CVRARTR is an antagonist for programmed cell death ligand-1 (PD-L1) with KD of 281 nM. CVRARTR induces the internalization of PD-L1 and downregulates PD-L1 on the cell surface. CVRARTR restores cytokine secretion and T cell proliferation in cell CT26. CVRARTR exhibits antitumor efficacy against in CT26 homograft mouse model[1].
