Body’s ‘serial killers’ captured on film destroying cancer cells

Cambridge: A dramatic video has captured the behaviour of cytotoxic T cells – the body’s ‘serial killers’ – as they hunt down and eliminate cancer cells before moving on to their next target. Inside all of us lurks an army of serial killers whose primary function is to kill again and again. A study published in the journal Immunity describe how specialised members of our white blood cells known as cytotoxic T cells destroy tumour cells and virally-infected cells. Using state-of-the-art imaging techniques, the research team, with funding from the Wellcome Trust, has captured the process on film.
