Natural Killer Cells (NK Cells)

The immune system consists of many parts that work together to defend the body against invaders internally and externally.

NK cells are the primary effector cell of innate immunity; the first responders of the immune system. They interact with signals from other cells (activating and inhibitory).

NK cells are unique and play pivotal functions in cancer immune surveillance. NK cells can eliminate a variety of abnormal or stressed cells without prior sensitization, and even preferentially kill cancer or tumor cells without harming the healthy cells.

Nk can prevent cancer while boosting immunity against viral infection.
