Summary
Killer T lymphocytes are a diverse population which vary in their ability to recognise infected cells. This study aims to determine whether vaccine dose and frequency impact on the generation of highly sensitive killer T cells. This study will improve our basic knowledge of killer T lymphocyte selection during infection and have application to improved methods of vaccination.

Summary
This research will begin to determine the significance of changes in the amount of a recently-discovered protein on the surface of tumour cells. We have shown that an increase in expression of this protein protects tumour cells from destruction by our immune system's killer T cells. The outcome of this research could lead to a better understanding of how the immune system recognises and kills tumour cells, and ultimately, alternate vaccine strategies for tumours.
Epigenetic Regulation Of CD8+ T Cell Function And Memory.

Summary
Upon virus infection, a subset of white blood cells, called killer T cells, are recruited to fight the infection. This proposal aims to examine molecular changes that occur within killer T cells and impart their specific function. We also aim to understand how killer T cells are _programmed� as they establish immunological memory. This proposal will provide insights important for the design and improvement of vaccine strategies to fight pathogens such as influenza, HIV and even tumors.
Studies On The Role Of The P101 Component Of The Class 1B PI 3-Kinase In Cell Migration And Activation.

Summary
This research will determine the biological role of a protein of unknown function that is likely to participate in movement of white blood cells through the body. The outcome of this research will increase our basic knowledge of how the immune system functions and could lead to alternate therapeutic strategies for the control of autoimmune diseases.

Summary
B cells produce antibody which is critical to fight infection. In order to perform this function, antibody genes must first be modified by immune enzymes. However, abnormal DNA attack by these enzymes outside of antibody genes can result in B cell cancer. How the immune system detects and destroys cancerous B cells is poorly understood. This research will provide insight into these processes, and in doing so will further our understanding of how B cell cancers develop and how they are destroyed.
