Lymphocytes called T-cells are responsible for fighting infections by recognizing antigens, binding to them and then releasing chemicals called cytokines. These cytokines multiply the number of B-cells, some of which are turned into plasma cells. Those cells secrete antibodies that circulate in the blood so that when they reencounter a specific antigen, they can bind to it, thereby signaling
