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.
