RT Journal Article SR Electronic A1 Powers, Jenny T1 Immunomodulation of Checkpoints Resets Immune System in NSCLC JF MD Conference Express YR 2014 FD SAGE Publications VO 14 IS 3 SP 4 OP 5 DO 10.1177/155989771403001 UL http://mdc.sagepub.com/content/14/3/4.abstract AB Although advances seemed elusive throughout past years, immunotherapy is beginning to fulfill its promise in the treatment of non—small cell lung cancer (NSCLC). For years, researchers have been intrigued by the notion of trying to enlist the immune system to attack tumors; however, little was actually realized until the mechanisms of immune evasion used by tumor cells were defined and immune regulators of the programmed death and programmed death ligand (PD-1—PD-L1) pathway were recently devised. This article discusses the advent of immunotherapy that was made possible by the development of immune checkpoint inhibitors that target the PD-1—PD-L1 pathway.
