Summary
Cell migration is an essential feature of physiological processes involved in embryo development, as well as disease conditions such as cancer metastasis. Cell movement requires extensive changes to the cell surface. We have identified a vital pathway involved in membrane trafficking during cell migration. This proposal aims to identify the cellular components involved in this pathway, screen for new inhibitors, and characterise the role of this pathway in migrating cancer cells.
Peripheral Membrane Proteins In Health And Disease

Summary
Peripheral membrane proteins are critical for processes such as cell transport, signaling, neurosecretion and development. As such, their dysfunction can lead to many debilitating diseases including cancer, inflammation and neurodegeneration. This project will establish fundamental new knowledge about how peripheral membrane proteins regulate cell function, how their perturbation or mutation results in human disease, and will inform efforts to target them for future therapeutic outcomes.
A Signalling Endosomal Network In T Cell Activation

Summary
T lymphocytes play a central role in the adaptive immune response, which specifically targets pathogens and cancer cells and creates the immunological memory. Activation of sometimes as little as one single receptor on a T cell triggers a cellular signal that rapidly expands and branches out in a multitude of sub-signals. Here we will use a combination of novel microscopy approaches to visualise how a network of dedicated intracellular compartments is in charge of these processes.

Summary
Abnormal subcellular distribution of cholesterol is associated with a number of common diseases including heart disease and Alzheimer’s disease. The overall aim of this proposal is to identify and characterize novel molecules that regulate the transport of intracellular cholesterol. Results from the proposed studies will provide important insights into the molecular mechanisms governing intracellular cholesterol transport and distribution, and will lead to better treatment strategies against hea ....Abnormal subcellular distribution of cholesterol is associated with a number of common diseases including heart disease and Alzheimer’s disease.

Development Of Effective Biomarkers For The Diagnosis And Prognosis Of Prostate Cancer

Summary
Every year ~20,000 Australian men are diagnosed with prostate cancer and more than 3,000 die of this disease. The current PSA test for the diagnosis of prostate cancer is not specific and this can result in incorrect diagnosis, unnecessary biopsies and lead to wrong treatments. We have discovered a novel change in the biology of prostate cancer. We will use this information to develop new tests for prostate cancer, which provide early accurate detection and can predict disease progression.
Infectious pathogens invade cells by hijacking cellular pathways, termed endocytosis, that normally internalise material from outside the cell. We will identify the molecular details of these pathways and how they are modulated in response to infection with Salmonella, a leading cause of human gastroenteritis. Such studies are necessary in order to understand host-pathogen interactions so that treatments can be developed targeting the symptoms of infection
Membrane Trafficking Of BACE1 And Amyloid Precursor Protein In Primary Neurons And The Production Of Abeta Amyloid Peptides

Summary
The development of Alzheimer’s disease results from the generation of toxic peptides by the cleavage of a membrane protein by an enzyme called BACE. A key feature of which regulates the generation of toxic peptides involves the movement of BACE between compartments in the cell by a process known as membrane transport. Our recent work has identified the itinerary of BACE in the cell. The studies here will reveal the molecular machinery of the BACE pathway in neurons. This fundamental informati
