  • Publication number: 20120309691
    Abstract: Nanoconstructs having three components: (1) biodegradable nanopolymers and nanoparticles, (2) immunodrugs such as CpG, and a (3) tumor binding device, which are actively targeted to tumor cells such as melanoma cells through receptor-mediated uptake and methods of using the same are described. Antitumor immunity is further enhanced by combination of PG-CpG nanoconstructs with agonists of positive costimulatory signals and inhibitors of negative immune regulatory signals.

  • Patent number: 8211422
    Abstract: Chimeric receptor genes suitable for endowing lymphocytes with antibody-type specificity include a first gene segment encoding a single-chain Fv domain of a specific antibody and a second gene segment encoding all or part of the transmembrane and cytoplasmic domains, and optionally the extracellular domain, of an immune cell-triggering molecule. The chimeric receptor gene, when transfected to immune cells, expresses the antibody-recognition site and the immune cell-triggering moiety into one continuous chain. The transformed lymphocytes are useful in therapeutic treatment methods.

  • Publication number: 20100158881
    Abstract: The present invention relates to preventive, therapeutic, and diagnostic compositions and methods employing lymphocytes having T-cell receptors and chimeric receptors. In particular, the invention relates to pre-selected dual-specificity lymphocytes having endogenous T-cell receptors and chimeric T-cell receptors that recognize a strong antigen and tumor associated antigens where the pre-selected population of adoptively transferred lymphocytes is activated by in vivo immunization, thereby increasing the effectiveness of adoptive immunotherapy.

  • Publication number: 20100135958
    Abstract: A method of treating and/or preventing cancer in a subject, preferably mammalian, more preferably human, by administering in an effective amount IL-21 polypeptide, polynucleotide, vector comprising an IL-21 nucleic acid sequence encoding an IL-21 polypeptide, variants, and fragments thereof, thereby acting as an anti-cancer agent by reducing, ameliorating, and/or eliminating the cancer; and a method of treating and/or preventing cancer in a subject by co-administering the IL-21 polypeptide, polynucleotide, IL-21 vector, variant, and fragments thereof, with an immunotherapeutic and/or chemotherapeutic agent for the treatment and/or prevention of cancer in a subject.

  • Publication number: 20090263365
    Abstract: Recombinant dendritic cells are made by transforming a stem cell and differentiating the stem cell into a dendritic cell. The resulting dendritic cell is an antigen presenting cell which activates T cells against MHC class I-antigen targets. Kits, assays and therapeutics are based upon the activation of T cells by the recombinant dendritic cell. Cancer, viral infections and parasitic infections are all ameliorated by the recombinant dendritic cells, or corresponding activated T cells. Therapeutic compositions and pharmaceutical compositions are provided.
