  • Publication number: 20070270337
    Abstract: [Problems] The present invention provides a pharmaceutical composition for preventing or treating Th1-mediated immune diseases. [Means for Solving] There is obtained a pharmaceutical composition provided for prevention or treatment of Th1-mediated immune diseases, which comprises as an active ingredient a substance capable of acting on the NP receptor GC-A expressed on dendritic cells to enhance cGMP production and thereby driving T cells to differentiate into Th2-type cells by regulating cytokine production from dendritic cells.

  • Publication number: 20070155013
    Abstract: A novel growing method is provided for pluripotent stem cells such as ES cells. The method of the invention is a pluripotent stem cell growing method and gene transfer method in which pluripotent stem cells are cultured under conditions that maintain their undifferentiated state and pluripotency, the method being characterized by using a liquid medium and a culturing vessel having immobilized or coated on a substrate solid phase surface a molecule which is adhesive to the pluripotent stem cells in a fixed concentration, to grow the pluripotent stem cells in a dispersed state while maintaining their undifferentiated state and pluripotency, without using feeder cells, or to transfer and express a gene therein.

  • Publication number: 20070009496
    Abstract: The proliferation of cardiomyocytes is induced by expressing cyclin and CDK in the cardiomyocytes, and by suppressing the function or action of a Cip/Kip family protein or inhibiting the production of a Cip/Kip family protein. Among the Cip/Kip family proteins, it is preferable to suppress the function of p27KiP1 or inhibiting the production thereof. As a recombinant vector to be used therefor, there is provided a vector comprising: (1) a cyclin gene; (2) a cyclin-dependent kinase gene; and (3) one or a plurality selected from the group consisting of a gene encoding a factor that inhibits the function or action of a Cip/Kip family protein and a nucleic acid sequence that inhibits the production of Cip/Kip family protein.

  • Patent number: 7138489
    Abstract: The present invention is a method for producing a peptide or a protein in which a side chain contains a modified amino acid residue, which comprises chemically producing a peptide fragment containing an amino acid residue having a modified side chain using an weak acid-cleavable resin, producing a peptide fragment containing no amino acid residue having a modified side chain using a genetic recombination method or/and an enzymatic method, and condensing the resulting two kinds of peptide fragments and, according to the present invention, a peptide or a protein containing modification such as acylation, glycosylation and phosphorylation can be obtained effectively and at high quality.

  • Patent number: 7087248
    Abstract: A medical component comprising a human parathyroid hormone peptide or its derivative, and acetic acid contained at a concentration less than its chemical equivalent with respect to the human parathyroid hormone peptide or to its derivative. Since in the medical component acetic acid, which is present as a salt of or attached to the peptide or its derivative, has been reduced to an amount less than chemical equivalent with respect to the human parathyroid hormone peptide or its derivative, a medical component, which is highly stable and will ensure an excellent use feeling when introduced into a pharmaceutical composition, is obtained.
