Coloured SEM of killer cell attacking cancer cell
Cancer attacked by killer cell. Coloured Scanning Electron Micrograph (SEM) of a human Natural Killer (NK) cell attacking a cancer cell. The NK cell is yellow with numerous long fluid- projections which are beginning to flow around the large orange 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 toxins. Magnification: x3, 850 at 6x6cm size.
