Two doses of chemotherapy (day+6) in AB1-HA tumor bearing animals significantly increased the frequency of tumor-infiltrating CD8+ TPEX from 25.3±17.3% in PBS-treated animals to 82.6±11.1% (p≤0.0001) and 87.6±6.95% (p≤0.0001) in 5FU and GEM-treated animals, respectively (figure 1E,F). Here, CD8A is linked to neoplasm.
