CD8A and neoplasm: To correlate tumor growth inhibition with antigen specific anti-tumor CD8 T cell activity, we immunized animals with CpG + o/w emulsion, to rule out formulation specific anti-tumor activity, or with SLP + CpG + o/w emulsion and tracked the appearance of E7 dextramer positive CD8 T cells in C57BL/6 mice implanted with TC-1.
