Outline of Final Research Achievements |
Immune checkpoint inhibitors targeting PD-L1 and PD-1 often show synergistic effects on NSCLCs. To elucidate the role of EGFR-mediated signal on lung tumor immunology, LLC cells were examined for the immune modulator expression. Although LAG-3 and B7-H3 expression was negative, a fair amount of PD-L1 was detected. We then established PD-L1 knockout cells and implanted into syngeneic mice, but TIL infiltration was relatively low. To increase TIL infiltration we introduced CTIIA, and succeeded in MHC up-regulation.
