Summary
Malaria claims nearly one million lives each year, mostly children. Although those living in endemic regions can acquire natural immunity, it develops slowly and isn`t completely protective. This project studies the impact of different levels of malaria exposure and age on the development of a protective immune response in children. By understanding the effect of high malaria exposure in the development of immunity it is hoped that new avenues for drug development may be identified.
Protective memory T cell immune responses defend our body against pathogens by the rapid induction of killer T cells. This protects us from severe or perhaps even fatal disease. Our work will provide insights to how the body makes these potent ‘footsoldiers’. This work will have important implications for identifying how these immune cells can be manipulated to prevent and treat pathogenic and autoimmune disease and for optimising approaches to vaccination.
Transcriptional Regulation Of Specialized Subsets Of Dendritic Cells In Control Of Infection

Summary
Immune protection against viruses and bacteria depends on specialized cells called dendritic cells that display components of the invading organisms on their surface. There are multiple different types of dendritic cell and each population plays a specialized role in defending the body against infection. Our work will provide the framework for directly targeting these cells for novel vaccines to re-program the immune system for clinical conditions such as cancer, allergy and autoimmunity.

Summary
Herpesviruses are a major cause of disease worldwide and are amongst the most successful human pathogens, with some viruses infecting more than 80% of the world's population. This group of viruses persist and reactivate in hosts and induce immunosuppression.The control of herpesviruses infections thus represents an important clinical goal. Understanding the mechanisms involved in the induction of viral persistence and immunosuppression is a crucial step towards developing better therapies.
Transcriptional Regulation Of T Cell Memory Programming

Summary
Differentiation of T cells is required to protect against disease. A group of proteins, called transcription factors, critically regulate this fundamental process, during which T cells become effector cells (that can kill pathogen infected cells) or memory cells (that are essential for protection against secondary infections). To identify the functions and hierarchy of these regulators is critical to therapeutic treatment of autoimmune and infectious disease and is the aim of this application.
Transcriptional Regulation Of T Lymphocyte And Dendritic Cell Development

Summary
Differentation of lymphocytes is a fundamental process in protection against disease . A small number of proteins critically regulate the decisions the cells make in becoming effective antigen presenting cells (that stimulate other immune cells), effector cells (that kill pathogen infected cells) or memory cells (that are essential for protection against secondary infections). Understanding this process and its regulation is critical to therapeutic treatment of autoimmune and infectious disease.

The intestine is the largest surface area forming a protective barrier between the external environment and the body. It represents the first line of defence against invading pathogens. The immune system of the intestine is critical to protect this tissue -any breakdown leads to profound and progressive inflammatory disease of the gut such as chronic inflammatory bowel disease.
