Immunological synapses are specialized intercellular contacts formed by several types of immune cells in contact with target cells or antigen-presenting cells. A late-stage immune synapse is commonly a bulls-eye pattern of immune cell receptor-ligand pairs surrounded by integrin complexes. Based on crystal structures, the intermembrane distance would be ∼15 nm for many immune cell receptor-ligand pairs, but ∼40 nm for integrin-ligand pairs. Close proximity of these two classes of intermembran...Expand abstract
