Poly(amino acids) as immune stimulators. This project aims to develop nanoparticles built from natural hydrophobic amino acids as an immune stimulatory delivery system for peptide antigens. Currently available immune stimulants (adjuvants) are often toxic and/or are poorly chemically defined fragments of bacteria or toxins and vary from batch-to-batch. New adjuvants are in high demand; especially to facilitate the use of optimal, but weakly immunogenic, peptide antigens. It is expected that the ....Poly(amino acids) as immune stimulators. This project aims to develop nanoparticles built from natural hydrophobic amino acids as an immune stimulatory delivery system for peptide antigens. Currently available immune stimulants (adjuvants) are often toxic and/or are poorly chemically defined fragments of bacteria or toxins and vary from batch-to-batch. New adjuvants are in high demand; especially to facilitate the use of optimal, but weakly immunogenic, peptide antigens. It is expected that the proposed project will develop a novel efficient, safe and notably biodegradable self-adjuvanting delivery system that can be fully customised to match an antigen of choice. This foundational research should provide important advances for commercial immune stimulatory applications.Read moreRead less
Phasevarions of Haemophilus influenzae: mechanisms and origins of a novel epigenetic system controlling coordinated random switching in expression of multiple genes. Central to the utilisation of biological information is our ability to identify and interpret DNA sequence information from genomes. In bacteria that cause disease, these investigations can identify key aspects of the infectious process or potential components of vaccines or new targets for antibiotics. Our recent work has identifie ....Phasevarions of Haemophilus influenzae: mechanisms and origins of a novel epigenetic system controlling coordinated random switching in expression of multiple genes. Central to the utilisation of biological information is our ability to identify and interpret DNA sequence information from genomes. In bacteria that cause disease, these investigations can identify key aspects of the infectious process or potential components of vaccines or new targets for antibiotics. Our recent work has identified a new genetic system, the 'phasevarion', that mediates random expression of multiple genes. The proposed research aims to advance our understanding of gene expression at the most basic level, revealing how bacteria generate diverse populations to evade environmental and immune stresses, and facilitating improved interpretation and use of DNA sequences for researchers and industry in this field.Read moreRead less

The project aims to develop a new single-dose, room temperature-stable nanovaccine for cost-effective influenza poultry vaccination. The nanovaccine is based on viral protein assembly modularised to present multiple copies of influenza antigen. Particularly, this project focuses on the engineering of this vaccine manufacturing and formulation for a room temperature-stable vaccine. The resulting engineered vaccine would play an important role in preventing avian influenza outbreaks, which are currently affecting both developed and developing countries, costing millions of dollars due to the death and culling of infected poultry.Read moreRead less

Phase-variable epigenetic regulators in bacterial veterinary pathogens. This project aims to identify phasevarion regulated genes in the major bacterial swine pathogens Streptococcus suis and Actinobacillus pleuropneumoniae. Both species contain randomly switching epigenetic regulators that control expression of multiple genes by epigenetic mechanisms. Identifying phasevarion controlled genes will inform and direct future vaccine development for important livestock species.

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
