The immunological synapse coordinates intercellular communication between T cells and antigen-presenting cells, but the signaling functions of this structure have not been clear. Experiments and computer modeling have led Lee et al. to propose that T cell receptor (TCR) clustering in the synapse enhances receptor signaling but also potentiates a higher rate of TCR degradation--a type of adaptive control function that regulates the strength and duration of T cell signaling in response to a specific ligand.
