Turbocharging the body's natural killer cells to defeat cancer

29-Aug-2019

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. Australian researchers have discovered a protein found in humans that prevents NK cells from ...
