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 ...
