Interestingly, whereas CART-PSMA/saline treatment shaped PSMA surface expression in both WT and Rag1-KO tumor-bearing mice, the treatment with CART-CD19/STING-L only decreased the expression of hPSMA in WT mice (figure 2D and online supplemental figure S1H), indicating that hPSMA was targeted by both CART-PSMA cells and the 2′3′-cGAMP-induced immune response. Here, FOLH1 is linked to neoplasm.
