Cuproptosis and Disulfidptosis Converge to Empower PD‐L1 Checkpoint Therapy via Cadict‐Induced PD‐L1 Translation [PDF]

Advanced Science
Immune checkpoint blockade (ICB) has emerged as a cornerstone of cancer therapy, yet its effectiveness remains restricted in PD‐L1‐low malignancies due to insufficient target expression.

PD-L1: expression regulation

Blood Science, 2023
Programmed death-ligand 1 (PD-L1), expressed on the surface of tumor cells, can bind to programmed cell death-1 (PD-1) on T cells. The interaction of PD-1 and PD-L1 can inhibit T-cell responses by decreasing T-cell activity and accelerating their ...

Extracellular vesicles mediate intercellular transfer of PD-L1 and bystander T-cell suppression [PDF]

Cellular and Molecular Life Sciences
Extracellular vesicles (EVs) carrying programmed death-ligand 1(PD-L1) on their membranes regulate immune responses. While membrane PD-L1 can be exchanged between tumor and immune cells through immune synapse, it remains unclear whether PD-L1 exchange ...

PD-L1 [PDF]

Journal of Clinical Pathology, 2017
Programmed death ligand 1 (PD-L1) is the principal ligand of programmed death 1 (PD-1), a coinhibitory receptor that can be constitutively expressed or induced in myeloid, lymphoid, normal epithelial cells and in cancer. Under physiological conditions, the PD-1/PD-L1 interaction is essential in the development of immune tolerance preventing excessive ...

Further investigation of blockade effects and binding affinities of selected natural compounds to immune checkpoint PD-1/PD-L1

Frontiers in Oncology, 2022
The breakthrough in the discovery of immune checkpoint PD-1/PD-L1 inhibitors, such as the series of Bristol Myers Squibb synthetic compounds, boosted the research of small molecules with blockade effects on the interaction of PD-1/PD-L1.

PD-L1 Amino Acid Position 88 Represents a Hotspot for PD-L1 Stability With Relevance for PD-L1 Inhibition

Frontiers in Oncology, 2022
The two most common antibody targeting principles in oncology are the induction of direct antitumor effects and the release of antitumor T cell immunity by immune checkpoint blockade. These two principles, however, may be overlapping if the targeted checkpoint molecule is not located on the immune cell but on the tumor cell itself. Secondary resistance

Programmed Cell Death Ligand 1 Is Enriched in Mammary Stem Cells and Promotes Mammary Development and Regeneration

Frontiers in Cell and Developmental Biology, 2021
Programmed cell death ligand 1 (PD-L1) is widely expressed in a variety of human tumors, and inhibition of the PD-L1/PD-1 pathway represents one of the most promising therapy for many types of cancer.

PD-L1 and PD-L2 Expression in Cervical Cancer: Regulation and Biomarker Potential

Frontiers in Immunology, 2020
PD-1/PD-L1 immune checkpoint inhibitors show potential for cervical cancer treatment. However, low response rates suggest that patient selection based on PD-L1 protein expression is not optimal.

Programmed Cell Death Ligand 1 Expression in Circulating Tumor Cells as a Predictor of Treatment Response in Patients with Urothelial Carcinoma

Biology, 2021
Programmed cell death ligand 1 (PD-L1) inhibitors are commonly used in treating advanced-stage urothelial carcinoma (UC). Therefore, this study evaluated the relationship between PD-L1 expression in circulating tumor cells (CTCs) and treatment response ...

Small-molecule PD-L1 inhibitor BMS1166 abrogates the function of PD-L1 by blocking its ER export

OncoImmunology, 2020
Therapeutic monoclonal antibodies against the PD-L1/PD-1 (programmed death ligand-1/programmed cell death protein-1) axis have achieved great successes in cancer treatments, but the development of small-molecule immunomodulators of the pathway has lagged
