FOLR2 and neoplasm: In syngeneic murine tumour models of C57BL/6 mice bearing ID8 RFP-fLuc tumors (which lack mFRβ expression), transfer of CAR-T cells following cyclophosphamide preconditioning selectively eliminated FRβ+ TAMs, recruited pro-inflammatory monocytes and tumor-specific CD8+ T cells, and reduced tumor growth.
