Next, we adoptively transferred CD44+CD62L+GFI1hi, CD44+Ly108+GFI1hi or CD44+GFI1lo CD8+ T cells isolated from spleen and mLN of LCMVArm-infected mice at day 21 after infection into congenically marked secondary recipient mice that were subsequently infected with LCMVArm the next day. Here, CD44 is linked to infection.
