Animation of cytotoxic T cells attacking lung cancer cells. T cells, or T lymphocytes, are a type of white blood cell that recognise a specific site (antigen) on the surface of cancer cells or pathogens and bind to it. Some T lymphocytes then signal for other immune system cells to eliminate the cell. Cytotoxic T lymphocytes eliminate the cell themselves. They attach to the target cell and secrete the protein perforin, which pierces the cell membrane, allowing cytotoxin granules to enter the cell. The cytotoxin granules expel granzymes which promote cell apoptosis (programmed cell death).

The protrusions from the cell at centre are typical of a dying cell. Macrophages are cells of the body's immune system. They phagocytose (engulf) and destroy pathogens, dead cells and cellular debris. Frame width: 126.52 micrometres.

He's known the world over for his boxing talents...but now, Hector "Macho" Camacho is gaining fame of a different sort...getting in trouble with the law. Camacho was arrested last night by police on suspicion of driving under the influences. He is now out of jail on 5-thousands dollar bond. Camacho, who is a former W-B-C super featherweight and lightweight champion, has had several run ins with the law in recent years. In 1995 he was arrested for allegedly battering a pregnant woman...and earlier this year, his wife filed a restraining order against him.
