Moreover, mice treated with T cells plus FasL and/or PD‐L2 blocking antibody‐treated TCN, also showed a decreased tumor growth with increased CD8+ T cell infiltration (Figure 7B; Figure S12B, Supporting Information), and increased IFN‐γ (Figure 7C; Figure S12C, Supporting Information), granzyme B (Figure 7D; Figure S12D, Supporting Information), and TNF‐α production (Figure 7E; Figure S12E, Supporting Information) in tumors or from spleen CD8+ T cells, compared with the mice treated with T cells plus TCN or control IgG‐treated TCN. The gene discussed is GZMB; the disease is neoplasm.
