Figure 5. ABabDR4-derived TCR-3598_2 showed no alloreactivity.
TCR-transduced CD4+ T cells were cocultured with a panel of LCLs expressing different MHC class I and II molecules (Supplemental Table 1). As a positive control, PMA and ionomycin were added to the T cells. After overnight incubation, IL-2 was measured in the supernatant. Background, defined as the highest cytokine secretion observed for untransduced T cells, is indicated by the dotted line. Mean values of intra-assay duplicates with SD are shown. In the grid below, cross-reactions to LCLs are marked by an X. The results are representative of 3 independent experiments performed with PBLs from different donors. See also Supplemental Figure 3.
