Inflammation and PD-L1 expression in pulmonary neuroendocrine tumors

Prognostic value of PD-L1 and PD-1 expression in pulmonary neuroendocrine tumors

PURPOSE Programmed death 1 (PD-1) receptor and its ligand, programmed death ligand-1 (PD-L1), play critical roles in the immune invasion of various tumors. This study aimed to explore the clinical significance of PD-L1/PD-1 expression in the progression of pulmonary neuroendocrine tumors (PNETs). METHODS The expression of PD-L1 and PD-1 in 80 patients diagnosed with PNETs were investigated. I...

Over-Expression of Immunosuppressive Molecules, PD-L1 and PD-L2, in Ulcerative Colitis Patients

PD-L1, Inflammation and Glioblastoma

The PD-L1 protein has an extracellular domain, a transmembrane domain and an intracellular domain. The extracellular domain (ECD) of the PD-L1 protein is comprised of IgC–like and IgV-like domains [2]. The ECD of PD-L1 interacts with the programmed death 1 (PD-1, also known as PDCD1) and B7.1 receptors. Blocking of the PD-L1 molecule with antibodies blocks cancer cells from killing cytotoxic T ...

Immunohistochemical Expression of Pd-l1 in Solid Tumors

Recent clinical trials have demonstrated that it is possible to induce durable remission in several tumors (non-small cell lung cancer (NSCLC), melanoma, squamous cancer of head and neck, renal cell carcinoma, Hodgkin lymphoma, colorectal cancer) by blocking the PD-1/PD-L1 (programmed death-1/programmed death-ligand 1) axis with anti-PD-1 or antiPD-L1 antibodies and that an objective clinical r...

Thymidylate synthase expression in gastroenteropancreatic and pulmonary neuroendocrine tumors.

PURPOSE The predictive role of the quantification of thymidylate synthase (TS) in tumors treated with antifolate drugs, such as 5-fluorouracil (5-FU), has been extensively reported in a variety of human tumors. Neuroendocrine tumors (NET) represent potential targets of antifolate agents, but no data on TS expression level in these tumors are currently available. EXPERIMENTAL DESIGN A series o...
