Jurkat cells are an immortalized line of human T lymphocyte cells that are used to study acute T cell leukemia, T cell signaling, and the expression of various chemokine receptors susceptible to viral entry, particularly HIV. Jurkat cells can produce interleukin 2, and are used in research involving the susceptibility of cancers to drugs and radiation.
Method for the induction and expansion of natural killer cells derived from peripheral blood mononuclear cells
ActiveUS12674138B2Viral transformationPeripheral blood mononuclear cell
The present invention relates to a method for inducing and expanding natural killer cells derived from peripheral blood mononuclear cells, which comprises co-culturing, as feeder cells, irradiated Jurkat cells and irradiated Epstein-Barr virus transformed lymphocyte continuous line (EBV-LCL) cells in the presence of cytokines, along with peripheral blood mononuclear cells. According to the present invention, a large quantity of natural killer cells can be induced and proliferated from a small quantity of peripheral blood mononuclear cells even without the use of high-cost equipment or various kinds of expensive cytokines, thereby making it possible to significantly improve the efficiency and efficacy of the prevention and treatment of cancer using the natural killer cells.
