Ever wondered how our T lymphocytes hunt down and kill cancer cells? This Cambridge University video shows how our cytotoxic T cells (the ones with a CD8 marker and hence called CD8+ T cells ), check whether a cell in the blood is cancerous or infected and if so destroys it. Unfortunately for us, our CLL B-cells put these T cells to sleep so that they won't attack our CLL and that's why we're thought to be more prone to secondary cancers...
