Increased secretion of interferon γ (IFN‐γ), interleukin (IL)‐2, and tumor necrosis factor α (TNF‐α) was measured in B7H3‐redirected BiTE‐T cells cocultured with B7H3‐positive tumor cells (A375, MV411, SKOV3, and THP‐1) (Figure S4B–D, Supporting Information). This evidence concerns the gene TNF and neoplasm.
