  • Publication number: 20100075402
    Abstract: A hybrid protein includes two coexpressed amino acid sequences forming a dimer. Each sequence contains the binding portion of a receptor, such as TBP1 or TBP2, or a ligand, such as IL-6, IFN-? and TPO, linked to a subunit of a natural heterodimeric scaffold. Each coexpressed sequence contains a corresponding subunit so as to form a heterodimer upon expression.

  • Patent number: 6096537
    Abstract: Cells suitable for transplantation which have at least two different epitopes on a surface antigen altered prior to transplantation to inhibit rejection of the cells following transplantation into an allogeneic or xenogeneic recipient are disclosed. These cells are more successfully transplanted than cells which have only a single epitope on the surface antigen altered. Preferably, the antigen on the cell surface which is altered is an MHC class I antigen. Two different epitopes on an MHC class I antigen can be altered by contacting the cell with two molecules, such as antibodies or fragments thereof (e.g., F(ab').sub.2 fragments), which bind to two different epitopes on the antigen. Preferred epitopes on human MHC class I antigens to be altered are epitopes recognized by the monoclonal antibodies W6/32 and PT85. Improved methods for transplantation utilizing cells which have at least two different epitopes on a surface antigen altered prior to transplantation are also disclosed.

  • Patent number: 5986068
    Abstract: Described are new glycoprotein hormones capable of competing with natural hormones for the normal receptor binding sites but substantially incapable of effecting post receptor activities. The glycoprotein hormones of the present invention have had specific (rather than all) oligosaccharide chains removed so as to effectively diminish biologic activity while not significantly reducing plasma half-life, thus improving the molecules effectiveness as an antagonist compared with conventionally-produced molecules. The preferred glycoprotein hormones are ideally obtained by site-directed mutagenesis to selectively deglycosylate the protein. Also described are therapeutic treatments comprising the administration of the recombinant glycoprotein hormones of the present invention as hormone antagonists.

  • Patent number: 5674711
