  • Publication number: 20180036326
    Abstract: The present invention provides novel processes for regulating immune responses in mammalian subjects, e.g., humans, afflicted with diseases such as cancers, infections, e.g., viral infections, bacterial infections, or immune dysfunctions, especially auto-immune disorders, e.g., diabetes, Crohn's disease, rheumatoid arthritis, arteriosclerosis and ulcerative colitis. More particularly, this invention relates to generating elevated levels of an intermediary metabolite, e.g., lipids or conjugated biomolecules, e.g., glycolipids, lipoproteins and glycoproteins other than antibodies, cytokines or hormones. Treatment can be carried by introduction of the intermediary metabolite into the afflicted subject or by a reagent that when administered leads to elevated levels. The treatment regimen can be in vivo or ex vivo.

  • Patent number: 8846893
    Abstract: The present invention provides an array of compositions useful for effecting and/or exhibiting changes in biological functioning and processing within cells and in biological systems containing such cells. In effect, these compositions combine chemical modifications and/or ligand additions with biological functions. The chemical modifications and/or ligand additions provide additional characteristics to the compositions without interfering substantially with their biological function. Such additional characteristics include nuclease resistance, targeting specific cells or specific cell receptors localizing to specific sites within cells and augmenting interactions between the compositions and target cells of interest as well as decreasing such interactions when desired. Also provided by the present invention are processes and kits.

  • Publication number: 20110097791
    Abstract: This invention provides inter alia an in vitro process for producing multiple specific nucleic acid copies in which the copies are produced under isostatic conditions, e.g., temperature, buffer and ionic strength, and independently of any requirement for introducing an intermediate structure for producing the copies. In other aspects, the invention provides in vitro processes for producing multiple specific nucleic acid copies in which the products are substantially free of any primer-coded sequences, such sequences having been substantially or all removed from the product to regenerate a primer binding site, thereby allowing new priming events to occur and multiple nucleic acid copies to be produced. This invention further provides a promoter-independent non-naturally occurring nucleic acid construct that produces a nucleic acid copy or copies without using or relying on any gene product that may be coded by the nucleic acid construct.

  • Publication number: 20100021500
    Abstract: This invention provides novel processes for therapeutic applications, including the treatment of subjects carrying infectious agents or having impaired autoimmunity or impaired immune condition. The therapeutic applications disclosed herein are also directed at the treatment of cancerous subjects with malignant tumors containing cancerous cells or malignant or cancerous cells. Vaccination processes for preventing infections in subjects are also provided. The novel processes comprise introducing into or adminstering to a subject one or more antigens, or trained or adopted immune cells. These antigens or immune cells are capable of establishing or increasing at least one first specific immune response and decreasing at least one second specific immune response. Such responses include components, such as cellular immune reaction elements, humoral immune reaction elements and cytokines, the latter also encompassing interferons and lymphokines. Useful compositions are also provided by this invention.

  • Publication number: 20040023909
    Abstract: Novel immune modulating processes are provided in which the imunological state of a subject including mature subjects, mammals and humans, are down regulated in a selective manner, and as a subset in a dominant manner. The novel immunological state termed SIDR for selective immune down regulation is usefully applied to the immunological modulation or regulation of gene delivery components, artificially expressed genes, gene delivery systems and expression products of artificially introduced genes by such delivery systems, and infectious agents. SIDR is also useful when combined with other immune modulating treatments such as general immune suppression and anti-apoptosis. SIDR may also be used to selectively down regulate the immune response system of a subject to a wide variety of noncellular immunogenic components and to native antigens. Other processes for producing immune suppression by administering macromolecules or compounds to a subject so as to obtain or effect SIDR are also provided.
