Autologous human T lymphocytes transduced with a recombinant lentiviral vector encoding a chimeric T cell receptor consisting of an anti-CD22 single chain variable fragment (scFv) and the co-stimulatory domain 4-1BB (CD137) coupled to the zeta chain of the TCR/CD3 complex (CD3-zeta), with potential immunostimulating and antineoplastic activities. Autologous peripheral blood lymphocytes (PBLs) from a patient with CD22-positive cancer are transduced with this lentiviral vector that encodes the CAR gene specific for CD22. After isolation, transduction, expansion in culture and reintroduction into the patient, the anti-CD22 scFv TCRz:41BB-CAR lentiviral vector-transduced autologous T lymphocytes express anti-CD22-CAR on their cell surfaces and bind to the CD22 antigen on tumor cell surfaces. Subsequently, CD22-expressing tumor cells are lysed. CD22, a B-lineage-restricted, transmembrane phosphoglycoprotein, is expressed on malignant B cells. Check for active clinical trials using this agent. (NCI Thesaurus)
