The role of the immunological synapse formed by cytotoxic lymphocytes in immunodeficiency and anti-tumor immunity

Abstract

A synapse is a specialized structure that forms when the plasma membrane of two cells come into close contact to facilitate communication and signaling. Cells of the immune system form ‘immunological’ synapses that have an ordered structure and are essential for immune cell activation, function and homeostasis. Optimal synapse formation is not only critical for the generation of effective immunity against pathogens but is also essential for immune surveillance against cancer and for the prevention of immune disorders. Not surprisingly, defective synapse formation can therefore have severe consequences for human health, culminating in poor immune function leading to immunodeficiency disease o..
