CXCL9 and neoplasm: As demonstrated in Fig. 8b, NPSur-C9AP induced high expression of CXCL9 and αPD-L1 proteins in the four types of tumor cells (B16-F10, CT26, PanC02, and 4T1 cells), but hardly induced the expression of CXCL9 and αPD-L1 proteins in the four types of primary normal cells derived from mouse skin, colon, pancreas, and breast tissues.
