Targeting The Synaptic Actin Cytoskeleton In Alzheimer's Disease

Summary
Dementias have become one of the fastest growing sources of major disease burdens in developed countries with about one in fifteen Australians older than 65 being affected. We will study how pathological stimuli disrupt nerve cell connections in the brain by impacting on the cellular architecture at these connections. Findings from our study will provide profound new insights in how nerve cells communicate with each other and how this communication is breaking down in disease.
Targeting Post-synaptic Tau To Treat Alzheimer's Disease

Summary
We have previously identified post-synaptic tau as being critical in mediating toxicity in Alzheimer's disease brains. This project aims at understanding the exact underlying molecular mechanisms and, more importantly, developing novel drugs to block early toxicity that initiates cascades that eventually lead to brain atrophy and dementia. To achieve this aim, this project will generate and utilize models of Alzheimer's disease in combination with a broad range of latest analytical tools.
Astrocyte Regulation Of Ammonia And Glutamate In Neonatal Hypoxia-Ischaemia

Summary
Lack of oxygen is a common problem for newborn infants, ocurring during events such as a difficult labour, and can lead to brain damage. We have discovered that a protein in the brain which normally removes ammonia (a toxic product of metabolism) is rapidly lost after a brief period of low oxygen. We propose that a build up of ammonia in the brain may be a key damaging event in hypoxia-related brain injury, and that it will be ameniable to therapeutic intervention.
