Briefly, during the experiment, dCAR-T cells could release significant levels of cytokines only in the presence of cognate tumor cells expressing both CEA and MSLN, including 751 pg/mL IL-2, 9297 pg/mL IFNγ, 1777 pg/mL TNFα, 732 pg/mL IL-4, 8991 pg/mL IL-13, and 99 pg/mL IL-15. The gene discussed is IL15; the disease is neoplasm.
