  • Patent number: 8445275
    Abstract: A method of inducing dendritic cell (DC) development by administering Macrophage-Colony Stimulating Factor (M-CSF) is provided. M-CSF induces DCs to differentiate into Subtypes, for example plasmacytoid DCs and conventional DCs. Said differentiation is independent of Fms-like-Tyrosine-Kinase 3-Ligand (FL) and/or Granulocyte-Macrophage-Colony Stimulating Factor (GM-CSF). Induction with M-CSF can be achieved in vitro from hematopoietic precursors, such as bone marrow cells, or in vivo. In vitro, M-CSF-derived DCs can be used to produce cytokines and to stimulate other immune response cells. M-CSF can also be used to induce precursor cells removed from an animal to develop into DCs. In addition, these isolated DCs can be exposed to antigens to stimulate a specific immune response when reintroduced into the animal. Treatments for Cancers, such as Acute Myeloid Leukemia, and autoimmune diseases such as Systemic Lupus Erythematosus, are also provided in the invention.

  • Patent number: 8354275
    Abstract: A method of inducing dendritic cell (DC) development by administering Macrophage-Colony Stimulating Factor is provided. M-CSF induces DCs to differentiate into subtypes, for example plasmacytoid DCs and conventional DCs. Induction with M-CSF can be achieved in vitro from hematopoietic precursors, such as bone marrow cells, or in vivo. In vitro, M-CSF-derived DCs can be used to produce cytokines and to stimulate other immune response cells. M-CSF can also be used to induce precursor cells removed from an animal to develop into DCs. In addition, these isolated DCs can be exposed to antigens to stimulate a specific immune response when reintroduced into the animal. Treatments for cancers, such as Acute Myeloid Leukemia, and autoimmune diseases such as Systemic Lupus Erythematosus, are also provided in the invention.

  • Patent number: 8318153
    Abstract: A method immunizing an individual that minimizes the amount of antigen or attenuated organism needed and the number of doses and clinic visits required, while making possible polyvalent simultaneous immunizations. The method comprises the steps of obtaining a sample of blood. Exposing at least a portion of this sample to at least one immunogenic antigen, attenuant or other immunogen. Incubating the exposed sample under specified optimal conditions and introducing this exposed sample into the individual to effect immunization thereof. The method of the invention also provides a method of delivery of materials, other than antigens, throughout an individual's body such as therapeutic drugs, virus vectors, genes, DNA, RNA, isotopes, and other therapeutic substances. A method for the delivery of treatment material to an individual is also provided by this method.
