NK CELLS

NK CELLS

NATURAL KILLER CELLS

That have quicker immune reactions than our inherent immune system. Unlike regular immune cells, NK cells can identify and kill tumorous cells or cells infected by viruses. Without them, our lives would last much shorter. (MURRAY, Patrick R.; ROSENTHAL, Ken S.; PFALLER, Michael A.. Medical Microbiology, Fifth edition. [s.l.] : Elsevier, 2005)

NK cells are Usain Bolt among immune system cells.
