using population data from the NSW Child Development Study. Determining risk for psychosis as early as possible in the life course will enable the provision of preventative interventions to children at critical points in development.
