A nucleic acid sequence is provided that encodes a chimeric protein comprising a ligand that comprises a naturally occurring or modified follicle stimulating hormone sequence, e.g., an FSHp sequence, or fragment thereof, which ligand binds to human follicle stimulating hormone (FSH) receptor, linked to either (a) a nucleic acid sequence that encodes an extracellular hinge domain, a transmembrane domain, a co-stimulatory signaling region, and a signaling endodomain; or (b) a nucleic acid sequence that encodes a ligand that binds to NKG2D. The vector containing the nucleic acid sequence, the chimeric proteins so encoded, and modified T cells expressing the chimeric protein, as well as method of using these compositions for the treatment of FSHR-expressing cancers or tumor cells are also provided.
