CD274 and neoplasm: In a separate study, Le et al. demonstrated that coating the surface of nanoparticles containing imiquimod and photosensitizer with anti‐PD‐L1 antibody can significantly increase nanoparticle accumulation in tumors overexpressing PD‐L1.[29] They represented a sequence of transmission electron microscopy (TEM) images that demonstrated the presence of nanoparticles on tumor cell surface sensitizes tumor cells to irradiation‐induced ICD and generates antitumor immunity (Figure 1B).
