Natural Killer Cells (Overview)

Natural killer (nk) lymphocytes have the ability to kill various abnormal cells such as those damaged by trauma, aging, viruses and possibly cancer cells. Nk cells do not need to be stimulated ("primed") by previous recognition of the cell, antibodies or lymphokines; they are stimulated by interferon.

What r natural killer cells?

Cells that kill.: These are cells of the immune system that kill other cells that represent a danger to the body, like virally infected cellls and cancer cells. They have a natural ability to recognize stressed cells and can kill these without need of antibody or major histocompatability complex alteration to prime them, hence their name. Thus, they can present a much faster response than other immune cells. ...Read more

Immune cells: Natural killer cells are immune effector cells that are efficient in killing virus infected cells. They can be divided into 2 sets: CD56bright (produce antiviral agents and help a subset of T cells) and CD56dim (fully mature, can destroy antibody targeted cells). There is a 3rd, dysfunctional subset that has been described in HIV. ...Read more
