When we assessed tumors and the tumor-draining lymph node from 5-NL and vehicle treated mice at day 20 post tumor inoculation, we observed higher cytotoxic CD8+ T cell effector activity (higher percentage and expression of GZMB producing CD8+ T cells) in the tumors of 5-NL treated mice (Fig. 2E). This evidence concerns the gene CD8A and neoplasm.
