Immunopharmacology Ligand
Comment: This is one of the ligands for the PD-1 receptor. It is a single-pass type I membrane protein. The PD-L1/PD-1 interaction is an established immune checkpoint. Both the ligand and receptor are targets for novel immuno-oncology therapeutics, as over-expression of either of these proteins is a mechanism used by tumour cells to evade immune detection and destruction. Already the target of approved immunotherapeutics in the form of monoclonal antibodies, small molecules targeting the PD-1/PD-L1 checkpoint are now in development to address the shortcomings associated with the current antibody therapies (including, poor susceptibility rate to single immune checkpoint pathway inhibitors, long half-life of antibodies and association with the development of adverse events, problems connected to the requirement for intravenous infusions) [7,16].
