Targeting Antimicrobial Resistance And Host Immune Evasion In Staphylococcus Aureus
Funder
National Health and Medical Research Council
Funding Amount
$892,831.00
Summary
This project aims to show how one of the most important human superbugs, Staphylococcus aureus (Golden staph), develops resistance to one of our most important last-line antibiotics and the immune system to cause life-threatening infections. Our work will also investigate and test new treatment strategies for this common and challenging human pathogen.
Investigating The Role Of Mitochondrial Tom40 In Regulated Cell Death And Neurodegeneration.

Funding Amount
$972,660.00
Summary
Mitochondria are internal compartments of cells, separated by bounding membranes. They are crucial to the life and death of cells, and to quality of human life and ageing. Diseases of the nervous system can be caused when mitochondria do not function properly. Our aim is to discover why a protein complex called TOM embedded in the bounding membrane is linked to dementia in some people. This will also lead to a better general understanding of the connection between mitochondria and human health.
Identifying How The Enteric Nervous System Regulates Gut Permeability In Autism

Funding Amount
$448,643.00
Summary
This project aims to investigate causes of increased gut permeability in neurological disorders including autism and will apply neuroscience, immunological and microbiology techniques to clarify the causes of increased gut permeability in a well-characterised genetic mouse model of autism.
Understanding The Role Of Lipid In Membrane Permeabilization By The Bcl-2 Family Executioner Proteins

Funding Amount
$626,524.00
Summary
Apoptosis is a form of programmed cell death that protects our bodies from dangerous cells, e.g cells infected with viruses or that might become cancerous. A network of protein families control this process and this work will understand how certain members regulate a crucial step in this cell death pathway. Our studies will reveal key insights into apoptosis at the molecular level and inform the development of therapeutics for diseases characterised by dysregulated cell death such as cancer.
Bivalent Analgesics: Rational Design Of Selective Ion Channel Inhibitors With Optimised Mechanism Of Action
Funder
National Health and Medical Research Council
Funding Amount
$904,890.00
Summary
The so-called 'opioid crisis' leading to the death of millions of people worldwide has highlighted the urgent need for development of novel safe and efficacious pain killers without addictive potential. This proposal aims to rationally design novel analgesic compounds by linking different classes of ion channel modulators with desirable properties.
Probing Changes In G Protein-coupled Receptor Signalling Networks During Breast Cancer Progression

Funding Amount
$892,733.00
Summary
The b2-adrenoceptor is a protein receptor that enables cells to respond to hormones. In breast cancer, this receptor causes more aggressive tumour cells to metastasise faster in response to stress. This proposal aims to understand why this response occurs in only very aggressive cells, and to identify how we can better target blocking drugs to this receptor. This could allow us to design better drugs with fewer side effects.
Genetic testing of IVF embryos promises to improve success but shows no effect of live-birth rates. Many embryos are mosaic: containing cells with correct and incorrect chromosome numbers. Current testing is an invasive biopsy which fails to diagnose how many cells are abnormal in the cells that develop into the baby. Here we will use imaging to determine the ratio of abnormal:normal cells resulting in a non-invasive diagnostic that will improve IVF success.
An Integrative Approach To Define And Attenuate Genomic Risk Of Coronary Artery Disease

Funding Amount
$988,454.00
Summary
One in four individuals that have a heart attack do not have traditional risk factors such as high blood cholesterol levels. This highlights the importance of 'family history', which we can now quantify as 'genetic risk'. These studies will determine (i) which genes are important in contributing to this genetic risk (ii) how these genes change biological pathways to increase risk and (iii) the effectiveness of modulating these biological pathways to reduce the risk of heart disease.
Harnessing Macrophage-derived Cytokine Signalling In Skeletal Muscle Regeneration
Funder
National Health and Medical Research Council
Funding Amount
$991,926.00
Summary
We propose to develop novel therapies and tissue engineering approaches for the treatment of muscle injury and wasting disorders using specific muscle stem cells called satellite cells. Our ultimate aim is to accelerate the development of safe, effective and affordable muscle stem cell-based therapies, in an attempt to lessen the disease burden of muscle wasting disorders. The approach will make use of the novel stem cell activating compounds and immune cells that we have identified.
Growth Factor Directed Developmental And Pathological Lymphangiogenesis
Funder
National Health and Medical Research Council
Funding Amount
$1,048,507.00
Summary
The formation of new lymphatic vessels occurs in normal development and in diseased tissues in cancer and cardiovascular disease. We have developed an understanding of how lymphatics form in development but we understand far less about how they form in disease. This project will apply multidisciplinary approaches, including genetics and computational biology, to compare how lymphatics form in development and disease. We hope to uncover new ways to manipulate this process for therapeutic gain.
