Researchers at the University of California San Diego used natural killer cells in a study as immunotherapeutic agents. They found that the natural killer cells are effective in ridding tumor cells from the body.
Immunotherapy for cancer treatment is rapidly emerging, and many studies are aimed at increasing the safety and efficacy of anti-tumor immunotherapy. Although T cells have been extensively studied, more research is being conducted on the use of natural killer (NK) cells as immunotherapeutic agents. NK cells are lymphocytes of the immune system capable of attacking and killing virus-infected and tumor cells. NK cells can lyse tumor cells without prior activation, but the potency of this effect limits its clinical use.
