In contrast, significant amounts of both IFN-γ and granzyme B were produced in co-cultures with MR1*01/*04 heterozygous donor-derived B cells and monocytes, suggesting that 7G5 TCR-T recognizes a ligand(s) that is present both in tumor cells and normal cells expressing MR1*04 (Figure 6B), similar to that observed in Lepore et al. This evidence concerns the gene GZMB and neoplasm.
