Anti-PD-L1 (intraperitoneally (i.p.), days 7, 10, 13 and 16) was given either to mice whose tumour cells (B16F10-mCherry-OVA, i.d., 5 × 105 cells) were inoculated on the same day, or to mice with established tumours (around 85 mm3; achieved by inoculating Trpv1cre::DTAfl/WT around 3 days before). This evidence concerns the gene CD274 and neoplasm.
