摘要:
Provided is a method of preparing a physiologically active polypeptide conjugate, in which a physiologically active polypeptide and a non-peptidyl polymer are linked to each other via a covalent bond. The method is to improve an overall yield of the physiologically active polypeptide conjugate by improving a reaction of the non-peptidyl polymer and the physiologically active polypeptide, and particularly, the method is to prepare a physiologically active polypeptide conjugate in a high yield by performing a two-step reaction through selective precipitation. The preparation method of the present invention is used to produce a non-peptidyl polymer-physiologically active polypeptide conjugate and a physiologically active polypeptide-physiologically active carrier conjugate in a high yield, and therefore, the method may be used in the development of long-acting formulations of various peptide drugs which maintain in vivo activity at a relatively high level and have remarkably increased blood half-life.

摘要:
A nucleic acid sequence is provided that encodes a chimeric protein comprising a ligand that comprises a naturally occurring or modified follicle stimulating hormone sequence, e.g., an FSHp sequence, or fragment thereof, which ligand binds to human follicle stimulating hormone (FSH) receptor, linked to either (a) a nucleic acid sequence that encodes an extracellular hinge domain, a transmembrane domain, a co-stimulatory signaling region, and a signaling endodomain; or (b) a nucleic acid sequence that encodes a ligand that binds to NKG2D. The vector containing the nucleic acid sequence, the chimeric proteins so encoded, and modified T cells expressing the chimeric protein, as well as method of using these compositions for the treatment of FSHR-expressing cancers or tumor cells are also provided.

摘要:
Amphipathic lytic peptides are ideally suited to use in a ligand/cytotoxin combination to specifically inhibit cells that are driven by or are dependent upon a specific ligand interaction; for example, to induce sterility or long-term contraception, or to attack tumor cells, or to selectively lyse virally-infected cells, or to attack lymphocytes responsible for autoimmune diseases. The peptides act directly on cell membranes, and need not be internalized. Administering a combination of gonadotropin-releasing hormone (GnRH) (or a GnRH agonist) and a membrane-active lytic peptide produces long-term contraception or sterilization in animals in vivo. Administering in vivo a combination of a ligand and a membrane-active lytic peptide kills cells with a receptor for the ligand. The compounds are relatively small, and are not antigenic. Lysis of gonadotropes has been observed to be very rapid (on the order of ten minutes). Lysis of tumor cells is rapid. The two components - the ligand and the lytic peptide - may optionally be administered as a fusion peptide, or they may be administered separately, with the ligand administered slightly before the lytic peptide, to activate cells with receptors for the ligand, and thereby make those cells susceptible to lysis by the lytic peptide. The compounds may be used in gene therapy to treat malignant or non-malignant tumors, and other diseases caused by clones or populations of "normal" host cells bearing specific receptors (such as lymphocytes), because genes encoding a lytic peptide or encoding a lytic peptide/peptide hormone fusion may readily be inserted into hematopoietic stem cells or myeloid precursor cells.
