Unravelling The Mechanism Coupling Synaptic Activity With Neurotrophin Signaling In The Nervous System
Funder

Funding Amount
$640,815.00
Summary
Although active brain cells are known to survive for much longer than inactive ones, the mechanism underpinning this essential process has remained elusive. We have uncovered a direct coupling between neuronal activity and survival signals. The purpose of this grant application is to establish the molecular mechanism underpinning this coupling and understand how neuropathic pathogens manage to harness it with devastating effects to the brain.
Circuit Breaker: Investigating The Regulatory Circuits Controlling Expression Of Drug Efflux Pumps In The Nosocomial Pathogen Acinetobacter Baumannii
Funder

Funding Amount
$515,244.00
Summary
Hospital-acquired infections caused by drug resistant pathogenic bacteria cost billions of dollars and increase patient pain and morbidity. This research will study the genes controlling multidrug efflux pumps in a major hospital-acquired bacterial pathogen, Acinetobacter baumannii. These efflux pumps make the bacteria resistant to antimicrobials by pumping them out of the cell. The results will allow us to better track drug resistant strains and will inform treatment options.
Enhanced Methods Of Communicating Correct Use Of Child Car Restraints: A Controlled Trial

Summary
Working with our associate investigators from the Australian and European child restraint industry, we will conduct a controlled trial of enhanced methods of communicating correct use of child car restraints with product information supplied at the point of sale.
Physiological Function Of Nedd4-2 In Regulating The Epithelial Sodium Channel And Cystic Fibrosis Transmembrane Conductance Regulator

Funding Amount
$949,572.00
Summary
Optimal transport of sodium and chloride ions is essential for the maintenance of electrolyte balance, blood volume, blood pressure and lung function. We are studying the control of a key sodium channel (the epithelial sodium channel) and a key chloride channel (cystic fibrosis transmembrane conductance regulator) by an enzyme called Nedd4-2. This project will enable us to understand how Nedd4-2 regulates these two ion channels and to study the pathological consequences of the loss of Nedd4-2.
Work-related Road Traffic Injury: Managing The Risk

Summary
Almost one third of registered motor vehicles in Australia are used for work purposes, the implications of this research namely, estimating the magnitude and identifying organisational determinants associated with work-related road traffic injury are substantial. Interventions arising from the findings of this research will contribute significantly to reductions in work-related road traffic injury and will support the National Road Safety Strategy target of a 30% reduction in serious injuries by ....Almost one third of registered motor vehicles in Australia are used for work purposes, the implications of this research namely, estimating the magnitude and identifying organisational determinants associated with work-related road traffic injury are substantial. Interventions arising from the findings of this research will contribute significantly to reductions in work-related road traffic injury and will support the National Road Safety Strategy target of a 30% reduction in serious injuries by 2030.Read moreRead less
Interactions Between H5N1 And The Respiratory Epithelium

Funding Amount
$623,065.00
Summary
This project examines the hypothesis that the severity of H5N1 infection is due to activation of signalling pathways in the lung not activated by human influenza and leads to fluid accumulation in the lungs death of respiratory cells. This study will improve our understanding of influenza infection and identify targets for treatment of H5N1.
Neuronal communication relies on the process of exocytosis by which neurons release a neurotransmitter. Exocytosis is critical for the simplest muscle movement to complex tasks such as learning and memory, and is altered in several neurodegenerative pathologies. We will investigate how the protein Munc18 controls exocytosis. This research will be important for understanding how neurons communicate in health and disease and will be relevant to other processes such as insulin release in diabetes.
Copper Pathways Are Altered In Parkinson’s Disease: Implications For Cell Vulnerability
Funder
National Health and Medical Research Council
Funding Amount
$341,398.00
Summary
The cause of brain cell death in Parkinson’s disease is unknown but we have shown that copper levels are reduced in the vulnerable brain regions in this disorder. As copper is vital for the normal function of key brain proteins we suggest that reduced copper contributes to cell damage in vulnerable brain regions. This project investigates why brain copper levels are reduced in the Parkinson’s disease brain and the consequences of this change for brain cell function and survival.
Role Of Non-transferrin Bound Iron In Iron Overload Disease

Funding Amount
$669,504.00
Summary
Plasma non-transferrin bound iron (NTBI) levels are elevated in iron overload disorders. Excess NTBI has serious health consequences as it is toxic and may induce cellular dysfunction and injury. We will investigate the molecular mechanisms by which NTBI transport is regulated, the contribution of NTBI to the development of iron overload and its impact on oxidative-mediated liver and heart injury in iron overload conditions associated with Hereditary Haemochromatosis and thalassaemia.
Mechanisms Of Regulating Gene Expression Via Selective MRNA Transport
Funder
National Health and Medical Research Council
Funding Amount
$424,076.00
Summary
A critical step in the gene expression pathway that is altered in cancer is nuclear export of mRNA. We have demonstrated that mRNA export is not constitutive, but highly selective and can regulate distinct biological processes through poorly understood mechanisms. This project aims to dissect the molecular mechanisms of regulating gene expression via selective mRNA transport. This will establish selective mRNA export as a novel area of research in cancer biology.
