Summary
Activation of immune cells is required to generate appropriate immune responses that protect is from disease caused by pathogens. The inability to receive the correct type of signals causes immunodeficiency. The PI3 kinase pathway is central to immune cell activation – and genetic errors in this pathwat compromise the functioning of immune cells. We will investigate the nature of these defects and pursue avenues of overcoming them using pharmacological inhibitors of the PI3K pathway.
Epigenetic Mechanisms That Regulate B Cell Differentiation And Memory B Cell Persistence To Provide Long-term Immune Protection

Summary
Memory immune cells remember antigens that have previously induced an immune response, and the ability of these cells to rapidly clear pathogens has led to successful vaccination programs. This project will study epigenetic changes during the formation of immune memory that results in protection against foreign antigens. Understanding these processes will assist in creating more effective vaccines and treatments for patients with immune disorders.

Summary
The ageing of the population is one of the major transformations being experienced by Australia’s population which will have major health implications. Recent studies have shown that many elderly individuals display ‘immune risk phenotype’ (IRP) which is characterised by a severely distorted immune system and human cytomegalovirus (CMV) infection. In this project we will investigate the mechanisms by which CMV alters cellular immune system and thus impacts on the host immunity against other path ....The ageing of the population is one of the major transformations being experienced by Australia’s population which will have major health implications.

Defining The Stage Specific Requirements For Bcl-2 Family Members In The Development And Maintenance Of B Cell Memory

Summary
Both vaccinations and pathogenic infections provoke an immune response. Our immune system ñmemorizesî this response, enabling a faster and stronger reaction upon re-encounter. This memory requires specialized cells of the immune system, some of which secrete antibodies and some of which patrol the body. Remarkably, these cells can live for decades in humans and provide immunity. In this project we will study the roles of specific proteins regulating the generation and survival of memory cells.
In Vivo Imaging Of Virus-specific T Cell Responses In The Skin

Summary
Effective vaccination against many viral infections such as Herpes Simplex Virus (HSV) may be achieved by directing the cells of the immune system to specific sites in the body where they can lie in wait against the disease. To direct the immune system in this way, we must first understand how immune cells orchestrate themselves in tissues. This project will utilise advanced imaging techniques to study immune cells in real time to understand how they protect against viral infections in the skin.
Elucidating The Critical Roles Of ILC1, NK Cell And Innate Memory In Immune Protection

Summary
Natural killer cells are innate cells that provide first line defense against infection and cancer. The recent discovery of a novel innate cell population has modified our vision of the early events necessary for immune protection. Understanding the role of these cells is critical as they could represent viable therapeutic targets. We have developed unique mouse models to experimentally target this population to determine how they are generated and their role in combating infection and cancer.
STAT3-mediated Regulation Of Human Antibody Responses

Summary
The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host. Individuals with primary immunodeficiencies have defects in the development and/or function of the cells of their immune system and are more susceptible to infectious diseases. This study will investigate such individuals to identify functions for specific genes and immune cells in order to understand the requirements for generating effective immune responses ....The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host.

The Opposing Genetic Networks Underlying Plasticity Of Humoral Responses

Funding Amount
$667,783.00
Summary
The immune system makes antibody to clear bacterial and viral pathogens. Specialised types of antibody are needed for different pathogens. This project will study genetic changes that determine the specificity of an antibody response. Regulation of these genes may prohibit production of antibodies and inflammatory mediators that attack the body rather than foreign pathogens. Understanding these processes will identify points of therapeutic intervention for patients with immune disorders.
Novel Targeted PEG Nanoparticles For Cancer Treatment And Monitoring

Funding Amount

Summary
We will develop novel targeted cancer therapies based on next generation nanoparticles. These particles will deliver highly potent drugs to tumours with less adverse effects to healthy organs. The ability to image the therapeutic can be used to detect diseases at early, potentially curable stages, identify patients likely to respond to certain treatments, and predict response to therapy. Our project has the potential to increase the survival of patients suffering from the most deadly cancer.

Ten percent of admissions to Australian hospitals are associated with harm to patients. Reporting of patient safety incidents is now widespread. Current methods, which rely upon humans to manually review incident reports, do not permit timely detection of safety problems and can no longer keep up with the growing volume. This study will be the first internationally to automate the monitoring of incident reports.
