Summary
The axon is the primary signaling component of every neuron and is essential for normal function. Axonal degeneration is a key early pathological hallmark of Alzheimer’s disease. We lack a basic understanding of molecules that regulate this process. Such knowledge is essential for the development of treatments and therapies for dementia and the preservation of healthy ageing. I aim to discover the molecules that regulate axonal degeneration and study their function.
Cytotoxic lymphocytes are immune cells responsible for the killing infected or cancerous cells. How cytotoxic lymphocytes mature from a naive inactive to a fully activated state as they encounter infected or malignant cells is poorly understood, and will be investigated in the current proposal. Our results will aid in the development of novel therapies for cancer and other immunological diseases.

Summary
A major challenge for transfusion medicine is the constant difficulties in obtaining enough supply of specific red blood cell (RBC) subtypes. In this proposal, we will identify the key steps of enucleation (extrusion of nucleus), a rate limiting process for the in vitro production of RBCs. A better understanding of this process will lead to improved strategies for the efficient and rapid production of self-generated RBCs for individual patient transfusion.
Investigating The Cellular Response To Iron-Depletion: The Trilogy Of ASK1, Thioredoxin And Ribonucleotide Reductase

Summary
Iron is crucial for many essential biological processes. Recently, we demonstrated that iron-depletion can affects important signalling pathways (e.g., JNK and p38) that play important roles in growth arrest and apoptosis. This study is designed to investigate the cellular and molecular effects of iron depletion which currently remains unclear. The research is crucial for understanding: (1) the effects of iron deficiency and (2) for understanding the effects of iron chelators that are used for t ....Iron is crucial for many essential biological processes.

Cellular Pathogenesis Of Key Proteins Involved In Neurodegenerative Disorders

Summary
Prion proteins are involved in neurodegenerative diseases such as Creutzfeldt-Jakob disease (CJD) and Bovine Spongiform Encephalopathy (BSE). The aim of this research proposal is to investigate factors which can change the prion protein from a normal, benign, form into an abnormal shape which can cause disease. The outcomes of this work will provide further insight into the role of prion proteins in these diseases and also for other neurodegenerative disorders such as Alzheimer's disease.

Summary
It is well accepted that the cells in the local environment of cancers can help to promote the growth and spread of tumour cells. We have shown that a cell type known as the pericyte previously thought to be involved in controlling tumour expansion by affecting new blood vessel formation, may directly influence tumour growth, a notion that will be tested in human skin and ovarian cancer models. We will also test if pericyte markers can predict those cancer patients at greater risk of relapse.
Axonal Fusion To Promote Nerve Repair: Molecules And Mechanisms.

Summary
Nerve injuries are in most cases untreatable, leaving patients with high level of disabilities for the rest of their life. Understanding the molecular mechanism regulating nerve regeneration is critical to develop new drugs and design innovative therapies. We discovered molecules that mediates axonal repair by favouring the stitching together of the two separated fragments of an axon. We aim to study how they functions to possibly exploit a similar mechanism of repair for human injuries.

Summary
Addressing the WHO Radiofrequency (RF) Research Agenda, this CRE brings together Australia’s strongest RF-health researchers to safeguard the Australian community within its ever-burgeoning RF exposure environment. It will determine the potential for RF-induced harm in the community and how best to communicate this knowledge to the community, translate this knowledge to the community via focused strategies, and develop Australia’s RF-health research and communication capability for the future.
