Funding Amount
$569,620.00
Summary
In this study we will characterise the manner in which genes essential for the virulence of Porphyromonas gingivalis, a bacterium associated with chronic periodontitis, are regulated. This will provide information on how this bacterium causes disease and may offer opportunities for the development of new treatment strategies.

Summary
We have developed a Lipid-Core-Peptide vaccine adjuvant system, based on the incorporation of lipoamino acids into poly-functional moiety that provides an excellent means for enhancing the antigenicity of a potential peptide-vaccine. As the system contains many variables, which allow substantial modifications to be made, we now wish to fully optimise its structural configuration. A library of spacer-lipoamino acid-poly-functional multiplier systems will be synthesised on solid phase.

As the system contains many variables, which allow substantial modifications to be made, we now wish to fully optimise its structural configuration. A library of spacer-lipoamino acid-poly-functional multiplier systems will be synthesised on solid phase. Model peptide epitopes will be synthesised on these different lipid-core systems and the antibody response will be compared with the response of the model peptide epitopes coupled to conventional vaccine carriers. The Lipid-Core Immunogen constructs including particulate systems will be administered orally as well, followed by measurement of the serum IgG response and the secretory IgA. This novel system can be used for any potential vaccine-peptide epitope and can open a new route to modern vaccination. The specific advantages of these kind of synthetic vaccines include the greater stability of the vaccine, reproducibility, eliminate the use of toxic conventional adjuvants. The key to this system is a novel carrier construct, which is non-toxic and not immunogenic. The system confers immunity with smaller risk of reaction, since it generates antibody production only against the infective microorganism. Vaccination via the oral route is highly desirable since it can overcome many of the disadvantages inherent in administration by injection - e.g. poor patient acceptability, requirement for skilled medical personnel, risk of HIV and other blood-borne diseases, restricted availability and, in cases, stimulation of the wrong type of immunity. Development of vaccines for oral administration will make them much more widely available, permitting self-administration by patients and markedly improving the operation of Public Health vaccination programs, particularly in developing countries.Read moreRead less
Obesity, Overweight And Hospitalisation: Identifying Targets For Interventions To Prevent Adverse Health Outcomes

Summary
Obesity is an important and rapidly increasing health problem, especially in indigenous communities. The proposed project investigates how obesity affects the risk of hospital admission in Indigenous and non-Indigenous Australians, including providing evidence regarding the nature of the hospitalisation, the cost and whether specific groups are at a higher risk of obesity-related hospitalisation. In doing so it aims to identify targets for intervention to reduce obesity-related hospitalisation
Identification And Characterization Of A Novel Tumor Suppressor

Summary
Australia has the highest rate of skin cancer in the world, with over 380,000 people diagnosed every year. Of these, over 370,000 have non-melanoma skin cancers including squamous cell carcinoma and basal cell carcinoma. Our laboratory has identified a gene in mice that protects animals from squamous cell cancer. The studies proposed in this grant examine the mechanisms underpinning this protective role and may have important implications for the prevention of skin cancers in humans.
Health, Wellbeing, Disability And Service Pathways In Older (80+) Australians

Funding Amount

Summary
Over the next 40 years there will be a rapid increase in the numbers of people aged 80 year and over. In this study we will examine the health status and service use needs and patterns of a sample of older Australian who form part of an existing 12 year longitudinal study on ageing and who are now moving intoold-old age. The study will provide inmportant insights for service planners and older people themselves about the health and community service needs for people in the study age group.
Airway Wall Thickness And Heterogeneity Are Key Determinants Of Asthmatic Airway Function.

Summary
Asthma is a common disease which is typified by excessive narrowing of the airways in response to stimuli that are trivial to non-asthmatic individuals. However, little is known about what causes asthmatic airways to be able to narrow so excessively. In this study, we will be looking at the importance of thickening of the airway walls in relation to excessive airway narrowing in asthmatics.

However, little is known about what causes asthmatic airways to be able to narrow so excessively. In this study, we will be looking at the importance of thickening of the airway walls in relation to excessive airway narrowing in asthmatics. We will also look to see how patchy the airway narrowing is in asthmatics and how this relates to excessive airway narrowing that occurs in severe asthmatic attacks. We will therefore be studying asthmatics of varying degrees of disease severity as well as those admitted to hospital because of acute severe attacks of asthma, and comparing them with a group of non-asthmatic subjects.Read moreRead less
Effects Of Latrepirdine On Beta Amyloid Clearance, Aggregation And Neurodegeneration In Alzheimer�s Disease

Summary
Alzheimer's disease (AD) is becoming more common with our growing aged population and currently no treatment exists that halts disease progress. The increasing health costs of AD underscore the need for development of any treatment that will slow or halt AD pathogenesis. By understanding the mechanisms of action of a drug [latrepirdine] that has recently shown some promise in phase II clinical trials, related drugs that are more specific and potent will be developed.
A Comprehensive Immunoproteomic Analysis Of The Repertoire And Dynamics Of Human Antibody Responses To Malaria

Funding Amount

Summary
Malaria infects 10% of humanity and kills more than two million children annually. We have developed a powerful new approach to comprehensively profile antibody responses against the malaria parasite in PNG children during the critical period of development of disease immunity. The proposed work will help us to better understand the targets and mechanisms of naturally acquired immunity and prioritise the development of future thereapeutic vaccines, drugs or diagnostics.
