  • Patent number: 9273108
    Abstract: This invention relates to a recombinant human G-CSF (rhG-CSF) dimer and its use in the treatment of neurological disorder. In particular, upon ischemic neural injury in animal, this invention can be used to protect neurons with the use of rhG-CSF dimer such that function of injured nerves can be restored. Serum half-life of G-CSF dimer of this invention is prolonged and the biological activity thereof is increased.

  • Publication number: 20080181897
    Abstract: The invention relates to agonist molecules which specifically bind to or interact with human G-CSF receptor and dimerize the receptor or activate phosphorylation of kinases associated with the receptor to stimulate cell proliferation and differentiation. Such agonist molecules include monoclonal antibodies, or fragments, homologues or analogues thereof, or peptides or organic compounds. Two examples of mouse monoclonal agonist antibodies are disclosed: mAb163-93 and mAb174-74-11.

  • Patent number: 7250493
    Abstract: Fc fusion proteins of human EPO with increased biological activities relative to rHuEPO on a molar basis are disclosed. The HuEPO-L-vFc fusion protein comprises HuEPO, a flexible peptide linker of about 20 or fewer amino acids, and a human IgG Fc variant. The Fc variant is of a non-lytic nature and shows minimal undesirable Fc-mediated side effects. A method is also disclosed to make or produce such fusion proteins at high expression levels. Such HuEPO-L-vFc fusion proteins exhibit extended serum half-life and increased biological activities, leading to improved pharmacokinetics and pharmacodynamics, thus fewer injections will be needed within a period of time.

  • Patent number: 6534058
    Abstract: The invention relates to C5 inhibitors, which inhibit type II endothelial cell activation, wherein the inhibition is manifested by the suppression of E-selectin. These inhibitors are useful in treatment of delayed xenograft rejection or acute vascular rejection. The inhibitors include antibody molecules, as well as homologues, analogues and modified or derived forms thereof, including immunoglobulin fragments like Fab, F(ab′)2 and Fv, small molecules, including peptides, oligonucleotides, peptidomimetics and organic compounds. Examples of monoclonal antibodies, which bind to and inhibit C5, were generated and are designated MAb 137-76 and MAb 137-30.
