Summary
Autosomal recessive hyper IgE (AR-HIES) syndrome due to mutations in DOCK8 is a rare primary immunodeficiency whereby patients present with susceptibility to severe and recurrent viral infections as well as an increased risk of developing cancer, severe food and environmental allergies, and atopic disease characterised by hyper IgE and extreme eosinophilia. This grant will investigate how abnormal DOCK8 function in CD4+ T cells and B cells contributes to disease pathogenesis in AR-HIES patients.
Utilising Human Primary Immunodeficiencies To Study Lymphocyte Differentiation

Summary
Human immunodeficiencies are diseases arising from naturally occurring mutations. In this instance, the specific genes mutated in the immunodeficiencies we study have been identified. However, it is unclear how defects in these genes make an individual manifest as an immune deficient state, rendering them vulnerable to disease. By studying immune cells from these individuals we hope to uncover the normal function of these genes and subsequently provide for new therapies for these conditions.

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
Characterisation Of An Antigen Presenting Cell Unique To Spleen

Summary
The body depends on a range of defence mechanisms to remove invaders that enter by various routes. Antigen presenting cells are central to immunity in that they engulf and destroy dead cells and pathogens and present pieces of those pathogens or 'antigens' to white blood cells called T and B lymphocytes. These cells then start to fight the infection or disease. A new type of antigen presenting cell will be investigated for its particular ability to arrest blood-borne pathogens and disease.
I am a Clinical Immunologist, Immunopathologist, clinical researcher and laboratory scientist exploring the interactions between T cell and viral infections. My area of particular interest is the mechanisms by which HIV infection subverts effective T cel

Summary
Autoimmune diseases constitute a significant medical problem in the developed world and are increasing in incidence. Many control mechanisms exist in the body, but in people with genetic suceptibility to autoimmune disease, the mechanisms fail and the body's immune sytem attacks normal tissues or organs. We have developed a new approach to using the cells which train the immune system to re-educate the cells that would otherwise attack normal healthy tissues in autoimmune-prone individuals.

Many control mechanisms exist in the body, but in people with genetic suceptibility to autoimmune disease, the mechanisms fail and the body's immune sytem attacks normal tissues or organs. We have developed a new approach to using the cells which train the immune system to re-educate the cells that would otherwise attack normal healthy tissues in autoimmune-prone individuals. These cells (dendritic cells) are genetically modified to express the molecular targets of the autoimmune response. This in turn switches off the response to these targets. In this project we will explore how these cells can be used to turn off cells of the immune system and if cells of the immune system in turn control the dendritic cell's ability to do this.Read moreRead less
This fellowship is to support Professor Stephen Kent in generating new advances in vaccines to prevent HIV (the cause of AIDS) and Influenza (“The Flu”). HIV causes over 1.5 million deaths per year and no vaccine is currently available. Influenza causes around half a million deaths per year. Although the current Influenza vaccine is partially effective, improvements are needed for it to be able to protect against the many different strains of Influenza that can cause infection.
Defining The Cellular Interactions For Initiation And Maintenance Of Immunity To Intracellular Pathogens

Summary
This immune system provides our body’s defense against invading organisms like viruses, preventing disease and maintaining health. Immunity involves the interaction of several different cell types that together form arsenals tailored to combat each different infection. Professor Heath will investigate how cells of the immune system orchestrate effective immune responses to viral infections and malaria. He will use this understanding to design novel approaches to vaccination.
