Turbocharging the body's natural killer cells to defeat cancer

Natural Killer (NK) cells have long been the soldiers of the immune system that prevents the growth and spread of cancers, and subduing this army of cells is one of the key ways that tumours take hold. Researchers have discovered a protein that prevents NK cells from doing their job fighting cancer. Importantly the study reveals that blocking this protein turbo charges the immune system to fight off the cancer cells.
