When OT-1@SrtA cells were co-incubated with B16-OVA-G5 cells transfected with different plasmids, the percentage of LPETG-positive tumor cells in PLIGHT group were almost unchanged but increased about 3-fold in both PαCD3 and PαCD3&LIGHT groups relative to the Blank and PCtrl groups, again demonstrating the αCD3 promoted cellular interaction (Figure 4L). Here, TNFSF14 is linked to neoplasm.
