Moreover, IFN-γ levels positively correlated to mAb 14-25-9 staining levels on MM target cells with a 4.8-fold increase in IFN-γ level in media sampled from pNK cells incubation with Pat#2 target cells (91.7%, gated from CD38+CD138+ cells, positive for mAb 14-25-9 staining) versus a 2.6-fold increase in media sampled from pNK cells incubation with Pat#7 target cells (30.4%, gated from CD38+CD138+ cells, positive for mAb 14-25-9 staining) (Figure 5B,C). This evidence concerns the gene IFNG and Miyoshi myopathy.
