  • Patent number: 9474771
    Abstract: The invention relates to methods and compositions for causing the selective targeting and killing of tumor cells. Through ex vivo gene therapy protocols tumor cells are engineered to express an ?(1,3)galactosyl epitope. The cells are then irradiated or otherwise killed and administered to a patient. The ?-galactosyl epitope causes opsonization of the tumor cell enhancing uptake of the opsonized tumor cell by antigen presenting cells which results in enhanced tumor specific antigen presentation. The animal's immune system thus is stimulated to produce tumor specific cytotoxic cells and antibodies which will attack and kill tumor cells present in the animal.

  • Publication number: 20130149331
    Abstract: The present invention provides an immunogenic composition comprising a T-cell antigen in association with a rhamnose monosaccharide and/or Forssman disaccharide, and corresponding methods for inducing immune response. The T-cell antigen may be for example, a tumor vaccine, such as a tumor cell or one or more tumor antigens. The invention takes advantage of the naturally high titers of anti-Rhamnose and/or anti-Forssman disaccharide in humans to target vaccine compositions to antigen presenting cells.

  • Patent number: 7125549
    Abstract: The invention includes a viral vector method and composition comprising transcomplementary replication incompetent viral vectors, preferably adenoviral vectors, which are cotransformed to a recipient cell. The two vectors complement each other and thus allow viral replication, in a synergistic combination which enhances both gene delivery and gene expression of genetic sequences contained within the vector.

  • Patent number: 7078179
    Abstract: A method is described for the rapid identification and isolation of cells based on the presence or absence of an ectopically-expressed N-acetyllactosaminide 3-? Galactosyltransferase (?GT) enzyme for the production of ?Galactosyl-(1,3)Galactosyl (?Gal) epitopes on the surface of ?Gal-negative cells. These cells which are genetically modified to express the ?GT enzyme and ?Gal epitopes on glycosylated lipids and proteins of the cell surface are then labeled via an antibody composition which recognizes and binds the ?Gal epitopes on the cell surface. Cells labeled with the anti-?Gal antibody can be isolated by sorting via fluorescence activated cell sorting (FACS), or by magnetic panning techniques. This method is suitable for the rapid positive or negative selection of ?Gal-positive cells from within a population of ?Gal-negative cells without the need to expose cells to antibiotics for any period of time.

  • Patent number: 7005126
    Abstract: A method for treating tumors. Through infusion or xenotransplantation of xenogeneic cells, such as infusion of murine cells into the peritoneal cavity of humans, a hyperacute rejection response to the cells is induced. This in turn creates a bystander effect to the tumor. This effect creates tumor regression. This treatment can be used alone or in conjunction with gene therapy or chemotherapy treatments.

  • Patent number: 6541197
    Abstract: The present invention describes an efficient retroviral or viral based method that allows easy and quick identification of gene transfer in living, transduced mammalian cells. Retroviral and viral vector producer cells were generated containing a gene for an improved humanized red-shifted, Green Fluorescent Protein (hRGFP) which increases the resulting fluorescence yield after excitation. This humanized, red-shifted GFP (hRGFP) gene was cloned into several vectors and transfected into various packaging cell lines to produce vibrant green fluorescence after excitation with blue light at 450-490 nm. These vectors represent a substantial advance over currently available gene transfer marking systems or wild-type GFP marker systems none of which have been stably transfected into cells.

  • Patent number: 6342217
    Abstract: The present invention pertains to combination radio therapy of tumors and more specifically to pharmaceutical compositions, and methods of treatment by gene therapy designed to sensitize tumors in animals, notably humans, and render them more susceptible to radiation, thus significantly reducing the amount of radiation required to kill neoplastic cells while at the same time making the radiation far more tissue specific to the tumor site.
