In immunology, an immunological synapse (or immune synapse) is the interface between an antigen-presenting cell or target cell and a lymphocyte such as a T/B cell or Natural Killer cell. The interface was originally named after the neuronal synapse, with which it shares the main structural pattern. An immunological synapse consists of molecules involved in T cell activation, which compose typical patterns—activation clusters. Immunological synapses are the subject of muc… WebSep 11, 2007 · Quintana et al. noted that beads coated with antibodies to CD3, a constituent of the T cell receptor (TCR) complex, produced a larger and more sustained calcium signal in the Jurkat T cell line and primary human T cells than did the same antibodies in solution.
