Body’s ‘serial killers’ captured on film destroying cancer cells
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.
In a study published today in the journal Immunity, a collaboration of researchers from the UK and the USA, led by Professor Gillian Griffiths at the University of Cambridge, 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.
“Inside all of us lurks an army of serial killers whose primary function is to kill again and again,” explains Professor Griffiths, Director of the Cambridge Institute for Medical Research. “These cells patrol our bodies, identifying and destroying virally infected and cancer cells and they do so with remarkable precision and efficiency.”
