My research is aiming to study how the immune system controls viral infections in transplant patients and use this information to bolster their immunity in a test tube, providing protection against a virus the patient is unable to fight after their transplant. We are also trying to develop new strategies to use patient's own blood cells which will be grown in the laboratory and returned to the patient, resulting in a full recovery.
Follicular Cytotoxic T Cell Differentiation And Function In Infection And B-cell Lymphoma

Summary
Cytotoxic T cells eliminate infected or cancerous cells, constituting a major arm of the immune defence. In this study, we will investigate a subset of cytotoxic T cells that particularly migrate into B cell follicles to control infection and malignancy. Understanding of the differentiation and function of this subset, termed as follicular cytotoxic T (TFC) cells, will help us to develop new strategies to treat EBV and HIV infections as well as B cell lymphomas.

Summary
EBV is ubiquitous virus that infects more than 90% of the population worldwide. Although infection is largely asymptomatic in most healthy individuals, EBV is nonetheless associated with the development of at least 7 distinct types of human malignancies. Most importantly, EBV is still a huge healthy problem in conditions of immune suppression. Therefore a better understanding of the mechanisms involved in effective control of the virus will help develop better immune therapies and vaccines.
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.

Summary
I am an immunologist focused on identifying how B lymphocytes, the cells responsible for producing antibodies, survive and participate in immune responses within the body. I achieve this by using specially designed, genetically modified, mice that allow me to follow B lymphocytes within the body and identify their key genetic and external controls. My work is relevant to vaccine development as well as the control of certain autoimmune diseases and B lymphocyte cancers.
Regulation Of T Cell Effector Function In Peripheral Tissues

Summary
Protection from infections relies on different types of immune cells. While some of these cells are found in the blood, others reside in peripheral tissues such as the skin. We will analyse the function of these peripheral immune cells to understand how they work to fight off infections. We will also investigate how so-called memory cells that permanently reside in peripheral tissues can protect from re-infection with similar bacteria or viruses.
The Molecular And Cellular Trajectories Of Clonal Dendritic Cell Development

Summary
Dendritic cells (DCs) are a blood cell type with a crucial role in our immune system. They are made in the bone marrow from stem and progenitor cells. How each of these cells individually makes DCs is complex and dynamic. We seek to understand this using cutting edge technologies to track each cell’s step-by-step role in this important process. This knowledge may help the use of DCs in the treatment of several diseases including autoimmunity and cancer.
The Role Of CD1-restricted T Cells In Health And Disease

Summary
The human immune system requires T cells for survival. Specialised populations of T cells exist that patrol the body and target unwanted lipid molecules expressed by bacteria or by cells that have become abnormal or cancerous. I will identify these T cells in human blood and skin and determine their role in protection against disease. I will explore the types of lipids molecules recognised by these T cells and use this information to help prevent human diseases.

Summary
The aim of this proposal is to investigate immune cells called T follicular helper cells using a novel microscopy-based method that we have developed. This method lets us ‘tag’ these cells in a way that enables us to distinguish them from all other cells and follow them as they migrate to different immunological compartments during the response. T follicular helper cells are important for protective immune responses against pathogens and a better understanding of this T cell subset will aid vacc ....The aim of this proposal is to investigate immune cells called T follicular helper cells using a novel microscopy-based method that we have developed.
