The aim of this project is to develop mathematical models and computer software capable of predicting immune responses to infection and disease. This “artificial immune system” should lead to improved vaccine design and better understanding of what causes the immune system to attack its own body, causing autoimmune disease, or fail to respond, causing immunodeficiency. This enabling science could then lead to improvements in treatment for a range of conditions of clinical importance.
Professor Godfrey is an immunologist with a long standing history as a pioneer in the study of a specialised type of white blood cell, known as NKT cells. NKT cells are activated in response to lipid-based molecules that are thought to alert the immune system, via NKT cell activation, to the presence of infectious agents or other abnormalities. A better understanding of how NKT cells function will provide new approaches to battling a broad range of diseases where these cells are implicated, incl ....Professor Godfrey is an immunologist with a long standing history as a pioneer in the study of a specialised type of white blood cell, known as NKT cells.

A better understanding of how NKT cells function will provide new approaches to battling a broad range of diseases where these cells are implicated, including cancer, autoimmunity, allergy and infection.Read moreRead less
Determining Regulators Of ILC3 In Mucosal Barrier Function And Immune Homeostasis

Summary
Innate lymphoid cells (ILCs) are specialized cells that defend the body against invading microorganisms at the body’s surfaces, mediate pathogen clearance and tissue repair but may also drive inflammatory conditions such as allergic asthma and inflammatory bowel disease. We will investigate the molecular switches that regulate this novel cell type and potentially uncover novel molecules or pathways for therapeutic targets.

Summary
The immune system can discriminate between invading microorganisms and the body's own tissues. Dendritic cells are specialised to alert the immune system in the case of infection. In this project we aim to understand how dendritic cells are generated and how they function to control the immune response. We will achieve this aim by using state of the art genomic technologies to describe the genetic programme of dendritic cells. We hope that this knowledge will enable us to better harness the immu ....The immune system can discriminate between invading microorganisms and the body's own tissues.

Summary
CD4 is a particular type of receptor on the surface of immune cells that participates in our response to infection. CD4 is also the primary receptor for the HIV virus which causes AIDS. We have discovered that a particular type of chemistry is occurring in CD4. This chemistry, which is known as redox chemistry, changes the shape of CD4. The shape change appears to be controlled by the immune cell. We have suggested that the redox chemistry in CD4 is important for controlling how immune cells res ....CD4 is a particular type of receptor on the surface of immune cells that participates in our response to infection. CD4 is also the primary receptor for the HIV virus which causes AIDS. We have discovered that a particular type of chemistry is occurring in CD4. This chemistry, which is known as redox chemistry, changes the shape of CD4. The shape change appears to be controlled by the immune cell. We have suggested that the redox chemistry in CD4 is important for controlling how immune cells respond to infection and how the HIV virus infects immune cells. Moreover, we have designed a small synthetic compound that blocks the redox chemistry in CD4 and prevents HIV infection in the test tube. We propose to investigate how the redox chemistry in CD4 controls the function of immune cells and infection by HIV.Read moreRead less
Immune Regulation During Uncomplicated And Severe P. Falciparum And P. Vivax Malaria

Summary
Malaria is a major global disease that kills over 1 million people every year. Immune responses induced during infection help fight the infection but can also cause tissue damage and thereby worsen disease. This study will determine differences in cellular immune responses during uncomplicated and severe malaria. Better understanding of the role of immune cells in response to infection and disease progression will assist the development of novel treatment interventions and vaccine development.
The Role Of Cytokines In Tumor-induced Immunosuppression

Summary
Cancer-induced immune suppression is a major obstacle to the effective treatment of many cancers. We have shown that the cytokine IL-23, plays an important role in cancer initiation, growth and development. My project aims to characterize the cells that produce IL-23 in the cancer microenvironment and define how it suppresses cells of the immune system. A greater understanding of this cytokine’s mechanism of action will enable the rational improvement of treatments for patients with cancer
Tolerance Induction By Antigen-presenting Cell-targeted Antigen

Summary
We have found that by ‘targeting’ antigen to the cells that ‘train’ the immune system we have been able to prevent the development of autoimmune disease. In the research proposed here we aim to develop new ways in which antigens can be targeted to these cells so that this approach can be applied clinically. The proposed studies will also determine how antigens targeted in this way restore self-tolerance and prevent autoimmune disease.
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
Chronic infectious diseases such as HIV/AIDS, tuberculosis, malaria and leishmaniasis are responsible for significant morbidity and mortality. They are all characterised by severe immune dysfunction. We will study a parasitic infection to identify important immune cell populations and molecules that promote chronic infectious disease. This knowledge will enable the development of better treatments and vaccines for range of infectious diseases that affect people in many parts of the world.
