New Zealand researchers makes ’natural born killer‘ cell discovery

An unexpected role for a white blood cell called the Natural Killer (NK) cell — a critical cell for ridding the body of infection and cancer, has been discovered. The NK cell is a ‚vigilante‘ killer — a white blood cell that destroys invaders and cancer cells through a process of ‚identity card‘ checking. The researchers‘ new work shows that violent vigilante NK cells act as helper cells to start up the immune response. (Mehr in: Cancer News — ScienceDaily)
