Abstract: A novel human cytokine, JE factor, and processes for producing it are disclosed. JE may be used in pharmaceutical preparations for stimulating and/or enhancing immune responsiveness and in wound healing and related tissue repair. containing the factor.

Abstract: Methods are disclosed for refolding proteins of the TGF-&bgr; family of proteins. The methods employ as refolding agents one or more compounds which are acid substituted aminocyclohexanes.

Abstract: Polynucleotides encoding the human IL-11 receptor and fragments thereof are disclosed. IL-11 receptor proteins, methods for their production, inhibitors of binding of human IL-11 and its receptor and methods for their identification are also disclosed.

Abstract: The use of interleukin-11 to prevent, to ameliorate, and to treat a gastrointestinal disorder in a mammal in need of such treatment is disclosed.

Abstract: The present invention relates to a methods for producing recombinant heterodimeric BMP proteins useful in the field of treating bone defects, healing bone injury and in wound healing in general. The invention also relates to the recombinant heterodimers and compositions containing them.

Abstract: Provided by the present invention are topical formulations of Interleukin-11 and methods for treating a variety of disorders, including inflammatory bowel diseases (e.g., Crohn's disease, ulcerative colitis, indeterminate colitis, and infectious colitis), mucositis (e.g., oral mucositis, gastrointestinal mucositis, nasal mucositis, and proctitis), necrotizing enterocolitis, inflammatory skin disorders (e.g., psoriasis, atopic dermatitis, and contact hypersensitivity), aphthous ulcers, pharyngitis, esophagitis, peptic ulcers, gingivitis, periodontitis, and ocular diseases (e.g., conjunctivitis, retinitis, and uveitis).

Abstract: A chemokine, human L105, is disclosed.

Abstract: Compositions and methods for selectively linking a polynucleotide through its 5' or 3' end to one or more preselected materials such as insoluble matrices, solid supports, proteins, small molecular or labels are disclosed. Use of these compositions and methods in the production of diagnostic and affinity reagents are also disclosed.

Abstract: The invention relates to a method of suppressing B1 cell activity in a host (e.g., mammalian, including human) comprising administering to the host an effective amount of IL-12 that significantly suppresses or inhibits B1 cell activity. In addition, the invention relates to a method of treating a B1 cell disorder in a host, comprising administering to the host an effective therapeutic amount of IL-12. The invention further encompasses a method of screening for substances (e.g., proteins, peptides, small molecules) which enhance or suppress the inhibition of B1 cell activity by IL-12. The invention also relates to a substance identified by the methods of screening for a substance which enhances or suppresses IL-12 inhibition of B1 cell activity.

Abstract: Cysteine added variants ("CAVs") of interleukin-3 are provided having one or more cysteine residues substituted for selected naturally occurring amino acid residues, or inserted into the polypeptide sequence, and preferably being further modified by deletion of certain N-terminal amino acids. Such CAVs may be additionally modified by the coupling of sulfhydryl reactive compounds to the introduced cysteine residue(s) without loss of bioactivity to produce selected homogeneously modified IL-3 and improved pharmaceutical compositions containing the same.

Abstract: A composition for isolating and purifying nucleic acid from cell culture medium and a method for isolating and purifying nucleic acid from cell culture medium employing the composition, in which the reagent includes about 1 to 3.5M acetate salt solution, about 4 to 11.2M acetic acid, about 1 to 40% by volume phenol, and about 1 to 40% by volume chloroform.
