  • Publication number: 20150007357
    Abstract: The invention is directed to a method of determining whether an agent causes immune toxicity in a human comprising administering the agent to a non-human mammal that has been engrafted with human hematopoietic stem cells (HSCs) and administered one or more human cytokines; and determining whether the agent causes immune toxicity in the non-human mammal. If the agent causes immune toxicity in the non-human mammal then the agent causes toxicity in a human. The invention is also directed to a method of determining whether administration of an agent causes cytokine release syndrome in an individual in need thereof comprising administering the agent to a non-human mammal that has been engrafted with HSCs and administered one or more human cytokines; and determining whether the agent causes cytokine release syndrome in the non-human mammal. If the agent causes cytokine release syndrome in the non-human mammal then the agent will cause cytokine release syndrome in the human.

  • Publication number: 20120251528
    Abstract: The present invention describes Photolabile Compounds methods for use of the compounds. The Photolabile Compounds have a photoreleasable ligand, which can be biologically active, and which is photoreleased from the compound upon exposure to light. In some embodiments, the Photolabile Compounds comprise a light antenna, such as a labeling molecule or an active derivative thereof. In one embodiment, the light is visible light, which is not detrimental to the viability of biological samples, such as cells and tissues, in which the released organic molecule is bioactive and can have a therapeutic effect. In another embodiment, the photoreleasable ligand can be a labeling molecule, such as a fluorescent molecule.

  • Publication number: 20120157667
    Abstract: Provided herein are methods of reconstituting functional human blood cell lineages in a non-human mammal comprising introducing human hematopoietic stem cells (HSCs) and nucleic acid encoding one or more human cytokines into an immunodeficient non-human mammal. The non-human mammal is maintained under conditions in which the nucleic acid is expressed and the human HSCs differentiate into functional human blood cell lineages in the non-human mammal, thereby reconstituting functional human blood cell lineages in the non-human mammal. Also provided are methods of producing human antibodies directed against an immunogen in a non-human mammal, hybridomas that secrete the monoclonal antibodies as well as antibodies (e.g., polyclonal antibodies; monoclonal antibodies) produced by the B cells and non-human mammals produced by the methods.
