Abstract:
PURPOSE: A method for measuring the activity of natural killer cells (NK cells) is provided to test with the same accuracy as a standard method (^51Cr release method) using a luciferase expression cell line without radioactive isotopes. CONSTITUTION: A method for measuring the activity of NK cells comprises the steps of: mixing a measuring sample containing the NK cells and a target sample containing a luciferase expression cell line; adding luciferin to the mixture of the measuring sample and the target sample; and measuring light generated while luciferin turns into oxyluciferin by the action of luciferase. The luciferase expression cell line is prepared by inserting luciferase genes into one cell line among K562, ES-8, HL-60, Daudi, and ARH77.
Abstract:
PURPOSE: A method for enhancing dendritic cell migration and ability of killing cytotoxic T cells is provided to improve migration of cendritic cells into a secondary lymphoid organ. CONSTITUTION: A composition for enhancing migration of dendritic cells contains chemokines including CCL21, CCL19, or mixture thereof. An active ingredient relates to migration of a secondary lymphoid organ by 10-250 ng/mL. A method for enhancing cell killing ability of cytotoxic T cells comprises a step of adding chemokine to monocytes during differenetion of immature dendritic cells into dendritic cells and culturing the dendritic cells.
Abstract:
PURPOSE: A composition for inducing maturation of dendritic cells is provided to use as a therapeutic agent for tumor. CONSTITUTION: A composition for inducing maturation of dendritic cells contains bacteria flagellin, TNF-alpha, and interferone as active ingredients. A method for inducing maturation of immature dendritic cells comprises: a step of differentiating monocytes isolated from blood to immature dendritic cells; and a step of treating with bacteria flagellin, TNF-alpha and interferone to the immature dendtritic cells.
Abstract:
PURPOSE: A novel tumor antigen protein AGR2 and tumor antigenic peptide thereof are provided to induce tumor-specific cytotoxicity immune response. CONSTITUTION: A cellular immunotherapeutic agent composition for preventing or treating colorectal cancer comprises dendritic cells having human AGR2(anterior gradient-2) tumor antigenic peptide with an amino sequences of sequence number 6 or 12 or AGR2-specific cytotoxic T lymphocytes which is secreted from the dendritic cells as active ingredients. A method for manufacturing cellular immunotherapeutic agent composition for treating or preventing colorectal cancer comprises: a step of loading the human AGR2 tumor antigenic peptide; and a step of co-culturing the loaded dendritic cells and T lymphocytes.
Abstract:
PURPOSE: A method for enhancing cytotoxicity of cytotoxic T cells is provided to enhance mobility of dendritic cells to a second lymph organ and to induce maturation of novel dendritic cells. CONSTITUTION: A method for enhancing cytotoxicity of cytotoxic T cells comrises: a step of differentiating monocytes isolated from blood into immature dendritic cells; a step of treating antiviral cytokines, TLR activator, or mixture thereof to the immature dendritic cells to culture the immature dendritic cells; a step of treating a composition for enhancing mobility of dendritic cells to the immature dendritic cells to maturing the immature dendritic cells; and a step of adding IP-10(interferon-gamma inducible protein-10) to the matured dendritic cells.
Abstract:
PURPOSE: Matured dendritic cells by uncarinic acid C are provided to enhance the differentiation of nave T cells to Th1 cells and to induce specific reaction. CONSTITUTION: A mutured dendritic cell is obtained by adding uncarinic acid C to immature dendritic cells and culturing. A composition for immunotherapy contains dendritic cells, T cells differentiated therefrom, or cytokine produced thereby. The uncarinic acid C is isolated from Uncaria rhynchophylla. A method for producing the matured dendritic cells comprises: a step of adding uncarinic acid C to immature dendritic cells by intravenous or hypodermic infection, and a step of culturing the dendritic cells.
