  "term": "PD-L1/PD-L2/VISTA antagonist CA-170",
  "field": "Oncology and biomedicine",
  "definition": "An orally bioavailable small molecule inhibitor of the immune checkpoint regulatory proteins programmed cell death ligand-1 (PD-L1; B7-H1; CD274), PD-L2, and V-domain immunoglobulin (Ig) suppressor of T-cell activation (VISTA; programmed death 1 homolog; PD1H; PD-1H), with potential negative immune checkpoint regulatory and antineoplastic activities. Upon oral administration, PD-L1/PD-L2/VISTA antagonist CA-170 targets and binds to PD-L1, PD-L2 and VISTA. This inhibits PD-L1/PD-L2/VISTA-mediated signaling, abrogates the PD-L1-, PD-L2- and VISTA-induced suppression of T-lymphocyte immune responses, enhances cytotoxic T-cell proliferation and activation against tumor cells, increases cytokine production by T-cells, and inhibits tumor cell growth. PD-L1, PD-L2 and VISTA, negative checkpoint molecules of immune activation, play key roles in the suppression of T-cell functions.",
