T cells communicate with antigen-presenting cells (APC) via the signaling crosstalk at the immunological synapse (IS). Here the authors use bead-supported lipid bilayers as synthetic APCs to find that trans-synaptic vesicles produced by T cells in the IS carry specialized cargos distinct from constitutive extracellular vesicles to serve as intercellular messengers.
