He has found that there exist cells at these peripheral sites that are separate from the immune components that one finds in the blood and, more importantly, that provide a profound level of protection during new infection. He now propose to determine how best to induce this type of peripheral immune protection and how one can exploit these mechanisms for the purpose of infection control.Read moreRead less

Summary
Individuals who survive infections by a given pathogenic micro-organism are usually protected from subsequent infections by these same agents. This is the basis of adaptive immunity, which defines the body's ability to maintain a memory of prior infection or vaccination and in so doing, mount a far more effective response to subsequent infection by these agents. This proposal deals with the mechanisms by which this memory is maintained. It specifically focuses on cytotoxic T lymphocytes (CTL) wh ....Individuals who survive infections by a given pathogenic micro-organism are usually protected from subsequent infections by these same agents. This is the basis of adaptive immunity, which defines the body's ability to maintain a memory of prior infection or vaccination and in so doing, mount a far more effective response to subsequent infection by these agents. This proposal deals with the mechanisms by which this memory is maintained. It specifically focuses on cytotoxic T lymphocytes (CTL) which are leucocytes or white blood cells that kill virus infected cells. Using new technology which permits visualisation of CTL directed against specific viruses we are going to define what determines the survival and replacement of these memory cells over time. We will also identify the agents that alter the memory CTL's ability to deal with infections within localised sites in the body. In so doing, this work will provide valuable insight into approaches that can be used to better vaccinate individuals against infections by pathogenic viruses.Read moreRead less
