A DENDRITIC SUBSTRATE FOR THE CHOLINERGIC CONTROL OF NEOCORTICAL OUTPUT

Funding Amount
$898,340.00
Summary
The forebrain cholinergic system controls neocortical activity and cognitive function. This project will investigate the mechanisms by which the cholinergic system controls neocortical circuit activity in rodent models using advanced optical and electrical recording methods. The results will provide a foundation for the understanding of how dysfunction of the cholinergic system results in cognitive decline in humans, and identify new targets for improved treatment of human cognitive impairment.
Multi-centre, Multi-disciplinary Study Using A Systems Biology Approach To Investigate Immunomodulation In Children With Acute Wheeze

Summary
The concept that immunomodulation using naturally-occurring bacterial agents can treat asthma has reached international prominence. This is backed by strong epidemiologic and clinical trial data. However, detailed knowledge of the immunological mechanisms involved is essential to allow more focused therapeutic agents to be developed. The proposed multi-disciplinary immunomodulation study in 200 children aims to provide this essential information using an advanced systems biology approach.
The Differential Contribution Of Programmed Death-1 Ligands To Malarial Immunity

Funding Amount
$327,784.00
Summary
This research aims to understand how the Malaria parasite, which causes one of the world’s deadliest diseases, evades immunity. It will provide a significant advance in our knowledge of immunity against malaria and impact on current strategies to develop an efficacious vaccine or treatment for malaria.
NOD1 Sensing Of H. Pylori Peptidoglycan Promotes Cell Survival And Bacterial Persistence

Summary
The bacterium H. pylori lives in the stomach of half the world’s population and is a major cause of human disease, including peptic ulcers and stomach cancer. This project will investigate how H. pylori is able to manipulate the host immune system by modifying the composition of its outside layer (the cell wall). In so doing, H. pylori causes changes in cells of the stomach lining that allow the bacterium to persist, but that also may predispose the host to cancer.
Molecular Basis For The Efficient Processing Of Antigens Taken Up By Clec9A, A DAMP Receptor On Dendritic Cells

Funding Amount
$1,302,392.00
Summary
Dendritic cells (DC) of the immune system utilise specific receptors to sense danger signals from their environment. We identified a DC danger receptor, Clec9A, which recognizes and induces immunity to “dangerous” dead cells eg. infected cells or killed tumour cells. We will investigate how DC use Clec9A to process “dangerous” dead cells, and the factors that control the potency of this immune response. This will enable us to develop novel immunotherapies for infectious diseases and cancer.
The Role Of Cytokines In Tumor-induced Immunosuppression

Summary
Cancer-induced immune suppression is a major obstacle to the effective treatment of many cancers. We have shown that the cytokine IL-23, plays an important role in cancer initiation, growth and development. My project aims to characterize the cells that produce IL-23 in the cancer microenvironment and define how it suppresses cells of the immune system. A greater understanding of this cytokine’s mechanism of action will enable the rational improvement of treatments for patients with cancer
Toxoplasma Gondii Infection Of Human Retinal Pigment Epithelium

Summary
Ocular toxoplasmosis is a vision-threatening parasitic eye infection that is common in Australia and worldwide. No treatment cures the disease. This work will characterize cellular and molecular events occuring in the eye during an infection, which is an important first step toward the development of more effective treatments for patients with the condition.
Depression is the most prevalent health problem in young people, with a prevalence as high as 24 percent. There is evidence demonstrating a link between depression and chronic inflammation and oxidative stress, suggesting that drugs which modulate those factors may have antidepressant properties. This study is designed to establish whether the use of (i) rosuvastatin or (ii) aspirin, two drugs that modulate both the inflammatory and oxidative systems, reduce symptoms of depression in young peopl ....Depression is the most prevalent health problem in young people, with a prevalence as high as 24 percent. There is evidence demonstrating a link between depression and chronic inflammation and oxidative stress, suggesting that drugs which modulate those factors may have antidepressant properties. This study is designed to establish whether the use of (i) rosuvastatin or (ii) aspirin, two drugs that modulate both the inflammatory and oxidative systems, reduce symptoms of depression in young people with major depression.Read moreRead less
Molecular Characterisation Of The Dendritic Cell Receptor Clec9a And Its Ligand Interactions
Funder

Funding Amount
$651,784.00
Summary
The immune system senses danger from infectious diseases, damaged and dead cells. We identified a danger receptor, Clec9A, on a specialised cell type of the immune system in mice and humans. Clec9A recognizes and induces immunity to dangerous dead cells. Delivering vaccines to Clec9A improves vaccine responses. We will investigate how Clec9A recognises and reacts to danger, and how we can mimic this recognition to improve vaccine design.
Host-pathogen Interactions In Clostridial Myonecrosis

Funding Amount
$577,573.00
Summary
We will analyse the interaction between the bacteria that cause gas gangrene, and the infected host, from both a host and pathogen perspective. We will examine how the host’s response to infection can be modulated to decrease the severity of disease and we will identify the biochemical processes that are essential for bacterial growth in the host, a necessary prerequisite for disease. Outcomes will be a better understanding of the mechanisms of disease causation and improved disease control.
