This research program aims to gain a detailed understanding of the organisation of the cell surface at the molecular level. The cell surface is organised into domains with distinct functions. Visualisation of these domains, identifying their important components, and understanding how they form and function will have huge importance for therapeutic strategies aimed at combatting the changes associated with cell transformation in cancer and in other human diseases such as muscular dystrophy.
Membrane Attachment And Components Of The Ca2+ -triggered Release Mechanism

Summary
Understanding and harnessing the fundamental cellular process of secretion will provide a wealth of new approaches to addressing problems associated with aging & disorders that are major health care burdens (e.g. neurodegeneration & diabetes). Understanding the vesicle docked state, and the contributions of different molecular components to the release process provides for unique insights into the underlying molecular mechanisms, thereby enabling safe, targeted control of this critical process.
Multiscale Analysis Of Plasma Membrane Microdomains In Health And Disease

Funding Amount

Summary
The cell surface encloses the cell in a protective barrier but it must also respond to signals coming from outside the cell. To accomplish this, the cell surface is made up of numerous regions each with a specialised role. This proposal aims to examine how lipids and proteins work together to make these specialised regions and aims to understand what goes wrong in diseases such as muscular dystrophy.
Pathophysiology And Alternative Preventative Strategy For Breast Cancer Chemotherapy-induced Bone Loss

Summary
Combination cytotoxic chemotherapy is the current optimal approach for treating breast cancer in premenopausal women. However, long-term skeletal defects (osteoporosis and fractures) caused by the chemotherapy have become an increasingly serious problem due to its intensified use and improved patient survival rate. This project seeks to elucidate the mechanisms for chemotherapy-induced bone defects and to initiate development of a preventative treatment using natural bioactive micronutrients.
The regulation to early T cell signalling is a critical step in immune responses. Superimposed onto the biochemical pathways is a spatial organization that defines the immunological synapse. My research aims to map the principles of the spatial organization on the molecular scale to identify how lipids could unbalance the dynamic signalling equilibrium, for example in obese patients. To achieve this goal, my research group has developed single molecule microscopy approaches.
Understanding The Mechanisms Of Functionally Selective Antipsychotic Drugs: Implications For New Generation Antipsychotic Drugs

Funding Amount

Summary
Schizophrenia is a chronic and devastating disease that ranks among the top 10 disabilities in developed countries. It places a significant burden on the Australian health system, costing about $1.5 billion each year. This project aims to reveal the mechanisms of new functionally selective antipsychotic drugs, which achieve an excellent therapeutic efficacy with low side-effects. Understanding these mechanisms will provide novel directions for the design of new generation antipsychotic drugs.
New Drugs To Counteract The Side Effects And Premature Ageing Caused By Chemotherapy

Summary
During cancer treatment, commonly used chemotherapy drugs cause profound side effects that include pain, nausea, heart problems, hair loss and can affect almost every system in the body. Even after chemotherapy treatment has stopped, cancer survivors face an increased risk of diseases which resemble the effects of old age. We are testing newly discovered anti-ageing molecules for their ability to reduce these side effects, and drastically improve the quality of life for cancer patients.
