Immunology After the Signal's Gone, What's Left?
T cells are stimulated into action when they associate with other immune cells that present them with specific antigens. An intercellular synapse facilitates this intimate encounter and a prolonged engagement is thought to be required for T cell activation. Lee et al. (see the Perspective by van der Merwe and Davis) in fact show that signaling through the T cell receptor has abated by the time a mature immunological synapse has formed. The center of the mature synapse may not function as a supramolecular signaling complex as previously thought, which raises new questions about the function of this specialized and dynamic structure.
