Summary
Australia has one of the world's most rapidly ageing populations. It is estimated that in 30 years time over 30% of the population will be over 65; many will suffer from a debilitating, age-related disease. The diseases of ageing represent one of the major health challenges this century. Despite their increasing incidence, our understanding of the underlying causes is limited. A common feature is the accumulation of damaged proteins in cells and tissues. Damaged proteins are usually broken down ....Australia has one of the world's most rapidly ageing populations. It is estimated that in 30 years time over 30% of the population will be over 65; many will suffer from a debilitating, age-related disease. The diseases of ageing represent one of the major health challenges this century. Despite their increasing incidence, our understanding of the underlying causes is limited. A common feature is the accumulation of damaged proteins in cells and tissues. Damaged proteins are usually broken down by the cells and replaced, but in many age-related diseases this process fails. The most common source of protein damage is attack by oxygen-derived free radicals. These are by-products of our body's need for oxygen and can originate from atmospheric pollutants. Oxygen rusts metal, makes fat go rancid and can cause irreparable damage to proteins and other biological molecules. Free radical damage contributes to the development of many age-related diseases such as atherosclerosis and neurodegenerative diseases such as Alzheimer's disease. The accumulation of damaged proteins can cause cell death. Our knowledge of the mechanisms by which cells remove proteins damaged by oxygen and the reasons for their accumulation is limited. In this project we will use a novel technique we have developed to generate oxidised proteins in ageing cells. We will identify cellular mechanisms required for the efficient removal of damaged proteins and those mechanisms which fail in ageing cells. We will focus on a group of proteins which protect damaged proteins from aggregating and accumulating and we will examine how we can prevent the accumulation of oxidised proteins by stimulating the body s defence mechanisms. Since the population of Australia is ageing, diseases of ageing are going to consume an increasing amount of the national health budget. A better knowledge of these cellular mechanisms will allow us to design effective prevention and treatment strategies which are at present lacking.Read moreRead less
Economic, social and cross cultural issues in non-pharmaceutical protection of front line responders to pandemic influenza and emerging infections. The protection of front line responders in a pandemic is essential to underpin an effective response. This research is the only work internationally which will address a key gap in evidence. This research has major implications for the national stockpile and for management of front line responders in a pandemic.

The protection of front line responders in a pandemic is essential to underpin an effective response. This research is the only work internationally which will address a key gap in evidence. This research has major implications for the national stockpile and for management of front line responders in a pandemic. These data are urgently needed, not just in Australia, but globally to inform pandemic planning and disease control policy around emerging infections and bioterrorism.Read moreRead less
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.

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. 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 adults would benefit most from vaccination.Read moreRead less
The control of epidemics requires cross-sectoral engagement across various fields such as health, government, international law and security, at both national and international levels. The changing global landscape poses an increased threat to biosecurity, calling for cross-sectoral collaborative research and engagement. Integrated Systems for Epidemic Response (ISER) will convene and lead multidisciplinary systems research in epidemic response.
Prevention Of Beta Cell Destruction In Type 1 Diabetes By Immunotherapy Using Parasite-derived Molecules.

Funding Amount
$518,443.00
Summary
To prevent type 1 diabetes, compounds that avert the autoimmune destruction of beta cells are needed. We are exploiting the potential of ñworm therapyî by mimicking the beneficial immune effects of parasite worm infection. We have identified the molecules that the parasite uses to influence host immune responses. We have demonstrated that these novel immune-modulatory worm molecules prevent diabetes in a mouse model. This offers great potential for the development of therapeutic interventions.

The biosynthesis of structural proteins in parasites. The socio-economic impact of parasitic diseases, in Australia and throughout the world, is enormous- they kill 2-3 million people per year and cost livestock industries billions of dollars per annum. Some are serious food and waterborne threats, such as the coccidia, because they are transmitted from person-to-person via the faecal-oral route, or via ingestion of contaminated water or food, or through the ingestion of cysts in raw or underco ....The biosynthesis of structural proteins in parasites. The socio-economic impact of parasitic diseases, in Australia and throughout the world, is enormous- they kill 2-3 million people per year and cost livestock industries billions of dollars per annum. Some are serious food and waterborne threats, such as the coccidia, because they are transmitted from person-to-person via the faecal-oral route, or via ingestion of contaminated water or food, or through the ingestion of cysts in raw or undercooked meat. They cause diarrhoea, which in some cases, can be life-threatening. We will understand how the coccidia protect themselves as they move from host to host and, through that understanding, develop new ways to control them and eliminate the suffering caused by parasitic diseases.Read moreRead less
