Summary
Neurons in the brain are connected by synaptic contacts. Amyloid beta peptide accumulating in the brain in Alzheimer’s disease destroys synaptic contacts by degrading synaptic cell adhesion molecules which maintain the structure of the contacts. The aim of the project is to characterise the molecular mechanisms of amyloid beta-dependent degradation of synaptic cell adhesion molecules. The project will identify strategies that can be used to inhibit synapse loss in Alzheimer’s disease.

Summary
In Down syndrome, an extra copy of chromosome 21 increases gene expression and leads to brain defects. We hypothesise that one candidate gene, Dscam2, changes its function with increased expression. This causes brain cells that normally stick to each other to repel each other, leading to inappropriate connections in the brain. We will test this model in the fruit fly and demonstrate for the first time a mechanism dependent on gene expression that can lead to brain abnormalities in Down syndrome.
Failure to correctly regulate cell death leads to a number of diseases, including cancers and auto-immune diseases. Viruses have the ability to hijack the host cell death machinery for their own benefit. Viral infections have been linked to a number of cancers. We aim to target the ability of viruses to hijack the process of cell death to develop new treatments against virus-linked cancers including Burkitt's Lymphoma and Nasopharyngeal Carcinoma.

Summary
Transplantation of patients’ own blood stem cells is used to treat many blood cancers. It increases the chance of cure. However the damage caused by chemotherapies used to combat the cancer can compromise stem cell collection and transplantation. Without transplant, these patients are less likely to survive cancer. This project is to test new drugs that enhance the harvest of blood stem cells for transplantation. These will increase the success rates of transplants and cure in these cancer patie ....Transplantation of patients’ own blood stem cells is used to treat many blood cancers.

Summary
Collectively, diseases of the blood vascular system contribute immensely to the burden of health care in Australia. Notably, abnormal blood vessel formation is a major cause or contributor to many diseases, such as cancer, cardiovascular disease, rheumatoid arthritis, ischemia injury and diabetes. This project aims to understand the underlying mechanisms associated with aberrant angiogenesis such that it may aid in the identification of novel targets for the development of therapeutics.
