The long-awaited magic bullets: therapeutic human monoclonal antibodies from transgenic mice
Abstract
The ability to produce a diverse repertoire of fully human monoclonal antibodies (mAbs) may have significant applications to human therapy. This update describes the creation of a novel tool for the production of therapeutic human mAbs: a mouse strain engineered to produce a large range of human antibodies in the absence of mouse antibodies. This strain, XenoMouse, has been generated by the introduction of large segments of human immunoglobulin loci, containing the majority of the human antibody gene repertoire, into mice deficient in mouse antibody production. The mice produce a diverse array of authentic fully human IgGkappa antibodies. Upon immunisation with multiple human antigens the mice generate large panels of high affinity, antigen-specific fully human mAbs with therapeutic activities. XenoMouse-derived hybridomas were shown to be stable, producing significant levels of human mAbs. XenoMouse technology represents an efficient and reliable tool for the production of therapeutic human mAbs, which can accelerate the evaluation and validation of antibody therapy in human disease.
