Scientists discover the engine that powers cancer-killing NK cells

Scientists have just discovered how the engine that powers cancer-killing cells functions. Crucially, their research also highlights how that engine is fuelled and that cholesterol-like molecules, called oxysterols, act as a “cut-off” switch making it hard for our ‘Natural Killer’ cells to win the war against cancer. The scientists, led […]
