  • Patent number: 11950578
    Abstract: Mice are provided that comprise a reduction or deletion of ADAM6 activity from an endogenous ADAM6 locus, or that lack an endogenous locus encoding a mouse ADAM6 protein, wherein the mice comprise a sequence encoding an ADAM6 or ortholog or homolog or fragment thereof that is functional in a male mouse. In one embodiment, the sequence is an ectopic ADAM6 sequence or a sequence that confers upon a male mouse the ability to generate offspring by mating. Mice and cells with genetically modified immunoglobulin heavy chain loci that comprise an ectopic nucleotide sequence encoding a mouse ADAM6 or functional fragment or homolog or ortholog thereof are also provided.

The genetically modified non-human animals comprise a nucleic acid encoding human IL-6 operably linked to an IL-6 promoter. In some instances, the genetically modified non-human animal expressing human IL-6 also expresses at least one of human M-CSF, human IL-3, human GM-CSF, human SIRPa or human TPO. In some instances, the genetically modified non-human animal is immunodeficient. In some such instances, the genetically modified non-human animal is engrafted with healthy or diseased human hematopoietic cells. Also provided are methods for using the subject genetically modified non-human animals in modeling human hematopoietic cell development, function, and/or disease, as well as reagents and kits thereof that find use in making the subject genetically modified non-human animals and/or practicing the subject methods.

  • Patent number: 11934740
    Abstract: Methods, systems and apparatus for associating electronic devices together based on received audio commands are described. Methods for associating an audio-controlled device with a physically separate display screen device such that information responses can then be provided in both audio and graphic formats using the two devices in conjunction with each other are described. The audio-controlled device can receive audio commands that can be analyzed to determine the author, which can then be used to further streamline the association operation.
