Abstract: Current strategies for the production of therapeutic mAbs include he use of mammalian cell systems to recombinantly produce Abs erived from mice bearing human Ig transgenes humanization of odent Abs or phage libraries. Generation of hybridomas secreting uman mAbs has been previously reported; however this approach as not been fully exploited for immunotherapy development. e previously reported the use of transient regulation of ellular DNA mismatch repair processes to enhance traits (e.g. ffinity and titers) of mAb-producing cell lines including hybridomas. e reasoned that this process named morphogenics could e used to improve suboptimal hybridoma cells generated by eans of ex vivo immunization and immortalization of antigenspecific uman B cells for therapeutic Ab development. Here we resent a platform process that combines hybridoma and morphogenics echnologies for the generation of fully human mAbs pecific for disease-associated human antigens. We were able to enerate hybridoma lines secreting mAbs with high binding specificity nd biological activity. One mAb with strong neutralizing ctivity against human granulocyte–macrophage colony-stimulating actor was identified that is now considered for preclinical evelopment for autoimmune disease indications. Moreover hese hybridoma cells have proven suitable for genetic optimization sing the morphogenics process and have shown potential for arge-scale manufacturing.
