Cancer attacked by Natural Killer Cells

IMAGE NUMBER: S6641 LICENSE: RIGHTS MANAGED

Cancer attacked by killer cells. Colored Scanning Electron Micrograph (SEM) of two human natural killer (NK) cells attacking a cancer cell. The NK cells are yellow with numerous long fluid projections which are beginning to flow around the red cancer cell. Natural killer cells are a type of white blood cell known as T-lymphocytes. These have the ability to destroy virus-infected cells & tumor cells. On contact with the surface of a tumor cell, the NK cell recognizes certain proteins called antigens which activate its cell-killing mechanism. The NK cell then binds to & destroys the cancer cell using toxic chemicals. Magnification: x2,800 at 6x6cm size.
