An investigation into the basis of the T-cell mediated adaptive immune response. Understanding the adaptive immune response to human pathogens is critically important to develop strategies to combat infection. This project will provide a better understanding of how T cells combat viral infection, and will lead to fundamental advances in our understanding of viral immunity and the development of novel immunotherapeutic strategies.
A molecular and functional investigation of innate-like T cells of the immune system. This project will investigate innate-like T cells, which are at a crossroad between innate and adaptive immunity. A complete knowledge of the cellular function and balance of these cells will offer potential for new immunotherapies associated with infectious and autoimmune disorders.
Drivers of effective T cell immunity. This project aims to investigate the mechanisms underpinning an effective immune response. In doing so, the project expects to decipher the various determinants of T cell immunity and explore how these determinants are integrated to generate effective immunity. The project will use a multidisciplinary approach to investigate antigen abundance and developmental, structural, and molecular aspects of T cells, expecting to significantly enhance our fundamental u ....Drivers of effective T cell immunity.

Understanding T cell immunity induced by infection. We aim to understand how killer T cells are “programmed” upon activation and acquire their characteristic functions and how these are maintained into immunological memory. This proposal will provide insights important for the design and improvement of vaccine strategies to fight pathogens such as influenza, HIV and even tumors.
The regulation of anti-viral immunity by host and viral proteins. Anti-viral immunity is initially triggered when specific immune sensors detect viral components within the cell. This project will use a combined functional/structural approach to investigate the specifics of immune activation by a pivotal immune sensor and use this information to understand how influenza A sabotages this specific immune response.
How the immune system recognises vitamin B-based allergies. This project aims to evaluate the range of molecules that can stimulate vitamin B-reactive T cells in mammals and amphibians, and the degree of conservation or variation in these molecules among diverse microorganisms. T cells are immune cells that recognise foreign molecules, including peptides, lipids and vitamin B metabolites, bound to specialised antigen-presenting molecules. In mammals, Mucosal Associated Invariant T cells, still p ....How the immune system recognises vitamin B-based allergies. This project aims to evaluate the range of molecules that can stimulate vitamin B-reactive T cells in mammals and amphibians, and the degree of conservation or variation in these molecules among diverse microorganisms. T cells are immune cells that recognise foreign molecules, including peptides, lipids and vitamin B metabolites, bound to specialised antigen-presenting molecules. In mammals, Mucosal Associated Invariant T cells, still poorly understood, recognise Vitamin B-based molecules. Combining immunology with structural biology and chemistry, this project aims to understand how the immune system detects molecules produced by diverse microorganisms.Read moreRead less
Recognition of lipid antigens by the immune system. T cells are a critical component of the immune system, protecting against a range of pathogens by detecting and responding to foreign molecules. Despite their importance, there is still much to learn about how T cells function. New types of T cells that respond to bacteria-derived lipid molecules, have recently been identified. This project aims to undertake a molecular and functional investigation into lipid-reactive T cells. This will provide ....Recognition of lipid antigens by the immune system.

Despite their importance, there is still much to learn about how T cells function. New types of T cells that respond to bacteria-derived lipid molecules, have recently been identified.

This will provide basic fundamental insight into a poorly understood, but crucial, component of the immune system as well as an opportunity to ultimately develop novel lipid-based vaccines.Read moreRead less
Defining the molecular architecture of a lymphocyte-activating receptor complex. A robust immune response requires activation of sentinel T cells. This project will seek to understand the architecture of receptors at the T cell surface that allow these important immune cells to sense the presence of pathogens that react accordingly.
Metabolite- and lipid-based immunity. This project aims to investigate T-cell immunity to lipids and metabolites. The immune system protects hosts from pathogens, and uses T-cells to recognise infected host cells. However, many facets of T-cell function are not understood. This project will unearth the evolutionary and molecular correlates of lipid- and metabolite-based immunity across diverse species. This will provide basic fundamental insights and conceptual advances into a poorly understood, ....Metabolite- and lipid-based immunity.

T cell recognition and control of virus: the balance between T cell receptor diversity and degeneracy. T cells provide an important line of defence in the immune system's resistance against infectious diseases. However, changes to the T cell population during prolonged infection, and with age, can compromise the immune system's ability to fight effectively viral infections. The proposed research will greatly improve our understanding of the recognition and control of viral infections by T cells. ....T cell recognition and control of virus: the balance between T cell receptor diversity and degeneracy.

The proposed research will greatly improve our understanding of the recognition and control of viral infections by T cells.
