key word:Humanized Mouse Model of Fcγ Receptors
Between-species differences in Fcγ receptors limit the use of mice as a preclinical model to study antibody function. We map human and murine Fcγ receptors expression, and introduce a novel mouse line which expresses human FcγRI, FcγRIIA/B, FcγRIIIA/B and FcRn, replacing their murine counterparts. This resource and unique model will advance the preclinical assessment of antibody-based therapeutics.
