To determine if the binding of PDL1-scFv-Fc-RE7 with the ID8 luciferase-expressing tumor cells can render the tumor cell susceptible to E7-specific CD8+ T cell-mediated killing, the percentages of viable ID8-luc were measured by luciferase activity after incubating the cells with E7-specific CD8+ T cells. The gene discussed is CD274; the disease is neoplasm.
