  • ligand of PDL1, inhibiting T cell activation
  • dendritic cell molecule with costimulatory properties for T cells
  • play with its ligand an important role in the negative regulation of immune reactions
  • expressed following activation and is involved in the regulation of T cell function, highlighting the level of complexity in the T cell cosignaling network
  • its expression is involved in brain endothelial cells contribution to control T cell transmigration into the CNS

    small molecule
    protein
  • binding to PDCD1
  • PDCD1-PDCDlLG2 interaction contributes to immunosuppressive microenvironment of Hodgkin lymphoma
  • differential molecular mechanisms of interaction of CD274 and PDCD1LG2 with PDCD1, suggesting possible new approach for the therapy of chronic infection, cancer and transplantation (
  • PDCD1 is a potent inhibitory receptor of T cells which binds to two different ligands, namely CD274 and PDCD1LG2, and upon binding, it inhibits T cell activation, differentiation, and proliferation, leading to a state of immune tolerance
