Identifying Anticancer Immune Cells

Scientists have long known that the human immune system has a method for detecting and destroying precancerous cells. But finding the cells behind this defense mechanism in order to study and perhaps even mimic them has proved quite the challenge. Since the malignant precancerous cells are eradicated before we even know they exist, identifying the cells that killed them seemed nearly impossible. Now European researchers have built a microfluidic biosensor that traps single immune cells together with single tumor cells, allowing the researchers to pick the most potent of these cancer killers out of a crowded field.
