Overview of a mature T-cell synapse. The immunological synapses (IS) is also termed supramolecular activation complexes (SMACs), including the central region of the supramolecular activation complex (c-SMAC), the peripheral ring surrounding the c-SMAC (p-SMAC), the region distal to the synapse outside the p-SMAC (d-SMAC) and the molecules/ligand pairs that are found enriched within. Protein myristoylation makes a significant contribution to IS formation.
