Summary
This research proposal is to investigate the molecular mechanism and function of a blood serum protein, histidine-rich glycoprotein (HRG), in protecting against tissue injury caused by inflammation and infection. HRG has been implicated in controlling important aspects of tissue injury by aiding removal of dead cells and pathogens. Understanding the role of HRG in these disease settings may allow the development of approaches for the treatment of inflammatory, autoimmune and infectious disease.

Summary
Alzheimer’s disease and beta amyloid toxicity: Alzheimer’s disease (AD) is the most common form of dementia and is characterized by progressive memory loss, confusion, and cognitive deficits. In 2011, an estimated 269,000 Australians are currently living with dementia and without a significant medical breakthrough soon, it is anticipated that this will rise to about 981,000 by 2050
The cell is the building block of life. This proposal focusses on the surface of the cell, the plasma membrane, and specialised structures called caveolae that are an abundant feature of animal cells. Altered caveolae are a feature of many human disease conditions. In this proposal we will address the function of caveolae. We will test the idea that proteins are released from caveolae into the cell when cells are stressed forming a novel signalling pathway disrupted in disease.
Prof Parton is a cell biologist studying how the plasma membrane functions in health and in disease. These studies have provided new insights into potential vehicles that can be used to introduce therapeutic agents into cells.
Molecular And Functional Characterisation Of Cell Surface Microdomains

Funding Amount
$4,803,731.00
Summary
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 combating the changes associated with cell transformation in cancer and in other human diseases such as muscular dystrophy.
