While therapies to treat cancer have continued to improve one area that, in theory at least, shows great promise in the treatment of tumours is manipulating the immune system to effectively recognize and destroy cancerous lesions. Experiments in human and animal systems have clearly shown that the immune system has the potential to respond to tumour cells and trials of tumour vaccines are underway. It has recently become apparent that the immune responses to tumours may be inhibited by classes of regulatory immune cells. Eliminating these cells results in a more vigorous and effective anti-tumour response. This project will seek to discover the mechanisms of action of theses regulatory immune cells in order to devise more effective anti-cancer vaccines and therapies.Read moreRead less

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.
T cells are a central component of the immune system and without T cells the body is very vulnerable to infections. One subgroup of T cells is the killer T cells that are important for identifying and killing cells infected by viruses and bacteria. The immune system works to maintain T cell numbers at a fairly constant level and part of this process includes sending signals to the killer T cells from other cells via cell surface protein interactions and soluble mediators, such as cytokines. We h ....T cells are a central component of the immune system and without T cells the body is very vulnerable to infections. One subgroup of T cells is the killer T cells that are important for identifying and killing cells infected by viruses and bacteria. The immune system works to maintain T cell numbers at a fairly constant level and part of this process includes sending signals to the killer T cells from other cells via cell surface protein interactions and soluble mediators, such as cytokines. We have been studying killer T cells, which are missing a protein SOCS1. SOCS1 is important for switching off the signals generated by a group of cytokines. As a consequence of being unable to correctly regulate cytokine signals these killer T cells multiply inappropriately and contribute to disease development. Our current work is aimed at achieving a better understanding of the particular interactions between killer T cells and other immune system cells and the soluble factors that deliver important signals for maintaining killer T cells in the immune system. The ability to better understand the factors controlling the maintenance of killer T cells will enable us to more intelligently target the immune system ,which is important for improving vaccine strategies and cancer immunotherapy as well as for controlling T cells that are activated inappropriately, such as in autoimmune disease.Read moreRead less
