To further evaluate whether 6MW3211 could induce the macrophage phagocytosis of tumor cells or not, wild-type Raji cells with no or low hPD-L1 expression, and Raji cells with hPD-L1 overexpression (Raji-hPD-L1) were used for in vitro phagocytosis assays. This evidence concerns the gene CD274 and neoplasm.
