    摘要: Genetically modified non-human animals and methods and compositions for making and using them are provided, wherein the genetic modification comprises a humanization of an extracellular loop of an endogenous NaV channel gene, in particular a humanization of the one or more extracellular pore loops of a NaV1.7 channel protein. Genetically modified non-human animals are also provided, wherein the genetic modification comprises replacement of an endogenous NaV channel gene, in particular a replacement of the endogenous NaV1.7 gene with a human NaV1.7 gene, and wherein the genetically modified non-human animals are capable of generating action potentials and communicating through the excitable cells of the genetically modified non-human animals via the expressed human or humanized NaV1.7 protein the surface of the excitable cells. Genetically modified mice are described, including mice that express the human or humanized NaV1.7 gene from the endogenous NaV1.7 locus, and wherein the mice comprise functional β-subunits.

    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 in an immunoglobulin constant region CH1 gene (optionally a deletion in a hinge region) of an IgG, IgA, IgD, and/or IgE, and wherein the mouse is capable of expressing a functional IgM. Genetically modified mice are described, including mice having a functional IgM gene and modified to have a deletion of a CH1 domain and a hinge region in a heavy chain constant domain that is not an IgM, e.g., in an IgG heavy chain constant domain. Genetically modified mice that make human variable/mouse constant chimeric heavy chain antibodies (antibodies that lack a light chain), fully mouse heavy chain antibodies, or fully human heavy chain antibodies are provided.
