Definition

A preparation of autologous activated T cells that have been engineered to express chimeric antigen receptors (CARs) specific for the tumor-associated antigen (TAA) CD147 (Basigin; EMMPRIN; extracellular matrix metalloproteinase inducer; OX47; 5A11), with potential antineoplastic activity. Upon administration back into the patient, the anti-CD147 CAR T-cells target and induce selective cytotoxicity in CD147-expressing tumor cells. CD147, a cell-surface glycoprotein of the immunoglobulin G (IgG) superfamily, is overexpressed in certain human tumors and plays an important role in tumor cell proliferation, migration, progression, and metastasis.
