    摘要: Genetically modified mice and methods for making an using them are provided, wherein the mice comprise a replacement of all or substantially all immunoglobulin heavy chain V gene segments, D gene segments, and J gene segments with at least one light chain V gene segment and at least one light chain J gene segment. Mice that make binding proteins that comprise a light chain variable domain operably linked to a heavy chain constant region are provided. Binding proteins that contain an immunoglobulin light chain variable domain, including a somatically hypermutated light chain variable domain, fused with a heavy chain constant region, are provided. Modified cells, embryos, and mice that encode sequences for making the binding proteins are provided.

    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 FcγR locus, and wherein the mouse is capable of expressing a functional FcRγ-chain. Genetically modified mice are described, including mice that express low affinity human FcγR genes from the endogenous FcγR locus, and wherein the mice comprise a functional FcRγ-chain. Genetically modified mice that express up to five low affinity human FcγR genes on accessory cells of the host immune system are provided.

    摘要: Methods and compositions for using genetically modified non-human animals are provided, wherein the genetic modification comprises a humanization of the one or more extracellular pore loops of a NaV1.7 channel protein or a complete humanization of an endogenous NaV1.7 gene. Methods for using isolated DRG cultures from genetically modified non-human animals are also provided, wherein the isolated DRG express a human or chimeric NaV1.7 protein on the surface, in particular measuring primary nociceptive activation through the release of calcitonin gene-related peptide (CGRP) in isolated DRG in vitro, and wherein the isolated DRG cultures are capable of generating action potentials and communicating through an excitable signal via the expressed human or chimeric NaV1.7 protein the cell surface. In vivo and in vitro methods for characterizing NaV1.7-specific antagonists and evaluation of corresponding therapeutic potential for NaV1.7-mediated disease are also provided.
