CD8A and neoplasm: Flow cytometry analysis of resected 4T1 tumors collected from a separate experiment showed that the combination treatment resulted in increased expression of IFNγ, TNFα, and granzyme B in intratumoral CD8+ T and NK cells (Fig. 6f and Fig. S9f), as well as an overall increase in tumor-infiltrating CD8+ T cells (Fig. 6f).
