Summary
Respiratory infections are a leading cause of death and illness throughout the world. We have discovered a 'friendly' bacteria that can be applied up the nose to prevent ear infections and the 'flu in mice. We will now test this novel therapy in humans to check it is safe and that it stimulates the human immune system in the same way that it does in mice. This will provide essential information to conduct clinical trials, with the aim to produce a medicine that prevents respiratory infections.
Influenza A Viral Infection And Pregnancy Complications

Summary
Pregnant women who contract influenza are 5 times more likely to be hospitalised than the general population. Babies of mothers with influenza are also associated with increased perinatal mortality rates. We hypothesise that influenza infection in pregnancy significantly impairs the maternal vascular system resulting in maternal and foetal morbidity. Outcomes from this research may change current treatment modalities to improve maternal and foetal outcomes complicated by influenza infection.
Oleoyl-ACP-hydrolase As An Early Predictive Biomarker For Severe And Fatal Influenza

Summary
Millions are hospitalized with severe influenza disease and ~500K die annually but the underlying mechanisms that drive disease are still not fully understood. We have identified a key role for an enzyme involved in fatty acid metabolism, which is profoundly elevated in patients who succumb to influenza and is thus a predictor for fatal outcomes. This research aims to investigate how this enzyme affects infection and impairs immune responses to drive severe respiratory viral disease.
Silencing Pulmonary Nociceptors To Treat Severe Respiratory Viral Infections

Summary
The lungs receive a rich supply of nerve fibres, many of which play an important role in helping defend against pathogens, including viruses. When viral infections become severe, too much inflammation occurs in the lungs and this creates a serious and difficult to treat clinical problem. Hundreds of thousands of people each year die from the complications of severe lung infections. We are investigating a potential new therapy that targets the lung nerves and relieves excessive inflammation.
Perinatal Microbe-host Interactions Regulate Neonatal Dendritic Cell Development

Summary
Acute lower respiratory tract infections (ALRI) are the leading cause of childhood mortality globally, and increase the risk of chronic lung diseases in later-life. Diverse communities of microorganisms - the microbiome - assemble in infancy and support immune development. In this study, we will explore the relationship between the microbiome and its metabolites, and the expression of an important hormone that regulates the development of the immune system to confer protection against ALRI.
Targeting Neurovascular Communication As A Novel Way Of Reducing Vision Loss In Diabetes

Summary
Diabetes is a leading cause of blindness. Here, we evaluate whether diabetes causes changes in the way neurons signal to blood vessels, and whether blocking some of the signals from neurons reduces blood vessel abormalities. Overall, this information is critical to our understanding of the early changes that occur during diabetes and whether novel treatments used early in diabetes can prevent long term changes and vision loss.
Dissecting Brain Network Ageing Using Whole Brain Imaging

Funding Amount
$692,964.00
Summary
In this proposal, we will make the first attempt to map the whole brain activity change during ageing using a series of state-of-the-art techniques. We will also identify genetic and pharmacological interventions that improve brain network function during ageing. Outcomes from this research will provide an unprecedented understanding of functional ageing within the brain and identify therapeutic interventions to prevent this process.
Organisation Of The Genome During The Development Of Antibody-secreting Cells

Funding Amount
$886,155.00
Summary
Each cell of our body contains over two metres of DNA that must be correctly packaged in order for our cells to function. We are using cutting-edge molecular biology techniques to study how this DNA circuitry is established in the white blood cells of our immune system that produce antibodies. Our novel approaches will reveal unique strategies to modulate immune responses to our benefit.
A Novel Interaction Between The Immune And Vascular Systems In Early-onset Preeclampsia; An Opportunity For New Treatments?

Summary
Preeclampsia is a pregnancy complication that leads to poor birth outcomes and elevated lifelong cardiovascular disease risk in 4 million women each year. It has no cure and treatments are limited because the causal mechanisms are not understood. We have identified a specialised immune cell in the mother's blood that assists blood vessels to function properly in pregnancy. We will assess whether interventions to enhance these cells can improve poor blood vessel function and pregnancy outcomes.
About one in eight known genetic disorders involve DNA alteration that activates a cellular quality control mechanism that disables the affected gene. This mechanism is more efficient in some individuals than others. It can influence disease outcomes and severity. We will engineer and apply tools and models to measure and manipulate this crucial cellular mechanism. This will allow us to predict disease severity as well as to intervene where a manipulation of this mechanism will be beneficial.
