T lymphocyte. Coloured scanning electron micrograph (SEM) of a T lymphocyte white blood cell, or T cell, surrounded by fibrin strands. Like all white blood cells, T cells are components of the body's immune system. They recognise a specific site on the surface of pathogens or foreign objects (antigens) and bind to it. Some T lymphocytes then signal for other immune system cells to eliminate the cell. Magnification: x12,300 when printed at 10 centimetres wide.
