When the primary tumours reached ∼100 mm3, mice were randomly divided into seven groups (n=6): (1) PBS with irradiation, NCP@pyrolipid (2) without or (3) with irradiation, NCP@pyrolipid plus anti-PD-L1 (4) without or (5) with irradiation, (6) porphysome with irradiation plus anti-PD-L1 and (7) oxaliplatin plus porphysome with irradiation plus anti-PD-L1. Here, CD274 is linked to neoplasm.
