CD8A and neoplasm: Regarding the effector cells (CD8+ cells) in the slides, the number of effector cells in the tumor was not significantly different compared to the control group (number of CD8 T cells in the tumor areas (mm2): control mice = 0.46 ± 0.42/mm2, GO-Y022-treated mice = 0.40 ± 0.27/mm2, p-value = 0.8472) (Figures 5C, D).
