In contrast, FAP(mF3) UCAR T cells also failed to sensitize these tumors to Meso UCAR T-cell cytotoxicity in vivo (Figures S4H, S4I), in agreement with their inability to deplete CAFs or increase CD8+ T-cell infiltration in the tumor stroma (Figures 3H-J). The gene discussed is FAP; the disease is neoplasm.
