Characterisation And Targeting T Cellular Metabolism To Improve Control Of Chronic Viral Infections

Summary
CD8+ T cells are the frontline warriors of our immune system that can eliminate infected or cancerous cells. However, diseases caused by overwhelming viral infections are associated with widespread impairments in immunity and cellular metabolism. Here, we propose to examine molecular pathways involved in cellular metabolism that could be utilized to improve therapies against viral infection and cancer.
Determining Immune Dynamics During Controlled Primary Infection In Humans

Funding Amount
$579,823.00
Summary
T cells are critical to human health being our second and last line against infectious disease and cancer. However, we know very little about how this hugely complex immune compartment operates during primary challenge with infectious disease. This project will use new technologies to resolve this immune compartment to high detail during the days, weeks and years following controlled infection in human volunteers.
Dendritic Cells Govern The Balance Between Immunity And Homeostasis To Inhaled Antigen

Summary
The development of better intranasal vaccines hinges on the improved understanding of how the immune response is initiated following vaccine delivery into the upper airways. In this project we will provide fundamental understanding of how immune responses to inhaled antigens are regulated; this considerable conceptual advance will lay the foundation for which new intranasally delivered immunotherapies will ultimately emerge.
HARNESSING T CELL QUALITY FOR PANDEMIC PREPAREDNESS

Summary
Developing highly effective vaccines is critical to rapidly combat global pandemics. To generate a protective antibody response against novel viruses, a vaccine must elicit a targeted B cell response supported by effective CD4 T cell help. We propose that existing CD4 T cell memory can be harnessed to rapidly and effectively support B cell responses to novel vaccine candidates. This work will contribute to pandemic preparedness strategies and improve the development pathway for new vaccines.
Developing Improved Therapies For Cytomegalovirus Infections By Overcoming Viral Strain Diversity.

Summary
Cytomegalovirus infection is the most common cause of infection-related disease in newborns and is one of the most common complications in transplant patients. Current treatments are not always successful and are associated with significant side-effects. We have therefore developed world first systems that can be used to develop safer, more effective treatments for this life-threatening infection. Our findings are likely to be applicable to other difficult to manage viral infections.
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.
Tolerising Antigen-specific Immunotherapy For Type 1 Diabetes

Funding Amount
$1,395,549.00
Summary
We have developed a new immunotherapy to treat the underlying causes of type 1 diabetes (T1D) while leaving the rest of the immune system intact. To use this in patients, we need better tests to know when immune therapy is working. We will develop new methods to design the therapy and tools to track the relevant immune cells in T1D that work in variable patient groups. The knowledge gained will speed the pace of development and increase the chance of success of immunotherapy in T1D.
Repurposing Thalidomide Derivatives To Augment Cancer Immunotherapy

Funding Amount
$1,154,196.00
Summary
Immunotherapies are a revolutionary approach for cancer treatment, but most people with cancer do not respond to therapy. We have identified a new set of molecular switches that shutdown immune function and limit responsiveness to existing immunotherapies. Importantly, we have found a class of approved drugs that can block these immune 'off switches'. This proposal will test if these drugs could be repurposed as a novel treatment to amplify the efficacy of existing immunotherapies.
Reprogramming Human Fibroblasts Into Induced Trophoblast Stem Cells

Funding Amount

Summary
We have been able to generate artificial human trophectoderm which is the tissue that creates the placenta. This will allow us to do research in how the genes control the fate of these cells without the need of human embryos or placenta. We anticipate that the derivation and characterising these cells will revolutionise placenta research, which in turn will contribute to the establishment of new therapies for placenta disease and infertility.
Growth Factor Directed Developmental And Pathological Lymphangiogenesis

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.
