CD103+ DCs were sorted out of the MLN of mice one day after infection at 7 days old or as an adult, and co-cultured in a 1∶10 ratio with CFSE-labeled KdM282–90 or DbM187–195-specific T cells isolated from adult TCR Tg mice without the addition of any exogenous peptide (Figure 5). This evidence concerns the gene ITGAE and infection.
