WebFeb 22, 2024 · By using bispecific T-cell engager technology to assess the cytotoxicity of T cells, we found that the cytotoxicity of tumor-infiltrated T cells closely correlated with that of peripheral T cells. WebCytotoxic T cells can be cultured with activating antibodies such as anti-CD3 and tested for their ability to kill tumor targets in an IncuCyte-based assay. The ability of novel therapeutics to potentiate cytotoxic T cell killing can then be assessed by quantifying the change in the number of viable tumor cells over time.
