Summary
As liver cancer risk correlates with increased liver stem/progenitor cell numbers, therapies that reduce their numbers will reduce cancer development. On the contrary, therapies to increase progenitor cell numbers will assist their use in cell therapy-based approaches or artificial liver devices to treat chronic liver disease. This project will determine how to use inflammatory cells to manipulate progenitor cell numbers.
Improving Treatment Strategies For Chronic Alphaviral Arthritic Diseases

Summary
Chikungunya virus and Ross River virus cause epidemics of acute and chronic arthritic disease in humans, which is often poorly managed with current treatments. This grant seeks to understand the mechanisms that give rise to disease in order to identify improved treatment strategies. Both the persistence of viral replication in joint tissues and unnecessary inflammatory responses appear to be important factors driving chronic disease.
Developmental-associated Dysregulation Of Innate Anti-microbial Immunity In Early Life As A Determinant Of Susceptibility To Atopic Asthma

$570,334.00
Summary
Previous NHMRC-sponsored research from the applicants has demonstrated that one of the strongest risk factors for subsequent development of asthma is having chest infections during infancy that are so severe that they trigger symptoms of fever and wheeze. It is not known what predisposes susceptible infants to these severe infections, and this project will attempt to define the mechanisms of susceptibility.
Mechanisms Underlying Growth, Lineage Commitment And Differentiation Of Liver Progenitor Cells

Summary
Liver disease is a serious health problem. Viral hepatitis, obesity and alcohol can result in end-stage liver disease. Organ transplant is the only treatment available. A widening gap between organ donations and recipients mandates alternative treatments are developed. Cell transplantation and artificial liver devices are alternatives which can use liver progenitor cells. We will investigate how factors grow and convert them into liver cells for treating liver disease patients.
Postviral Wheezing In Childhood: Disregulation Of Airway Tone?

Summary
Asthma is a very common childhood condition that is becoming increasingly more common. Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens. Ho ....Asthma is a very common childhood condition that is becoming increasingly more common. Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens. However, many infants who wheeze with viral infections, especially in the first year of life, do not develop allergies in later life, raising the possibility that they did not have the same type of asthma as those whose symptoms persist. This project will study the effects of viral infections on lung function to determine whether particular types of virus can have detrimental effects of lung function lasting for years. We will also examine whether the age at which the infection occurs and the severity of the infection influence the long-term outcome. The project involves studying infants during the recovery phase of respiratory viral infections, older children years after documented infections and experimental animal models that have been infected under controlled conditions. By determining whether respiratory viral infections can have long-term effects on lung function that can mimic asthma, we will advance our understanding of how asthma develops. In addition, specific treatment and preventative strategies could then be developed to prevent these long-term abnormalities, instead of relying on asthma medication (especially inhaled corticosteroids) as is the current practice. Preventative strategies could include encouraging the development of specific vaccines.Read moreRead less
A Randomised Controlled Trial Of Alternative Treatments To Intramuscular Penicillin For Impetigo In Aboriginal Children

Funding Amount
$1,326,182.00
Summary
We will conduct clinical trials to find an effective, simple and cheap oral alternative to injected penicillin for skin sores which could become the universal standard of care whether the patient is in Melbourne or Milingimbi. It would also likely be adopted by the World Health Organization as a standard of care for developing countries. This would lead directly to a reduced burden of skin sores and their complications. It would also open the way for studies to explore even simpler regimens.
AusDiab 3: Emerging Risk Factors For And Long-term Incidence Of Cardio-metabolic Diseases
Funder
National Health and Medical Research Council
Funding Amount
$2,616,397.00
Summary
This study will track 11,000 Australian adults over 12 years to determine how many develop diabetes, obesity, kidney and heart disease. The study will develop ways to best predict those who are going to develop these conditions before they have arisen, and will explore a range of novel risk factors to better understand these conditions.
The Role Of Capsid Protein Nucleolar Localisation In Chikungunya Virus: Implications For Vaccine Development

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.
A Genome-wide Search For Genes Underlying The Developmental Origins Of Health And Disease

Funding Amount

Summary
Epidemic rises in the incidence of many chronic diseases such as obesity, type 2 diabetes, hypertension, coronary artery disease and mental illness have occurred in Australia over the last two decades. Antenatal, early life and childhood factors have been consistently associated with the development of such diseases. We propose to conduct a genome-wide scan in an exceptional longitudinal birth cohort in order to identify the genetic mechanisms linking early life event and adult disease.
