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.

FC fusion proteins of human erythropoietin with increased biological activities

Fc fusion proteins of human G-CSF with increased biological activities relative to rhG-CSF on a molar basis are disclosed. The hG-CSF-L-vFc fusion protein comprises hG-CSF, 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 hG-CSF-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.

Chimeral viral-neutralizing, particularly HIV-neutralizing, immunoglobulins made up of a non-human antigen binding region and a human constant region are described.

Chimeric viral-neutralizing immunoglobulins

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&prime;) 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.

Anti-C5 monoclonal antibodies

A particular epitope located within the CD4-binding region of gpl20 of HIV-1, and antibodies specific for the epitope which can inhibit HIV-1 infection of human cells by diverse strains and isolates of the virus, is disclosed. The antibodies are useful for a number of purposes, including diagnosis of HIV-1 infection.
