Summary
Muscle injury in the elderly often takes longer to heal than in younger people, however the cells responsible for this delayed healing are not well understood. Key inflammatory cells required for muscle repair in young hosts are macrophages. However, during aging we have shown that macrophage function is altered, but the mechanism is unknown. This project aims to determine the mechanisms behind age-related changes to macrophages and whether they can be targeted to improve elderly muscle repair.
Increased Airway Smooth Muscle Mass As An Independent Determinant Of Asthma Pathogenesis And Severity

Summary
Asthma is a major health burden to the community. The most common form of the disease is allergic asthma and it is thought that allergic inflammation drives associated airway abnormalities including increased airway smooth muscle (ASM) mass. This study tests a new hypothesis that airway abnormalities and allergy have separate origins but combine to produce allergic asthma, and it’s the individuals with the greatest amount of ASM who develop clinically severe asthma.
Exercise As Medicine For Heart Failure: A Novel Intervention To Improve Outcomes

Summary
Heart failure (HF) is a common, debilitating and expensive disease; prognosis remains poorer than for the most cancers. 30,000 Australians are diagnosed every year and 300,000 live with the HF, at an annual cost of ~$1Billion. Exercise training is effective therapy in HF, because it reverses many of the problems that contribute to the reduced lifespan and impaired quality of life of patients with HF. We will test an exciting new type of exercise that promising greater benefit, at lower risk.
Characterisation Of Eurl, A Novel Gene Implicated In The Etiology Of Abnormal Brain Development And Intellectual Disability

$597,541.00
Summary
Intellectual disability affects around one per cent of Australians, and can arise from genetic abnormalities during fetal life, such as through abnormal regulation of gene expression. We have identified a novel gene, known as eurl, which controls brain assembly as well as the ability of neurons to form functional connections within the brain. We will investigate how this novel gene controls brain development, and characterise eurl as a potential therapeutic target for learning and memory.
Regulation Of Neural Progenitor Cell Self-renewal By The RNA-binding Protein ZFP36L1 During Development And Disease

Summary
The timely differentiation of neural stem cells is critical during development, and the unrestrained proliferation of neural stem cells in the adult can lead to deadly brain cancers such as glioma. At present our understanding of the key molecules that regulate neural stem cell behaviour during these processes remains limited. In this proposal we will investigate the molecular determinants underpinning neural stem cell biology, both within the developing brain, and within glioma.
Group A Streptococcal Human Challenge Study: Accelerating Vaccine Development

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.
Understanding The Causes Of Childhood Congenital Anomalies Of The Kidney And Urinary Tract

Summary
Congenital anomalies of the kidney and urinary tract (CAKUT) is a common cause of renal failure in children. The majority of patients with CAKUT do not know the underlying cause of their renal anomalies. In this proposal we will characterise the developmental events that are perturbed in three mouse models of CAKUT and identify the causal gene responsible in each mouse model. We will translate this information to the clinic by screening patients with CAKUT for mutations in these newly identified ....Congenital anomalies of the kidney and urinary tract (CAKUT) is a common cause of renal failure in children.

Summary
Infants with asymmetric brain lesions are at high risk of congenital hemiplegia. This study compares modified CIMT to an equal dose of bimanual training in 150 infants recruited at 3-6 months. Both therapies will be parent-delivered supported by experienced clinicians. Outcomes include use of the impaired hand in bimanual tasks, cognitive and motor development at 12 and 24 months c.a. with measures of neural structure and functional connectivity at 24 months.
