Summary
Melanoma is one of the most frequent cancers in Australia. Its growth depends on the rpoper delivery of nutrients and oxygen through blood vessels. This requires the formation of new blood vessels as the tumour grows. In this project we intend to understand the origin of the blood vessels that form in tumours and identify the stem cells that support them. We will use proof of principle experiments to determine whether removal of these stem cells allows the regression of melanoma tumours.
Congenital brain vascular malformations are a common cause of stroke and death in young patients. This project aims to develop a new treatment for these lesions that does not require surgery. We will use focussed radiation to change the cells lining the abnormal vessels so that they can be targeted with a new treatment that causes blockage of the vessels and prevents haemorrhage.
Role For Zinc And ZIP2 In The Action Of Nitric Oxide And In Vascular Protection Against Cigarette Smoke And Cardiovascular Disease

Summary
The NO/cGMP signalling pathway, which is central to cardiovascular physiology and protection against disease, is only fully effective when there are adequate levels of zinc in the vascular endothelium. This is especially important where zinc stores are depleted (elderly, smokers, diabetics and kidney disease). There is an urgent clinical need to implement strategies to monitor vascular Zn status. This application will explore the underlying science and translate these to the clinic.
VCAM-targeted Delivery Of Recombinant CD39 To The Endothelium Is Antithrombotic, Antiinflammatory And Ameliorates Ischaemia Reperfusion Injury.

Summary
Blockage of arteries with clots leads to heart attacks and strokes. Reestablishment of blood supply by clot-busting drugs or mechanical interventions paradoxically causes further organ injury. This is due to toxic chemicals generated by inflammatory processes and free oxygen radicals. We have created an unique drug that selectively targets blood vessels that are injured by process. The drug will deliver blood-thinning activity and reduce inflammatory stress selectively at the site of need.
Therapeutic Potential Of Inhibiting Eph/ephrin Signalling To Repair The Vascular Endothelium In Septic Shock

Summary
Septic shock is a life-threatening condition usually caused by bacterial infection in the bloodstream. More than 5000 people, including 500 children, die from sepsis each year in Australia. Worldwide, it is the most significant cause of death in children. Sepsis is associated with leakage of fluid and proteins through the cells lining the blood vessels. This project will develop and test a novel treatment for sepsis which focuses on reducing this leakage by blocking the Eph/ephrin proteins.
Engineered Cell And Exosome Therapy For Pulmonary Vascular Disease

Summary
Diseases affecting the blood vessels in the lungs cause early death and the currently available treatments are not curative. We will take advantage of the latest developments in the understanding of the molecular basis of these diseases to design and test a new treatment approach using cells and cell-derived products as a therapy.
Developing And Testing Pro-thrombotic Conjugates For Brain AVMs

Funding Amount

Summary
Rupture of brain blood vessel abnormalities causes stroke in children and young adults. In this project, we will test new methods for occluding abnormal vessels. We use radiation first to induce changes in the vessels, and then target those changes to occlude the vessels. Successful treatment requires combining targeting and clot forming agents. In this project we will test combinations of targeting and clotting agents. The most effective combination will be progressed towards clinical trials.

Summary
The recent years have seen a rise in interest in collecting stem cells for future therapies. One example is the commercial offer of banking cord blood stem cells upon birth. In this project, we propose that the placenta, always discarded at the end of pregnancy, is another organ with high numbers of stem cells especially able to make blood vessels. We will examine if these cells can be expanded and used in treatment of situations with a need of increased blood supply such as cardiovascular disor ....The recent years have seen a rise in interest in collecting stem cells for future therapies.

The major burden of type I diabetes remains its vascular complications including diabetes-accelerated athersclerosis.

Despite improved glucose control, diabetic individuals develop complications as a result of prior poor glycemic control. Although the development and progression of these diabetic complications is strongly associated with mean levels of glucose, recent studies suggest that the deleterious effects of early exposure to high levels of glucose persist for years even after treatment has returned glucose levels towards normal.Read moreRead less
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.
