Regulation of PD-1/PD-L1 pathway and resistance to PD-1/PD-L1 blockade

Oncotarget, 2017
Immune checkpoint blockades, such as inhibitors against programmed death 1 (PD-1) and its ligand (PD-L1), have received extensive attention in the past decade because of their dramatic clinical outcomes in advanced malignancies. However, both primary and acquired resistance becomes one of the major obstacles, which greatly limits the long-lasting ...

PD-L1/PD-1 Axis in Glioblastoma Multiforme [PDF]

International Journal of Molecular Sciences, 2019
Glioblastoma (GBM) is the most popular primary central nervous system cancer and has an extremely expansive course. Aggressive tumor growth correlates with short median overall survival (OS) oscillating between 14 and 17 months. The survival rate of patients in a three-year follow up oscillates around 10%.
