Effect of CD134+CD4+ T cell killing on the phonotype of CD4+ T cells. (a) Naïve, (b) memory and (c) regulatory CD4+ T cell expression of FoxP3 and activation markers, and production of cytokines following in vitro re-stimulation. Numbers within the plots represent the percentage of CD4+ T cells that were positive for each marker. Plots are representative of 4-7 mice per group.
