  • Patent number: 8883496
    Abstract: 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.

  • Publication number: 20110081681
    Abstract: A human antibody or antigen-binding fragment of an antibody that specifically binds human CD20 and is capable of inducing complement dependent cytotoxicity (CDC), and is capable of increasing symptom free survival time between about 2-fold to about 9-fold or more, relative to control-treated animals in a mouse model of human lymphoma. The antibody or antigen-binding fragment thereof is useful in a therapeutic method for treating a CD20-mediated disease or condition, such as for example, non-Hodgkin's lymphoma, rheumatoid arthritis, systemic lupus erythematosus, Crohn's disease, chronic lymphocytic leukemia, and inflammatory diseases.
