PDCD1LG2 and neoplasm: To this aim, we treated mice bearing EG.7-OVA tumors with a single dose of CTX (100 mg/kg) followed by a peritumoral injection of anti-PDL1 and anti-PDL2 Abs to block intratumoral PDLs, given three days later (Figure 4A), i.e., at the time of maximum myeloid infiltration into the tumor (Figure 2D).
