T cell antigen receptors act alone: Longstanding immunological mystery solved

With a standard electron microscope, only dead T cells can be studied. Therefore, it is very hard to figure out the inner workings of the cell. New microscopy techniques, making it possible to study living T cells, have now led to surprising results: while it has been generally believed that T cell receptors must interact with one another for effective immune-signaling, the new study shows: T cell receptors act alone.
