After adoptive transfer of CD4+ T cells, the CD44+CD62L‒CD8+ T cells of the rEg.P29+Infection group were decreased compared with those of the PBS+Infection group and CpG+Infection group, while the proportions of CD44‒CD62L+CD8+ T cells were not significantly different (Figure 6D‒F). This evidence concerns the gene CD44 and infection.
