Tumor-specific T-bodies: towards clinical application

  • Zelig Eshhar


 Unlike antibodies, T cells are well suited to penetrate and destroy solid tumors. The T-body approach combines antibody recognition and T cells effector function. It is based on T cells expressing chimeric receptors composed of antibody-derived Fv or scFv as their extracellular recognition elements joined to lymphocyte triggering molecules. This receptors can redirect the specificity of T cells in an MHC independent manner. Upon encountering their target cells, T-bodies are able to undergo specific stimulation for interleukin/cytokine production, and kill hapten-modified or tumor cells in model systems both in vitro and in vivo. T cells expressing chimeric receptors made of antitumor antibodies are able to discriminate between a tumor and normal cell with negligible bystander cytotoxicity. Further studies should be carried out to evaluate and optimize the persistence, homing patterns and reactivation potential of T-bodies in the body.
