摘要:
Genetically modified non human animals and methods and compositions for making and using them are provided wherein the genetic modification comprises a deletion of the endogenous low affinity Fc?R locus and wherein the mouse is capable of expressing a functional FcR? chain. Genetically modified mice are described including mice that express low affinity human Fc?R genes from the endogenous Fc?R locus and wherein the mice comprise a functional FcR? chain. Genetically modified mice that express up to five low affinity human Fc?R genes on accessory cells of the host immune system are provided.
