T cells are usually very good at eliminating diseased cells. But they seem to fail when it comes to tumor cells. In JCI Insight, MDC teams led by Armin Rehm and Uta Höpken describe what inhibits this immune function, how they can release the brake and boost the immune response against cancer.
T cells are the immune system’s SWAT team. Their job is to constantly patrol the blood, lymphatic system, tissues, and organs. If they come across cells that are contaminated with or damaged by pathogens, they eliminate them. They can also recognize and destroy cancer cells. The problem, though, is that the tumor cells find ways of escaping this line of defense.
