In May 2020, the atezolizumab was approved by the FDA for the first-line treatment of adults with metastatic non-small cell lung cancer (NSCLC) whose tumors have high PD-L1 expression (PD-L1 stained ≥ 50% of tumor cells [TC ≥ 50%] or PD-L1 stained tumor-infiltrating immune cells [IC] covering ≥ 10% of the tumor area [IC ≥ 10%]), with no ...
PD-L1 binds to its receptor, PD-1, found on activated T cells, B cells, and myeloid cells, to modulate activation or inhibition. The affinity between PD-L1 and PD-1, as defined by the dissociation constant K d, is 770 nM. PD-L1 also has an appreciable affinity for the costimulatory molecule CD80 (B7-1), but not CD86 (B7-2).

Ventana Medical Systems, Inc. was a medical device company that develops, manufactures, and markets instrument reagent systems that automate tissue and slide staining in anatomic pathology laboratories. These products assist in the diagnosis and treatment of cancer and infectious diseases.
At least two PD-L1 inhibitors are in the experimental phase of development. KN035 is the only PD-L1 antibody with subcutaneous formulation currently under clinical evaluations in the US, China, and Japan [35] Cosibelimab (CK-301) by Checkpoint Therapeutics is a PD-L1 inhibitor developed by Dana Farber, and is currently in Phase 3 trials for ...
Non-small cell lung cancer (NSCLC) cells expressing programmed death-ligand 1 (PD-L1) could interact with programmed death receptor 1 (PD-1) expressed on the surface of T cells, and result in decreased tumor cell kill by the immune system. Atezolizumab is an anti PD-L1 monoclonal antibody.
In today's puzzle, there are eight theme words to find (including the spangram). Hint: The first one can be found in the top-half of the board. Here are the first two letters for each word:
Micrograph showing a PD-L1 positive non-small cell lung carcinoma. PD-L1 immunostain. As of 2019, pembrolizumab is used via intravenous infusion to treat inoperable or metastatic melanoma, metastatic non-small cell lung cancer (NSCLC) in certain situations, as a first-line treatment for metastatic bladder cancer in patients who cannot receive cisplatin-based chemotherapy and have high levels ...
The setting of reasonable cutoff limits help reduce false positive results that occur from assay limitations. Because of the social and legal consequences, a positive test result must be confirmed by an alternative method, usually Gas Chromatography/Mass spectrometry.
