Defining pathways that control T cell lifespan for long-term immunity. This project will investigate the cellular and molecular pathways regulating lifespan of tissue-resident memory T cells (Trm cells), a non-circulating T cell subset that play a crucial role in the frontline defence against infection. Significantly, how long Trm cells live is paramount to how long immunity is sustained.

This project will investigate the cellular and molecular pathways regulating lifespan of tissue-resident memory T cells (Trm cells), a non-circulating T cell subset that play a crucial role in the frontline defence against infection. Significantly, how long Trm cells live is paramount to how long immunity is sustained. Using cutting-edge cellular and molecular techniques, the expected outcomes of this project include identification of the genes and processes that control lifespan. This should provide significant benefits in the basic knowledge of how longevity of immunity is regulated. This understanding will be useful for future immunotherapeutic applications, such as veterinary or human vaccines requiring maximal duration of immunityRead 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
