NK cell immunotherapy in China, Japan and South Korea.
What are NK cells?
NK cells are called natural killer cells (NK), which are important immune cells in the body along with T cells and B cells. NK cells are our body's first immune barrier; they have a natural ability to recognize "enemies" such as viruses, bacteria, cancer cells, etc. that the body encounters.
NK cells usually patrol the blood vessels of the human body like policemen. Once they find abnormal cells, they can immediately identify them and destroy them.
