Supplementary Figure 1: Phenotyping and in vivo proliferative responses of mature LLO56 and LLO118 T cells.

(a) In vivo proliferation of CFSE-labeled LLO56 and LLO118 T cells in response to Listeria at 2, 4, and 6 days post-infection. The presented FACS plots are representative of 6-7 mice analyzed over four experiments. (b) Expression of signaling and costimulatory molecules on LLO56 and LLO118 T cells. The distribution of CD5 expression for polyclonal B6 CD4+ T cells is included in the CD5 histogram for reference. Data are representative of at least three mice from at least three experiments.
