Immune cells get switched off by the gradual accumulation of dense clusters of inhibitory proteins

Foreign entities within the body get chopped into pieces by antigen-presenting cells (APCs), which display the resulting chunks on their surface. These antigens can subsequently be recognized and bound by T cell receptors (TCRs), and the interaction between a T cell and an antigen-bearing APC eventually triggers the onset of an immune response against the antigen.
