Murine/human chimeric antibodies with specificity for the human TCR-alpha/beta have been produced by genetic engineering. The L and H chain V region exons encoding the murine mAb BMA 031 were isolated and inserted into mammalian expression vectors containing the human kappa and gamma 1 or gamma 4 C region exons. The chimeric genes were transfected into murine Sp2/O hybridoma cells by electroporation and transfectomas secreting chimeric antibody were isolated. Secretion levels ranged from 1 to 7 pg/cell/24 h. The chimeric antibodies bound specifically to T cells and competed effectively with the parental murine mAb for binding to these sites. The ability to promote antibody-dependent cell-mediated cytolysis was significantly enhanced in the chimeric antibodies as compared with murine BMA 031. C-dependent cytolysis, however, was not detectable with any of the antibodies. Chimeric BMA 031 is a clinically relevant, genetically engineered antibody with potential uses in transplantation, graft-vs-host disease, autoimmune diseases and other T cell-related disorders.
