CD1C-LIPID-REACTIVE T CELLS. The immune system patrols our body examining molecules such as proteins and lipids that signal whether or not everything is ok. While protein recognition by the immune system is well understood, our knowledge of the fundamental features of lipid detection is poor. This project will investigate the detection of lipid molecules that are presented to the immune system in association with a molecule known as CD1c. The aims are to understand: 1.

While protein recognition by the immune system is well understood, our knowledge of the fundamental features of lipid detection is poor. This project will investigate the detection of lipid molecules that are presented to the immune system in association with a molecule known as CD1c. The aims are to understand: 1. The cells that respond to these lipids; 2. The cellular receptors that bind to these lipids; 3. The types of lipids involved in this process. This work is essential for us to understand lipid-based immunology which is critical if we ultimately wish to harness this to improve human health.Read moreRead less
Antigen selection mechanisms control T cell immunity against bacteria. CD4+ T (T helper) cells are required to control many important bacterial infections. This Project aims to identify the key targets of CD4+ T cells responding to a model bacterial infection, and to correlate potential antigen effectiveness with native expression, antigen presentation, and the function of antigen-specific CD4+ T cells over time. Our validated experimental 'pipeline' has unprecedented potential to define potent ....Antigen selection mechanisms control T cell immunity against bacteria. CD4+ T (T helper) cells are required to control many important bacterial infections. This Project aims to identify the key targets of CD4+ T cells responding to a model bacterial infection, and to correlate potential antigen effectiveness with native expression, antigen presentation, and the function of antigen-specific CD4+ T cells over time. Our validated experimental 'pipeline' has unprecedented potential to define potent CD4+ T cell antigens within the thousands of proteins expressed by a bacterial pathogen. Our unbiased analysis may help establish the rules that define effective antigenicity. Our work will improve the understanding of bacterial immunity, and inform future design of T-cell based vaccines in the agricultural sector.Read moreRead less
Deciphering novel cross-talk between innate cytokine receptors. Understanding the basic functions of interferons, how they signal to cells, is central to understanding fundamental immunity. Interferons are crucial molecules of the immune system that are important for normal cell development and they protect the body from viral infection and cancer but can be deleterious in different autoimmune diseases and trauma settings. Preliminary Data shows there is a pathway of interferon signalling that h ....Deciphering novel cross-talk between innate cytokine receptors. Understanding the basic functions of interferons, how they signal to cells, is central to understanding fundamental immunity. Interferons are crucial molecules of the immune system that are important for normal cell development and they protect the body from viral infection and cancer but can be deleterious in different autoimmune diseases and trauma settings. Preliminary Data shows there is a pathway of interferon signalling that has previously been overlooked. This project aims to understand how this pathway works and how it contributes to the normal workings of cells. This fundamental science has future consequences for the design of vaccines and for the design of therapeutics to treat diseases that show defective interferon signalling.Read moreRead less

Engineering T cells to promote peripheral immunity. Tissue-resident memory T cells (TRM) are key for immune protection against infections and cancer. This has led to much interest in understanding how these immune cells develop, although elucidation of molecules that regulate TRM are still scarce. This project aims to (i) identify genetic drivers of TRM in peripheral organs and (ii) modulate TRM generation utilising state-of-the-art genetic engineering techniques. Expected outcomes include gener ....Engineering T cells to promote peripheral immunity. Tissue-resident memory T cells (TRM) are key for immune protection against infections and cancer.
