Abstract

The binding specificity of the murine OKT3 has been transferred into a human antibody framework in order to reduce its immunogenicity. These “humanized” anti-CD3 monoclonal antibodies retain, in vitro, all the properties of native anti-CD3 antibodies, including T cell activation which has been correlated, in vivo, with the severe side-effects observed in transplant recipients after the first administration of the mAb.
