Abstract:
Tumor Necrosis Factor (TNF) Inhibitory Protein is isolated and substantially purified. It has the ability to inhibit: (a) the binding of TNF to its receptors, and (b) the cytotoxic effect of TNF. TNF Inhibitory Protein and salts, functional derivatives and active fractions thereof can be used to antagonize the deleterious effects of TNF.
Abstract:
Tumor Necrosis Factor Binding Protein I (TBP-I), precursors and analogs thereof, are produced by transfecting eukaryotic cells with an expression vector comprising al DNA molecule encoding the whole human type I TNF receptor or a soluble domain thereof, and culturing the transfected cells, whereby the soluble proteins are secreted into the medium.
Abstract:
Human natural IFN-.beta.2/IL-6 receptor and its soluble extracellular fragment are provided in substantially purified form and are shown to stimulate and to enhance beneficial effects of IFN-.beta.2/IL-6, such as its antiproliferative activity. Polyclonal and monoclonal antibodies raised against the soluble fragment of the receptor are also provided.
Abstract:
Antibodies to TNF Binding Protein I (TBP-I) are provided that can be used in diagnostic assays and as pharmaceutical agents for either inhibiting or mimicking the effects of TNF on cells.
Abstract:
An isolated DNA molecule has the sequence of encoding a fragment of encoding Tumor Necrosis Factor (TNF) Binding Protein II. It has a length sufficient to serve as an immunogen for raising antibodies against a polypeptide that is a fragment of TNF Binding Protein II. The DNA may be used to produce replicable expression vehicles and prokaryotic or eukaryotic expression host cells. Such host cells may be used to produce polypeptides encoded by such DNA molecules.
Abstract:
Antibodies to Tumor Necrosis Factor receptors (TNF-Rs) which inhibit the cytocidal effect of TNF but not its binding to the TNF-Rs, and ligands interacting with other receptors of the TNF/NGF family, are provided together with methods of producing them. The antibodies preferably bind to the fourth cysteine rich domain of the p75 TNF receptor or to the region between said fourth cysteine rich domain and the cell membrane.
Abstract:
Tumor Necrosis Factor (TNF) Inhibitory Protein is isolated and substantially purified and the DNA that encodes the TNF inhibitory protein, vectors, host cells, and a recombinant method for producing the encoded protein are also set forth. It has the ability to inhibit: (a) the binding of TNF to its receptors, and (b) the cytotoxic effect of TNF. TNF Inhibitory Protein and salts, functional derivatives and active fractions thereof can be used to antagonize the deleterious effects of TNF.
Abstract:
The present invention relates to an immunological method and kit for monitoring recruitment of a protein to the intracellular domain of a receptor in intact cells.
Abstract:
Recombinant DNA encoding Tumor Necrosis Factor (TNF) Inhibitory Protein, or an active fragment thereof, is obtained. The TNF Inhibitory Protein has the ability to inhibit: (a) the binding of TNF to its receptors, and (b) the cytotoxic effect of TNF. TNF Inhibitory Protein and salts, functional derivatives and active fractions thereof can be used to antagonize the deleterious effects of TNF by eliminating TNF from the body, and to reduce the cytotoxic activity of TNF by binding to TNF and thereby to inhibit the binding of TNF to its receptors. The DNA may be in an expression vector. Host cells transfected with such an expression vector may be used to produce the TNF Inhibitory Protein.
