Summary
T cells are the sentinels of our immune system continually scanning our tissue for abnormalities and eliminating threats in many forms. They are our second and last line of defence against microorganisms and cancer. Unfortunately, T cells can also cause harm through accidental crossreactvity or overzealous function. My work is directed at understanding how T cells work and how they can be controlled using drugs and gene therapy. If we can ‘tune’ the power of this master immune lineage we can unl

Summary
Killer T cells are a specialised group of immune cells, which destroy cancerous and infected cells. When killer T cells find a target, they attach and secrete toxic molecules. It then detaches from the dying target, so that it may go on to kill other cells. If it doesn’t detach properly, it remains bound to the target cell and results in an improper immune response. This proposal will investigate how the killer cell detaches, which is essential for an efficient immune response.

Summary
Our bodies rely on the production of antibodies to fight infection. The cytokine IL-21 is produced by immune cells called T follicular helper (Tfh) cells that help B cells make antibodies. Tfh cells, in turn, are controlled by regulatory (Tfr) cells. Our findings demonstrate that IL-21 supports Tfh cells and limits Tfr cells, thus favoring antibody production and long term immunity. Using genomic and cellular approaches, the mechanism(s) underlying these observations will be explored.
I am an immunologist, working to understand the function of NKT cells, and how these cells can be manipulated as a means of immune therapy for a range of immunologically related diseases.
Understanding the immune response is proving extremely complex and promising results for disease treatments from animal models are often difficult to translate to new clinical therapies. My research is unearthing weaknesses in our current knowledge of the immune system and seeking to replace them with a foundation that can exploit new developments in computer modelling and systems biology. In this way I aim to rationally manipulate the immune response.
Defining The Requirements For Effective Immune Responses

Summary
The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host. Individuals with primary immunodeficiencies have defects in the development and/or function of the cells of their immune system and are more susceptible to infectious diseases. This study will investigate such individuals to identify functions for specific genes and immune cells in order to understand the requirements for generating effective immune responses ....The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host.

Summary
T cell responses are important to establish protection against pathogens and some cancer via generation of memory cells that can be maintained long term and defeat promptly re-infections. This proposal aim at determining important factors that drive the success of immunological memory by employing single cell technologies and unique longitudinal samples from subjects infected with hepatitis C virus. The finding of this study will inform current vaccine research and immunotherapies.
