Anti-PD-L1
Anti-PD-L1 agents are monoclonal antibodies that block CD274 molecule from engaging its receptor Programmed cell death 1 (PD-1), and from engaging B7-1 (CD80).
Anti-PD-L1 agents are monoclonal antibodies that block CD274 molecule from engaging its receptor Programmed cell death 1 (PD-1), and from engaging B7-1 (CD80). Tumors and myeloid cells in the tumor microenvironment exploit that ligation to switch off cytotoxic T cells; blocking it restores their activation, proliferation, and killing. Approved agents include atezolizumab, durvalumab, and avelumab. They are used in non-small cell lung cancer, small cell lung cancer, urothelial and bladder cancer, hepatocellular and biliary tract cancer, and Merkel cell carcinoma, typically combined with chemotherapy or, in hepatocellular carcinoma, with antiangiogenic therapy.
Blocking the ligand rather than the receptor is the pair's practical difference: melanoma, where the class is not a standard option, is treated with anti-PD-1 and anti-CTLA-4 agents instead. PD-L1 expression by immunohistochemistry, scored as tumor proportion score or combined positive score, is the routine companion biomarker, but it predicts response imperfectly — expression is dynamic, focal, and driven by interferon signaling — so tumor mutational burden and mismatch repair status are used alongside it. Most patients still do not respond, which is why current work pairs PD-L1 blockade with a second, mechanistically distinct intervention.

Tumor Immune Microenvironment
Immune-suppressive tumor microenvironments are being reprogrammed to improve anti-PD-L1 responses across cancers. Approaches target PD-L1 turnover with ethoxzolamide or selenium inhibitors, while USP5-FOXM1-Nectin2 signaling marks resistance. Other studies alter myeloid inflammation, T-cell niches, adenosine and cuproptosis, or use vaccines and bacteria. The direction is combination immunotherapy, although the varied models leave the most transferable strategy unresolved.

Triple-Negative Breast Cancer Immunotherapy
Triple-negative breast cancer immunotherapy is moving toward multimodal combinations that pair checkpoint targeting with chemotherapy, photodynamic therapy, virotherapy or metabolic intervention. Cabazitaxel-verteporfin nanoparticles and engineered probiotics seek to intensify tumor killing alongside immune activation. Oncolytic adenovirus targeting Siglec-10, hypoxia-lactate-calcium coupling and PD-L1/VEGF bispecific blockade extend this strategy. Peripheral immune dynamics may help distinguish effective chemoimmunotherapy from nonresponse.

Colorectal Cancer Immunotherapy
Colorectal cancer studies are shifting checkpoint blockade toward combinations that alter tumor metabolism, mechanics, microbiota and protein trafficking. Gemcitabine enhances anti-PD-L1 sensitivity through lactylation, while Faecalibacterium prausnitzii reprograms PD-L1 trafficking. Biomimetic nanodecoys address the mechano-immune microenvironment, and engineered bacteria combine tumor-targeted protein degradation with checkpoint inhibition. These preclinical sensitization strategies still require evidence for durability and clinical translation.

Oral Cancer Immune Signaling
CIP2A silencing is being paired with PD-1 macrophage nanoplatforms to activate immunity in oral squamous cell carcinoma. The same disease context includes PD-L1 profiling in potentially malignant disorders and tumor-free surgical margins. TCGA-linked analyses may clarify whether CIP2A and PD-L1 mark progression risk. The work is moving from biomarker description toward targeted immune remodeling, but clinical relevance remains open.

Anti-PD-L1 serves as a tumor-targeting and drug-delivery interface, not only as an immune checkpoint blocker
The adamantane-conjugated anti-PD-L1 pretargeting lipid-nanoparticle system 42839730Oct and the defactinib-loaded, PD-L1-antibody-conjugated platelet-membrane nanodecoy for colorectal cancer 42002768Apr both use anti-PD-L1 to localize therapeutic cargo within tumors, in addition to or alongside checkpoint blockade. The set otherwise treats anti-PD-L1 chiefly as an agent whose benefit comes from releasing T-cell inhibition. These studies instead show that PD-L1 binding can function as a physical targeting and retention mechanism that concentrates nanoparticles or membrane-coated payloads in the tumor, expanding anti-PD-L1 from an immune effector into a delivery architecture.
