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
