Therefore, the deletion of Zeb1 in DC resulted in a decrease in both the number and effector function of CD8+ T cells in tumors (Fig. 3g–j), which was unlikely due to regulatory T (Treg) cells, as the numbers of tumor-infiltrating Treg cells in WT and Zeb1-dcKO mice were comparable (Supplementary Fig. 4e, f). The gene discussed is ZEB1; the disease is neoplasm.
