Abstract: The present invention discloses a novel secreted polypeptide, termed Osteoprotegerin, which is a member of the tumor necrosis factor receptor superfamily and is involved in the regulation of bone metabolism. Also disclosed are nucleic acids encoding Osteoprotegerin, polypeptides, recombinant vectors and host cells for expression, antibodies which bind Osteoprotegerin, and pharmaceutical compositions. The polypeptides are used to treat bone diseases characterized by increased resorption such as osteoporosis.

Abstract: A novel neurotrophic factor referred to as glial cell line-derived neurotrophic factor (GDNF) has been identified and isolated from serum free growth medium of B49 glioblastoma cells. Rat and human genes encoding GDNF have been cloned and sequenced. A gene encoding GDNF has been subcloned into a vector, and the vector has been used to transform a host cell in order to produce biologically active GDNF in a recombinant DNA process. An implantable device containing recombinant GDNF secreting cells encapsulated in a semipermeable membrane may be used to treat nerve damage in patients suffering from disorders such as Parkinson's disease.

Abstract: The present invention provides substantially purified UDP-N-acetylglucosamine: .alpha.-6-D-mannoside .beta.-1,6-N-acetylglucosaminyl transferase (GlcNAc T-V; EC 2.4.1.155) proteins and antibodies which specifically bind GlcNAc T-V. The present invention also provides polynucleotide sequences and oligonucleotide probes capable of specifically hybridizing to nucleic acid sequences which encode GlcNAc T-V, and cDNA and genomic clones encoding GlcNAc T-V, as well as nucleotide sequences encoding GlcNAc T-V, as specifically exemplified by GlcNAc T-V coding sequences from rat, hamster, mouse and human.

Abstract: The present invention encompasses methods for preventing and treating multiple sclerosis by administering to patients in need thereof a therapeutically effective amount of IFN-con in combination with IL-1ra.
Abstract: Disclosed are novel polypeptides possessing part or all of the primary structural conformation and one or more of the biological properties of a mammalian (e.g., human) pluripotent granulocyte colony-stimulating factor ("hpG-CSF") which are characterized in preferred forms by being the product of procaryotic or eucaryotic host expression of an exogenous DNA sequence. Sequences coding for part or all of the sequence of amino acid residues of hpG-CSF or for analogs thereof may be incorporated into autonomously replicating plasmid or viral vectors employed to transform or transfect suitable procaryotic or eucaryotic host cells such as bacteria, yeast or vertebrate cells in culture. Products of expression of the DNA sequences display, e.g., the physical and immunological properties and in vitro biological activities of isolates of hpG-CSF derived from natural sources. Disclosed also are chemically synthesized polypeptides sharing the biochemical and immunological properties of hpG-CSF.
Abstract: Nucleic acid molecules are described which are useful in vectors, transformed or transfected host cells, and methods for the recombinant expression of hepatocyte growth-specific polypeptide members of the FGF family.
