Funding Amount
$292,639.00
Summary
When the bacteria that cause meningococcal disease invade cells, they use specialized cell surface pore proteins to hijack the human cell and maintain infection. This research will study the structure of these bacterial pore proteins to help understand how they function to subvert normal cellular processes, and this insight will be important in the development of new treatments for meningococcal disease.
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.
Identification Of The Plasmodium Falciparum Translocon That Exports Parasite Proteins Into Their Erythocytic Hosts.

Funding Amount
$409,027.00
Summary
Up to 10% of the world's population will suffer from malaria in any given year and for over a million this disease will be fatal. This devastating disease is caused by the parasite Plasmodium falciparum that infects and destroys our red blood cells. Infected red cells are greatly modified by the parasites so they can feed and avoid elimination by the human immune system. We wish to investigate the red blood cell modification process and assess it as a potential target for anti-malarial drugs.
Remodelling Of Bacterial Outer Membranes: Implications For Vaccine Development.
Funder
National Health and Medical Research Council
Funding Amount
$558,189.00
Summary
We have identified proteins located in bacteria that are responsible for growth and the transport of essential nutrients. We will use a combination of bacterial genetics, protein biochemistry and immunological techniques to fully characterize these proteins. This strategic knowledge has direct implications for vaccine development and National security, since similar species of bacteria were amongst the first biological weapons.
The functional organisation of the trans-Golgi network: From cultured cells to physiological systems. This research will result in a better understanding of the secretory pathway of all eukaryotic cells, a process of broad biological and biomedical significance. It will impact on cell biology in the broadest sense, from membrane biogenesis to lipid domain organization, as well as membrane transport, protein structure and protein targeting. Furthermore, this work will utilize and develop fronti ....The functional organisation of the trans-Golgi network: From cultured cells to physiological systems. This research will result in a better understanding of the secretory pathway of all eukaryotic cells, a process of broad biological and biomedical significance. It will impact on cell biology in the broadest sense, from membrane biogenesis to lipid domain organization, as well as membrane transport, protein structure and protein targeting. Furthermore, this work will utilize and develop frontier technologies of live cell imaging and RNA interference as a genetic tool to investigate functions of a protein family. By training post-graduate students and post-doctoral staff, it will contribute to the expertise of cell biology in Australia. International collaborations will enhance connections between Australia and overseas research.Read moreRead less
Molecular microscopy: protein and membrane dynamics in resting and activated T cells. The aim of this research, to understand the molecular organization and dynamics of the plasma membrane that underlie the signal transduction events, is at the very heart of understanding cell communication. T cell recognition and activation initiates an adaptive immune response to invading pathogens and structurally altered proteins that can be found in cancers. By providing functional insights into the molecul ....Molecular microscopy: protein and membrane dynamics in resting and activated T cells. The aim of this research, to understand the molecular organization and dynamics of the plasma membrane that underlie the signal transduction events, is at the very heart of understanding cell communication. T cell recognition and activation initiates an adaptive immune response to invading pathogens and structurally altered proteins that can be found in cancers. By providing functional insights into the molecular mechanism of T cell activation, we will not only provide fundamental knowledge of receptor signalling but also specific details of T cell receptort triggering that may lead to the development of new therapeutic strategies to control T cell activation.Read moreRead less
