Cancer’s toughest strongholds – solid tumours like those in the lung, liver, and pancreas – have long outwitted modern medicine. But what if the key to defeating them was already inside us – just hidden hero in plain sight? Using powerful AI to peer into cancer at single-cell resolution, CUHK researchers have discovered a previously unknown immune cell that can naturally hunt down and destroy solid tumours from within – a feat where conventional treatments fail. Even more remarkably, the team has developed a way to manufacture these “Super” immune cells from a patient’s blood, potentially opening the door to a brave new world of safe, fast-acting, cancer-bashing immunotherapy.
