What are natural killer cells?

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.
