Indeed, complementation with WT LY9 via lentiviral transduction, unlike empty vector (EV), was sufficient to promote IFN-γ secretion induced by THP-1 plus HKMTb plus CytoStim in LY9-deficient CD4+ T-blasts or LY9 KO HuT78 T-lymphoma cells (Fig. 4G). This evidence concerns the gene IFNG and lymphoma.
