Crosslinking beads immunolical synapse
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… WebDec 15, 2011 · The immunologic synapse defines the contact between an immune cell and an object of interest. While most work on immunologic synapses has been performed in T cells, there are many other examples of immune cells that use highly reproducible synapses to access or restrain contact-dependent effector functions.
