CD274 and colorectal cancer: The core of this nanomaterial was obtained via phosphorylation of Zn2+ ions and OXL, then capped with a monolayer of 1,2-dioleoyl-sn-glycero-3-phosphate (DOPA) molecules, while the shell was mainly made of pyrolipid with a photosensitizer ability (NCP@pyrolipid), and it was employed to deliver chemotherapy and PDT to colorectal cancer in combination with anti-PD-L1 checkpoint inhibitors [114].
