Enhancing immune defenses: Researchers unveil the secrets of specialized T cells to conquer tumors

Our immune system has an ingenious trick up its sleeve. It remembers past foes, stopping potential sickness in its tracks through a phenomenon known as immunological memory. This is thanks to specialized cells—tissue-resident memory T cells—which reside in vital organs like the small intestine, lungs and other areas. Consider them as frontline guards, stationed exactly where trouble could strike. The endurance of these cells is extraordinary, protecting us from infections we fought decades ago.
