摘要:
Fibroblast growth factor-18 (FGF-18) binds with FGF receptors-2 and -3. Compositions comprising an FGF-18 component can be used to target cells that express these receptors. Suitable targets include tumor cells that express constitutively activated forms of FGF receptors-2 and -3.
摘要:
Polypeptide growth factors, methods of making them, polynucleotides encoding them, antibodies to them, and methods of using them are disclosed. The polypeptides comprises an amino acid segment that is at least 90% identical to residues 46-163 of SEQ ID NO:2 or residues 235-345 of SEQ ID NO:2. Multimers of the polypeptides are also disclosed. The polypeptides, multimeric proteins, and polynucleotides can be used in the study and regulation of cell and tissue development, as components of cell culture media, and as diagnostic agents.
摘要:
Novel polypeptide combinations, polynucleotides encoding the polypeptides, and related compositions and methods are disclosed for soluble zalpha11 receptors that may be used as novel cytokine antagonist, and within methods for detecting ligands that stimulate the proliferation and/or development of hematopoietic, lymphoid and myeloid cells in vitro and in vivo. Ligand-binding receptor polypeptides can also be used to block zalpha11 Ligand activity in vitro and in vivo, and may be used in conjunction with zalpha11 Ligand and other cytokines to selectively stimulate the immune system. The present invention also includes methods for producing the protein, uses therefor and antibodies thereto.
摘要:
The present invention relates to blocking, inhibiting, reducing, antagonizing or neutralizing the activity of IL-17, IL-23 via it's p19 subunit or both IL-17 and IL-23 (via p19). IL-17 and IL-23 are cytokines that are involved in inflammatory processes and human disease.
摘要:
The polypeptides, and the polynucleotides encoding for them, described herein are IL-21 antagonists that bind with specificity and exhibit an EC50 that is not detectable in receptor binding studies. These molecules have mutations in the D helix of the IL-21 molecule, and can be used to inhibit the activity of IL-21 with its cognate receptor.
摘要:
The present invention relates to a method of preparing a tetrameric protein comprising culturing a host cell transformed or transfected with an expression vector encoding a fusion protein comprising a vasodialator-stimulated phosphoprotein (VASP) domain and a heterologous protein. In one embodiment, the heterologous protein is a membrane protein, the portion of the heterologous protein that included in the fusion protein is the extracellular domain of that protein, and the resulting fusion protein is soluble. The method can be used to produced homo- and hetero-tetrameric proteins. The present invention also encompasses DNA molecules, expression vectors, and host cells used in the present method and fusion proteins produced by the present method.
摘要:
The present invention provides a newly identified B7 receptor, zB7Rl that functions as lymphocyte inhibitory receptor, which is a PD-I -like molecule and is expressed on T cells. The present invention also provides the discovery of zB7Rl's ability to bind to CD155. Methods and compositions for modulating zB7Rl -mediated negative signaling and interfering with the interaction of its counter-receptor for therapeutic, diagnostic and research purposes are also provided.
