CD8A and neoplasm: Immunohistochemistry evaluation revealed an increase of CD8+ T cells in tumor specimens compared to vehicle after treatment with DAC alone, with the greatest T cell recruitment after the combination of DAC and 4H2 (P = .0456 and 0.0006, respectively), however, we did not see a statistically significant change in F4/80+ murine macrophages in the flank tumors following any treatment (P = .9058 Veh vs DAC and 0.9510 Veh vs DAC + 4H2) (Supplementary Figure S9C and SD).
