There was a higher percentage of GZMB producing CD8+ T cells and higher expression of KLRG1 which is upregulated in highly cytotoxic effector CD8+ T cells [28] in the tumor draining lymph node (LN) harvested from 5-NL treated mice at day 13 post tumor inoculation (Fig. 2E). Here, KLRG1 is linked to neoplasm.
