  • Patent number: 8062860
    Abstract: The present invention relates a method for the enumeration of in vivo gene mutation. The method utilizes differential staining of GPI-anchor deficient erythrocyte populations to distinguish between wild-type and pig-a gene mutants.

Immune cell development and function can be modulated by delivery of microRNA-146 (miR-146) or antisense miR-146 to target immune cells or precursor cells. For example, in some embodiments, activity and/or proliferation of certain immune cells is regulated by administering miR-146 oligonucleotides or anti-miR-146 oligonucleotides. In other embodiments, pro-inflammatory cytokine expression in immune cells is regulated by administering a miR-146 oligonucleotide or anti-miR-146.

  • Publication number: 20100058488
    Abstract: The present inventors discovered that knockout mice whose S1-5 gene function is lost develop age-related diseases or symptoms. In such knockout mice, bone mineral content, bone mineral density, and bone strength were found to be decreased, and the number of osteoclasts in bone tissues was found to be increased. Analysis of osteoclast-forming ability using bone marrow cells derived from the knockout mice revealed that osteoclast-forming ability is enhanced and osteoclasts are larger in the knockout mice than in wildtype mice. When purified S1-5 protein was added to this in vitro system, osteoclast-forming ability was inhibited. Furthermore, administration of purified S1-5 protein to osteoporotic model mice showed that this protein has the effect of improving osteoporosis. The above findings demonstrate that S1-5 protein is useful for treating and preventing age-related diseases such as osteoporosis.

  • Publication number: 20080287348
    Abstract: The present invention relates to a soluble hybrid protein, comprising at least a first polypeptide sequence derived from a prion protein PrPc that is capable of binding a protein responsible for transmissible spongiform encephalitis (PrPSc), and a second polypeptide sequence (tag), wherein said hybrid protein does not comprise a functional membrane anchor moiety. Also, the present invention is directed to the use of said hybrid proteins for the diagnosis of transmissible spongiform encephalopathies. In addition, the present invention relates to the use of said hybrid protein, a nucleic acid encoding said hybrid protein, a vector, and/or a host cell comprising a nucleic acid encoding said hybrid protein for the preparation of a medicament for the prevention or treatment of transmissible spongiform encephalopathies (TSEs).

  • Patent number: 7442547
    Abstract: The present invention is based on the discovery that in response to different stimuli, dendritic cells initiate various immune responses by producing different transcription profiles, e.g., IL-2 production by dendritic cells in response to a microbial stimulus. The present invention provides methods of making libraries of gene expression profiles and libraries made thereof corresponding to dendritic cell maturation in response to a microbial stimulation. The present invention provides methods for activating lymphocytes or immune responses and methods for producing Il-2 in dendritic cells or preparing dendritic cells for cell-based therapy. The present invention also provides methods and systems for screening agents affecting dendritic cell maturation. In addition, it is the discovery of the present invention that dendritic cells are targets for immunosuppressive virus infections.

  • Patent number: 7371921
    Abstract: An object of the present invention is to provide a non-human animal model unresponsive to a mycoplasma-derived lipoprotein/lipopeptide, and a method for screening an inhibitor or a promoter for a response to a mycoplasma-derived lipoprotein with the use of the non-human animal model. A non-human animal model whose function of a gene that encodes a protein such as TLR6 that specifically recognizes a mycoplasma-derived lipoprotein is deficient on its chromosome, for example, a TLR6 knockout mouse, is generated. With the use of the non-human animal model unresponsive to a mycoplasma-derived lipoprotein or an immune cell such as a macrophage derived from the non-human animal model, a subject material and a mycoplasma-derived lipoprotein, a response to a mycoplasma-derived lipoprotein in the non-human animal model or the immune cell is measured/evaluated, and then an inhibitor or a promoter for a response to that is screened.

  • Patent number: 7364900
    Abstract: Methods of inducing differentiation of mammalian bone marrow stromal cells into cells of multiple embryonic lineages by contacting marrow stromal cells with precursor differentiation-inducing compounds followed by contacting the partially differentiated precursor cells with specific cell type differentiation-inducing compounds. In one embodiment, the MSC derived precursor cell cultures comprise cells, at least some of which simultaneously express markers that are characteristic of endodermal and ectodermal cell types. In another embodiment, the differentiated cells are insulin-secreting pancreatic islet cells. Precursor differentiation-inducing compounds of the invention include anti-oxidants such as, but not limited to, beta-mercaptoethanol, dimethylsulfoxide, butylated hydroxyanisole, butylated hydroxytoluene, ascorbic acid, dimethylfumarate, and n-acetylcysteine.

  • Patent number: 7358087
    Abstract: Molecular adjuvants are disclosed comprising an antigen presenting cell-targeting ligand linked to an immunogen. In particular, these molecular adjuvants are employed in compositions designed to deliver the specific immunogen to antigen presenting cells and simultaneously deliver signals to those cells that produce the desired immune response. Methods are also disclosed for delivery of these molecular adjuvants to patients, resulting in the transduction of activating signals to the targeted antigen presenting cell, thereby enhancing the immune response to the co-delivered immunogen.
