PD-1 and Autoimmunity

Critical Reviews™ in Immunology, 2011
An initiating T cell response requires both costimulatory signaling and T cell receptor/MHC binding. The immune system balances positive and negative costimulatory signal pathways to activate and deactivate T cells. This review focuses primarily on PD-1 and its ligands, which form a crucial inhibitory costimulatory pathway for maintaining peripheral ...

PD-1–PD-1 ligand interaction contributes to immunosuppressive microenvironment of Hodgkin lymphoma

Blood, 2008
AbstractProgrammed death-1 (PD-1)–PD-1 ligand (PD-L) signaling system is involved in the functional impairment of T cells such as in chronic viral infection or tumor immune evasion. We examined PD-L expression in lymphoid cell lines and found that they were up-regulated on Hodgkin lymphoma (HL) and several T-cell lymphomas but not on B-cell lymphomas ...

Anti–PD-1 Therapy in Melanoma

Seminars in Oncology, 2015
Immune-regulatory mechanisms are used by cancer to hide from the immune system. Advances and in-depth understanding of the biology of melanoma and its interaction with the immune system have led to the development of some of antagonistic antibodies to the programmed death 1 pathway (PD-1) and one of its ligands, programmed death ligand 1 (PD-L1), which
