CD8A and neoplasm: The number of tumor-infiltrating lymphocytes, CD3+, CD4+, CD8+, and CD8+ activated and effector T cells was also correlated with tumor size (Figures 4B–4D) with a significantly higher number of these cell populations per mg tumor in the tumors from mice treated with the Sulanemadlin + anti-PD-1 treatment combination (Figure 4D).
