Abstract:
A mouse with a humanization of the mIL-3 gene and the mGM-CSF gene, a knockout of a mRAG gene, and a knockout of a mII2rg subunit gene; and optionally a humanization of the TPO gene is described. A RAG/II2rg KO/hTPO knock-in mouse is described. A mouse engrafted with human hematopoietic stem cells (HSCs) that maintains a human immune cell (HIC) population derived from the HSCs and that is infectable by a human pathogen, e.g., S. typhi or M. tuberculosis is described. A mouse that models a human pathogen infection that is poorly modeled in mice is described, e.g., a mouse that models a human mycobacterial infection, wherein the mouse develops one or more granulomas comprising human immune cells. A mouse that comprises a human hematopoietic malignancy that originates from an early human hematopoietic cells is described, e.g., a myeloid leukemia or a myeloproliferative neoplasia.
Abstract:
A method for engineering and utilizing large DNA vectors to target, via homologous recombination, and modify, in any desirable fashion, endogenous genes and chromosomal loci in eukaryotic cells. These large DNA targeting vectors for eukaryotic cells, termed LTVECs, are derived from fragments of cloned genomic DNA larger than those typically used by other approaches intended to perform homologous targeting in eukaryotic cells. Also provided is a rapid and convenient method of detecting eukaryotic cells in which the LTVEC has correctly targeted and modified the desired endogenous gene(s) or chromosomal locus (loci) as well as the use of these cells to generate organisms bearing the genetic modification.
Abstract:
A fusion protein comprising at least one IGF1 variant component and a fusion component (F), and, optionally, a signal sequence, exhibits improved stability relative to the native IGF1 or IGF2 polypeptide. The fusion component (F) may be a multimerizing component, such as an immunoglobulin domain, in particular, the Fc domain of IgG or a heavy chain of IgG. IGF1 variants were shown to have improved ability to increase muscle mass in a subject suffering from muscle atrophy caused by cachexia, immobilization, aging, chronic disease, cancer, hereditary condition, an atrophy-causing agent, and the like. IGF1 variants are also effective in decreasing blood glucose in a subject suffering from diabetes or hyperglycemia.
Abstract:
Methods of treating, inhibiting, or ameliorating Familial Mediterranean Fever (FMF) by administering to a subject in need thereof a therapeutically effective amount of an interleukin 1 (IL-1) antagonist, are provided. The IL-1 antagonist can be an antibody or derivative thereof, which is capable of blocking or inhibiting the biological action of IL-1, thereby treating, inhibiting or ameliorating FMF. Also provided are methods of treating, inhibiting, or ameliorating FMF by administering a therapeutically effective amount of an IL-1 antagonist in combination with additional therapeutic agents, including IL-1-specific fusion proteins, TNF inhibitors, NSAIDs, steroids, and the like.
Abstract:
Modified chimeric polypeptides with improved pharmacokinetics are disclosed. Specifically, modified chimeric Flt1 receptor polypeptides that have been modified in such a way as to improve their pharmacokinetic profile are disclosed. Also disclosed are methods of making and using the modified polypeptides including but not limited to using the modified polypeptides to decrease or inhibit plasma leakage and/or vascular permeability in a mammal.
Abstract:
The present invention provides a fusion polypeptide capable of binding a cytokine to form a nonfunctional complex. It also provides a nucleic acid sequence encoding the fusion polypeptide and methods of making and uses for the fusion polypeptide.
Abstract:
Methods of treating, inhibiting, or ameliorating an autoinflammatory disorder, disease, or condition in a subject in need thereof, comprising administering to a subject in need a therapeutic amount of an interleukin 1 (IL-1) antagonist, wherein the autoinflammatory disorder, disease, or condition is treated, inhibited, or ameliorated. The IL-1 antagonist is an IL-1 trap, preferably comprising a sequence selected from the group consisting of SEQ ID NO: 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, or a substantially identical having at least 95% identity to the sequence shown in SEQ ID NO: 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26 and capable of binding and inhibiting IL-1. The therapeutic methods are useful for treating a human adult or child suffering from Neonatal Onset Multisystem Inflammatory Disorder (NOMID/CINCA), Muckle-Wells Syndrome (MWS), Familial Cold Autoinflammatory Syndrome (FCAS), familial mediterranean fever (FMF), or systemic onset juvenile rheumatoid arthritis (Still's Disease).

Abstract:
A method of reducing or preventing hypertension associated with administration of a vascular endothelial growth factor (VEGF) antagonist in a human subjects suffering from a disease or condition treatable with a VEGF antagonist in which is it desirable to reduce or prevent hypertension. The method is particularly useful for treatment of patients unresponsive to treatment with a VEGF inhibitor administered intravenously.
