In the lymphatic system, naive B cells encounter an antigen, which starts the maturation process for the B … WebHow are B and T cells activated? T and B cells are activated when they recognize small components of antigens, called epitopes, presented by APCs, illustrated in Figure 2. Figure 2. An antigen is a macromolecule that reacts with components of the immune system. A given antigen may contain several motifs that are recognized by immune cells.
