  "term": "anti-PD-1 monoclonal antibody OSE-279",
  "field": "Oncology and biomedicine",
  "definition": "A human immunoglobulin G4 (IgG4) monoclonal antibody directed against the negative immunoregulatory human cell receptor programmed cell death protein 1 (PD-1; PDCD1; CD279), with potential immune checkpoint inhibitory and antineoplastic activities. Upon administration, anti-PD-1 monoclonal antibody OSE-279 targets, binds to and inhibits PD-1 and its downstream signaling pathways. This may restore immune function through the activation of T cells and T-cell-mediated immune responses against tumor cells. PD-1, a transmembrane protein in the immunoglobulin superfamily (IgSF) expressed on T cells, functions as an immune checkpoint that negatively regulates T-cell activation and effector function when activated by its ligands programmed cell death-1 ligand 1 (PD-L1; cluster of differentiation 274; CD274) or 2 (PD-L2; CD273); it plays an important role in tumor evasion from host immunity.",
