A fundamental study of the role of signal transduction pathways in the regulation of Chlamydia's complex developmental cycle. Chlamydia are unique organisms in the microbial world. They are among the smallest bacteria and yet have a complex two-stage developmental cycle. In addition they are major causes of disease in animals and humans with no vaccines available. We have used the recent flood of full genome sequence data to identify over 30 new cell signalling proteins. By understanding how the ....A fundamental study of the role of signal transduction pathways in the regulation of Chlamydia's complex developmental cycle. Chlamydia are unique organisms in the microbial world. They are among the smallest bacteria and yet have a complex two-stage developmental cycle. In addition they are major causes of disease in animals and humans with no vaccines available. We have used the recent flood of full genome sequence data to identify over 30 new cell signalling proteins. By understanding how these cell signaling proteins are organized into pathways and how this microorganism controls its complex growth and developmental cycle, we will be able to develop novel methods of control. We are at the fore front of international research and therefore uniquely placed to conduct this project.Read moreRead less
The protein O-glycosylation pathway of Neisseria: a model system for O-glycosylation of bacterial proteins with potential use in biotechnology. Proteins can be modified by the addition of sugar molecules. This process, called glycosylation, has been studied for some time in humans and other higher organisms, but is relatively new in the field of bacteria. This study will use the bacterium Neisseria as a model system for this process and work to harness the system for use in biotechnology.
Noncanonical epitope recognition by CD8+ T lymphocytes. This proposed research program will provide significant fundamental insight in the areas of immunology and vaccine design. Vaccines for many diseases remain elusive, and this project aims to improve our understanding of the precise regions within pathogens that are the targets for the killer T cells of the immune system. These regions, called epitopes, are likely to be key ingredients in many future vaccines. Although immunologists have gat ....Noncanonical epitope recognition by CD8+ T lymphocytes. This proposed research program will provide significant fundamental insight in the areas of immunology and vaccine design. Vaccines for many diseases remain elusive, and this project aims to improve our understanding of the precise regions within pathogens that are the targets for the killer T cells of the immune system. These regions, called epitopes, are likely to be key ingredients in many future vaccines. Although immunologists have gathered much information about such epitopes, recent studies have shown that some unexpected regions of pathogens are targets for killer T cells. This project will break new ground by utilising unbiased procedures to assess the relative contribution of these noncanonical epitopes to immunity.Read moreRead less
Interspecies electron transfer in biotechnology. While the project is fundamental in nature, it has direct technological gains to a wide range of biotechnology processes, and in particular, mixed culture anaerobic biotechnology. It therefore promotes Australian bioenergy, biofuel, and commodity renewable chemicals industries, and contributes to the national research priority of an Environmentally Sustainable Australia. In addition, this is a fast moving, high impact area that will demonstrate e ....Interspecies electron transfer in biotechnology.

It therefore promotes Australian bioenergy, biofuel, and commodity renewable chemicals industries, and contributes to the national research priority of an Environmentally Sustainable Australia. In addition, this is a fast moving, high impact area that will demonstrate excellence in Australian research on an international scale. The exciting multidisciplinary nature of the project, excellent management team, and high-class partners will also provide for an excellent experience for the three PhD candidates to be educated through the project.Read moreRead less
An interdisciplinary approach to host-pathogen interactions in infection. This project aims to understand the molecular and cellular interactions between host and parasite, as well as providing a quantitative framework for analysing infection dynamics in other systems. Infection involves a complex interaction between the host and the parasite, which is very dynamic and therefore difficult to study by traditional sampling and analysis approaches. This project has combined mathematical modelling w ....An interdisciplinary approach to host-pathogen interactions in infection. This project aims to understand the molecular and cellular interactions between host and parasite, as well as providing a quantitative framework for analysing infection dynamics in other systems. Infection involves a complex interaction between the host and the parasite, which is very dynamic and therefore difficult to study by traditional sampling and analysis approaches. This project has combined mathematical modelling with a novel experimental protocol to allow the study of kinetics of parasite replication in vivo. Expected outcomes will provide significant benefits, such as new avenues for vaccination and immune intervention.Read moreRead less
Slipping out unnoticed: a new bacterial lipoprotein transport system. Worldwide markets for biotechnology-derived products are projected to grow to at least $50 billion per year for the next 10 years. The cornerstone of biotechnology is the production of proteins. The applicant has discovered a new pathway for protein production in bacteria. The primary objective of this project is to use a diverse array of biochemical and biophysical techniques to understand how this new protein production pl ....Slipping out unnoticed: a new bacterial lipoprotein transport system.

The applicant has discovered a new pathway for protein production in bacteria. The primary objective of this project is to use a diverse array of biochemical and biophysical techniques to understand how this new protein production platform works. We will also assess this new pathway for the production of proteins of interest to the biotechnology sector. This project expects to determine how this system can be exploited for use in the growing Australian bioeconomy.Read moreRead less
