Caption

Cancer attacked by killer cells. Coloured 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 & tumour cells. On contact with the surface of a tumour 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.
