摘要:
A system, device, and method for rapid detection of analytes that includes a living, engineered biosensor cell that is typically a component of the mammalian immune system; a reporter protein that is engineered into and expressed by the living, engineered biosensor cell, wherein the reporter protein emits a detectable signal in response to certain predetermined changes in the cytosol of the living, engineered cell; a signal transduction pathway expressed by the living, engineered biosensor cell, wherein the signal transduction pathway controls a biological process within the cytosol of the living, engineered biosensor cell, and wherein the biochemical process, when it occurs, causes the reporter protein to emit a detectable signal; at least one type of detector molecule that is adapted to bind to a specific analyte; at least one analyte that binds to the detector molecule that is specific to that analyte; a plurality of non-antibody signal transducing elements that are either expressed by the living, engineered biosensor cell or that actively bind to a receptor or a receptor component expressed by the living, engineered biosensor cell, wherein each signal transducing element is adapted to receive a detector molecule.
摘要:
The invention provides soluble fusion protein complexes having at least two soluble fusion proteins. The first fusion protein is a biologically active polypeptide covalently linked to an interleukin-15 (IL-15) polypeptide or a functional fragment thereof. The second fusion protein is a second biologically active polypeptide covalently linked to a soluble interleukin-15 receptor alpha (IL-15Rα) polypeptide or a functional fragment thereof. In the complexes of the invention, one or both of the first and second fusion proteins further includes an immunoglobulin Fc domain or a functional fragment thereof; and the first fusion protein binds to the soluble IL-15Rα domain of the second fusion protein to form a soluble fusion protein complex. The invention further provides methods for making and using the complexes of the invention.
摘要:
The present invention is directed to a fusion protein comprising a light chain region of a Clostridial neurotoxin and a heavy chain region of a Clostridial neurotoxin, where the light and heavy chain regions are linked by a disulfide bond. The fusion protein also has a single chain antibody positioned upstream of the light chain region, where the single chain antibody possesses antigen-binding activity. Also disclosed are therapeutic agents, treatment methods, propeptide fusions, isolated nucleic acid molecules, expression systems, host cells, and methods of expressing fusion proteins.
摘要:
The present invention provides methods, compositions, and kits for the treatment of disorders associated with overactivation of FGFR3, such as achondroplasia; bone or cartilage disorders; or vascular smooth muscle disorders, or for the elongation of bone. In some embodiments, the present invention provides polypeptides having a natriuretic peptide fused to an Fc domain of an immunoglobulin. Such polypeptides can be administered to subjects, e.g., subcutaneously, to treat a disorder associated with overactivation of FGFR3, a bone or cartilage disorder, or a vascular smooth muscle disorder, or to elongate bone. The invention also features nucleic acid molecules encoding such polypeptides and the use of the nucleic acid molecules for treating disorders associated with overactivation of FGFR3, bone or cartilage disorders, or vascular smooth muscle disorders, or for elongating bone.
