Fig. 1From: Identification of active small-molecule modulators targeting the novel immune checkpoint VISTAa Antagonist ligands (light blue) interacting with local residues of the murine VISTA protein (green). Residues on the VISTA protein interacting with antagonist ligands are highlighted in red. a Shows the whole VISTA protein extracellular domain and the docked positions of the ligand (6809-0223). b Structure of compound 6809-0223Back to article page
