Intergenerational Impacts Of Paternal Immune Activation On Brain Function And Dysfunction

Funding Amount
$997,690.00
Summary
We recently discovered that infection of male mice with a parasite (Toxoplasma gondii) before conception can change the epigenetic information in the sperm and alter behaviour of the offspring. This is the first evidence that pathogenic infection in males can affect the next generation. We will investigate how infection with other major pathogens, including bacteria and the virus causing COVID-19, may affect sperm epigenetics and offspring health, including their brain function and dysfunction.
Coordinating Neuroimmune Sensory Networks In Health And Disease

Summary
Living organisms use cellular rhythms to optimize their energy use and cellular responses. Our proposal aims to produce significant new fundamental knowledge by elucidating the fundamental cellular and molecular biology of innate cells, their role in mucosal homeostasis and tissue repair pathways in the gut. Understanding this foundational process of cellular regulation will generate new basic knowledge and may lead to better management systems.
Understanding The Role Of DNMT1 SUMOylation In Acute Myeloid Leukaemia

Funding Amount
$639,290.00
Summary
Most cancers have abnormally high levels of DNA methylation, which turns off cell death genes, making cancer cells immortal. We have a new drug, called DNMT1i, that targets this feature of cancer cells and we recently found a new drug target that enhances the activity of DNMT1i. Our research will determine how these two drugs synergise to effectively kill cancer cells and will justify their use in clinical trials, which we believe will improve outcomes for patients with cancer.
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.
Vaccine To Prevent Influenza Virus And Bacterial Super-infection.

Funding Amount
$707,717.00
Summary
Influenza viruses have the ability to pre-dispose infected hosts toward secondary bacterial complications. The mortality of viral infections that are complicated by a concurrent, or subsequent, bacterial infection (known as a super-infection), is often greater than that of either the virus or the bacteria alone. We will develop a novel multi-pathogen vaccine candidate against the major upper respiratory tract pathogens - Influenza A and Streptococcus pyogenes to prevent super-infections.
Targeting Inflammatory Skin Disease Using An Immune-modulatory Human Signal Peptide

Funding Amount
$698,836.00
Summary
Effective drugs are desperately needed for the improved treatment of inflammatory diseases. We will determine how a modified human peptide, which we have discovered and can make, works to suppress harmful skin inflammation. We will design new formulations to deliver our drug to the skin in order to better treat psoriasis, an autoinflammatory skin disease. We will also trial our new drug in models of atopic dermatitis a debilitating skin disease for which there is limited treatment options.
Exploiting Anti-capsid Humoral Immunity Induced In Infants Receiving Gene Therapy For Spinal Muscular Atrophy To Engineer The Next Generation Of Gene Transfer Vectors

Funding Amount
$1,105,993.00
Summary
After 25 years of incremental progress the possibility of treating genetic disease by gene therapy has become a therapeutic reality. This has been achieved by harnessing the gene transfer power of viruses made harmless by genetic engineering. A major limitation is that up to 50% of patients are currently excluded by pre-existing immunity to these powerful tools. Using 'evolution in a dish', we will engineer a new generation of these tools capable of bypassing pre-existing immunity by stealth.
Inflammasome Sensors And Immune Protection Against Tumorigenesis

Funding Amount
$750,110.00
Summary
Intestinal cancer is a leading cause of death in Australia and worldwide. Defects in the immune system can lead to the development of intestinal cancer. In this project, we will investigate the critical role of an immune sensor in inhibiting the development of intestinal cancer. This project will provide new insights into the interplay between the immune system and cancer biology and will potentially inform the development of new immunotherapies.
Antibiotic Conjugates: Joining Together To Fight Antimicrobial Resistance
Funder
National Health and Medical Research Council
Funding Amount
$697,675.00
Summary
New strategies are urgently needed to treat the rise of infections from multidrug-resistant bacteria, with standard antibiotic therapies becoming obsolete. This project will develop multiple innovative approaches to overcome antibiotic resistance, based on a core concept of appending additional functionality to existing antibiotic scaffolds. New conjugates will be synthesized, tested for antimicrobial activity, then optimized via a validated antimicrobial development pipeline.
Immunomodulatory Vaccines In The Treatment Of Peanut Allergy

Funding Amount
$678,899.00
Summary
Peanut allergy is the most common cause of food-induced anaphylactic reactions in Australia and is a major burden to our healthcare system. Current clinical practice advice dietary avoidance to prevent fatal anaphylactic responses. We propose the use of an immunomodulatory vaccine to re-write the immune response to peanut antigens, from an allergic to a tolerant phenotype. This study will provide novel insights into rational approaches for manipulating immune memory to food allergens.
