The contact site between T cells and antigen-presenting cells or T cells and their targets--the immunological synapse--is a highly specialized structure potentially involved in T-cell activation and function. Although many insights have been obtained since the initial description of the immune synapse, recent advances have provided us with a better understanding of mechanisms involved in synapse formation and in the diversity of synapse morphologies. New potential roles for the synapse such as in polarized cytokine secretion or in adaptive control of T-cell activation have been proposed.

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
