20100235932 | ANIMAL MODELS CARRYING TUMORS EXPRESSING HUMAN LIVER CANCER-SPECIFIC ANTIGEN AND METHOD FOR ANALYZING PREVENTION AND TREATMENT EFFICACY OF DENDRITIC CELLS-DERIVED IMMUNOTHERAPEUTICS USING THE ABOVE - The present invention relates to a method for analyzing the prevention and treatment efficacy of a dendritic cell-derived immunotherapeutic for liver cancer using an animal model carrying tumors expressing a human liver cancer-specific antigen, which comprises the steps of: (a) (a1) administering to a normal animal other than human dendritic cells to be analyzed, or (a1) administering to a normal animal other than human a cancer cell line expressing the human liver cancer-specific antigen to induce cancer in the normal animal; (b) (b1) administering to the animal the cancer cell line expressing the human liver cancer-specific antigen to induce cancer in the animal when the step (a1) is performed in the step (a), or (b1) administering to the animal with cancer dendritic cells to be analyzed when the step (a1) is performed in the step (a); and (c) determining the prevention and treatment efficacy of the dendritic cells as immunotherapeutics for liver cancer by measuring the formation or growth of cancer cells originated from the cancer cell line in the animal. | 09-16-2010 |
20100215624 | Pharmaceutical Compositions for Treating Rheumatoid Arthritis Comprising Semi-Mature Dendritic Cell - The present invention relates to a pharmaceutical composition for treating rheumatoid arthritis, which comprises (a) a pharmaceutically effective amount of a semi-mature dendritic cell; and (b) a pharmaceutically acceptable carrier. The semi-mature dendritic cell of this invention has a safe and remarkably improved potential to treat or prevent rheumatoid arthritis through the activity of the suppression of auto-immune responses. | 08-26-2010 |
20100055076 | Mesenchymal stem cell-mediated autologous dendritic cells with increased immunosuppression - A method for preparing dendritic cells which have an enhanced potential to suppress immune responses, method for suppressing immune response by comprising administering them, dendritic cells carrying a potential to suppress immune responses, and a pharmaceutical composition comprising the dendritic cells capable of inducing immunosuppressive responses. The present dendritic cells having an enhanced potential to suppress immune responses can be utilized for treating or preventing various diseases or disorders through the suppression of immune responses. In addition, the enhanced immunotolerance potential of the dendritic cells ensures the cells to be effectively used as an immunosuppressive agent. | 03-04-2010 |
20090293138 | ANIMAL MODELS CARRYING TUMORS EXPRESSING HUMAN PROSTATE CANCER-SPECIFIC ANTIGEN AND METHOD FOR ANALYZING PREVENTION AND TREATMENT EFFICACY OF DENDRITIC CELLS-DERIVED IMMUNOTHERAPEUTICS - A method for analyzing the prevention and treatment efficacy of a dendritic cell-derived immunotherapeutic for prostate cancer using an animal model carrying tumors expressing a human prostate cancer-specific antigen includes either administering to a normal non-human animal dendritic cells to be analyzed, or administering to a normal non-human animal a cancer cell line expressing the human prostate cancer-specific antigen to induce cancer in the normal non-human animal; administering to the animal the cancer cell line expressing the human prostate cancer-specific antigen to induce cancer in the animal when the dendritic cell administering step was performed, or administering to the animal with cancer dendritic cells to be analyzed when the human prostate cancer-specific antigen expressing cell line administering step was performed; and determining the prevention and treatment efficacy of the dendritic cells as immunotherapeutics for prostate cancer by measuring the formation or growth of cancer cells originated from the cancer cell line in the animal. | 11-26-2009 |
20090029387 | METHOD FOR EFFECTIVELY MEASURING THE ACTIVITY OF CYTOTOXIC T LYMPHOCYTES IN HUMAN AND OUT-BRED ANIMALS - A method for measuring the activity of cytotoxic T lymphocytes (CTLs) includes preparing peripheral blood mononuclear cells (PBMCs) from blood of an animal; preparing mature dendritic cells by isolating monocytes from the PBMCs, differentiating the monocytes into dendritic cells for presenting an antigen molecule and pulsing dendritic cells with the antigen molecule to obtain the mature dendritic cells; preparing the CTLs as an effector cell by stimulating the PBMCs with the mature dendritic cells to activate and amplify the CTLs; preparing target cells by pulsing the PBMCs, monocytes or B cells with a cytoplasmic transduction peptide (CTP)-antigen complex generated by linking the antigen molecule of step (b) to the CTP; treating the target cells with the effector cells; and analyzing the lysis of the target cells. In addition, a kit for measuring the activity of cytotoxic T lymphocytes is provided. | 01-29-2009 |
