Moreover, the analysis of memory response showed that anti-NKG2A decreased the amount of effector CD44+ KLRG1+ CD8 T cells and increased the proportion of central memory CD44+ CD62L+ CD8 T cells (Supplementary Figure S5C), suggesting that the effect of NKG2A is maintained in the long-term and it is not dependent from tumor presence. Here, KLRG1 is linked to neoplasm.
