Summary
With seasonal epidemics and the continual threat of a pandemic, there is an urgent need for a one-shot universal vaccine that protects against different influenza strains. This can potentially be achieved by the activation of killer T cells. I will identify new virus targets presented by a highly conserved human protein. Killer T cell recognition of these targets may provide a unique opportunity to develop an improved vaccine.

Summary
Hospitalisation and death rates from influenza are high in the Indigenous population. There is an urgent need for one-shot universal vaccine that protects against seasonal and pandemic strains. T cells recognising conserved viral regions can elicit such protection. As T cells are restricted by proteins called HLAs, variable between different ethnicities, we will define T cell regions and their HLA restrictions in the Indigenous population to propose strategies for universal T cell-based protecti ....Hospitalisation and death rates from influenza are high in the Indigenous population.

Summary
Hospitalization rates and mortality from influenza are greatly increased in the Indigenous Australian population. As current vaccines are highly strain-specific, there is an urgent need for a one-shot universal vaccine that protects this vulnerable group against seasonal and pandemic influenza. Immunity provided by T cells is long-lasting, cross-protective and can prevent severe disease. Our findings will inform the design of effective T cell-based influenza vaccines for Indigenous populations.
Immunodominance And Protective Immunity In The Context Of A Complex Host-pathogen System.

Summary
In experimental infection models with simple organisms, pathogen-specific immune responses recognize only a small fraction of potential epitopes encoded by the genome. This phenomenon is termed immunodominance. We propose the first comprehensive study of immunodominance in humans in response to a complex pathogen, the Plasmodium parasite that causes malaria. This will provide valuable new knowledge of host-pathogen immunity and facilitate rational vaccine design.
Understanding The Complexity Of Antigen Presentation

Summary
I have developed and established the use of mass spectrometry to identify and quantitate ligands of antigen presenting molecules to understand the breadth of immune responses in a variety of human disease states including autoimmunity, cancer, infection and allergy. By embedding the technology in disease focussed research programs I will define the molecular bases of these diseases and the important immunological targets that will provide new avenues for therapeutic development and vaccines.
