Summary
The aim of this project is to utilise novel mouse models and imaging techniques to unravel the role of an immune cell called neutrophil in controlling immune responses. We show that as the first cell to leave the site of bacterial infection neutrophils can orchestrate subsequent activation of other immune cells. We plan to investigate the mechanisms and consequences of this process with a view to uncover new neutrophil-based therapeutic strategies that would improve the management of inflammator ....The aim of this project is to utilise novel mouse models and imaging techniques to unravel the role of an immune cell called neutrophil in controlling immune responses.

Development Of A New Specific Immunosuppressive Monoclonal Antibody To Advance Transplantation

Funding Amount
$736,300.00
Summary
Current nonspecific immunosuppressive agents compromise post transplant protective responses, including the anti-tumour effect of a bone marrow transplant. We have developed an antibody (3C12C), that targets CD83 on activated dendritic cells as a new, more specific, immunosuppressive strategy. We will work with our commercial partner to develop the patented antibody as a new imunosuppressive agent, which retains anti-viral and anti-cancer responses. This would be a major advance for patients.

Summary
Australia has amongst the highest reported prevalence allergic conditions (including asthma) in the world. Despite this, little is known about how these conditions arise. Mounting evidence implicates environmentally induced disruption of the genetic blueprint via a process known as epigenetics. We are combining the strengths of a unique collection of identical twins where one of a pair is sensitive to house dust mite, with cutting edge genomics, to characterise the pathways leading to allergy in ....Australia has amongst the highest reported prevalence allergic conditions (including asthma) in the world.

ANTIGEN PRESENTATION IN CEREBRAL MALARIA PATHOGENESIS: A ROLE FOR BRAIN MICROVASCULAR ENDOTHELIUM AND MICROPARTICLES

Summary
We want to better understand how lesions occur in the brain during cerebral malaria. We focus our attention on the cells lining the brain blood vessels, called endothelial cells. The originality of this project is to study endothelial cells as immune cells. We already showed that they carry molecules enabling them to activate T lymphocytes and trigger inflammation. Knowing the fine mechanisms by which small brain vessels become damaged will help design better treatments for neuroinflammation.
Dendritic cells are essential components of our immune systems. They are located throughout our body and provide the first line of defence against invading microbes. Dendritic cells sense the invader and send out signals to recruit our immune cells to the site of infection. Our research aims to understand how our dendritic cell network is set up and how it functions to promote our immune health.
Dendritic Cells In Graft-versus-Host Disease Following Bone Marrow Transplantation

Summary
Bone marrow transplantation (BMT) is the only available curative therapy for many blood cancers such as leukaemia. Graft-versus-host disease (GVHD) occurs after BMT and is a major cause of transplant-related death. GVHD occurs when transplanted donor cells “attack” recipient tissues causing widespread damage. Gaining a more comprehensive understanding of this disease process is critically important for the design of new therapies and improvement of outcomes for transplant recipients.

Summary
Bone marrow transplantation (BMT) is the most effective treatment for a number of haematological conditions, especially leukemia. Graft versus host disease (GVHD) is a complication of BMT and results in the death of up to 50% of transplant recipients. GVHD occurs when the newly transplanted immune system recognizes the recipient as foreign and mounts and immune reponse against the patients tissues. These studies will focus on identifying and understanding the function of the immune cells which d ....Bone marrow transplantation (BMT) is the most effective treatment for a number of haematological conditions, especially leukemia.

Identifying Molecular Machinery In Dendritic Cells.

Summary
Vaccines invoke immune responses that will protect a vaccinated host if they encounter infection. Vaccines can also be deployed to fight cancer. 'Dendritic cells' are the key immune cell responsible for vaccine immunity. While dendritic cells are pivotal to initiating vaccination, little is known about their internal machinery. This research proposal will identify new machinery for dendritic cell vaccine immunity that will serve as therapeutic targets to boost vaccination.
