  • Patent number: 6610288
    Abstract: Isolated porcine hepatocytes, isolated populations of such hepatocytes and methods for using the hepatocytes to treat subjects with disorders characterized by insufficient liver function are described. The porcine hepatocytes can be either hepatocytes isolated from adult, immature, or embryonic swine. The porcine hepatocytes can be modified to be suitable for transplantation into a xenogeneic subject, for example, by altering an antigen (e.g., an MHC class I antigen) on the cell surface which is capable of stimulating an immune response against the cell in the subject (e.g., by contact with an anti-MHC class I antibody, or a fragment or derivative thereof). The isolated porcine hepatocytes of the invention can be used to treat disorders characterized by insufficient liver function by administering the hepatocytes to a subject having such a disorder.

  • Patent number: 6576236
    Abstract: When stimulated through the T cell receptor(TCR)/CD3 complex without requisite costimulation through the CD28/B7 interaction, T cells enter a state of antigen specific unresponsiveness or anergy. This invention is based, at least in part, on the discovery that signaling though a common cytokine receptor &ggr; chain (e.g., interleukin-2 receptor, interleukin-4 receptor, interleukin-7 receptor) prevents the induction of T cell anergy. This &ggr; chain has been found to be associated with a JAK kinase having a molecular weight of about 116 kD (as determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis) and signaling through the &ggr; chain induces phosphorylation of the JAK kinase. Accordingly, methods for stimulating or inhibiting proliferation by a T cell which expresses a cytokine receptor &ggr; chain are disclosed.

  • Patent number: 6555325
    Abstract: The present invention makes available a rapid, reproducible, robust assay system for screening and identifying pharmaceutically effective compounds that specifically interact with and modulate the activity of a cellular protein, e.g., a receptor or ion channel. The subject assay enables rapid screening of large numbers of compounds to identify those which act as an agonist or antagonist to the bioactivity of the cellular protein. In this system, the first cell is treated with a compound, and functional interaction of this compound with a cellular receptor yields a secreted signal. A second cell, bearing a receptor for this secreted signal, makes use of an indicator gene in a signaling pathway coupled to this second receptor. The subject assays include methods of identifying compounds which specifically modulate, for example, heterologous receptors coupled to the pheromone response pathway in yeast.

    Abstract: Methods for modulating immune responses are provided. The methods involve contacting an immune cell with an agent that modulates interaction of a compound comprising a Lewis antigen with the immune cell such that production by the immune cell of at least one cytokine that regulates development of a T helper type 1 or T helper type 2 response is modulated. Stimulatory forms of the agent can comprise multivalent conjugates containing a Lewis antigen, such as a Lewisy, Lewisx or Lewisa-containing oligosaccharide, or a derivative thereof. Inhibitory forms of the agent can comprise non-crosslinked forms of a Lewis antigen, such as a Lewisy, Lewisx or Lewisa-containing oligosaccharide, or a derivative thereof. Stimulatory forms of the agent can be used in methods for stimulating a specific immune response to an antigen in vivo. Inhibitory forms of the agent can be used in methods for inhibiting allergic responses in vivo.
