Explanation:
Detailed explanation-1: -Lymphocyte The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body’s own cells that have themselves been taken over by viruses or become cancerous.
Detailed explanation-2: -The cytokines released by helper T-cells help activate cytotoxic T-cells. Cytotoxic T-cells send out molecules to fight the infection. Cytotoxic T-Cells can also recognize cells that are infected and directly kill them to prevent further infection.
Detailed explanation-3: -They can act as “killer cells”, attacking cells which have been infected with a virus or another kind of pathogen, or they can act as “helper cells” by supporting B cells to produce antibodies.
