CD8A and neoplasm: Tumor-bearing mice acquired a stronger expansion of CD3+CD8+CD44hiCD62L+ memory cells (median: control, 25%; Eμ-Tcl1Ebag9+/+, 59.4%) (Figure 1J) and a substantial loss of naive CD3+CD8+CD44loCD62L+ T cells (median: control, 58.8%; Eμ-Tcl1Ebag9+/+, 0.3%) (Figure 1G and Supplemental Figure 1B).
