Summary
The ability to modulate immune responses would have major health benefits. Dendritic cells (DC) are key regulators of the immune system. Different types of DC possess different cell surface molecules and have differing regulatory functions. We have identified four novel DC surface molecules that can be used to target different types of DC. We aim to use antibodies against these molecules to either enhance the effectiveness of vaccines or to suppress autoimmune diseases.

Summary
The mucosal surfaces are the entry site for many pathogens (eg. cholera, rotaviruses, helicobacter, SARS and sexually transmitted diseases including HIV infections). The ideal vaccine would elicit both systemic and mucosal immune response, enhancing immunity at this first line of defence. The oral route has formidable barriers to antigen uptake such as digestive enzymes, commensal microbes, mucous layers and gastric acid. Our strategy targets the vascular addressin found in immune tissues of the ....The mucosal surfaces are the entry site for many pathogens (eg. cholera, rotaviruses, helicobacter, SARS and sexually transmitted diseases including HIV infections). The ideal vaccine would elicit both systemic and mucosal immune response, enhancing immunity at this first line of defence. The oral route has formidable barriers to antigen uptake such as digestive enzymes, commensal microbes, mucous layers and gastric acid. Our strategy targets the vascular addressin found in immune tissues of the gut (called MAdCAM) so that the vaccine is linked to an antibody against MAdCAM. Thus for the first time we believe that a parenteral vaccine ie. injected im or iv (bypassing the oral barriers) can induce mucosal immunity.Read moreRead less
Understanding immune mechanisms induced by pulmonary vaccination. This project aims to better understand the mechanisms of immune induction of a novel lung vaccination strategy. The ability to deliver vaccines that induce potent lung and body wide immune responses in a safe and efficient manner has wide implications for both human and animal health. Ultimately, the vaccine will be delivered to the lung as stable dry powders in an attempt to negate the need for a transport cold chain and therefor ....Understanding immune mechanisms induced by pulmonary vaccination. This project aims to better understand the mechanisms of immune induction of a novel lung vaccination strategy. The ability to deliver vaccines that induce potent lung and body wide immune responses in a safe and efficient manner has wide implications for both human and animal health. Ultimately, the vaccine will be delivered to the lung as stable dry powders in an attempt to negate the need for a transport cold chain and therefore facilitate the distribution of the vaccines to remote areas. The project will not only benefit the Australian biotechnology industry but also the community at large and in particular those in remote areas without access to modern medical facilities.Read moreRead less
Development and Assessment of Chimaeric Feline Caliciviruses as Vaccines. Feline caliciviruses are major pathogens of cats worldwide, but current vaccines offer only incomplete protection. This project aims to develop novel recombinant vaccine strains that will generate more cross protective immunity and thus provide greater protection for vaccinated cats.

Summary
Bacterial infectious diseases are a serious threat to human health, accounting for over 10 million deaths each year. This multidisciplinary collaborative team is investigating the complex interactions between major disease-causing bacteria and their human hosts, in order to determine how they cause disease. These studies will make a major contribution to fundamental knowledge in this field. This information is also essential for the development of cheaper and more effective vaccines, as well as ....Bacterial infectious diseases are a serious threat to human health, accounting for over 10 million deaths each year. This multidisciplinary collaborative team is investigating the complex interactions between major disease-causing bacteria and their human hosts, in order to determine how they cause disease. These studies will make a major contribution to fundamental knowledge in this field. This information is also essential for the development of cheaper and more effective vaccines, as well as novel drugs. These are urgently needed to reduce death and illness due to bacterial infectious diseases in the 21st century. 11Read moreRead less
Molecular determinants of an allergic response. Some humans develop allergies after exposure to environmental allergens while others do not. At present, the reason for this individual variation is not known. By comparing the processes activated in allergic versus non-allergic individuals, this study will identify critical molecules involved in making individuals susceptible to allergies, which will be used to develop safer and more effective allergy vaccines.
Development of an Attenuated Infectious Laryngotracheitis Virus Vaccine. This project will develop novel methods for identification of genes involved in virulence of the important avian pathogen Infectious Laryngotracheitis Virus and produce an attenuated, antigenically marked infectious laryngotracheitis virus vaccine strain by specific disruption and deletion of two or more genes in the virusÕs genome.
Infectious laryngotracheitis is a major disease of chickens throughout the world, but curre ....Development of an Attenuated Infectious Laryngotracheitis Virus Vaccine. This project will develop novel methods for identification of genes involved in virulence of the important avian pathogen Infectious Laryngotracheitis Virus and produce an attenuated, antigenically marked infectious laryngotracheitis virus vaccine strain by specific disruption and deletion of two or more genes in the virusÕs genome.
Infectious laryngotracheitis is a major disease of chickens throughout the world, but current vaccines retain some capacity to cause disease. The development of novel attenuated vaccines will thus enhance control of this important disease of poultry.Read moreRead less
