What happens when T cells detect suspicious activity in the body? Researchers from the TU Wien and the Medical University of Vienna have revealed that immune receptors of T cells operate in unsuspected ways. Every T cell receptor of the living T cell (left) is marked with a special marker molecule. The bottom part of the cell can be imaged with a highly sensitive microscope. An artificial cell membrane on a glass plate binds T cells. The T cell (top, in green) has receptors (blue), which are tagged with a fluorescent molecule. hey protect us from the onslaught of bacteria and viruses and also from cancer: T cells are an indispensable part of our immune system. They constantly renew their surface with thousands of highly sensitive T cell antigen receptors, which allow them to identify atypical or foreign molecules (antigens) in our body.
