Data comparing the ratio of proliferation of KdM282–90-specific cells/proliferation of DbM187–195-specific cells induced by CD103+ DCs sorted from neonates or adults 1 day post-infection from four independent experiments showed a significant difference in epitope-specific proliferation by neonatal and adult DCs (p = 0.0005, Figure 5B). This evidence concerns the gene ITGAE and infection.
